April 15 – The National Highway Traffic Safety Administration (NHTSA) said Monday it has opened a preliminary review to investigate claims related to the brake failure of 3,322 GM electric vehicles.

GM.N Cadillac Lyriq.

NHTSA said it has received reports of a hard brake pedal, followed by a “Brake System Failure” message when starting or driving. The review covers 2023 vehicles.

GM said the electronic brake control module has an internal shaft that could fail in an event related to the anti-lock braking system (ABS), according to NHTSA’s preliminary evaluation report.

The ABS system prevents the wheels from braking and skidding when activated, reducing the risk of an accident.

As a result of an axle failure, vehicles may lose brake assist, experience speed limitation and ABS lose some functionality, GM said in the NHTSA report.

GM has developed an update that will alert drivers if an axle breaks, says NHTSA.

In response to the brake assist issue, GM told Reuters in an emailed statement that the condition was “extremely rare” and that it had recently conducted two investigations into a similar issue with the 2023 Cadillac Lyriqs.

“The Cadillac Lyriq meets all federal requirements for brake system performance, even with Brake Assist disabled,” GM added.
