- A software issue could cause a temporary loss of braking power at low speeds.
- GM will provide a free software update, but the company has not yet released it for some older Lyriq models.
General Motors recalled 67,380 electric vehicles due to a software problem that could temporarily affect the braking system, causing the brakes to fail. GM also recalled some Cadillac Lyriq models after their anti-lock braking systems (ABS) unexpectedly released brake pressure. Only vehicles with performance all-wheel drive (AWD) are affected.
The automaker says its current software update addresses both issues. The recall includes the following vehicles:
- 2023-2027 Cadillac Lyriq
- 2025-2026 Cadillac Celestiq
- 2026-2027 Cadillac Vistiq
- 2024-2027 Chevrolet Blazer electric vehicle (EV)
What Happens to the Brakes
The brake system control module may read wheel movement incorrectly under certain conditions. For instance, the computer system could get confused about how fast the wheels are turning. So, if a driver lightly applies the brakes while turning and hits a bump or a dip, the vehicle may not slow down. This problem could increase the risk of a car crash.
Other GM EV Brake Issues
General Motors had a separate, unrelated brake issue before in 2024. GM recalled certain Cadillac Lyriq models because the ABS could initiate without warning. This could prevent the brakes from stopping normally, making it harder for drivers to stop or slow down. General Motors says the current recall will address both issues.
The Fix
GM will provide a free software update to correct the problem. Owners can receive it wirelessly, without needing to take their vehicle to a dealership.
When Can Owners Get the Repair
GM expects to notify owners of affected vehicles by December. The automaker has not released an update for 2023-2024 LYRIQ models.
