Brake Assist Concerns: NHTSA Reportedly Probes 3,322 GM Cadillac Lyriq EVs

The U.S. National Highway Traffic Safety Administration (NHTSA) has reportedly initiated a preliminary investigation into complaints concerning brake assist loss in 3,322 General Motors Company GM Cadillac Lyriq electric vehicles.

The NHTSA disclosed receiving reports indicating a firm brake pedal, coupled with a “Brake System Failure” notification during vehicle start-up or while in motion, according to a report from Reuters.

The probe encompasses models from the 2023 production year, the report added.

GM said the electronic brake control module has an internal spindle that can fracture during an anti-lock braking system (ABS) event, according to the NHTSA preliminary evaluation report, which the report noted.

ABS functions to prevent wheel lock-up and slippage, thereby minimizing accident risks.

Attributed to a preliminary NHTSA assessment, General Motors clarified that the spindle fracture may lead to brake assist loss, speed limitations, and compromised ABS functionality.

General Motors has reportedly devised an over-the-air update to notify drivers in case of spindle fractures.

Price Action: GM shares are trading higher by 0.33% at $43.22 on the last check Monday.
