GM recalls multiple models for faulty airbag warning light

Warren, MI – July 1, 2021 – General Motors (NYSE:GM) has issued a recall for 285,622 cars and SUVs over a concern that the airbag malfunction indicator may fail to warn the driver if there is a problem with the airbag, increasing the risk of an injury in a crash. The models that are part of the recall are:

  • 2021 Buick Envision
  • 2021 Cadillac CT4
  • 2021 Cadillac CT5
  • 2021 Cadillac Escalade
  • 2021 Cadillac Escalade ESV
  • 2021 Chevrolet Tahoe
  • 2021 Chevrolet Corvette 
  • 2021 Chevrolet Suburban
  • 2021 GMC Yukon
  • 2021 GMC Yukon XL

The affected part is the Serial Data Gateway Module (SDM) – a gateway that handles the multiple networks in a vehicle – with part number 13542878. It is not clear if the 2021 Corvette Stingray is part of this recall.

Recall summary

The root of the problem is with the GM SDM Programming; specifically, a software issue that causes the airbag sensor to inconsistently illuminate the airbag malfunction indicator light. As a result, the driver may think his or her airbag is working properly when it is not and this could result in inadequate protection in the event of a collision.

Risks

An airbag is meant to protect the occupant from an upper-body injury and frontal airbags have saved over 50,000 lives in the last 30 years. An airbag that does not deploy in the event of a crash can result in serious injury or even death.

Related complaints

In April 2021, the National Highway Traffic Safety Administration (NHTSA) launched an investigation over reports concerning airbag malfunctions in General Motor vehicles. Some of the models that are part of this recall were also investigated.

Of 15 complaints submitted to the NHTSA, six mentioned serious crashes where the airbags failed to deploy. Some also mentioned that the warning lights came on “every two to three minutes when driving.”

GM has not commented on whether this recall is a consequence of the investigation.

Other GM recalls

Back in December 2020, General Motors was ordered to recall 5.9 million cars with Takata airbags that may rupture when deployed.  

Other Chevrolet and Buick recalls in the recent past include the January 2021 recall for mid-size sedans over a potential suspension issue.

The repair

The software issue can be resolved with an over-the-air (OTA) update at a dealership. Affected customers will be notified on July 19, 2021.

  • 2019-2020 GMC Sierra 1500
  • 2020 GMC Yukon
  • 2020 GMC Yukon XL

Recall summary  

Before being placed in service, tires are “cured,” or given final shape, using a mold and a rubber “bladder.” The tires in question were accidentally cured for longer than necessary, making them prone to rupture and failure.

While the tires are being recalled by GM, they are part of a larger problem with Continental brand tires. This recall expands an earlier GM recall in November 2020 and includes more models that may be equipped with defective tires.

In its turn, Mercedes-Benz has also just announced that it would inspect over 2,500 cars due to the same issue. To read about warning signs that may indicate that the tires are defective, please see the recent article we wrote about that recall.

Risks

The defective tires may suddenly go flat. Additionally, the outer tread – which is the part that touches the road –  could separate from the rest of the tire. Both conditions could cause the driver to lose control of the car and crash.

The repair

GM dealers will inspect and, if necessary,  replace vehicles’ tires for free. Notifications with more information will be sent to owners around April 12.

Recent Chevrolet recalls, GMC recalls

GM recalled nearly 6 million vehicles equipped with potentially dangerous Takata airbags in February. The airbags’ inflators may break apart after a crash and kill or injure the occupants of the car with sharp metal fragments.

The recall spanned several GM brands, including Chevrolet and GMC.

