NHTSA Complaint #11564276 — 2014 FORD F-350

•Between my wife and I driving approximately 65-75 mph on 5-6 different occasions, with an initial complaint to Ford on [XXX], on I-17 in AZ and other AZ highways the steering wheel and the whole truck shook violently during a stretch of bumpy road or after hitting a pothole. Slowing down has been the only way to stop the wobbling and shaking which creates a precarious situation with semi-trucks behind as my wife has experienced. •Today [XXX], I experienced this wobble and noticed some of the vehicles behind me thankfully had slowed down. I felt I was going to lose control of the truck and possibly crash as a result. As I was about to exit the [XXX], I slowed down to approximately 50 mph and the shaking stopped so I continued to proceed north. There is a long strip of bumpy pavement south of [XXX] and the shaking occurred that lasted approximately 10 seconds as I was passing the [XXX] exit. •The problem has been addressed on multiple occasions: Sanderson Ford on 8/13/2020 (vibration felt in steering wheel when going over bumps). Sanderson Ford on 10/28/2020 (rattle noise from right front wheel when pulling trailer). Diesel Doctors on 11/11/2021 (for independent suspension check Sanderson Ford on 12/06/2021 (severe vibration felt when going over a bump at 65-75 mph from front of vehicle). *Sanderson Ford on 1/4/2021 (front sway bar came loose from brackets while driving). Sanderson Ford on 3/4/2021 (vehicle pulls right). *In 2021 my family and I were driving from Colorado back to Phoenix and as we were south on [XXX] from the [XXX] exit I heard a loud metal clanging sound. There were no mechanical issues experienced thank God but we took it in to Sanderson Ford very soon afterwards. Within the past 1-1/2 weeks, the Advance Trac (downhill) light illuminated and we made an appointment with a diesel mechanic. After today's episode, I called Sanderson for and am waiting on a call back from them. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
