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.

Chevrolet Corvette Vehicles Recalled for Faulty Hood Latch Software

Pleasanton, CA – August 18, 2020 – General Motors (NYSE:GM) has recalled 7,071 Chevrolet Corvette vehicles whose controls fail to prevent them from developing high speeds despite an unlatched front trunk.

The trunk may then open while driving, increasing the risk of a crash. The recall includes 2020 Chevrolet Corvette vehicles.

Recall summary  

Due to the lack of safety controls, these vehicles can develop high speeds despite having the front trunk unlatched. 

The cause is multifold. First, thanks to a design flaw, drivers can accidentally press the front trunk release button on their key fob.

Second, the cars’ internal controls fail to limit the speed  – allowing the vehicle to reach up to 82 miles-per-hour (mph) – despite detecting that the trunk is not securely closed.

Drivers will still receive audible and visual alerts telling them that the trunk is open.

What happens when the driver speeds up?

As the car reaches a higher speed, air resistance may force open the unlatched hood, blocking the driver’s front view.

Risks 

Not being able to see in front of the vehicle creates a  very high risk of a crash. The driver may not see traffic down the road and hit a vehicle from behind.

To prevent that from happening, drivers should pay attention to their warning system. When the hood is not properly latched, the driver will receive two different types of warnings.

They will first see an icon indicating an open hood on the instrument panel and hear a chime. Once the vehicle is put in drive and moves faster than 3 mph, the chime sounds repeatedly.

In spite of the warnings, the vehicle can be driven up to 82 mph with the hood unlatched. As the driver speeds up, air resistance may force open the unlatched hood.

The repair

GM’s upcoming software update will limit the affected vehicle’s speed to 26 mph when the hood is not latched.

The manufacturer is also going to re-design both the key fob and  the “door trim switch and release button” inside the hood to reduce the risk of a driver inadvertently opening the hood with the fob.

The repair is expected to begin October 3, and is free of charge.

Chevrolet Corvette Vehicles Recalled for Faulty Trunk Release Button

Pleasanton, CA – August 6 2020 – General Motors (NYSE:GM) has recalled 5,141 Corvette vehicles with trunk release buttons that are not working correctly.

When the vehicle is shut off for ten minutes or longer, the release button inside the front trunk compartment will not open the trunk. The recall includes:

  • 2020 Chevrolet Corvette

Recall summary  

On July 30, General Motors determined that certain Corvette models should be recalled to repair the front trunk compartment release button. The button is installed so that someone inside the front trunk can open the trunk lid. 

Risks 

If a person – especially a small child – climbs inside the trunk and shuts the lid, he or she might not be able to get out and is at risk of injury from a lack of oxygen, or extreme heat or cold while in the trunk. It’s important to monitor children who are near cars, or sitting in a parked car without a seat belt in place.

The repair

The dealer will install a software update, so that the release button works correctly. The repair should take 45 minutes, depending on the dealer’s service department schedule. Owners have been notified of the recall, which will begin on September 21. The repair is free of charge.

Chevrolet Silverado Pickup Trucks Recalled for Faulty ABS Indicator Light

Pleasanton, CA – July 17, 2020 – General Motors (NYSE:GM) has recalled 12,200 Chevy Silverado trucks that may fail to indicate to the driver that there is a problem with the car’s anti-lock braking system (ABS), increasing the risk of  a crash. The recall includes:

  • 2019-2020 Chevrolet 4500HD Silverado Medium Duty trucks
  • 2019-2020 Chevrolet 5500HD Silverado Medium Duty trucks
  • 2019-2020 Chevrolet 6500HD Silverado Medium Duty trucks

Recall summary  

On May 29, General Motors decided that certain 2019-2020 Chevrolet   Medium Duty 4500HD/5500HD/6500HD trucks do not comply with a federal regulation requiring the ABS light to illuminate during certain kinds of malfunctions.

Vehicles use several control modules to operate many aspects of the car. GM houses many of these modules together in a grouping called the Body Control Module (BCM), which coordinates many functions in the vehicle, including as the speedometer, the instrumentation panel and the chime warnings.

