GoKawiilNHTSA expands probe into GM eBoost brake system covering 1.1 million vehicles
Federal regulators have broadened a safety investigation into General Motors' eBoost brake-by-wire system after receiving hundreds of complaints. The system, used across more than 1.1 million vehicles including GM EVs and models built for Honda and Acura, can suffer a spindle fracture that some drivers say causes immediate, total loss of braking rather than the gradual degradation GM claims should occur.
GoKawiil's interpretation of the reporting above, not reported fact.
Brake-by-wire systems are becoming standard in new EVs, so unresolved doubts about failure behavior could shake consumer confidence in the technology broadly, not just GM's implementation. With 22 crashes and six injuries already reported, the investigation's outcome could determine whether a large-scale recall becomes necessary, affecting automakers who share GM's platforms like Honda and Acura.
- Over 1.1 million vehicles across GM, Honda, and Acura brands use the affected eBoost brake system.
- NHTSA has logged 745 total incident reports, including 22 crashes and six injuries, though no deaths.
- GM disputes claims of immediate total brake loss, saying backup safety systems should remain active until the vehicle stops.
