General Motors is recalling 67,380 vehicles due to a software defect that causes temporary loss of braking ability under specific conditions. The recall covers Chevrolet Blazer EVs and Cadillac Lyriqs, Vistiqs, and Celestiqs.
According to the NHTSA recall report, GM is aware of 20 minor accidents caused by the fault, two resulting in minor injuries. The condition occurs only at low speeds.
Cadillac Lyriqs account for the majority of affected vehicles, with 22,819 2024 models, 11,926 2025 models, 9,322 2026 models, 474 2023 models, and 44 2027 models included. The recall also covers 13,627 2026 Vistiqs and 5,175 2027 Vistiqs, plus 51 2025 Celestiqs and 31 2026 Celestiqs. For Chevrolet, only Blazer EV models are affected: 2,012 2025 models, 1,314 2026 models, 562 2024 models, and 23 2027 models. Two-wheel-drive Lyriqs and Blazer EV trims other than SS and Police Pursuit Vehicles are not included.
The braking loss occurs when brakes are lightly applied at low speeds during sharp turns while encountering a bump or depression, such as at the end of a driveway. This causes the software's slip calculation to misinterpret wheel movement and temporarily release braking. The issue affects only vehicles equipped with performance all-wheel drive (pAWD, RPO X0E). Normal brake function returns on the next brake press.
GM will deploy an over-the-air update for owners who have opted into those services. Owners without over-the-air capability must visit dealerships to download the software update. Owner notification is estimated to begin December 14. VINs are searchable on NHTSA's website.
This recall follows a 2024 recall of 21,469 all-wheel-drive Lyriqs for a similar issue. GM found that vehicles built with software changes from that previous recall remain susceptible and require the latest update.
