BMW suspects just 1 percent of the vehicles referenced in the recall contain the defective parts.
The Defect
Affected vehicles contain engine control unit-driven electric auxiliary water pumps that may overheat within high-temperature environments. Specifically, the circuit boards installed in these components are prone to heat due to a critical design flaw. Consequently, electric auxiliary water pumps using these circuit boards might overheat to an extent that causes smoldering, which in turn increases the likelihood of engine fire. This threat poses a serious safety hazard to occupants. However, BMW has yet to receive reports connecting the defect to any accidents or injuries.
Timeline of Events
BMW engineers first noticed instances of electric auxiliary water pump failureback in June 2009, according to an earlier defect report submitted to the NHTSA. This discovery prompted additional internal testing, which revealed an issue with the circuit board assemblies installed in the pumps. Later in September 2009, Mini, a BMW brand, discovered a vehicle that suffered electric auxiliary water pump failure. BMW initiated a field monitoring program in response.
In May and June 2010, the automaker came across two other vehicles that showed signs of engine compartment burning. This finding prompted BMW to form a special task force to address the issue. The group, in November 2010, confirmed that the vehicles experienced engine compartment fires due to electric auxiliary water pump failure linked to circuit board degradation. The company continued to monitor the field for the next year, during which time 81 vehicles worldwide suffered electric auxiliary water pump failure. Four of these vehicles experienced engine compartment fires.
In December 2011, BMW completed internal tests involving both BMW and Mini vehicles. On Jan. 3, 2012, the automaker initiated a voluntary safety recall involving more than 88,000 vehicles across both brands.
More than four years later in October 2017, BMW received a field report detailing an instance of electric auxiliary water pump failure in a 2011 Mini Cooper S. The company evaluated the vehicle referenced in the report and confirmed the root cause. BMW then found that this particular model was not included in the 2012 recall, which forced it to reassess its engineering and field data. This review revealed multiple instances in which BMW had inspected damaged vehicles that showed signs of electric auxiliary water pump failure, including BMW 550i and 750i sedans. The automaker then launched a formal review of the amended electric auxiliary water pump assemblies installed in vehicles following the 2012 recall campaign and found that these fixtures were failure-prone despite the presence of enlarged circuit path spaces, hall sensor holder gaps and improved plating and soldering.
BMW reviewed its production records and determined that models across its brand, Mini and Rolls Royce were affected. On April 11, 2018, the car manufacturer initiated another voluntary safety recall.
The Solution
BMW has directed dealers to replace the electric auxiliary water pumps in affected vehicles free of charge, according to an NHTSA recall acknowledgement document. However, the automaker is still developing replacement parts. That said, the company plans to reach out to owners June 11, and once more when replacement fixtures become available. Owners in need of assistance prior to the start of the recall can connect with BMW customer service personnel by calling (800) 525-7417. Mini owners should call (866) 825-1525, while individuals with recalled Rolls Royce vehicles should use (877) 877-3735. Owners can, of course, contact the NHTSA directly using its Vehicle Safety Hotline at (888) 327-4236.

