GM Recalls More Than 150 Vehicles for Damaged Airbag Modules

Laguna Hills, CA – December 27, 2018 – General Motors LLC (GM) is recalling certain 2019 Chevrolet Silverado 1500 Crew Cab and GMC Sierra 1500 Crew Cab vehicles due to potential issues with airbag modules. The potential number of units affected is 154.

The Defect

According to the NHTSA notification, these vehicles have a retainer ring within the passenger-side airbag module that may have been damaged during the assembly process. This damage could allow gas to escape during airbag inflation and deployment, which would reduce the amount of gas available to fill the airbag. Since the passenger-side frontal air bag module in affected vehicles may have been damaged during assembly, possibly resulting in the air bag not inflating properly in the event of a crash, the risk of injury is significantly increased if a crash does occur.

Timeline of Events

On December 6, 2018, the manufacturer notified Gm of the issue. On December 17, 2018, General Motors LLC (GM) informed the NHTSA. On December 26, 2018, the recall began. This recall is not connected to the widespread Takata airbag recall which has been ongoing, and affected certain Saab, Chevrolet, Pontiac, Saturn and GMC models.

The Solution

GM will notify owners, and dealers will replace the passenger side air bag module, free of charge. The recall began on December 26, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020 and GMC customer service at 1-800-462-8782. GM’s number for this recall is N182198820.

Courtesy transportation is available for customers whose vehicles are involved in a product program and still within the warranty coverage period. Owners may also call the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153). The NHTSA Campaign Number for this recall is 18V-868.

GM Recalls Several Vehicles for Air Bag Deployment Issues

Laguna Hills, CA – November 27, 2018 – General Motors LLC (GM) is recalling certain 2019 Buick Encore, Chevrolet Spark, Traverse, and Trax vehicles due to a potential air bag deployment issue. The potential number of units affected is 12.

The Defect

According to the NHTSA Recall Safety Report, in a small number of the listed vehicles, the sensing diagnostic module (SDM) may have been left in “manufacturing mode” and not activated at the assembly plant prior to shipment. If the SDM is in manufacturing mode, the vehicle’s airbags will not deploy in a crash, increasing the risk of occupant injury. Most other functions controlled by the same module, such as seatbelt reminder, event data recording and post collision notification, will also be inactive. Drivers may receive advance notice of this issue via the airbag/supplemental inflatable restraint malfunction indicator lamp on the instrument panel, which will illuminate and remain illuminated (solid or flashing) after the vehicle is turned on.

Timeline of Events

On October 3, 2018, a vehicle in GM’s Bupyeong, Korea plant was discovered to have a flashing airbag warning light after passing validation testing. GM subsequently started an investigation into the issue, which determined that the vehicle’s sensing and diagnostic module (SDM) was set to “manufacturing mode;” when in this setting, the SDM is unarmed and the supplemental inflatable restraints are disabled.

GM further determined that the condition’s root cause is an error in a software update to GM’s production process at certain plants. When the module is originally programmed during vehicle assembly, GM sets it to manufacturing mode which is designed to prevent accidental restraint and air bag deployment when the vehicle is in the assembly facility. Once full assembly is complete, all GM vehicles are subjected to a series of quality tests called dynamic vehicle tests (DVT), and at the conclusion of this process, the vehicle’s sensing diagnostic module (SDMs) is activated, which arms the restraints.

The error which was discovered in the software update can prevent the SDM from being activated in some vehicles at the conclusion of DVT. Due to this error, which only affected 12 vehicles, on October 25, 2018, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall.

The Solution

GM will notify owners, and dealers will reprogram the SDM module to the correct mode, free of charge. The recall began November 6, 2018. Owners may contact Buick customer service at 1-800-521-7300 and Chevrolet customer service at 1-800-222-1020. GM’s number for this recall is 18365. Owners may also call the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153). The NHTSA Campaign Number for this recall is 18V-774.

GM Recalls over One Million 2015 Vehicles Due to Faulty Steering Assist

 

Lilburn, Georgia – September 22, 2018: General Motors has discovered a defect which relates to motor vehicle safety exists in certain 2015 model year Chevrolet Silverado LD, Suburban, and Tahoe vehicles; GMC Sierra LD and Yukon vehicles; and Cadillac Escalade vehicles. GM has issued a recall for over one million vehicles.

The Defect

According to the NHTSA Safety Recall Report, the affected vehicles may experience a temporary loss of EPS assist, followed by a sudden return of EPS assist. This is most likely to happen during low-speed turning maneuvers. The loss and sudden return of EPS assist typically occurs within a 1 second period. The steering malfunction is caused by an electrical/software issue.

The danger lies in the fact that if EPS assist is lost and suddenly returned, the driver could have difficulty steering the vehicle. The likelihood of a crash is increased, especially at low speeds. Low speed turns can cause temporary low voltage conditions, and if system voltage drops below 8.8 volts for more than 1 second, EPS assist is disabled. When voltage returns to 9 volts for a minimum of 40 milliseconds, EPS assist returns.

If power steering assist is lost a driver information center message may alert the driver to an EPS problem, and other electrical sub-systems may shut down just prior to or at the same time as the EPS event, which can cause disruption to operation of the radio, stabilitrack, the DIC, chimes, door-lock cycling, air conditioning, or cruise control.

Timeline of Events

In late June 2018, an increase in field reports and customer complaints about EPS issues led GM to open a safety investigation into loss of EPS in the subject vehicles.  GM’s safety investigator and engineering-analysis experts determined the loss-of-EPS issues was caused by the same electrical issue discovered in trucks that GM recalled in 2017. GM’s Safety Field Action Decision Authority subsequently chose to conduct a safety recall.

