SERVICE BRAKES
- The defect
- General Motors LLC (GM) is recalling certain 2020 Chevrolet Corvette and Cadillac CT4, CT5 and XT4, 2021 Chevrolet Trailblazer, and 2020-2021 Buick Encore GX vehicles. Sensor connection contamination in the electronic brake boost system may cause an interruption of communication between the sensor and the brake boost system.
- What it can cause
- If communication with the sensor is interrupted, the electronic brake boost assist could be lost. Extra pedal force will be required to slow and stop the vehicle, increasing the risk of a crash.
- What the dealer does
- GM will notify owners, and dealers will replace the electronic brake boost module, free of charge. The recall began December 9, 2020. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-333-4223, or Buick customer service at 1-800-521-7300. GM's number for this recall is A202307260.
- NHTSA's note
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .
How this campaign compares
At 3,677 vehicles this is a bigger campaign than 72% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2020 to 2021, and the defect was reported to NHTSA in 2020, at or before the oldest model year it covers — as current as a recall gets.
This site holds the complaint record for all 7 model years the campaign names. Their owners have filed 406 complaints with NHTSA, 3 of them before this campaign was filed. 63 of those name the service brakes, the system this recall is about — a count of complaints, not of this defect.
The vehicles on this campaign carry 13 other recalls published here, the newest being: 25V148000 (power train), 22V903000 (exterior lighting), 22V868000 (back over prevention), 21V649000 (seat belts).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by General Motors LLC with NHTSA on September 24, 2020 as campaign 20V588000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