Volkswagen recalls SUVs with defective suspension assemblies

Auburn Hills, Mich. – May 15, 2018 – Volkswagen Group of America has recalled more than 7,000 vehicles potentially equipped with defective suspension components, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects 2018 Volkswagen Tiguan sport utility vehicles produced between Jan. 15, 2018, and March 6, 2018, at the Volkswagen Mexico Factory in Puebla, Mexico. The German automaker suspects 32 percent of the vehicles contain the defective parts.
The Defect
Affected models contain rear shock absorbers with lower loops that could separate the base suspension assembly due to defective welds. Should separation occur, the rear shock absorber may detach, causing the vehicle to suddenly lose stability. This issue drastically increases the likelihood of an accident. The defect therefore poses a serious hazard to occupants. However, Volkswagen has yet to receive reports connecting the problematic suspension parts to any accidents or injuries.
Timeline of Events
While conducting post-production test drives between Feb. 19, 2018, and March 3, 2018, Volkswagen engineers at the Mexico facility encountered multiple vehicles that lost stability while in operation. This finding prompted the local engineering department to launch an internal quality analysis campaign. On March 26, 2018, Volkswagen engineers at the plant informed the Pre-Product Safety Committee, which called for further analysis and forwarded the issue to the Product Safety Committee. Soon after, Volkswagen found that the Lake Forest, Illinois-based supplier Tenneco had welded the lower loops with a misaligned arc torch and identified this production error as the root cause.
Both regulatory bodies met April 18, 2018, and decided that a voluntary safety recall was necessary.
The Solution
Volkswagen will direct dealers to replace the rear shock absorbers in affected vehicles free of charge, according to an NHTSA recall acknowledgement document. The automaker intends to inform dealers June 22, 2018, and reach out to owners via first-class mail June 25, 2018. Individuals with recalled vehicles in their possession who need more immediate assistance can contact Volkswagen customer service at (800) 893-5298. Callers should use the internal recall identification code 42i7. Owners can also connect with the NHTSA directly using the agency’s toll-free Vehicle Safety Hotline at (888) 327-4236.

Hyundai recalls vehicles with defective clutch components

Fountain Valley, Calif. – May 10, 2018 – Hyundai Motor America has recalled more than 10,000 vehicles potentially equipped with defective hydraulic clutch actuator assemblies, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects 2017 Hyundai Ioniq hybrid sport utility vehicles produced between Nov. 16, 2016, and Sept. 20, 2017. The South Korean automaker suspects 1 percent of the models involved in the recall contain the defective parts.
The Defect
Affected vehicles have hydraulic clutch actuator housings with abnormally rough edges. These defective features can damage the nearby oil seals, causing oil to leak and pool around the phase cap. This issue can cause electrical shorting and, in instances in which major thermal damage occurs, engine fire. As a result, the defect poses a serious risk to occupants. That said, Hyundai has yet to receive field reports linking the problematic hydraulic clutch actuator assemblies to any accidents or injuries.
Timeline of Events
A Hyundai parts provider LuK reached out to the car manufacturer in March 2017 to report that it had received hydraulic clutch actuator assemblies involved in warranty claims that seemed to exhibit signs of thermal damage near their phase caps, according to an internal chronology report given to the NHTSA. Hyundai reviewed warranty claims filed in the Korean market in response and found no reports of engine fire or thermal events of any kind. The automaker then began shipping parts from applicable warranty claims to LuK for further analysis. Within three months, the parts vendor had collected a large number of hydraulic clutch actuator assemblies whose housings featured jagged metal edges. LuK determined that these features could damage adjacent oil seals and cause leakage. Consequently, the firm implemented new production processes to eliminate the creation of jagged housing edges and installed reinforced oil seals to prevent leakage.
A Hyundai affiliate submitted a quality information report associated with the defect in December 2017. This action prompted the automaker to accelerate and expand its analysis efforts. Between January 2018 and April 2018, Hyundai combed through a significant number of hydraulic clutch actuator assemblies to gain more information on the variables contributing to failure. The car manufacturer was able to replicate an electrochemical reaction caused by oil pooling around the phase cap. It was also able to create a galvanic event that produced sparks and could cause an engine fire.
On April 16, 2018, Hyundai shared its findings with all vendors and affiliates in all markets. Then, on April 20, 2018, the automaker convened its Technical Committee, which called for a voluntary safety recall. Dealers received notification of the campaign May 4, 2018.
The Solution
Hyundai has directed dealers to inspect hydraulic clutch actuators installed in affected vehicles and, if necessary, replace these parts free of charge, according to an NHTSA recall acknowledgment document. The car manufacturer intends to reach out to owners through first-class mail June 20, 2018. Owners in need of assistance prior to the beginning of the campaign can contact Hyundai customer service personnel at (855) 371-9460. Callers should use the internal recall reference number 176. Owners can, of course, connect with the NHTSA directly via its toll-free Vehicle Safety Hotline at (888) 327-4236.

