GM Recalls 67,380 Cadillac and Chevy EVs Over Brake Software That Can Briefly Cut Braking

General Motors is recalling 67,380 electric vehicles because a software defect can cause a temporary loss of braking at low speeds. The company told the National Highway Traffic Safety Administration about the problem on October 29, and the campaign is listed as NHTSA 26V717, with GM’s internal number N262570900. The fix is a software update, delivered over the air where owners have opted in, or installed free at a dealership.

The defect lives in the brake system control module. In a specific sequence — light braking in a tight turn at low speed, combined with a bump or dip in the road — the software can misread wheel movement in its slip calculation and briefly release brake pressure before reapplying it. GM says normal braking returns on the next brake press. Only vehicles with performance all-wheel drive are affected, identified by the RPO X0E production code; for the Blazer EV that means the SS and Police Pursuit trims, while two-wheel-drive Lyriqs are not included.

The recall covers the 2023–2027 Cadillac Lyriq, the 2025–2026 Cadillac Celestiq, the 2026–2027 Cadillac Vistiq, and the 2024–2027 Chevrolet Blazer EV. Lyriqs are the largest group, including 22,819 from model year 2024, 11,926 from 2025, and 9,322 from 2026, plus 13,627 Vistiqs from 2026 and 5,175 from 2027. GM reviewed 24 field complaints from early 2024 through June 2026 and counted 20 minor collisions and two crashes with alleged minor injuries. The investigation began after a 2024 Lyriq struck a garage at low speed, reported through GM’s Speak Up for Safety program in April 2026.

Owners should know this is the second bite at the same problem. GM recalled 21,469 Lyriqs for a similar brake issue in 2024, but later found that vehicles with that earlier software patch were still susceptible to the newly described condition, so they need the latest update too. The corrected software is already in production — on Blazer EVs built from August, Lyriqs from September, and Vistiqs from October — and GM expects to begin mailing owner notification letters on December 14, 2026. Owners can already check their VIN on NHTSA’s website.