The Solution

According to an NHTSA FAQ published for the recall, customers who own a vehicle involved in the field action will be notified by mail by General Motors, but the exact date the recall will begin is not yet set and the manufacture has not published a notification schedule.

Dealers will perform a reflash of the EPS module software. The inspection/repair will be done at no cost to the customer, and is available at Cadillac, Chevrolet and GMC dealers. Customers are strongly urged to repair their vehicle as soon as possible.

Courtesy transportation is available for customers whose vehicles are involved in the recall, and whose vehicles are still within the warranty coverage period for the warranty which is associated with the recall.

Owners may contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153) or check their Vehicle Identification Number (VIN) for field actions in GM Owner Center at my.gm.com/recalls or via NHTSA’s website at vinrcl.safercar.gov/vin/.

Owners may also contact manufactures directly: Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020 and GMC customer service at 1-800-462-8782. GM’s number for this recall is 18289.

GM recalls vehicles with defective passenger presence systems

 

Warren, Mich. – July 13, 2018 – General Motors has recalled more than five dozen vehicles potentially equipped with defective passenger presence systems, according to documentation submitted to the National Highway Transportation Safety Administration.

The campaign affects 2016-2018 Chevrolet Malibu sedans produced between Nov. 20, 2015, and Sept. 8, 2017. The American automaker suspects all of the vehicles involved in the action contain the defective components.

The Defect

Affected models contain replacement PPS assemblies that were installed as part of an earlier service initiative. However, these features, which are designed to detect seated passengers and signal the air bags to deploy in the event of an accident, contain miscalibrated parts.

These flawed components may cause the PPS software to misclassify children or smaller adults, inhibiting air bag functionality during collisions. The defect therefore poses a serious safety hazard to passengers. That said, GM has yet to receive reports connecting the problematic PPS assemblies to any accidents or injuries.

Timeline of Events

On Feb. 8, 2018, a GM engineer managing the PPS replacement initiative noticed that the part numbers for a number of the substitute PPS assemblies installed in 2016-2018 Chevrolet Malibu sedans were incorrect. This error indicated that some dealers may have installed the wrong replacement parts in some vehicles – specifically, PPS software not calibrated to the correct vehicle seat position.

Five days later, the design release engineer who discovered the issue notified the GM corporate office via the company’s Speak Up For Safety program. The engineer then began releasing work orders in an effort to address the issue proactively and did so until March 14, 2018.

On March 16, 2018, GM launched an official internal investigation. The automaker found that the GM engineering team had released two replacement PPS assemblies as part of the earlier repair initiative: one made for vehicles with vented seats and another made for vehicles with non-vented seats. Due to a part numbering mishap, these two components were mislabeled, meaning a number of dealers had likely installed incompatible parts in numerous 2016-2018 Chevrolet Malibu sedans and had unknowingly created a serious safety hazard.

GM evaluated the issue May 25, 2018, and decided that a voluntary safety recall was necessary.

The automaker informed dealers June 14, 2018.

The Solution

GM has directed dealers to replace the front PPS assemblies in affected vehicles free of charge, according to an NHTSA recall acknowledgment document. However, the car manufacturer has yet to release an owner notification timetable.

Owners in need of assistance can speak with GM customer service personnel by calling (800) 222-1020. Callers should use the internal recall identification number 18208. Owners can also reach out to the NHTSA directly using the agency’s Vehicle Safety Hotline at (888) 327-4236.

GM recalls vehicles over software update error

 

Warren, Mich. – June 29, 2018 – General Motors has recalled an estimated 3,233 vehicles after a recent update to the Hybrid Powertrain Control Module 2 could potentially disable the cell balancing function and result in a low-voltage condition. The recall affects select 2013 Chevrolet Volts, according to documents from the National Highway Transportation Safety Administration. The estimated figure of cars with this particular defect is 2 percent.

The Defect

Vehicles that received a software updated in a service procedure from a dealer may contain an error in the software update that could prevent the batteries from balancing the voltage in singular battery cells. Under certain circumstances, this may result in a low-voltage condition in one or multiple battery cells. The vehicle will notify drivers if the battery cells fall below a certain level and if the driver continues on the road after entering reduced power mode, the vehicle may lose propulsion. This incident may increase the risk of crash and injury.

Timeline of Events

A GM engineer sent in a Speak Up For Safety report on May 11 after finding that a software update used on select 2013 model-year Chevrolet Volt vehicles contained an error that could potentially prevent batteries in some of these vehicles from effectively balancing the voltage among individual battery cells, according to internal reports. Following this report’s submission, GM launched an investigation, where the investigator reviewed field data, which demonstrated elevated rates of the condition in the field for vehicles with this update.

Afterward, GM’s Open Investigation Review board reviewed the investigation June 6, and the GM’s Safety and Field Action Decision Authority ultimately decided further action was necessary and issued a safety recall for these vehicles on June 7.

GM notified dealers of this safety recall June 14 and the National Highway Traffic Safety Administration June 20. Owners will receive recall details and dates will available.

The Solution

According to an internal communication, GM will notify drivers, while dealers will reprogram the Vehicle Interface Control Module module at no cost to the cars’ owners. A notification schedule has not yet been provided, but customers who own this vehicle will be notified by mail or can check their Vehicle Identification Number on GM’s website. Owners who want further information can contact Chevrolet customer service at (800)-222-1020. They can also call the NHTSA’s Vehicle Safety Hotline at (888)-327-4236.

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.
