Brake problems in GM EVs draw greater federal scrutiny
GM's electric vehicles, including models co-developed with Honda, are under increased scrutiny by the NHTSA due to brake system issues. Over 20 crashes or fires and six injuries have been reported, affecting more than 1 million vehicles. The NHTSA upgraded its investigation to an engineering analysis, the highest level, after receiving reports inconsistent with GM's findings. The eBoost brake-by-wire system, used in several GM and Honda models, is under investigation.
