NHTSA Complaint #11513833 — 2019 FORD F-350

Traveling at 60-65 mile per hour on interstate freeway, hit a group of small potholes with left wheels. Truck shook as you would expect at first, then began to shake increasingly more violently in the front end. The shaking increased till the front end was bouncing up and down and shaking left to right. The steering wheel shook left and right. I took my foot off the accelerator and coasted to the shoulder and stopped. My passenger's and my safety were put at risk because the truck was difficult to control and slowing down did not bring the situation under control until we got down to about 20 mph. Fortunately we were in the right lane, so we had quick access to the shoulder. I don't know what component failed, but this behaved as if the steering were repeatedly over-correcting for what it saw as a potential spin-out in alternating direction. After the incident the front tires showed wear marks slightly up the sidewalls (about 1 inch) that suggested they had skidded sideways several times. All tires were properly inflated at the time: 61 pounds front, 80 pounds rear. There were no warning lamps or alerts before or after the incident. The vehicle has not yet been inspected by the dealer. No police or insurance representatives were notified since there was not an accident or injuries.
