General Motors is recalling 67,380 electric vehicles. The cause is a software problem that can briefly cut braking at low speeds. The recall covers four models across Cadillac and Chevrolet, and it is the second brake software fix for several of these vehicles in about two years.
Which Vehicles Are Included
The recall covers these model years:
- Cadillac Lyriq: 2023 to 2027 (the largest group, with nearly 23,000 from the 2024 model year alone)
- Cadillac Vistiq: 2026 and 2027
- Cadillac Celestiq: 2025 and 2026 (only about 80 vehicles)
- Chevrolet Blazer EV: 2024 to 2027
Reports on the earlier recall say the problem mainly affects performance all-wheel-drive versions.
What Can Go Wrong
The fault is in the software that runs the brake system control module. In a specific set of conditions, the software can misjudge how much the wheels are slipping. When that happens, the brakes can briefly stop working at low speed.
The earlier recall described one example: braking lightly through a sharp turn while going over a bump or dip. Pressing the brake pedal again can bring braking back. But in a parking lot or a garage, a short delay is still long enough to hit something.
Why GM Opened a Second Recall
GM recalled many of these vehicles in 2024 under campaign 24V589. Then, in April 2026, a 2024 Lyriq that already had that fix struck a garage at low speed. A GM technical expert reported the incident through the company’s internal Speak Up for Safety program, and GM started a new review.
GM has found 24 complaints that may be related. They include 20 minor crashes and two reports of alleged minor injuries.
How the Fix Works
The remedy is a new brake software update, and it covers both the old issue and the new one. Many owners can get it over the air if they accept the update terms in the vehicle. Owners can also have it installed at a GM dealer. Either way, the update is free.
GM decided on the recall on October 22 and notified dealers on October 29. Letters to owners are scheduled to go out starting December 14, 2026.
What Owners Should Do Now
- Enter your 17-digit VIN at NHTSA’s recall lookup (nhtsa.gov/recalls) or on GM’s owner site.
- Accept any pending over-the-air update in your vehicle.
- Until the fix is installed, take low-speed turns in tight spaces slowly and leave extra room in garages and parking structures.
The Bigger Picture
More and more of a modern car’s basic functions run on software, and braking is one of them. Over-the-air updates make fixes faster and easier. This recall also shows that a software fix can have gaps, and that a second look is sometimes needed.
