GM vehicles under federal scrutiny after hundreds of reports
Ars Technica • • business
Key Points:
- The federal government is expanding a safety investigation into over 1.1 million General Motors vehicles due to hundreds of reports of brake failure linked to the brake-by-wire system called eBoost.
- The affected vehicles include GM’s electric models and those built for Honda and Acura, with the issue involving a potential spindle fracture while driving.
- GM claims that critical safety features like antilock brakes, traction control, and stability control remain functional after eBoost failure until the vehicle stops, but NHTSA reports contradict this, citing immediate loss of braking in many cases.
- NHTSA has received 227 incident reports, increasing to 745 when including GM’s data, with 22 crashes resulting in six injuries but no fatalities so far.
- The investigation covers multiple model years (2023-2026) of Cadillac, Chevrolet, Buick, GMC, Cruise, Acura, and Honda vehicles equipped with the eBoost system.