Another module, called the Electronic Brake Control Module (EBCM), reads sensors in the braking system, and uses that information to activate the ABS as needed for sudden braking, stability or traction control. These two systems need to communicate for the safety of the driver.

In the recalled vehicles, the ABS light fails to illuminate when the BCM can’t communicate with the EBCM. This means that the driver will not be notified when there is a problem with the ABS.

Risks 

It is important for drivers to know if there is a problem with the anti-lock brakes. Driving without the ABS, particularly in bad weather, can be dangerous because the vehicle may not handle braking on slippery surfaces the way it is supposed to.

When a vehicle skids, the tires lose traction with the ground and the driver can no longer steer, increasing the risk of a crash.

The repair

The affected trucks need a software update for the BCM. The update itself should take approximately 35 minutes, but GM advises owners in its owner notification letter that it may take longer “because of service scheduling requirements.”

The repair is available now and is free of charge.

Excess glue caused problems in GM trucks

Laguna Hills, CA – Dec. 20, 2019 – General Motors LLC is recalling certain 2019-2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. The B+ battery positive cable rings may have an excess of glue, increasing the likelihood of an intermittent electrical connection

The potential number of vehicles affected is estimated at 350,371.

The Defect

While driving the vehicle, the glue may soften so that the nut that attaches the battery cable to the alternator loosens, causing an intermittent electrical connection. A bad connection could cause the vehicle stall and also cause arcing, which could generate enough heat to start a fire. The defect was caused by an excess of glue that should have been removed from around the B+ battery cable rings during the supplier’s assembly process. The excess glue resulted in glue contamination.

Timeline of Events

General Motors’ Canadian Brand Quality Manage found a case where a 2019 GMC Sierra stalled because it was missing the nut that secures the B+ cable to the alternator stud. On August 20, 2019, the Brand Quality Manager submitted a report to General Motors’ Speak Up For Safety (SUFS) program. GM opened an investigation on September 10, 2019. The investigation found warranty reports of related field incidents. Between September and November, GM experts analyzed parts to determine the cause of the defect and conducted a torque-curve study. Field data analysis was completed November 25, 2019, finding one case of a related fire.

On December 5, 2019, General Motors’ Safety and Field Action Decision Authority decided to conduct a safety recall.

The Solution

Owners of affected vehicles will be notified and told to take their vehicles to a certified General Motors dealer for repairs, free of charge. Dealers will use a black light to inspect for glue and other contaminants at the B+ cable attachment alternator. Dealers may clean the connection and then reattach the B+ cable connection. If any damage has occurred to the alternator, cable or nut will replace the damaged parts. Secondary black light inspection has been implemented in production to catch the defect moving forward. Secondary inspections began November 14, 2019 at General Motors’ Fort Wayne plant and November 22, 2019 at their Silao plant.

Dealers will be notified of the recall beginning on December 12, 2019, while owners will be notified on January 27, 2020.

General Motors trucks recalled for a software error

Laguna Hills, CA – Dec. 20, 2019 – General Motors LLC is recalling certain 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 vehicles. The Electronic Brake Control Module (EBCM) may have a software error that could disable the Electronic Stability Control (ESC) and Antilock Brake System (ABS).

The potential number of vehicles affected is estimated at 463,995.

The Defect

The affected vehicles have a software defect in the EBCM that will disable the ESC and ABS for a single ignition cycle. In situations where the ABS and ESC are disabled, the vehicle diagnostic’s telltale lamps won’t light up, leaving the driver unaware of the problem. Driving without knowledge of a defective ABS or ESC may increase the risk of a crash. In addition, the lack of warning of a defect puts the vehicles out of compliance with S5.3 of Federal Motor Vehicle Safety Standard 126 and S5.1 of Federal Motor Vehicle Safety Standard 135.

According to General Motors, an estimated one percent of the total vehicles for each model are affected.

Timeline of Events

On November 15, 2019, General Motors’ EBCM supplier, ZF TRW, informed the company that they had found a software error while investigating a related product. On December 5, 2019, General Motors’ Safety and Field Decision Authority decided to call for a noncompliance recall.

