NHTSA Complaint #11545144 — 2015 FORD F-350

While driving on Louisiana’s poorly maintained I20 at @70 mph, we hit a bump & our 2015 F350 began violently shaking. We almost lost control, but managed to shift from left lane to shoulder in heavy traffic. Inspected tires & saw nothing amiss. Continued on trip back to TX & it occurred 2 more times whenever we hit a bump. Freaked us out & we were terrified each time we hit a bump, but drove under the posted speed limit & made it the rest of the way home without incident. Called our Ford Dealer 1st thing Tuesday morning Sep 5th & were told they could not schedule us for an appointment til Sep 18th!! Located a mechanic who was familiar with this “death wobble” and he had parts ordered & stabilizer bar installed on Sep 13th. Have not driven in LA yet to confirm this fixed problem but mechanic has a Ford that did same thing & it fixed his truck.
