GM Recalls 67,380 EVs Over Brake Software That Can Cut Braking Power

General Motors is recalling 67,380 electric vehicles — the Cadillac Lyriq, Celestiq and Vistiq along with the Chevrolet Blazer EV — over a software fault in the brake system control module that can temporarily cut braking power at low speed. The recall, filed under NHTSA campaign 26V717, reaches only vehicles fitted with performance all-wheel drive.

What's going wrong

According to the recall notice, the brake system control module (BSCM) can misread wheel movement under certain conditions — for example, if a driver lightly applies the brakes while turning and hits a bump or a dip, the module may get confused about how fast the wheels are turning and the vehicle may not slow down as expected. That brief loss of braking ability increases the risk of a crash.

The campaign also sweeps in a separate, unrelated defect GM flagged earlier: on certain Cadillac Lyriq models, the anti-lock braking system (ABS) could release brake pressure without warning, making it harder to stop or slow the car. GM says the same software update addresses both issues.

Which vehicles are affected

• 2023–2027 Cadillac Lyriq
• 2025–2026 Cadillac Celestiq
• 2026–2027 Cadillac Vistiq
• 2024–2027 Chevrolet Blazer EV

Only vehicles equipped with the performance AWD package are in scope, so not every owner of these models is affected.

The fix

GM will correct the problem with a free software update that owners can receive over the air, without needing to visit a dealership. The company expects to start mailing owner notification letters in December, and notes that it has not yet released the update for 2023–2024 Lyriq models.

Canadian owners can check whether their vehicle is affected by entering the VIN on the NHTSA recall lookup or through their dealer. Cadillac owners can call 1-800-333-4223; Chevrolet owners can call 1-800-222-1020. GM's internal reference for the campaign is N262570900.