General Motors vehicles recalled for potential fuel leaks

Warren, MI– December 10, 2020 – General Motors (NYSE:GM) has recalled 194,105 vehicles due to missing bolts on the start-stop accumulator end cap. The missing bolts may result in a transmission oil leak, a loss of vehicle power or an engine fire. This General Motors (GM) recall includes:

  • 2018-2019 Chevrolet Cruze sedans
  • 2018-2019 Buick LaCrosse sedans
  • 2018-2020 Chevrolet Equinox SUVs
  • 2018-2020 Chevrolet Traverse SUVs
  • 2018-2020 GMC Terrain SUVs
  • 2018 Chevrolet Malibu sedans
  • 2019-2020 Buick Encore SUVs
  • 2019-2020 Buick Enclave SUVs
  • 2019-2020 Cadillac XT4 SUVs
  • 2019-2020 Chevrolet Blazer SUVs
  • 2019-2020 GMC Acadia SUVs
  • 2020 Cadillac XT6 sedans

Recall summary  

Your vehicle’s transmission is designed to transfer engine power to the driveshaft. The start-stop accumulator shuts down the engine when it is not in use to achieve better fuel economy and cut down on emissions.

Each start-stop transmission accumulator is attached using four bolts. In the case of the recalled vehicles, due to a supplier software error, two of the required bolts are missing

Risks 

Missing bolts can create a number of issues:

  • Transmission oil leak: A leak may damage other engine parts, and driving the vehicle without the proper amount of oil or transmission fluid may damage the engine.
  • Loss of vehicle power: A loss of power may prevent the driver from accelerating into a busy road or onto a highway, increasing the risk of an accident. A power loss may also reduce the driver’s ability to speed up to avoid an accident. Finally, the vehicle may slow down on its own until it comes to a complete stop, increasing the risk of being struck by another vehicle coming up from behind.
  • Increased risk of fire: A fire can injure the vehicle occupants, or cause the driver to lose control and cause an accident. This article explains what you should do if you believe your vehicle is on fire.

The repair

To fix the issue, dealers will need to check the start-stop accumulator end cap and determine if any bolts are missing. If they are, the dealer will replace the end cap at no cost to the owner. GM expects the recall to begin on December 14, 2020.

General Motors recalls SUVs for blocked fuel pump nozzle

Laguna Hills, CA – November 16, 2020 – General Motors (GM) (NYSE: GM) has recalled 2,781 midsize SUVs which may have a blocked fuel pump nozzle that could stall the vehicle. The recall includes:

  • 2020 Buick Enclave
  • 2020 Cadillac XT5 and Cadillac XT6
  • 2020 Chevrolet Traverse
  • 2020 GMC Acadia

and concerns the fuel tank pump module (MODULE – F/TNK F/PMP, #84702674).

Recall summary  

The issue stems from the fuel pump, which supplies the vehicle’s engine with the gasoline it needs to run. A tube inside the fuel pump may be blocked by burrs left over from the manufacturing process. This could keep fuel from getting to the engine, particularly if the gas tank is already running low. If the engine is starved of fuel, the car could unexpectedly stall while driving.

Risks

A car that stalls in moving traffic, especially at high speeds, can get hit from behind as other drivers may not have enough time to react. Even if the driver safely gets to the shoulder, they are still at risk of being hit. This raises the risk of injuries or death for everyone involved.

For information on what to do if your car stalls, please see this article.

The repair

Owners will be notified about the recall by mail starting on November 30. GM will replace the fuel pump module for free, but this service is not yet available. In the meantime, owners who are not comfortable driving their recalled car may be eligible for courtesy transportation through their vehicle’s warranty.

General Motors recalls vehicles for contaminated brake booster

Pleasanton, CA – Sept 24, 2020 – General Motors (GM) (NYSE: GM) has recalled 6 different vehicle models which may have a contaminated component in the braking system. This contamination could disrupt sensor communications to the brake booster, making it harder to stop the vehicle and increasing the risk of a crash. The recall includes:

  • 2020-2021 Buick Encore GX subcompact SUVs
  • 2020 Cadillac CT4 and CT5 luxury sedans
  • 2020 Cadillac XT4 compact SUVs
  • 2020 Chevrolet Corvettes
  • 2021 Chevrolet Trailblazer crossovers

Recall summary  

The recall concerns the brake-by-wire system, which uses an electronic brake booster to help stop the car quickly without depending on how hard the driver presses the brake pedal. 

