The hazard

On certain vehicles, an electronic fault may create a situation where the cruise control cannot be deactivated. If this occurs and the driver does not apply the brakes or shift the transmission to neutral, the vehicle could maintain speed or accelerate without warning, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the Powertrain Control Module (PCM) software and perform an update as necessary. Note: In the interim, owners are advised not to use the cruise control until the vehicle is repaired.
