Forward Collision Avoidance: Adaptive Cruise Control

Ford Motor Company (Ford) is recalling certain model year 2015 Ford F-150 trucks manufactured March 18, 2014, to August 6, 2015 and equipped with Adaptive Cruise Control (ACC).

What owners wrote

“The clock spring in the steering has failed causing the airbag to no longer work on the driver side. The cruise control turns on and shuts off on its own. Sometimes won’t even let you set it. Volume controls no longer work. Horn no longer works. Steering has a clicking catching sound now when turning. Steering controls no longer light up and none of the buttons work.”

Should you keep driving it?

This page can't tell you that. 0 of 60 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