In June, GM launched an investigation after receiving multiple complaints about the strength of the brakes. They discovered that, due to a factory cleaning issue, the connector between the rotor position sensor and the electronic brake control module had been contaminated.

This contamination can disrupt communication between the two parts and disable the electronic brake booster.

Safety tips

Drivers with a failing brake booster may notice that their brakes are difficult to press. They may also notice an increase in the car’s stopping distance. 

Own one of these affected vehicles? It may be wise to keep an eye on the instrument panel, which will display a warning message if the brake booster fails. If this happens, keep the increased stopping distance in mind as you drive.

The repair

Dealers will replace the vehicles electronic brake control module for free. However, this repair is not yet available, as GM is still working on sourcing enough replacement brake boost modules. The company will notify owners when the repair becomes available.

Is your vehicle part of this recall?

Over 3,000 vehicles are part of this GM recall. To see if your car is one of them, use MotorSafety’s free vehicle lookup tool.

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.

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 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.

GM Recalls Vehicles with Defective Seat Belts

Warren, Mich. – April 30, 2018 – General Motors has recalled more than 8,700 vehicles potentially equipped with defective seat belt assemblies, according to documentation submitted to the National Highway Transportation Safety Administration.

The campaign affects 2018 Buick Regal sedans produced between June 9, 2017, and February 22, 2018. GM suspects that 1 percent of the recalled models actually contain the defective parts.

The defect

Affected vehicles contain rear outboard seats with improperly routed seat belts. Consequently, these safety features may not adequately restrain occupants in the event of an accident, leaving them open to injury.

However, the automaker has yet to receive reports connecting the defective components to any accidents or injuries.

Timeline of events

On January 16, 2018, engineers at the Opel Russelsheim assembly plant in Russelsheim, Germany discovered a 2018 Buick Regal sedan with improperly routed seat belts while conducting post-production testing.

The personnel who identified the defect notified their superiors January 22, 2018, through the Speak Up for Safety program. The GM Safety and Compliance Categorization Team reviewed the matter February 15, 2018, and launched a field monitoring initiative.

Seven days later, GM implemented new production methods at the Opel Russelsheim facility to ensure assembly teams properly routed rear seat belts.

GM engineers at the Milford Proving Ground in Milford, Michigan uncovered another vehicle with the rear seat belt routing issue March 1, 2018. They too filed a SUFS report.

One week later, GM connected with technical stakeholders for Opel, one of its European subsidiaries, and discussed the misrouted seat belts it engineers had found in multiple 2018 Buick Regal sedans.

Opel dealt with the same problem earlier in the year and had issued a voluntary recall to address it. This meeting prompted GM to initiate an internal investigation, which led the GM Safety Field Action Decision Authority to call for an official recall on April 5, 2018.

GM notified dealers of the forthcoming action April 12, 2018.

The solution

The automaker has directed dealers to correct the routing of the outboard rear seat belt assemblies installed in affected vehicles free of charge, according to an NHTSA recall acknowledgement document. GM intends to notify owners June 5, 2018.

GM Recalls Vehicles with Faulty Seat Belts

Warren, Mich. – July 10, 2017 – General Motors has recalled more than 40,000 vehicles possibly equipped with dysfunctional software, according to documentation filed with the National Highway Transportation Safety Administration.

The campaign affects over one dozen models across multiple brands, including:

