Vehicle-Specific Recall Note
NHTSA campaign 97V131000 involves the vehicle speed control on certain models. The cruise control and throttle cables are attached to the same throttle valve actuating lever at the throttle housing. A plastic bushing on either cable could break due to environmental influences and vibration, causing the outer cable housing to separate from the bushing. If this occurs during throttle pedal application without cruise control engaged, the outer tube could catch on the broken bushing, potentially causing the throttle valve to remain partially open. This may result in the vehicle not decelerating as expected, increasing the risk of a crash. A VIN-level recall check is required to determine if a specific vehicle is affected or has an unrepaired recall.
Engine Oil Notes
