2014 ford f250 super duty 6.7 diesel. Coming down mountain in Arizona (bumblebee pass) hit small bump. Truck began violently shaking in the death wobble mode. Later I was just driving on the freeway and hit a small bump at 70 mph (75 mph zone), again violent shaking that did not stop until I was driving 50 mph. Since Im leaving on cross country trip soon, I opted to take vehicle to mechanic. It is there now. This is because there is no recall on 2014 ford for this issue and I dont have weeks available to fight with ford. have learned today that this is very common across the county and has been reported to ford motor company but the company is denying their liability to fix this very dangerous issue! My vehicle symptoms are exactly what there have been numerous complaints about. I will be sending the bill to ford.
