GM recalls vehicles with defective fuel system parts

 

Warren, Mich. – June 27, 2018 – General Motors has recalled almost 850 vehicles potentially equipped with defective fuel system components, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects vehicles across multiple brands, including:

  • 2018 Buick LaCrosse sedans produced March 27, 2018, and April 20, 2018.
  • 2018 Cadillac ATS sedans produced March 20, 2018.
  • 2018 Chevrolet Equinox sport utility vehicles produced between March 26, 2018, and April 20, 2018.
  • 2018 Chevrolet Colorado pickup trucks produced March 22, 2018, and April 27, 2018.
  • 2018 Chevrolet Malibu sedans produced between April 19, 2018, and April 27, 2018.
  • 2018 GMC Arcadia sport utility vehicles produced between April 5, 2018, and April 23, 2018.
  • 2018 GMC Canyon pickup trucks produced between March 23, 2018, and April 24, 2018.

GM suspects all of the vehicles referenced in the recall contain the defective components.

The Defect

Affected vehicles contain high-pressure fuel pump’s whose housings are not properly welded nearby flanges. These faulty welds could crack over time, resulting in fuel pump flange separation. Should this occur, the pump may oscillate within the engine compartment, leading to fuel leakage and, in some cases, fire. This defect therefore poses a serious risk to owners. However, GM has yet to receive field reports connecting the problematic parts to any accidents or injuries.

Timeline of Events

On April 25, 2018, Robert Bosch LLC, the vendor that supplied the fuel pumps installed in the recalled vehicles, contacted GM to disclose the potential existence of problematic housing and flange welds. The American automaker opened an official investigation into the issue May 5, 2018. While this inquiry uncovered zero occurrences of fuel leakage, GM determined, via Bosch engineering analysis, that the faulty fuel pump welds could fracture and lay the groundwork for this dangerous outcome.

Members of the GM Safety Field Action Decision Authority conducted a final review May 24, 2018, and determined that a voluntary safety recall was necessary.

GM notified dealers of the impending action May 31, 2018.

The Solution

The car manufacturer has yet to develop a workable solution, according to an FAQ document. There is therefore no timetable for owner notification. However, GM is working with Bosch to create a cost-free fix. Owners in need of assistance prior to the start of the recall can connect with GM customer service personnel by calling (866) 522-9559. Individuals in possession of recalled vehicles can also reach out to the NHTSA directly using its Vehicle Safety Hotline at (888) 327-4236.

GM recalls vehicles with defective engine software

 

Warren, Mich. – June 27, 2018 – General Motors has recalled almost 500 vehicles potentially equipped with defective engine software, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects 2019 Chevrolet Corvette ZR1 sports cars manufactured between Dec. 8, 2017, and May 31, 2018. The American automakers suspects just 1 percent of the models involved in the action contain the defective software.

The Defect

Affected vehicles come with sensing diagnostic module software that may fail when exposed to hard braking or extreme acceleration. In the event of SDM failure, crash sensing and air bag deployment functionality may be inhibited. This defect therefore poses a serious safety risk to occupants. However, GM has yet to receive field reports connecting the defective software to any accidents or injuries.

Owners in possession of vehicles that have experience SDM failure will not receive airbag readiness or diver information center notifications.

Timeline of Events

GM personnel on April 30, 2018, hosted a media demonstration in Atlanta, during which a 2019 Chevrolet Corvette ZR1 was subjected to race-like driving conditions. Following the event, GM engineers assessed the vehicle and found that its SDM software was not operating properly. These technical specialists brought the issue to the attention of the automaker May 3, 2018, via an internal Speak Up For Safety report. GM opened an investigation in response May 8, 2018.

During this inquiry, the engineering team at the GM Proving Grounds in Milford, Michigan conducted road tests involving hard braking and extreme acceleration. Following these trials, the group reviewed vehicle performance data and concluded that such maneuvers caused SDM overstress, which in turn led to complete software failure.

The GM Open Investigation Review evaluated the the matter May 21, 2018, before sending it to the Safety Field Action Decision Authority. The SFADA ultimately decided that a voluntary recall was necessary and initiated such action May 24, 2018.