Kia recalls vehicles with defective clutch components

Irvine, Calif. – May 10, 2018 – Kia Motors America has recalled more than 27,000 vehicles potentially equipped with defective clutch components, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects 2018 Kia Niro hybrid sport utility vehicles produced between Nov. 1, 2016, and Sept. 11, 2017. The South Korean automaker suspects just 1 percent of the vehicles referenced in the action contain the defective components.
The Defect
Affected vehicles contain defective hydraulic clutch actuator assemblies with rough edges that may damage to the adjacent oil seal and cause oil to leak or accumulate near the phase cap. Should either of these events occur, the likelihood of electrical shorting and engine fire increases. Consequently, this defect poses a serious hazard to occupants. However, Kia has yet to receive reports connecting the defect to any accidents or injuries.
Timeline of Events
KMA on Dec. 7, 2017, notified its parent company via a quality information report that some 2018 Kia Niro hybrid SUVs were generating hydraulic clutch actuator trouble codes, according to an internal chronology report submitted to the NHTSA. Almost three weeks later, the Kia Motor Corporation initiated an investigation in response to the QIR. Throughout January and February 2018, KMC worked with suppliers to evaluate hydraulic clutch actuator assemblies installed in 2018 Kia Nitro hybrid SUVs. This collaborative inquiry revealed that oil was leaking within the actuator housing, causing the vehicle to generate an error code. Investigators were able to duplicate electrical shorting associated with the leakage but could not recreate thermal decay or engine fire.
Over the course of February and March 2018, KMC conducted more tests to confirm the root cause of the error codes mentioned in the original QIR. On April 16, 2018, the car manufacturer reviewed all available data related to the defective hydraulic clutch actuator assemblies and decided to conduct a voluntary safety recall.
The Solution
Kia will direct dealers to inspect the hydraulic clutch actuator assemblies installed in affected vehicles and install additional sealant or replace them free of charge, according to an NHTSA recall acknowledgement document. The automaker intends to notify dealers June 8, 2018, and reach out to owners via first-class mail June 15, 2018. Owners in need of assistance prior to the start of the recall can contact Kia customer service personnel at (800) 333-4542. Callers should use the internal recall reference code SC163. Owners can also connect with the NHTSA directly using the agency’s Vehicle Safety Hotline at (888) 327-4236.

Lamborghini recalls vehicles with defective weight limit labels

Bologna, Italy – May 10, 2018 – Automobile Lamborghini has recalled almost a dozen vehicles potentially equipped with defective weight limit labels, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects 2017 Lamborghini Centenario coupes and roadsters produced between March 13, 2017, and Oct. 27, 2017. The Italian automaker suspects all of the vehicles referenced in the action contain the defective labels.
The Defect
Affected vehicles contain manufacturer certification labels that list incorrect weight limits. This defect violates Federal Motor Vehicle Safety Standard 49, Part 567, which states that all models must come with labeling that displays accurate readings for gross vehicle weight rating and gross axle weight rating, according to the Government Publishing Office. In addition to violating FMVSS 49, Part 567, the defect poses a serious safety hazard to occupants, as the incorrect readings could lead owners to overload their vehicles and reduce maneuverability, increasing the likelihood of an an accident. However, Lamborghini has yet to receive reports connecting the defect to any collisions or injuries.
Timeline of Events
Lamborghini in April 2018 received a customer complaint referencing a 2017 Lamborghini Centenario that appeared to feature incorrect weight limit labels. While the report originated from outside of the U.S. market, the car maker determined that models with potentially incorrect manufacturer certification labels were sold in American dealerships. The Lamborghini Product Safety Committee reviewed the issue April 11, 2018, and determined that labels violated FMVSS 49, Part 567, necessitating a voluntary safety recall. Lamborghini notified dealers of the forthcoming action April 27, 2018.
The Solution
The automaker has directed dealerships in the U.S. to install corrected manufacturer certification labels in affected models free of charge, according to an NHTSA recall acknowledgement document. Lamborghini began sending out owner notifications via registered mail May 4, 2018, and will continue to reach out through June 4, 2018. Owners in need of further assistance can contact Lamborghini customer service personnel at (866) 681-6276. Callers should use the internal recall reference code L73XR0118. Of course, owners can connect directly with the NHTSA using the agency’s Vehicle Safety Hotline at (888) 327-4236.

