Chevrolet Malibu, Malibu Maxx: Brakes

Affects Chevrolet Malibu, Malibu Maxx · 2004 — about 5K vehicles.

The hazard

On certain vehicles, the Electronic Control Unit (ECU) may calculate a higher than actual vehicle speed because of an erratic rear-wheel speed sensor signal, and cause ABS activation where it is not needed or needed ABS activation to be extended during braking as the vehicle speed drops to about 5km/h. A four-wheel ABS activation could occur for a maximum of 1.25 seconds on a level surface or for up to 2.5 seconds if the vehicle is on a grade, resulting in increased stopping distances of up to 3.4m. Correction: Dealers will reprogram the ABS controller.