  • 2014 – 2017 Buick Encore sport utility vehicles
  • 2014 – 2016 Buck Lacrosse sedans
  • 2015 – 2016 Cadillac Escalade sport utility vehicles
  • 2015 – 2016 Cadillac Escalade ESV sport utility vehicles
  • 2014 – 2016 Chevrolet Caprice Police Pursuit sedans
  • 2014 – 2017 Chevrolet Corvette sports cars
  • 2014 – 2017 Chevrolet Silverado 1500 pickups
  • 2015 – 2016 Chevrolet Silverado 2500 pickups
  • 2015 – 2016 Chevrolet Silverado 3500 pickups
  • 2014 – 2016 Chevrolet Spark compacts
  • 2014 – 2016 Chevrolet SS sports sedans
  • 2015 – 2016 Chevrolet Suburban sport utility vehicle
  • 2015 – 2016 Chevrolet Tahoe sport utility vehicle
  • 2015 – 2016 Chevrolet Trax sport utility vehicle
  • 2014 – 2017 GMC Sierra 1500 pickups
  • 2015 – 2017 GMC Sierra 2500 pickups
  • 2015 – 2017 GMC Sierra 3500 pickups
  • 2015 – 2016 GMC Yukon and Yukon XL sport utility vehicles

GM suspects 75 percent of the vehicles named in the recall contain the outdated software.

The defect

Affected vehicles contain sensing and diagnostic module software that may not properly deploy front air bags and seat belt pre-tensioning features in the event of an accident.

This poses serious safety risks to drivers and passengers, as they may be left unprotected during collisions. However, the car company has not reports connecting the defective software to accidents or injuries as yet.

Timeline of events

In September of last year, GM recalled more than 3 million vehicles believed to contain problematic SDM software, according to the NHTSA. Approximately 100 percent of the cars involved in the campaign contained the defect.

GM ordered dealers to update the software in all recalled vehicles free of charge, a process that began that very month. Roughly 2.9 million were eventually serviced.

In April 2017, GM personnel conducted an internal audit, reviewing recall and repair records for recent campaigns.

Auditors discovered three instances in which dealers had failed to update the SDM software on vehicles involved in the September 2016 yet reported that the repairs had been successfully executed.

These findings prompted the auditors to evaluate additional repair records and OnStar diagnostic data for approximately 30,000 vehicles named in the aforementioned campaign.

This data indicated that many more models connected to the campaign, an estimated 41,000, might have never received the SDM software update. On May 18, the auditors filed an internal report via the GM Speak Up program.

The GM Safety Field Action Decision Authority chose to conduct an official safety recall June 30. Dealers received notification July 10.

The solution

GM has once again ordered dealers to update the SDM software in affected models. The automaker has pledged to reimburse owners for the repair, according to documents submitted to the NHTSA.

However, GM has not publicized an official notification date for owners.

GM Recalls Buick Sedan Due to Power Steering Defect

Warren, Mich. – Mar. 24, 2017 – General Motors Co. has recalled more than 2,000 Buick sedans due to a serious power steering defect. The recall impacts LaCrosse models produced between August and November 2016, according to documentation filed with the National Highway Transportation Safety Administration.

The Defect

Affected vehicles include electric power steering connector cables that may not be properly sealed. These unprotected features are vulnerable to corrosion and could fail due to extreme oxidization or the development of high resistance, which can cause melting. This poses a serious risk to drivers, as the sudden loss of power steering can hinder vehicle operation and lead to crashes. No accidents or injuries have been attributed to the defect.

Timeline of Events

GM engineering personnel performed two separate wire-harness assessments at the Detroit-Hamtramck assembly factory on Oct. 8 and Nov. 1, 2016, according to the NHTSA. The evaluations targeted Buick LaCrosse models produced at the facility. The vehicles were found to contain unsealed EPS connectors. GM immediately modified its production workflows to address the mistake. Two day later, one vehicle systems engineer at the plant submitted a report detailing the issue. The automaker immediately launched a formal investigation into the defect Dec. 10, 2016.

Inspectors reviewed the faulty connectors and discovered that the OEM parts provider, Delphi Automotive Systems, had provided cables with badly crimped seals. GM personnel were able to remove the connectors without using tools or extreme force. The Safety Field Action Decision Authority division reviewed the results and called for an official recall Feb. 16.

The Solution

GM has ordered dealers to replace faulty EPS connector seals, free of charge. However, the automaker has yet to release an owner notification period, according to NHTSA records. Affected owners are encouraged to contact Buick customer service should they need more immediate help.