Volkswagen recalls vehicles with defective Takata air bags

Auburn Hills, Mich. – May 10, 2018 – Volkswagen Group of America has recalled more than 71,000 vehicles potentially equipped with defective Takata air bag assemblies, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects 2006-2007 Volkswagen Passat sedans produced between April 27, 2005, and Nov. 3, 2006, as well as 2006-2007 Volkswagen Passat wagons produced between July 5, 2005, and Nov. 17, 2006. The German automaker suspects all of the models referenced in the recall contain the defective components.
The parts involved in this action are at the center of a multiyear recall campaign encompassing 42 million vehicles across more than one dozen brands, Car and Driver reported. Approximately 15 owners have perished in accidents involving these components, while more than 100 have sustained serious injuries, according to Consumer Reports.
The Defect
Affected vehicles contain Takata air bag assemblies with inflator modules whose propellant wafers are prone to degradation over time. These defective wafers could lead to particularly violent combustion upon air bag deployment. This issue, in turn, may cause the steel air bag inflator housing to explode, spraying metal fragments throughout the vehicle cabin at high speeds. Consequently, the defect poses a mortal threat to occupants. As stated above, Takata air bag assemblies are responsible for multiple driver deaths and injuries.
Timeline of Events
In March 2016, Volkswagen recalled more than 150,000 vehicles, including those involved in this action, in response to a Takata component recall filling, according to documentation from the NHTSA. The automaker oversaw permanent replacement of the air bag assemblies installed in these models, trading the defective inflators for replacements containing desiccated ammonium nitrate propellant. Recently, Volkswagen decided to adopt guanidine nitrate-based inflators. GuNi propellant is more durable and less caustic than ammonium nitrate propellant, The New York Times reported. This switch forced the car manufacturer to launch another recall, which it did April 18, 2018. Volkswagen also informed dealers of the impending action on this date.
The Solution
The automaker will replace the ammonium nitrate-based air bag inflators with GuNi alternatives free of charge, according to an NHTSA recall acknowledgement document. Volkswagen contacted owners via first-class mail April 30, 2018. Those in need of additional assistance can reach out to Volkswagen customer service personnel by calling (800) 893-5298 and using the internal recall identification code 69Q8. They can also connect with the NHTSA directly through the agency’s Vehicle Safety Hotline at (888) 327-4236.

Chrysler recalls SUVs with defective frame components

Auburn Hills, Mich. – May 4, 2018 – Chrysler Fiat Automobiles has recalled more than 100 vehicles potentially equipped with defective vehicle frame components, according to documentation submitted to the National Highway Transportation Administration. The campaign involves 2018 Jeep Wrangler sport utility vehicles produced between Oct. 15, 2017, and Oct. 16, 2017. FCA suspects roughly half of the vehicles referenced in the recall contain the defective parts.
The Defect
The affected vehicles feature frames with rear underbody ladder rails that are prone to premature corrosion and failure. In the event that ladder rail fails, the adjacent left rear seat mount may loosen. Additionally, ladder rail corrosion can weaken the structural integrity of the left rear floor pan. Together, these developments may increase the risk of occupant injury during an accident. However, FCA has yet to receive reports connecting the defective underbody ladder rails to any accidents or injuries.
Timeline of Events
In October 2017, FCA engineers discovered 2018 Jeep Wrangler underbody ladder rails that appeared to differ from other frame components. This finding prompted the FCA Vehicle Safety and Regulatory Compliance group to open official investigation into the matter. Over the course of November 2017 and December 2017, the VSRC organization collaborated with personnel from FCA Materials Engineering to assess the galvanized coating used on the underbody ladder rails, as the varnish seemed to exhibit depleted moisture protection capabilities. During this time, VSRC members also met with the Body Engineering team to better understand the initial design for the 2018 Jeep Wrangler.These safety and quality assurance stakeholders reviewed build data and parts receivable timelines, as well, using this information to determine the scope of the problem.
The VSRC group in January 2018 convened with FCA Safety Engineering experts to understand the various hazards created by potentially corroded underbody ladder rails. One month later, VSRC members received confirmation from the engineering group that the parts were indeed at risk of experiencing premature oxidization and could fail as a result. Throughout March 2018, the VSRC organization reviewed production data and determined the number of vehicles potentially affected. On April 5, 2018, the group met with the Vehicle Regulations Committee, and together, these two bodies decided a voluntary safety recall was necessary.
The Solution
FCA has yet to develop a solution to this issue. However, the automaker does intend to reach out to both owners and dealers June 1, 2018, according to an NHTSA recall acknowledgement document. Owners in need of assistance prior to the start of the recall can contact FCA customer service at (800) 853-1403. Callers should use the internal recall identification code U27. Owners can also connect with the NHTSA directly using its Vehicle Safety Hotline at (888) 327-4236.

