Lincoln Aviator non-functional cruise control issue persists despite multiple service visits on Lincoln Aviator

Some Lincoln Aviator owners report experiencing persistent issues with non-functional cruise control, despite multiple service visits. Common causes of these malfunctions include failed control modules, sensor issues, and throttle actuation problems. Additionally, throttle position sensor failure can lead to engine overcompensation, resulting in black exhaust from the tailpipe. Some owners have also noted problems with the adaptive cruise control system in specific model years. Diagnostic steps recommended include checking the throttle position sensor, control module, and cruise control switch, as well as inspecting the secondary cruise control switch on the master cylinder. If dealerships have been unable to reproduce the issue, owners are advised to ensure that service providers are aware of the problem and to request thorough diagnostic testing. Effective communication with the service department is crucial, especially regarding the ongoing nature of the problem and any previous interactions with Lincoln engineers.