GM notified dealers of the forthcoming campaign May 31, 2018.

The Solution

The automaker has directed dealers to reprogram the SDM software in affected models free of charge, according to an internal communication. GM intends to notify owners via first-class mail June 29, 2018. Owners in need of more immediate assistance prior to the start of the recall can contact GM customer service at (866) 522-9559. They can also connect with the NHTSA directly using its Vehicle Safety Hotline at (888) 327-4236.

GM recalls over 3,000 Volts due to software glitch affecting battery

 

Warren, Mich. – June 25, 2018 – General Motors LLC has recalled several thousand of its Chevrolet Volt models due to a software update flaw that may adversely affect the plug-in vehicle’s battery functionality, according to documentation submitted to the National Highway Traffic Safety Administration. The automaker believes the recall is warranted because affected cars may result in a crash, especially in situations where drivers need to accelerate to keep pace with the flow of traffic.

The Defect

Earlier this month, GM recalled approximately 3,233 Chevrolet Volts – with 2013 model years – after dealers performed a software update of the plug-in hybrid’s on-board battery, specifically its Hybrid Powertrain Control Module 2 or HPCM2. The update was meant to improve the life and sustainability of the HPCM2, but some of the software updates were corrupted, the company believes, potentially resulting in a voltage imbalance situation between the individual cells that give the plug-in hybrid the energy it needs to operate. Should the voltage dip below a certain threshold, the vehicle may enter a reduced power mode, thus preventing motorists from accelerating.

Although General Motors suspects just 2 percent of the 3,200+ Volts are affected, the automaker contends the recall is warranted because motorists operating the Volts with the flaw are at an increased risk for a crash due to a loss of propulsion that impacted vehicles may experience. No known crashes, injuries or deaths have been linked to the improper cell balancing defect.

Timeline of Events

The issue first came to light in May, when a GM engineer discovered the problematic software and informed GM of the issue after filing a Speak Up for Safety report, based on a chronology of events submitted to and published by the NHTSA. GM subsequently launched an investigation, although the automaker was already looking into a similar but unrelated issue relating to low-voltage output. The investigation revealed that the likelihood of Volts losing propulsion seemed to depend upon whether the vehicles had received a software update.

By June 7, GM’s Safety and Field Action Decision Authority determined that a safety recall was appropriate out of an abundance of caution.

The Solution

GM says it will inform owners of 2013 Volts about the software glitch, who can then go to their nearest dealership to have their HPCM2 reprogrammed for free, according to an NHTSA internal briefing document. The reprogramming will entail an update to the Volt’s vehicle interface control modules. However, GM didn’t say when the notifications would be sent out or how motorists will be informed. All of the affected Volts were sold within the continental U.S.

Owners who believe they may be impacted may get in touch with their Chevrolet dealer by dialing the toll free number at 1-800-222-1020. The reference number for this specific recall is 18215.

Alternatively, drivers may also go to NHTSA’s website at www.safercar.gov or call the Department of Transportation Vehicle Safety Hotline at 1-888-327-4236.

