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.
