NHTSA widens GM brake‑assist probe to 1.16 million vehicles tied to eBoost
TL;DR Summary
NHTSA’s ODI expands its investigation into General Motors’ eBoost braking system to about 1.164 million vehicles built for 2023–2026, including Cadillac Lyriq, Chevrolet Colorado, GMC Canyon, Buick Enclave/Envision, Blazer EV, Equinox EV, Traverse, Acadia, Celestiq/Optiq, plus 2024–2026 Acura ZDX and 2024–2026 Honda Prologue; the agency has logged 745 incidents, 22 crashes/fires and 5 injuries. GM says the issue involves spindle fractures in the eBoost system that can trigger a Brake System alert while ABS/ESC remain functional until the vehicle stops; ODI has moved the probe to an engineering analysis to define its scope.
