GM Recalls Numerous Vehicles Due to Electronic Stability Control Malfunction

Laguna Hills, CA – Nov. 1, 2019 – General Motors recently informed the National Highway Traffic Safety Administration of a recall involving five different vehicle models, all of which share the same defect. The field action includes certain 2015-2020 Chevrolet Suburban, Tahoe and Yukon vehicles, as well as certain 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive.

The Defect

According to the official report regarding this issue filed by GM with the NHTSA, the vehicles involved in the recall contain a defect caused by incorrect axle-ratio calibrations in the vehicles’ electronic-brake control module (EBCM). The flaw can cause the module to incorrectly calculate the speed of a wheel that has a faulted wheel-speed sensor. In specific operating conditions and vehicles, this can trigger the vehicle’s driveline protection system at an inopportune time.

“If a wheel-speed sensor fails in these vehicles, a software error in the vehicle’s EBCM can cause the vehicle’s driveline protection system to activate when (i) the vehicle’s electronic transfer case is set to four-wheel drive or automatic mode, and (ii) the vehicle is driven between the speeds of 41 and 60 MPH,” stated GM’s report on the matter. “If the [system] activates, the driver will experience unintended braking on the wheel on the opposite side of the failed sensor … increasing the risk of a crash.”

Timeline of Events

The first report involving the recall arrived May 21, when a GM dealer submitted a warranty report to the manufacturer involving a 2018 GMC Yukon whose owner reported that, while driving between 40 and 45 MPH, the brakes were involuntarily applied and caused the vehicle to pull leftward. A test of the vehicle confirmed the report, and further investigations revealed all the vehicles which might contain the defect.

“GM and ZF (the EBCM supplier) isolated the condition to certain K2 platform vehicles equipped with 5.3 liter engines, four-wheel drive, and 3.08-ratio rear axles, and to specific operating conditions,”
the chronology report provided by GM explained.

The decision to conduct the recall was made official Oct. 17. 

The Solution

Owners of vehicles involved in the recall will be notified sometime in the near future, although the exact schedule has yet to be set. Authorized dealers will reprogram the EBCM for affected automobiles on behalf of GM, free of charge. Those with further questions may contact Chevrolet customer service at 1 (800) 630-2438, GMC customer service at 1 (800) 462-8782, or the NHTSA hotline at 1 (888) 327-4236.

GM Expands Prior Recall on Chevrolet Trax Vehicles

Laguna Hills, CA – Sep. 23, 2019 – In April of this year, General Motors announced a recall on certain 2017-2019 Chevrolet Trax vehicles, due to the possibility that a joint in one or both of the front lower-control arms had been welded in an improper position. GM recently decided to expand the scope of that recall, as a result of further investigations, so that it now applies to include other Chevrolet Trax vehicles that were built in the period between July 1, 2015 and June 30, 2017.

At the request of the National Highway Traffic Safety Administration, GM is handling the recall as a new field action. However, in practical terms, it counts as a “population extension”—the defect remains the same as the one listed in the prior recall, with no significant differences.

The Defect

The defect is now known to exist in certain 2015-2018 model year Chevrolet Trax vehicles. GM estimates that 93,639 such vehicles have the potential to contain the defect, and that roughly 50 percent among that number do indeed contain it. 

“In some of these vehicles, a joint in one or both front lower-control arms may have been improperly welded,” state details in documents filed by GM with the NHTSA. “Over time and in rare cases, an improperly welded joint can fatigue and break, causing the lower-control arm to partially separate from the vehicle”.

If the lower-control arm does separate from the vehicle, then the front wheel attached to the arm will toe outward, adversely affecting steering and increasing the possibility of a crash.

According to the GM documents, the defect was caused because “the component surfacer that is welded to the bushing housing did not conform to applicable design specifications, and as a consequence, was not properly welded to the bushing housing.”

The manufacturer is not yet aware of any vehicle crashes that are attributable to the defect, but notes that if the lower-control arm were to partially separate, the driver may hear a loud noise, and feel the tire begin to rub against the wheel well.

Timeline of Events

The initial recall, which applied to certain 2017-2019 model year Chevrolet Trax vehicles, was announced in April 2019. At the time of that recall, GM was not aware of any claims relating to the defect in question within vehicles built prior to July 2017.

However, in September 2019, GM’s Safety and Field Action Decision Authority reviewed an analysis of field claims generated following the April recall, which found instances of the defect (some confirmed and some unconfirmed) in vehicles built as early as July 2015. Based on that data, the decision was made to create a new recall that applies to a larger range of Chevrolet Trax vehicles. 