The Solution

General Motors will provide dealers with a list of affected vehicles through GM GlobalConnect Recall Reports. General Motors dealers are expected to reflash all affected EBCMs, updating the software and correcting the problem. Moving forward, the software error has been corrected for the 2020 model year.

Because all affected vehicles are the current model and under warranty, General Motors will not have to provide reimbursements. Owners can check to see if their vehicle is being recalled by searching their VIN number at www.vinrcl.safercar.gov/vin/. In some cases, courtesy transportation may be provided to affected drivers. Dealers will be notified of the recall December 12, 2019. GM will begin notifying individual owners January 27, 2020.

GM Recalls Pickup Trucks Due to Seat Belt Fire Fears

Laguna Hills, CA – Nov. 21, 2019 – Well over a half-million pickup trucks manufactured by General Motors LLC are poised to be pulled from the marketplace over safety concerns related to the front seat belt pretensioners. When passengers strap themselves in, a hot gas may emit from pretensioner bracket opening. This could cause a fire within the interior of the vehicle. The potentially compromised models in question include the Chevrolet Silverado and GMC Sierra.

Although GM has yet to announce when motorists will be officially notified of this safety issue by mail, the automaker intends to send mailers alerting registered owners shortly. Recipients are urged to have their cars examined by an area dealership so this problem can be resolved, if one exists. The repair comes at no charge.

The Defect

According to documents submitted to and distributed by the National Highway Traffic Safety Administration, GM is recalling approximately 556,399 pickup trucks nationwide whose seat belt pretensioners – both on the driver and passenger side of the car – may be compromised. Upon the belt’s deployment from the assembly, a flammable gas may emanate out of the bracket aperture. Such a scenario may lead to a fire. All the suspect vehicles have carpet floor mats, which are not fire retardant. Those with vinyl floor coverings are not in any danger.

The specific automobiles included in the GM seat belt fire recall are the following:

  • 2019-2020 Chevrolet Silverado 1500
  • 2020 Chevrolet Silverado 2500
  • 2020 Chevrolet Silverado 3500
  • 2019-2020 GMC Sierra 1500
  • 2020 GMC Sierra 2500
  • 2020 GMC Sierra 3500

Chevrolet Silverados represent the lion’s share of the GM seat belt fire recall at 355,878, based upon NHTSA records and estimates.

Timeline of Events

This issue first came to GM’s attention July 25, when corporate headquarters was briefed about a fire occurring within the cab of a GM-manufactured pickup truck. Internal fire investigators participated in the inquiry as well and determined approximately five days later that the problem may be linked to a similar event that involved the same make and model.

GM and the internal fire experts referred the case to GM’s technical center for follow-up analysis and a more in-depth breakdown as to the nature and cause of the conflagration and how best to resolve it. This subsequent investigation took place in September.

In mid-October, those leading the inquiry determined the most likely cause was a hot gas that vented from the pretensioner opening, which subsequently ignited carpet fibers found on the floor. These findings were then submitted to GM open investigation review board Nov. 4. Three days later, the automaker decided a safety recall was appropriate. No known crashes, deaths or injuries have been reported as a result of this seat belt glitch.

The Solution

While General Motors dealers have since been notified about this safety alert, motorists soon will be, according to the automaker’s  records. There’s no official date as of yet, but GM expects mailers being distributed sent out in the first or second week of December. Those informed are asked to bring their automobile to a local dealer. If deemed necessary after inspecting the suspect seat belt unit, the pretensioner aperture will be closed off, thus stopping the gas’s outflow.

GM Recalls Numerous Vehicles Due to Electronic Stability Control Malfunction

Laguna Hills, CA. – November 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.

Affected vehicles include:

  • 2015 – 2020 Chevrolet Suburban
  • 2015 – 2020 Tahoe
  • 2015 -2020 Yukon
  • 2014 – 2018 Chevrolet Silverado 1500
  • 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.

GM Expands Prior Recall on Chevrolet Trax Vehicles

Laguna Hills, CA – September 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.

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.
