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.

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.

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.
