Overview
- ODI upgraded its preliminary evaluation to an engineering analysis on Monday and broadened the inquiry to about 1,164,820 GM and GM‑built Honda/Acura vehicles equipped with the eBoost system.
- The agency’s combined data include 745 reported incidents, 22 crashes or fires, and several injuries, with no fatalities reported in the documents cited by news outlets.
- GM has told investigators its internal work links failures to fractures in an eBoost spindle and that ABS, traction control, and stability control should remain functional until the vehicle stops.
- ODI says many owner accounts describe an immediate loss of brake assist while braking, which would increase stopping distance and raises a safety concern that is inconsistent with GM’s account.
- The eBoost system is a brake‑by‑wire design introduced in 2019 that replaces a mechanical pedal link with electronic control, and the engineering analysis is the most intensive pre‑recall review that can lead to formal remedies or a recall.
