GM Recalls 67,380 Cadillac and Chevy EVs Over Brief Loss of Braking
GM is recalling 67,380 Lyriq, Vistiq, Celestiq and Blazer EV models over brake software. See which years are covered, the fix and when owner letters go out.
General Motors is recalling 67,380 electric vehicles from its Cadillac and Chevrolet brands because a software error in the brake system control module can briefly cut braking power, according to a recall report GM filed with the National Highway Traffic Safety Administration. GM estimates that 100% of the recalled vehicles have the defect.
The remedy is a software update for that module. Vehicles that can take over-the-air updates can receive it remotely, while the rest will be updated at a dealership. Owner notification letters are scheduled to start going out Dec. 14.
Which Cadillac and Chevrolet EVs are included
Four models are part of the recall, according to the NHTSA filing as reported by Autoblog:
- 2023-2027 Cadillac Lyriq: 44,585 vehicles
- 2026-2027 Cadillac Vistiq: 18,802 vehicles
- 2024-2027 Chevrolet Blazer EV: 3,911 vehicles
- 2025-2026 Cadillac Celestiq: 82 vehicles
The Lyriq makes up most of the total, followed by the Vistiq. Every model on the list is fully electric.
How the brake software fails
The brake system control module, or BSCM, is the electronic unit that manages how the brakes respond to the pedal. GM’s report describes a narrow set of conditions: the vehicle is creeping along at low speed, turning sharply, and rolls over a bump while the driver is pressing the brake pedal lightly. In that moment the software can misjudge the situation and stop applying braking force.
The loss is temporary. Pressing the pedal again restores braking, according to the filing. GM said the condition raises the risk of a crash.
How GM traced the problem
The investigation began after a technical expert reported that a Cadillac Lyriq had struck a garage at low speed in April. GM engineers then reproduced the brake loss in testing. The test vehicle had already received software changes from an earlier recall, so that earlier fix did not prevent this fault.
A review of field reports turned up 24 complaints that may be related. They include 20 minor crashes and two claims of minor injuries.
What it means for Lyriq, Vistiq, Celestiq and Blazer EV owners
The described failure happens at low speed during tight turns, the kind of driving involved in the garage incident. Owners can check their status before the letters arrive. Recall status for these vehicles has been searchable since Oct. 29: owners can enter their vehicle identification number (VIN) at nhtsa.gov/recalls to see whether the brake software recall applies.
Recall repairs are free. Owners whose vehicles do not receive the update over the air can have it installed at no cost at a franchised Cadillac or Chevrolet dealer. Owners who rely on remote updates will need the vehicle’s over-the-air update settings turned on for the patch to arrive automatically.
GM has also added the corrected software on the production line for specified 2026 and 2027 model-year vehicles, depending on the model. Some newer vehicles built after that change already carry the fix, and a VIN check will show whether a particular vehicle still needs it.
What happens next
GM plans to roll out the recall in phases, with owner notifications beginning Dec. 14, 2026. Vehicles set up for over-the-air updates will get the patch remotely as the campaign proceeds, and the remaining vehicles will be updated by dealers once owners are notified.
