Cadillac Lyriq Gets a Second Brake Software Recall — Now 67,380 GM EVs Are Included
A brake-module software error can briefly cut braking in low-speed turns over a bump. For Lyriq owners, it's the second brake fix since 2024.
General Motors is recalling 67,380 electric SUVs because a software error in the brake control module can briefly cut braking at low speed. The campaign covers all-wheel-drive Cadillac Lyriqs from 2023 to 2027, the 2026–2027 Cadillac Vistiq, the 2025–2026 Celestiq, and Chevrolet Blazer EV SS and police (PPV) models from 2024 to 2027.
For many Lyriq owners, it's the second brake-software recall in just over two years, and GM's own filing says the first fix didn't cover this scenario. The Lyriq is the volume model of the brand's five-strong EV range (how Cadillac’s electric lineup compares on price and range), so it carries most of this campaign.
What goes wrong
According to GM's report to the National Highway Traffic Safety Administration, the fault needs a specific sequence. The driver brakes lightly at low speed in a sharp turn, then a wheel hits a bump or dip, such as the lip at the end of a driveway. That jolt makes the system release and reapply the brakes for a moment, and the software then miscalculates wheel slip.
The result is a temporary loss of braking. GM says normal braking returns on the next press of the pedal. The automaker counts 24 field complaints between February 2024 and June 2026, including 20 minor crashes; two of them involved alleged minor injuries.
The Lyriq accounts for 44,585 of the recalled vehicles, the Vistiq for 18,802, the Blazer EV for 3,911, and the hand-built Celestiq for 82. Rear-wheel-drive Lyriqs and other Blazer EV trims are not included.
A repeat problem for the Lyriq
In August 2024, GM recalled 21,469 all-wheel-drive 2023–2024 Lyriqs (campaign 24V589) because overly sensitive anti-lock braking below 25 mph could keep releasing brake pressure. That remedy was also a software update sent over the air.
The new case started in April 2026, when a GM technical expert filed an internal safety report after a 2024 Lyriq that already had the 24V589 update struck a garage at low speed. An investigation opened in August confirmed the condition in testing and found the earlier fix hadn't addressed it. GM's safety committee approved the new recall on October 22.
What owners need to do
The remedy is new brake-module software that corrects the slip calculation. Owners of OTA-capable vehicles who have accepted GM's connected-service terms can receive it remotely; everyone else can have a GM dealer install it at no cost. GM hasn't said what share of affected owners have opted in to over-the-air updates.
That share matters. When Rivian pushed a software fix for its backup-camera recall, the company said it had already reached more than 95% of affected vehicles. GM's filing gives no comparable figure, and no interim warning letter is planned before the official notices.
Dealers were notified on October 29, and VINs can already be checked on NHTSA's recall lookup under campaign 26V717 (GM number N262570900). Owner letters are due to start going out on December 14 in phases. GM changed the software on the production line between August and October 2026, with the 2027 Vistiq the last to switch on October 21.
Two dozen complaints across more than 67,000 vehicles is a small number, and the scenario is narrow. But as our guide to reading recalls argues, the defect matters more than the headcount, and a brake that lets go in a driveway turn is worth a VIN check today.