GM recalls vehicles with defective safety equipment

Warren, Mich. – General Motors has recalled almost 13,000 vehicles potentially equipped with defective safety equipment, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects multiple models across three GM brands, including:
  • 2009-2018 Chevrolet Express passenger vans produced between Sept. 9, 2008, and March 23, 2018.
  • 2009-2014 Chevrolet Silverado Heavy Duty pickup trucks produced between Oct. 13, 2008, and Nov. 6, 2013.
  • 2009 GMC 5000, 6000, 7000 and 8000 Series pickup trucks produced between Aug. 20, 2008, and July 31, 2009.
  • 2009-2018 GMC Savana passenger vans produced between Sept. 12, 2008, and March 10, 2018.
  • 2009 Isuzu F Series diesel commercial trucks produced between Aug. 20, 2008, and Dec. 19, 2008.
GM suspects all of the vehicles involved in the action contain the defective components.
The Defect
Affected vehicles come with portal fire extinguishers that clog easily may become inoperable in the event of an engine fire. Additionally, individuals who attempt to unclog them by force may sustain injury due to nozzle detachment. As a result, these components pose a serious hazard to occupants. However, GM has yet to receive field reports linking these fixtures to any accidents or injuries.
Timeline of Events
Personnel from the Isuzu Technical Center of America on Nov. 4, 2017, learned that fire extinguisher supplier Kidde had recalled a large number of defective products, according to an internal chronology document given to the NHTSA. Isuzu quickly reviewed its production records and found that many vehicles, including some Chevrolet trucks, included these components. On Nov. 14, the brand issued a voluntary recall. Three days later, GM began reviewing historic production records dating back decades to see if other past models had been equipped with the defective extinguishers, some of which could have been used in vehicles assembled in the 1990s and early 2000s. The automaker conducted this review over the course of nearly three months, evaluating production documents dating from 1992 to the present.
By January 2018, GM had identified approximately 100 different fire extinguisher models used across several brands. Engineers managed to trim this number to 13 – all of which Kidde manufactured – by March. Members of the GM Open Investigation Review assessed this data and transferred the case to the Safety and Field Action Decision Authority, which chose to conduct a voluntary safety recall April 19. GM notified dealers of the forthcoming action April 26.
The Solution
GM intends to notify owners via first-class mail when replacement parts are available, according to an NHTSA recall acknowledgement document. By this point, owners will need to contact Kidde directly to receive replacement extinguishers free of charge. Owners in need of additional assistance prior to or after the start of the recall can contact GM customer personnel at (800) 462-8782. Callers should use the internal recall identification number 18146. Owners can also reach out to the NHTSA directly using the agency’s Vehicle Safety Hotline at (888) 327-4236.

GM recalls vehicles with defective fuel sensors

 

Warren, Mich. – Nov. 21, 2017 – General Motors has recalled more than 35,000 vehicles potentially equipped with defective fuel tank sensors, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects 2011-2015 Chevrolet Silverado 3500 and GMC Sierra 3500 pickup trucks produced between May 24, 2010 and Sept. 30, 2015. GM believes all of the vehicles named in the recall contain the defective parts.

The Defect

Affected models include dual fuel tank assemblies. The first of these tanks includes a defective fuel-level sensor that sometimes stalls in the lowest position, offering an inaccurate reading and increasing the likelihood of overfilling and tank expansion. This, in turn, could then allow the tank to come into contact with the moving driveshaft, creating a hole and causing fuel leakage. As a result, the defect poses a serious threat to occupants. However, GM has received no reports linking the defective component to any accidents or injuries thus far.

Timeline of Events

In April 2017, the NHTSA notified GM about a vehicle owner questionnaire it had received that detailed an instance of fuel leakage in a 2015 GMC Silverado 3500 pickup. One month later, the GM engineers familiar with the VOQ submitted a report via the company’s Speak Up For Safety program. The automaker launched an internal investigation in response to the submission on May 16.

Over the course of May, June and July, engineers evaluated field data to pinpoint the root cause of the leakage, which apparently initiated in the front fuel tank. On July 27, GM met with the NHTSA to review the results of the three-month inquiry. The two parties came to the conclusion that the fuel leaks were not developing in vehicles manufactured after 2015. In August, GM completed a design failure mode and affect analysis, and determined that the problem was confined to Chevrolet Silverado 3500 and GMC Sierra 3500 trucks equipped with dual fuel tanks. These vehicles were manufactured without beds and other conventional pickup features, as they were intended for commercial use or modification.

GM personnel reviewed the matter in two separate sessions on Aug. 28 and Sept. 25. The NHTSA revaluated the defect on Oct. 2 as well. The GM Safety and Field Action Decision Authority looked over the issue Oct. 12 and decided to conduct a voluntary safety recall. GM notified dealers Oct. 19.

The Solution

GM has directed dealers to inspect the front fuel tanks in the affected models and either replace the rear tank fuel pumps or updated the fuel sensor software, according to an NHTSA recall acknowledgement document. These fixes, which will be ready for implementation in early 2018, are to be executed free of charge. The automaker plans send an initial notification to owners via first-class mail Dec. 18 and follow-up document in February 2018, when the remedy is ready for implementation. Owners in need of more immediate assistance can contact Chevrolet customer service at (800) 222-1020 or GMC customer service at (800) 462-8782. Callers should use the GM recall identification number 17399.