Volkswagen recalls vehicles with defective engine coolant pumps

Auburn Hills, Mich. – May 4, 2018 – Volkswagen Group of America has recalled more than 342,000 vehicles potentially equipped with defective engine coolant pumps, according to documentation submitted to the National Highway Transportation Administration. The campaign affects multiple models across the Audi brand, including:
  • 2013-2016 Audi A4 sedans produced between Feb. 20, 2012, and Dec. 8, 2015.
  • 2013-2016 Audi A4 Allroad sedans produced between March 12, 2012, and April 1, 2016.
  • 2013-2017 Audi A5 Cabriolets produced between March 9, 2012, and Dec. 16, 2016.
  • 2012-2015 Audi A6 sedans produced between April 4, 2011, and Dec. 22, 2014.
  • 2013-2017 Audi Q5 sport utility vehicles produced between July 4, 2012, and Dec. 20, 2016.
Volkswagen suspects all of the vehicles involved in the recall contain the defective parts.
The Defect
The models referenced in this action are likely to include engine coolant pumps prone to overheating and short circuiting due to blocked ventilation components or internal moisture development. Both conditions increase the likelihood of an engine fire. Consequently, the defective pumps pose a serious risk to occupants. However, Volkswagen has yet to receive reports linking the problematic parts to any accidents or injuries.
Owners operating vehicles equipped with the defective features may see an engine warning light prior to overheating or short circuiting, depending on the engine control software present.
Timeline of Events
On Dec. 23, 2016, the Audi Product Safety Committee issued a voluntary safety recall, filed under the NHTSA identification code 17V-002, to address defective engine coolant pumps in more than 342,000 vehicles. Dealers across the U.S. market executed the required remedy in the months following the recall, updating the ECU software installed in affected models with new programming designed to switch off the engine coolant pump power supply in the event of overheating or short circuiting. Between March 2017 and August 2017, Audi received multiple complaints from customers outlining instances of overheating and short circuiting, despite the existence of the updated ECU software. The automaker requested parts review following these reports.
More customers submitted identical complaints throughout September 2017 and October 2017. These instances prompted Audi to launch more exhaustive field tests and laboratory analyses to identify error patterns, significant mechanical variables and ultimately pinpoint the root cause of the issue.These inquiries revealed that moisture, in addition to ventilation blockage, affected engine coolant pump performance.
Members of the Audi Product Safety Committee convened April 4, 2018, to review the results of the field and laboratory tests. These stakeholders decided that the engine coolant pumps in the affected vehicles should be replaced along with the ECU software and chose to call for a voluntary safety recall.
The Solution
As stated above, Audi intends to replace the engine coolant pumps and ECU software in recalled vehicles free of charge. However, replacement parts are not currently available, according to an NHTSA recall acknowledgement document. The automaker plans to notify both dealers and owners when these components are ready for installation. That said, Audi does intend to reach out to owners initially via first-class mail June 11, 2018, to prepare them for the forthcoming action. In the meantime, individuals in possession of recalled models can contact Audi customer service personnel at (800) 253-2834. Callers should use the internal recall reference code 19N3/19N4. Of course, owners can always contact the NHTSA directly using the agency’s Vehicle Safety Hotline at (888) 327-4236.

