General Motors is recalling 67,380 electric vehicles over a brake software defect. According to GM's filing with NHTSA, software in the brake system control module may misread wheel movement and cause a temporary loss of braking at low speeds, The BRAKE Report says.
The problem can happen when the brakes are lightly applied during a sharp turn and the car hits a bump or dip, such as at the end of a driveway. Normal braking returns on the next press. Only vehicles with performance all-wheel drive are affected: 2023-2027 Cadillac Lyriq, 2025-2026 Celestiq, 2026-2027 Vistiq and 2024-2027 Chevrolet Blazer EV.
The issue surfaced in April after a 2024 Lyriq hit a garage at low speed, Electrek reports. GM found 24 field complaints, including 20 minor crashes, two with alleged minor injuries. The fix is a free software update over the air or at a dealer, and owner letters are expected to go out on December 14. The NHTSA campaign number is 26V717.
