This sensor problem also affects small numbers of Cadillac, Buick, Chevy models.
General Motors has issued an immediate stop-delivery order to some cars in its dealership network due to a new problem with the Chevrolet Corvette. This problem could affect a variety of other GM vehicles and SUVs, however it is not limited to the Corvette. The Corvette Action Center contains information about a potential problem with the brake system. A spokesperson for Chevrolet confirmed this to Motor1.com.
It’s not a mechanical problem. It is a sensor connection to the electronic brake booster system. The connection could have material that might interrupt the signal and cause communication problems between the brake booster system and the sensor. This could result in a loss in the brake booster system. The driver would then need to apply more force to slow down the vehicle.
The problem is sensor-related and affects some models of other GM vehicles. GM has recalled 3,317 models, including:
2020 Cadillac CT4, CT5, XT4
2020 Chevrolet Corvette
2021 Chevrolet Trailblazer
2020-2021 Buick Encore GX
It is not known what the nature of this foreign material is. The Corvette Action Center states that the solution is to replace the electronic brake booster module. However, this fix appears to not be in place yet. Drivers will be notified if the brake booster fails and given a message. Additional braking force may be required to stop a car that is moving. Electronically, the vehicle’s top speed could be limited.
Chevrolet has informed NHTSA about this voluntary recall. However, it is not yet on the NHTSA’s website. Safety Recall A202307260 will be the name of the recall when it goes live. GM also sent a list to dealers of the affected vehicles.