Owners can also contact the NHTSA directly using the toll-free Vehicle Safety Hotline at (888) 3274236.

GM recalls vehicles with defective air bags

 

Warren, Mich. – Nov. 9, 2017 – General Motors has recalled more than one-dozen vehicles potentially equipped with defective air bag assemblies, according to documentation filed with the National Highway Transportation Safety Administration. The campaign affects multiple models across two brands, including:

  • 2015-2016 Chevrolet Colorado pickup tucks produced between Oct. 10, 2014 and Feb. 6, 2016.
  • 2016 Chevrolet Volt electric sedans produced between Oct. 16 and Dec. 14, 2015.
  • 2015-2016 GMC Canyon pickup trucks produced between Oct. 13, 2014 and Aug. 2, 2015.

GM suspects that all of the vehicles referenced in this recall contain the defect components.

The Defect

Affected vehicles include driver-side front air bag assemblies with second-stage inflators that may malfunction upon deployment, thus failing to completely fill the corresponding air bags or do so within the regulated time span. This poses a serious risk to drivers involved in collisions, as they are less protected and therefore more likely to sustain injuries upon impact. However, GM has yet to receive reports connecting the defective air bag assemblies to any injuries or accidents.

Timeline of Events

In March 2016, GM recalled more than 1,500 vehicles after its air bag supplier, Key Safety Systems, discovered that some of its shipped frontal air bag assemblies failed to meet cold-weather fill-time requirements, according to an NHTSA Safety Recall Report. Specifically, these fixtures came equipped with second-stage inflators without the chemical mixture required to effectively facilitate deployment and fill frontal air bags as much or as quickly as required by law.

In the months following the March 2016 recall, KSS evaluated its inflators to determine whether mistakes were made during assembly or problems developed due to long-term vehicle use. During this analysis, the parts provider discovered another batch of defective filters that had been shipped to GM and installed in vehicles not referenced in the March 2016 action. KSS notified GM of the issue May 4, 2017. Approximately six days later, the automaker opened an internal investigation to better understand the problem.

Over the next four months, GM and KSS worked together to analyze the filters received during the March 2016 recall. This data allowed KSS to improve the accuracy of its existing strategy for detecting incorrectly assembled inflators, which involved the evaluation of component weight. The parts provider used this methodology to find defective inflators installed in non-recalled GM vehicles.

With this new information in hand, the GM Safety and Field Action Decision Authority elected to issue a voluntary safety recall Sept. 28. The car manufacturer notified dealers Oct. 5.

The Solution

GM has directed dealers to replace the driver-side frontal air bag assemblies in affected models free of charge, according to an NHTSA recall acknowledgment document. The automaker plans to notify owners via first-class mail Dec. 4. Those in need of more immediate assistance can contact Chevrolet customer service at (800) 222-1020 or GMC customer service at (800) 462-8782. Callers should use the internal GM recall identification number 17387. Owners can also reach out the NHTSA directly using its toll-free Vehicle Safety Hotline at (888) 327-4236.

GM recalls SUVs with defective drive shafts

 

Warren, Mich. – Aug. 31, 2017 – General Motors has recalled a number of sport utility vehicles believed to be equipped with defective drive shafts, according to documentation filed with the National Highway Transportation Safety Administration. The campaign affects 2017-2018 GMC Arcadia, 2018 GMC Terrain and 2018 Chevrolet Equinox models. The automaker estimates that 3 percent of the vehicles have problematic drive shafts.

The Defect

Models referenced in the recall could contain front right intermediate drive shaft assemblies prone to fracture and separation. Engineers have traced the issue to the parts manufacturer Nexteer, which failed to use properly calibrated ultrasonic scanning equipment when performing quality checks.

The defect poses a serious safety hazard to occupants, as vehicles with damaged drive shafts may lose power during operation or roll away when stopped without the parking brake engaged. However, GM has yet to receive reports of accidents or injuries connected to the defect.