The Solution

The repair for the defect is currently available, and will be done at no cost to the customer. Customers who own a vehicle potentially containing the defect will be notified by mail by GM. Dealers will inspect the left and right front lower-control arms, and, if necessary, replace them free of charge.

There are other methods by which drivers can check if their vehicle is involved in the recall: For example, they may enter their Vehicle Identification Number at the GM Owner Center website or at the NHTSA website in order to find out whether or not their automobile might be affected by the recall. 

GM notes that they corrected the potential for the defect by implementing new actions at their supplier in April 2019, such as amending the specifications for the welding, and introducing standardized inspections before and after the weld operation.

Glass Mix–Up Prompts Recall of GM Vans

Laguna Hills, CA – June 7, 2019 – Over a thousand Chevrolet Express and GMC Savana vehicles with model years 2016 to 2019 produced by General Motors LLC, are due to be recalled as a result of the possible wrong installation of tempered glass in the automobiles’ rear windows. The vans were meant to be installed with laminated glass, which tend to be more resistant to shattering, but instead feature tempered glass. In the event of a serious accident – such as a rollover – the tendency of tempered glass to explode increases the risk of injury. GM intends to send out advisories to owners of these vehicles, urging them to take the automobiles to their nearest GM dealer for a free repair. It’s unclear as of yet when those notifications will begin.

The Defect

According to documentation filed with the National Highway Traffic Safety Administration, General Motors is recalling an estimated 1,159 Chevrolet Express and GMC Savana vans, whose model years range between 2016 and 2019. An internal investigation determined that some of these automobiles may have been installed with tempered glass, described as such because they’re reinforced with heat to strengthen their resilience. While tempered glass has more safety properties than standard glass, laminated glass – the type the vehicles are meant to have – has an extra layer of vinyl, which enables the glass to hold its shape more effectively in the event of a crash. This also helps prevent the potential of ejection from the vehicle should motorists not have their seatbelts on during an accident.

Because the vehicles in question do not comply with Number 226 of the government’s Federal Motor Vehicle Safety Standard, which relates to ejection mitigation, GM has decided to pull the 1,150+ vans from the marketplace so that tempered glass can be swapped out with laminated where necessary.

Timeline of Events

The flaw in question came to the attention of General Motors March 18 of this year, when an engineer for the company happened to notice that both a Chevrolet Express and GMC Savana had rear-quarter windows installed with tempered glass instead of the correct laminated type. The engineer made the company aware of the flaw through its Speak Up For Safety, which was formally launched in 2014 and serves as a “see something say something” outlet for GM employees when something is amiss.

A formal investigation was launched roughly a week after the engineer first spotted the flaw, and concluded May 13. GM’s Field Action Decision Authority determined as a result of the findings that some of the cars in question may indeed fail to comply with the ejection mitigation rule established by NHTSA and recommended a recall.

The Solution

Although GM has not yet determined when notifications will be distributed, it intends to inform owners of 2016-2019 Chevrolet Express and GMC Savana to bring their automobiles back to any GM dealer so the proper glass can be installed. The fix will come at no charge to owners. For more information, visit MotorSafety.org or contact GM’s customer service department at 1-586-596-1733. The recall number is N192218960.

GM Recalls 2017-19 Chevrolet Trax Vehicles For Steering Issues

Laguna Hills, CA – April 26, 2019 – General Motors is recalling certain 2017-2019 Chevrolet Trax vehicles. Improper welding of a joint in one or both of the front lower-control arms may result in the detachment of the arm from the vehicle. This could potentially cause the front wheel to toe outward, impacting the vehicle’s steering and handling and leading to a greater chance of crash. As many as 112,958 vehicles may be affected.

The Defect

According to the National Highway Traffic Safety Administration report on this problem, an improperly welded joint in one or both of the front lower-control arms could fatigue and break, resulting in the vehicle’s lower control arm partially separating from the vehicle. If this were to happen, the front wheel attached to the control arm would toe outward, adversely affecting the vehicle’s steering and potentially causing the tire to rub against the wheel well, increasing the risk of a crash.

Timeline of Events

A GM dealer filed a field product report Nov. 14, 2018 concerning a left front-control arm that partially separated from a 2018 Chevrolet Trax. Based on a visual inspection of photos of the failed control arm, GM found that the weld connecting the arm to the bushing did not match design specifications. In response, GM’s supplier originally stated that the welds on the failed component part and other control arms produced at its facility conformed to design specs.

Following a formal product investigation Jan. 31, 2019, GM’s supplier confirmed on Feb. 28 that the welds on the failed part did not comply with the applicable design specifications, and that the welds were improperly modified because the lower-control arm stampings also did not match specs.

