General Motors is under federal investigation following hundreds of reports involving its eBoost brake-by-wire system, which has been linked to at least 22 crashes.
The National Highway Traffic Safety Administration (NHTSA) has opened an investigation into General Motors vehicles equipped with the eBoost brake-by-wire system after receiving multiple complaints from drivers experiencing brake failures.
The eBoost system, which electronically controls braking rather than using traditional hydraulic mechanisms, is the focus of federal scrutiny. At minimum, 22 crashes have been attributed to malfunctions of this technology, prompting the agency to examine whether the defect poses a safety risk to the public.
Brake-by-wire systems represent an emerging automotive technology designed to improve vehicle control and efficiency. However, the surge in complaints suggests potential reliability issues that could affect thousands of GM owners.
The investigation will examine the frequency of brake failures, the circumstances under which they occur, and whether a pattern exists across specific vehicle models or model years. NHTSA may issue a recall if investigators determine the system poses an unreasonable safety risk.
General Motors has not yet released a formal statement regarding the investigation. The company typically cooperates with federal safety investigations and may provide technical data and analysis to assist the agency's review.
This scrutiny comes as automakers increasingly adopt electronic brake systems as part of broader vehicle electrification efforts. The outcome of this investigation could have implications for how manufacturers design and test these systems before deployment.
Drivers experiencing brake issues with GM vehicles are encouraged to report incidents to NHTSA through its SaferCars.gov database. Complaints can also be filed directly with the manufacturer.
