GM brake-by-wire failures trigger broader federal safety probe
Federal safety investigators have widened a probe into GM vehicles after hundreds of reports of brake failures tied to the company’s brake-by-wire system, eBoost. The issue could affect more than 1.1 million cars, including the Cadillac Lyriq and a range of GM, Honda, and Acura models. NHTSA’s ODI has logged 227 incident reports (745 when GM reports are included), with 22 crashes and 6 injuries reported; GM says essential safety features remain active until a full stop, but investigators warn the failures can lead to immediate loss of braking in some cases. The agency has published a list of affected models and years across several GM brands and its partner vehicles.
