GM Recalls 67,380 EVs Over Low-Speed Brake Loss: Cadillac Lyriq, Vistiq, Celestiq and Chevy Blazer EV SS Need a Fix

Picture backing out of a driveway: a slow, sharp turn, a light touch on the brake pedal, and a bump where the driveway meets the street. In some GM electric SUVs, that exact moment can make the brakes let go for a split second. GM has now confirmed the problem and is recalling the vehicles to fix it.

General Motors is recalling 67,380 electric vehicles in the United States because software in the brake system control module can cause a temporary loss of braking at low speeds. The recall covers the 2023-2027 Cadillac Lyriq, 2026-2027 Cadillac Vistiq, 2025-2026 Cadillac Celestiq and 2024-2027 Chevrolet Blazer EV, though only certain versions of the Lyriq and Blazer EV are included. The fix is a free software update, sent over the air or done at a dealer.

Which Models Are Affected?

The Lyriq makes up about two-thirds of the recall. For the Lyriq and the Blazer EV, only vehicles with GM's performance all-wheel drive (pAWD, option code RPO X0E) are involved. On the Blazer EV, that setup is only offered on the SS and the Police Pursuit Vehicle (PPV), so regular Blazer EV LT and RS models are not part of this recall. GM's filing does not list a drivetrain limit for the Vistiq or Celestiq.

By brand, that works out to 44,585 Lyriqs, 18,802 Vistiqs, 82 hand-built Celestiqs and 3,911 Blazer EVs.

What Goes Wrong With the Brakes?

This is not a mechanical failure. The brake hardware is fine. The problem sits in the software that runs the brake system control module (BSCM), the computer that manages braking, ABS and traction control.

According to GM's filing, the problem shows up under a very specific set of conditions. When the brakes are lightly applied at low speed during a sharp turn and the vehicle hits a bump or dip, such as the end of a driveway, the brakes can briefly release and reapply. That can confuse the software's slip calculation, which judges how fast each wheel is turning compared with the road. If the software misreads wheel movement, it can cut brake pressure for a moment.

GM says normal braking returns on the next press of the brake pedal. The issue is tied to how certain vehicles with performance all-wheel drive were set up.

How GM Found the Problem

The recall traces back to a single low-speed crash. On April 10, 2026, a GM technical expert filed a report through the company's internal Speak Up for Safety program after reviewing an incident in which a 2024 Cadillac Lyriq struck a garage at low speed.

That Lyriq already had the software fix from an earlier recall. In August 2024, GM recalled 21,469 Lyriqs from the 2023 and 2024 model years (NHTSA 24V589) because the ABS could activate unexpectedly and release brake pressure. GM's testing reproduced the new condition, and the company concluded it involved a set of circumstances that the 2024 fix did not cover.

• April 10, 2026: Internal safety report filed after the garage crash.
• August 18, 2026: GM opens a formal product investigation.
• October 22, 2026: GM's safety decision board orders a recall.
• October 29, 2026: Recall filed with NHTSA, dealers notified and VINs searchable.
• December 14, 2026: Owner notification letters expected to start.

What Owners Should Do

1. Check your VIN. Enter your 17-digit VIN at nhtsa.gov/recalls. Affected VINs have been searchable since October 29. You can also call the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
2. Accept the over-the-air update. If your vehicle can receive OTA updates and you have accepted GM's connected-services terms, the new brake software can be installed without a dealer visit.
3. Or book a dealer visit. Any owner can have the update done at a Cadillac or Chevrolet dealer. The repair is free.
4. Call GM if you have questions. Cadillac customer service: 1-800-333-4223. Chevrolet customer service: 1-800-222-1020. Mention GM recall number N262570900.
5. Drive with extra margin until it is fixed. Leave extra room in driveways, garages and parking lots, where slow, sharp turns over bumps are most common. If the pedal feels like it lets go, pressing the brake again should restore normal braking, according to GM.

What It Means for US Buyers

GM says the software correction is already in production. The fixed code went into Blazer EV production on August 8, 2026, Lyriq production on September 7, 2026, Vistiq production on October 21, 2026, and 2027 model year Celestiq production. Vehicles built after those dates should not need the update, but the only way to be sure is to check the VIN.

For used-EV shoppers, a Lyriq is the most likely to be on this list, especially a 2024 or 2025 model. Before you buy, run the VIN at nhtsa.gov/recalls and ask the seller or dealer to confirm the brake software update has been done. A dealer selling a used car with an open recall is not always required to fix it first, so it is worth asking.

The bigger story is how the fix arrives. A brake recall that once meant a service appointment can now land in the driveway overnight. That is good news for owners who accept updates. It also means GM's second attempt at this brake software problem has to get it right.
