Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Brakes
What's wrong, in plain English: Anything that slows the car down. Treat brake recalls as urgent. Sensor connection contamination in the electronic brake boost system may cause an interruption of communication between the sensor and the brake boost system.
What could happen: 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.
The fix: 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 recal…