From March through April, the automaker worked with its supplier to identify affected vehicles that may have been manufactured with the defective part and to assess the condition’s impact on vehicle performance. GM engineers at the Milford Proving Grounds conducted drivability testing April 12 on a Chevrolet Trax vehicle with a front lower-control arm that was cut at the affected weld.

GM’s Safety and Field Action Decision Authority consequently decided April 15 to conduct a safety recall. As of that date, only two warranty claims relating to this condition had been reported for cars sold in the U.S., with no evidence of any crashes.   

The Solution

GM has not yet provided a notification schedule for the recall. The automaker will notify owners, and dealers will inspect the left and right front lower-control arms, replacing them as necessary, free of charge.

Owners may contact GM customer service at 1-800-222-1020. GM’s number for this recall is A182202370. Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. The NHTSA Campaign Number for this recall is 19V312000.

GM Recalls 2016-18 Cadillac CTS & ATS, Chevy Camaro and Corvette For Power Steering Issue

 

Laguna Hills, CA – March 28, 2019 – General Motors is recalling certain 2016-2018 Cadillac CTS and 2017 Cadillac ATS, Chevrolet Camaro and Chevrolet Corvette vehicles because the power steering assist system may fail, increasing the risk of a crash. As many as 26,772 vehicles may be affected.

The Defect

According to the National Highway Traffic Safety Administration report on this problem, the affected vehicles may experience a loss of electric power steering assist while driving. This would demand more effort in steering, especially at lower speeds, with a potentially greater risk of a crash.

Timeline of Events

GM launched an investigation Sept. 18, 2018 into loss of power steering assist in the 2017 Chevrolet Camaro. Between September 19 and late October, GM’s safety investigator, with help from engineering experts, analyzed vehicle owner questionnaires, customer complaints, legal claims, and warranty data to assess the number of cases in the field and to identify common root causes.

An intermittent electrical loss within the torque-sensor printed circuit board was found in about 80 percent of the cases reviewed. The same issue was found in two Corvette steering gear assemblies. GM then expanded its investigation, discovering that the Cadillac CTS and ATS were also at risk.

Between November and mid-December, field analysis revealed spikes in warranty rates between June and September 2016, and a three-day window in February 2017. Between mid-December and late January 2019, GM worked with its supplier to identify the problematic circuit boards and VIN numbers of affected vehicles.

Following an open investigation review, GM’s Safety Field Action Decision Authority decided  January 31 to conduct a safety recall.

The Solution

The recall will begin March 2019. GM will notify owners, and dealers will replace the power steering gear assembly, free of charge. Owners will receive a second notice when the remedy becomes available. GM’s number for this recall is N182182760.

Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. The NHTSA Campaign Number for this recall is 19V086000.

GM Recalls GMC Sierra 3500 And Chevrolet Silverado 3500 Trucks For Fueling Issue

 

Laguna Hills, CA – March 27, 2019 – General Motors is recalling certain 2016-2018 GMC Sierra 3500 and Chevrolet Silverado 3500 pickup trucks equipped with gasoline engines and dual fuel tanks. If the fuel level sensor in the front tank becomes stuck in a low-level position, the fuel transfer pump may continue to pump fuel from the rear tank to the front tank even after it is full, causing an overpressure condition in the front tank. As many as 18,574 vehicles may be affected.

The Defect

According to the National Highway Traffic Safety Administration report on this problem, the fuel level sensor in the front tank may stick in a low-level position, allowing the rear tank to overfill the front tank. In rare circumstances, the front fuel tank could expand and contact a moving drive shaft, which could create a hole in the front fuel tank and allow fuel to leak. If this happens in the presence of an ignition source, a fire could occur. Customers may hear a grinding or knocking noise if the overpressurized front fuel tank contacts the moving drive shaft.

Timeline of Events

GM originally recalled certain 2011-15 heavy duty trucks equipped with gas engines and dual fuel tanks for the same issue starting Oct. 12, 2017. Although the automaker saw no indications at that time that the condition existed in similar trucks built after 2015, it began to monitor field data for later model years. GM conducted an initial review April 16, 2018 and a subsequent review Oct. 28.

GM’s Open Investigation Review board looked at potentially relevant new field reports identified through the monitoring process Nov. 28 and decided to open an investigation into applicable 2016-18 trucks.

The investigator reviewed the new field data with GM’s subject matter experts. It was found that the problem may be present in vehicles built before the carmaker began using a new low pressure fuel pump in October 2017, but there was no evidence that the condition existed in vehicles equipped with the new fuel pump. As with the previous recall, the issue was limited to heavy duty trucks with gas engines and the dual-tank option, and the only trucks produced with those options were the 3500 series chassis-cab vehicles.

