GM Recalls 67,380 Electric Cadillacs And Chevy Blazer EVs Because A Brake Software Glitch Can Reduce Braking After A Light Tap In A Sharp Turn

General Motors is recalling 67,380 electric vehicles because a software glitch in the brake control module can reduce braking after a light tap on the pedal in a sharp, slow turn. The recall, filed as NHTSA campaign 26V717, covers several models built on GM’s BEV3 platform.

Normal braking returns the moment the driver presses the pedal again. Still, a brake that fades when you need it is not something anyone wants to learn about in a driveway.

Owners can look up their VIN on the National Highway Traffic Safety Administration recall page.

Which Cadillacs And Chevy Blazer EVs Are Included

The Cadillac Lyriq is covered for model years 2023 through 2027, but only when equipped with Performance All Wheel Drive. The Chevrolet Blazer EV is covered in SS and PPV trims, and the Cadillac Vistiq and Celestiq are covered for 2025 through 2027.

Other versions of those models are not part of this recall.

A Light Tap, A Tight Turn, A Bump, Then A Quick Release

GM says the brake control module’s slip calculation was poorly coded and can misread wheel movement. The trouble shows up in a very specific chain of events.

The driver brakes lightly while going through a sharp, low speed turn. The vehicle then crosses a bump, such as the edge of a driveway, and the driver briefly releases and reapplies the brake pedal.

At that moment the module can reduce braking performance. GM reproduced the condition in its own testing, and braking comes back when the pedal is pressed again.

24 Complaints, 20 Minor Accidents And Two Minor Injuries

GM found 24 field complaints filed between February 2024 and June 2026. Among them, the company knows of 20 minor accidents and two reports of minor injuries.

One report involved a 2024 Lyriq that had already received a software update under an earlier recall. According to GM, that vehicle struck a garage at low speed, and the company logged the event on April 10, 2026.

NHTSA opened an investigation in August 2026, and the recall followed.

Why A Software Slip Can Touch Your Brakes

In an electric vehicle, the pedal and the brakes work together with software that blends motor regeneration and the friction brakes. The brake control module watches how fast each wheel is turning so it can manage that blend smoothly and keep a wheel from locking.

When the slip calculation misreads what a wheel is doing, the module can pull back braking when the driver does not expect it. That is the heart of this recall, and it is why the remedy is a code fix rather than a new part.

GM’s filing says the condition was reproduced in internal testing, which is how the company confirmed the cause.

The Fix Is Software, Free, And Can Arrive Over The Air

Dealers will update the brake control module software at no cost to owners. The update also addresses the condition covered by that earlier recall, 24V589.

Owners can also get the update over the air if they accept the applicable terms, and GM says it should take no more than 20 minutes.

What Electric Vehicle Owners Should Do Next

Check your VIN first. If your Lyriq, Blazer EV, Vistiq or Celestiq is on the list, you can either schedule a dealer visit or look for the over the air update in the vehicle’s screen or the owner app.

Do not be shy about asking questions. A dealer can explain which update your vehicle has already received and confirm that the new software is installed when the work is finished.

Until the update is done, adjust a few habits. When you pull into a driveway or garage, go slowly and give yourself extra room. If you feel the pedal give less braking than you expect, press it again firmly.

Keep in mind how narrow the trigger is. It takes a light brake application in a sharp low speed turn, then a bump, then a quick release and reapply, which is a combination most drivers will rarely hit, though the 24 complaints show it does happen.

If you are buying a used electric Cadillac or Chevy, run the VIN before you sign. Software recalls leave no physical trace on the car, and a dealer record or the federal lookup is the only way to confirm the work was done.

If you are not sure whether your update came through already, ask the dealer to print the software level on your service record. It takes a minute, and it gives you proof if questions come up later.

Dealers across the country are used to these software visits, and most can handle them while you wait or during a short appointment.

Modern cars are rolling computers, and that is both the good news and the bad news. A bug can be fixed in a short update, often without leaving home, but a bug can also hide until a very particular sequence of events brings it out.

For owners, the practical advice is simple. Check your VIN, accept the update when it is offered, and keep the paperwork for your records.
