The U.S. National Highway Traffic Safety Administration (NHTSA) has initiated a preliminary evaluation into reports of brake assist problems affecting 3,322 Cadillac Lyriq electric vehicles from General Motors (GM).
According to the NHTSA, drivers have reported encountering a firm brake pedal and receiving a “Brake System Failure” message either upon startup or while driving. The probe is specifically focused on the 2023 model year vehicles.
GM has attributed the issue to a potential fracture in the electronic brake control module’s internal spindle during an anti-lock braking system (ABS) event. ABS is designed to prevent wheels from locking up and skidding when brakes are applied, thereby enhancing safety and reducing the likelihood of accidents.
As a result of the spindle fracture, affected vehicles may experience a loss of brake assist, speed limitation, and a partial loss of ABS functionality, GM stated in the NHTSA report.
In response to the investigation, GM has prepared an over-the-air update that will notify drivers if the spindle fractures, according to the NHTSA.
The safety agency’s investigation underscores the importance of promptly addressing potential safety concerns in vehicles to ensure the safety of drivers and passengers.