Hyundai recalls vehicles with defective safety features

Fountain Valley, Calif. – May 1, 2018 – Hyundai Motor America has recalled more than 580,000 vehicles potentially equipped with defective air bag and seat belt assemblies, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects 2011-2013 Hyundai Sonata sedans produced between Dec. 11, 2009, and Aug. 31, 2012, along with 2011-2012 Hyundai Sonata Hybrid sedans produced between Dec. 2, 2010, and Aug. 23, 2012. The South Korean automaker suspects all of the vehicles referenced in the recall contain the defective parts.
The Defect
Affected models contain air bag control units powered by application-specific integrated circuits. These components are designed to trigger advanced air bag systems and seatbelt pretensioners in the event of an accident. However, the ACUs installed in the recalled vehicles feature ASICs that lack circuit-protecting diodes. Without these electrical parts, the ASICs may experience overstress and eventually fail, inhibiting ACU functionality and leaving occupants without crash protection. Consequently, this defect poses a serious hazard to owners. Hyundai has received at least five reports linking the defective part to accidents and injuries.
Timeline of Events
The automaker in February 2012 received a report outlining an instance in which the AAS in a 2011 Hyundai Sonata seemed to fail during an accident, according to an internal chronology document submitted to the NHTSA. Hyundai engineers inspected the vehicle referenced in the report in June 2012 and found that the vehicle had not recorded a crash event. The car company then reached out to the Michigan-based supplier ZF TRW, which had provided the ACU components installed in the vehicle. The vendor discovered signs of electrical overstress within the ACU’s ASIC assembly, a condition it linked to a number of aftermarket accessories that were installed on the model referenced in the report.
Hyundai in May 2015 received a report detailing another instance of AAS non-deployment. In October 2015, engineering teams inspected the vehicle, a 2011 Hyundai Sonata, and determined that the ACU was not functioning. ZF TRW reviewed the component and again found signs of electrical overstress. The vehicle did not contain aftermarket parts, indicating that the condition may not be linked to the installation of such non-standard components. As a result, Hyundai initiated a field review.
The automaker received two additional reports centered on AAS non-deployment between July and November 2016. While one was invalidated by investigators, the second involved a 2011 Hyundai Sonata sedan with potential ASIC damage linked to overstress. Hyundai launched an official investigation in response. Then, in November 2017, OSHA’s Office of Defects Investigation contacted the car company to check on the status of the inquiry. Hyundai submitted data related to the investigation and established a communication channel for updates. One month later, the automaker hired an external engineering firm to look into the ACU issue.
On February 21, 2018, Hyundai and ZF TRW met to discuss the state of the ongoing investigation, with the latter coming to the conclusion that transient charges, originating from adjacent vehicle parts, were causing electrical overstress in the ASIC assemblies and therefore affecting ACU performance. One day later, members of Hyundai’s Technical Committee convened and determined that a voluntary recall involving affected 2011 Hyundai Sonata sedans was necessary. Following this action, the automaker continued its investigation into the problematic ACU components.
ODI officials and Hyundai met in Washington D.C. March 9, 2018, to discuss the inquiry and the initial findings from the third-party engineering firm. It was during this meeting that Hyundai revealed that its external collaborator had determined that the ACU failure was the result of equipment failure – specifically a lack of circuit-protecting diodes. The automaker attested to replicating the equipment-related damage in a series of crash tests. This discovery expanded the pool of potentially affected models to include Hyundai Sonata and Sonata Hybrid sedans produced in 2012 and 2013. On April 3, 2018, the two parties met once more to review the ongoing investigation.
Between April 11, 2018, and April 12, 2018, Hyundai collaborated with ZF TRW to review the ACU damage sustained in the previously conducted crash tests. Both automaker and vendor agreed hat the ASIC assemblies in these components shorted due to lack of diodes. On April 18, 2018, the Hyundai TC decided to expand the existing recall, an action the group communicated to both dealers and owners April 20, 2018.
The Solution
Hyundai has not yet developed a viable remedy, according to an NHTSA recall acknowledgment document. Owners in need of assistance can contact Hyundai customer service personnel by calling (855) -371-9460. Callers should use the internal recall identification number 174. Owners can also reach out to the NHTSA directly using the agency’s Vehicle Safety Hotline at (888) 327-4236.
