The National Highway Traffic Safety Administration (NHTSA) is expanding a safety investigation into vehicles manufactured by General Motors (GM) due to reports of brake failures. This issue affects over 1.1 million vehicles, including several electric models and those built for Honda and Acura. The investigation focuses on the brake-by-wire system known as eBoost, which may experience spindle fractures while driving. GM states that in such cases, critical safety features like antilock brakes, traction control, and stability control should remain operational until the vehicle comes to a complete stop. However, NHTSA's Office of Defects Investigation (ODI) has received numerous reports suggesting that failures of the eBoost system lead to an immediate loss of braking, presenting a potential safety hazard. NHTSA has documented 227 incident reports, with the total rising to 745 when including reports made directly to GM. Among these incidents, 22 resulted in crashes, with six injuries reported across five crashes, though there have been no fatalities.
