General Motors recalled 67,380 of its electric vehicles over a software defect that can briefly stop braking while the car is moving, which is roughly the last thing anyone wants from the pedal on the left.
The culprit is the brake system control module, or BSCM. Under a specific set of conditions, the module's slip calculation can misread wheel movement. The scenario goes like this: a driver lightly taps the brake pedal mid-corner, the car rolls over a bump, and the software misreads actual wheel speed. The result can be a temporary loss of braking.
Only performance all-wheel-drive versions are affected. The recall covers certain 2023 through 2027 Cadillac Lyriq, 2025 through 2026 Cadillac Celestiq, 2026 through 2027 Cadillac Vistiq, and 2024 through 2027 Chevrolet Blazer EV models.
The chain of events started with a 2024 Cadillac Lyriq that hit a garage at low speed. On April 10, 2026, a GM tech expert flagged it through the automaker's Speak Up for Safety program. Internal testing reproduced the glitch, which GM says resembles a 2024 recall in which some Lyriq anti-lock braking systems released brake pressure without warning. GM says the current software update addresses both problems.
In paperwork submitted to the NHTSA, GM logged 24 field complaints tied to the issue, received between Feb. 24, 2024, and June 11, 2026. Those break down into 20 minor accidents and two claims of minor injury.
The remedy is a BSCM software update, delivered either over the air or at a dealer, free of charge. GM says it has already baked software corrections into assembly over recent months. One asterisk: the automaker has not yet released the update for 2023 and 2024 Lyriq models, so those owners wait.
Owner notification letters are due to reach mailboxes December 14, 2026. GM's recall number is N262570900, and the NHTSA campaign number is 26V717. For a company leaning hard into EVs, a brake software recall that only hits the performance AWD cars is not the headline Cadillac wanted.