Timeline of Events

On July 20, 2017, engineers at the GM assembly facility in San Luis Petosi, Mexico, came across a newly manufactured GMC Terrain sport utility vehicle with a separated right intermediate drive shaft. Quality assurance reviewed the part and confirmed, via Nexteer records, that it had passed end-of-line inspection before being shipped to the assembly site. From July 21-27, engineers at the plant discovered three additional fractured drive shafts, all of which had also passed the final quality check at Nexteer. On July 28, officials at the San Luis Petosi plant filed a report via GM’s “Speak Up for Safety” program.

Nexteer analyzed its records and discovered that drive shaft assemblies produced between June 13 and July 21 were scanned with improperly calibrated ultrasonic scanning equipment. The parts provider confirmed that drive shafts from this batch had been shipped to four separate GM plants, including the San Luis Petosi facility. GM then initiated quarantine programs at these sites. On Aug. 1, Nexteer delivered properly calibrated ultrasonic scanners to the GM assembly facilities, where all vehicle drive shafts were scanned.

GM opened an investigation into the matter Aug. 4., and concluded the inquiry Aug. 14. On Aug. 15, the GM Safety Field Action Decision Authority called for a voluntary safety recall. The car manufacturer notified dealers Aug. 22.

The Solution

GM has asked dealers to replace the front right intermediate drive shafts in affected vehicles free of charge, according to a document submitted to the NHTSA. The company has yet to release a timetable for notifying owners. However, those in need of immediate assistance can call Chevrolet and GMC customer service representatives at (800) 222-1020 and (800) 462-8782. They can also call the NHTSA Vehicle Safety Hotline at (888) 327-4236.

GM recalls trucks with faulty EPS software

 

Warren, Mich. – Aug. 15, 2017 – General Motors has recalled nearly 700,000 vehicles suspected of containing faulty electronic power steering software, according to documents filed with the National Highway Transportation Safety Administration. The campaign affects 2014 Chevrolet Silverado LD pickup trucks manufactured between Jan. 30, 2013 and Sept. 4, 2014, as well as 2014 GMC Sierra LD pickups with production dates ranging from Jan. 29, 2013 to Sept. 4, 2014. GM estimates that 2 percent of the vehicles named in the recall contain the defective EPS software.

The Defect

Vehicles referenced in the recall could potentially contain EPS software prone to sudden shutoff during low-voltage maneuvers such as low-speed turns. The software normally fails within a one-second span, when system voltage measurements drop below 8.8 volts. With the EPS disabled, operators have difficulty navigating the vehicle. This poses a serious safety risk to owners, passengers and other drivers. However, GM has yet to receive any field reports connecting the defective software to any accidents or injuries.

Timeline of Events

On Feb. 2, 2017 GM opened an internal investigation into EPS software installed in some vehicles after receiving multiple customer complaints and vehicle owner’s questionnaires mentioning momentary loss of EPS function. Throughout February and April, the automaker reviewed the collected customer complaints, warranty claims and VOQs to determine if the vehicles referenced in these reports shared similar mechanical features. GM did indeed find technical links between the models and launched an extended field investigation to gather more data, eventually discovering that faulty software was the root cause of the EPS failures.

Over the course of April and May, GM engineers conducted internal tests at the company’s testing facility in Milford, Michigan in an effort to recreate the and evaluate the EPS problem. The automaker was able to gain a deeper understanding of the defective software and its impact on driveability. Engineers discovered that the EPS software stalled in particularly low-voltage situations and required at least 9 volts of electricity to maintain proper operations.

In June, the GM Open Investigation Review re-evaluated the original reports collected in February. On June 22, the car company’s Safety Field Action Decision Authority announced that an official safety recall was necessary. GM notified dealers of the campaign Aug. 7, according to internal documentation submitted to the NHTSA.

The Solution

The automaker has ordered dealers to update the EPS software in affected models with a new iteration released May 19. The repairs are to be administered free of charge. GM plans to notify owners via first-class mail beginning Aug. 15. Those in need of more immediate assistance can contact GM customer service at (800) 462-8782 or the NHTSA Vehicle Safety Hotline at (888) 327-4236.
