NHTSA expands GM brake probe to 12 models, two Honda vehicles
NHTSA expanded its investigation into brake-assist loss in GM vehicles with the eBoost system, now covering 12 GM models (2023-26) and two Honda vehicles (Prologue, Acura ZDX), totaling 1.16 million vehicles. GM identified potential spindle fractures but denies an unreasonable safety risk. NHTSA aims to determine if a recall is needed, with 745 failure reports logged, including 22 crashes. Dealers may face increased service demands if a recall occurs.