The Open Investigation Review board reviewed the results of the investigation Jan. 28, 2019. As a result, GM’s Safety & Field Action Decision Authority decided Jan. 31 to launch a safety recall for heavy duty trucks built between 2016 and 2018, before GM began using the new low-pressure fuel pump.

The Solution

The recall began March 5, 2019 when owners were sent an interim notification. A second notification will be issued when the remedy becomes available. Dealers will replace the rear tank fuel pump module free of charge. Dealers will also inspect the front tank and replace if necessary. Courtesy transportation is available for customers whose vehicles are involved in this recall and are within the warranty coverage period. GM’s number for this recall is N182204190.

Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. The NHTSA Campaign Number for this recall is 19V088000.

General Motors LLC Recalls 2019 Cadillac CT6 Vehicles for Turn Signal Defect

 

Laguna Hills, CA – March 25, 2019 – General Motors LLC is recalling certain 2019 Cadillac CT6 vehicles because rotating the steering wheel does not prevent the turn signals from flashing. If the turn signals do not automatically stop, the driver may neglect to turn them off manually, misleading other drivers and pedestrians, which could increase the risk of a crash. Up to five vehicles may be affected by this issue.

The Defect

According to the National Highway Traffic Safety Administration Report on this issue, rotation of the steering wheel will not automatically cancel the turn-signals from flashing after a turn is made. Although this action can still be done manually, the driver may fail to respond when turn signals do not deactivate automatically, leaving the signals flashing for some time afterwards. When this happens, a false turn signal may misinform pedestrians and other drivers, which could potentially lead to an accident or crash.

Timeline of Events

General Motors issued its initial report on this problem Feb. 21, 2019. GM decided that certain 2019 Cadillac CT6 vehicles failed to conform to Federal Motor Vehicle Safety Standard 108, “Lamps, reflective devices, and associated equipment.” The automaker then announced a recall beginning March 11.

The Solution

Cadillac dealers will replace the turn signal switch at no charge. Dealers are to service all vehicles subject to this recall at no cost to customers, regardless of mileage, age of vehicle or ownership, from this time forward.

In addition, all affected vehicles currently in the dealer’s possession that have not yet been sold are also subject to the recall. The vehicles must be inspected and repaired before they are delivered to customers, dealer-traded, released to auction, used for demonstration or any other purpose.

Courtesy transportation is available for U.S. customers whose vehicles are involved in this recall and within the coverage period for the warranty associated with this action.

Owners may contact Cadillac customer service at 1-800-458-8006. The Cadillac number for this recall is N182207090. Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. The NHTSA Campaign Number for this recall is 19V117.

GM Recalls More Than 1,000 Chevy Malibus for Air Bag Defects

 

Detroit – Jan. 31, 2019 – General Motors is recalling certain 2010-2011 Chevrolet Malibu vehicles, due to a potentially dangerous air bag defect. Up to 1,145 units may be affected by this issue.

The Defect

According to the National Highway Traffic Safety Administration Safety Report, in the event of a crash necessitating deployment of the driver frontal air bag, the air bag inflator in these cars may explode due to being overpressurized. If the inflator explodes, sharp metal fragments may strike the driver or other occupants, resulting in serious injury or death.

Timeline of Events

On November 30, 2017, an attorney contacted GM and claimed that on Sept. 22, 2017, the front-driver air bag inflator in a 2011 Chevrolet Malibu ruptured during a crash-related deployment and injured his client.

GM reported the allegation to NHTSA Dec. 6 of the same year in accordance with Standing General Orders 2015-01 and 2015-02.  Between Nov. 30, 2017 and Dec. 13, 2018, GM made multiple attempts to locate and inspect the vehicle to confirm whether or not a rupture had occurred. A GM engineer was permitted to inspect the vehicle and components. Based on that examination, GM determined that the front-driver airbag inflator in the subject vehicle likely overpressurized and ruptured during deployment.

On December 19, 2018, GM presented the inspection photos and the other findings of its preliminary analysis to the NHTSA. On Dec. 20, 2018, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall on the ARC inflators built in the suspect manufacturing lot. At the time of the initial filing, GM was not aware of other rupture allegations involving this ARC inflator in GM vehicles.

The Solution

GM has notified owners of these potentially problematic vehicles, and dealers will replace the front driver air bag module for free. Interim notices informing owners of the safety risk were mailed Feb. 8, 2019. Owners will receive a second notice when the remedy becomes available, which is expected to be in late March 2019. Owners may contact GM customer service at 1-800-522-9559. GM’s number for this recall is N182206630. Owners may also contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. The NHTSA Campaign Number for this recall is 19V-019000.

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.
