General Motors issues another round of recalls for brake assist system

Pleasanton, CA – November 25, 2020 – General Motors (NYSE:GM) has recalled 14,620 vehicles that operate with either 5.3L or 6.2L V8 engines. In each case, the  power of the mechanical vacuum pump  – which helps the engine with several key functions, including braking – may decrease. This may negatively affect the brake assist system. The recall includes:

  • 2018  Cadillac Escalade sedans
  • 2018 Chevrolet Silverado 1500 trucks
  • 2018 Chevrolet Tahoe SUVs
  • 2018 GMC Sierra 1500 trucks
  • 2018 GMC Yukon SUVs

Recall summary  

Among other functions, the mechanical vacuum pump provides power to the brake assist system. Due to a design error that was not addressed during a previous recall for the same issue last year, “the output” of the pump can drop over time, making the power brake assist system less effective.

There are several factors that alert the driver to the brake assist issue:

  • The brake pedal may vibrate when the driver applies the brakes
  • Braking requires more effort
  • A ticking sound is emitted from the engine compartment when the brakes are applied
  • The driver may see a “Service Brake” message pop up on the dash

Risks 

If the brake assist is not operating correctly, the driver must press on the brake pedal with more effort and depress it further to be able to stop the vehicle.

This change in braking ability increases the risk of a crash. Drivers may not be able to brake quickly enough to slow or stop the vehicle. GM notes that the problem is more apparent at low speeds when a driver applies soft pressure to the brakes.

The repair

To fix the issue, dealers will need to inspect the Electronic Brake Control Module and reprogram the system. The recall free of charge and began on November 16.

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.

Isuzu and Chevrolet trucks recalled for starter motor cable issue

Pleasanton, CA – September 11 2020 –Isuzu Motors Ltd. (NASDAQ:ISUZY) has recalled 4,352 Isuzu and Chevrolet trucks that were manufactured by a joint venture between the two manufacturers.

A cable that connects the starter motor to the vehicle’s frame may break, making it impossible to start the engine. The cable issue also creates a risk of fire. The recall includes:

  • 2018-2021 Isuzu FTR medium-duty trucks
  • 2018-2021 Chevrolet 6500XD commercial trucks

Recall summary  

When the driver starts the vehicle, an electrical current flows through the cable to the starter motor. Here are the problems generated by a broken cable:

  • If the cable is broken, the electrical current moves through the power steering hose. 
  • When a driver attempts to start the truck repeatedly, the heat from the electrical current may melt and rupture the power steering hose.
  • The ruptured hose may leak power steering fluid onto a hot engine or exhaust surface, creating the risk of a fire. Drivers have reported seeing smoke coming from the engine compartment.

Risks 

A fire in the engine compartment can injure the vehicle occupants. Additionally, if the driver loses control of the vehicle due to a fire, other vehicles, pedestrians, and property may be at risk.

The Federal Emergency Management Agency (FEMA) estimated over 171,000 engine fires annually from 2014 to 2016. 

What to do in the event of a fire?

If you try to start the truck and your vehicle catches fire:

  • Remove the key from the ignition.
  • Get all of the occupants away from the vehicle.
  • Call 911.

The repair

To fix the issue, dealers need to replace the ground cable on affected Isuzu FTR and Chevrolet 6500XD vehicles, and inspect the power steering hose. If the hose is damaged, it will also be replaced. All repairs will be free of charge. The recall  is set to begin on October 16th.

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.
