Multiple episodes of severe front end shaking and instability that occurs at highway speeds when driving over minimal bumps or other road imperfections. recently this caused a loss of control when it occurred on a freeway not known to have ice spots at 50 mph. the only way i have been able to disrupt this is to quickly reduce speed to below 40 mph which is also dangerous on the freeway.
On 4/19/19 i misfueled my diesel vehicle. i stopped the process immediately and called ford from the filling station. the ford service center said that i should avoid turning the engine on, or even placing the engine in accessory mode because it would engage the fuel pump and flood the system with gasoline. when the tow truck arrived, it became clear that i could not put the vehicle in neutral to be winched onto the flatbed tow truck without turning on the accessory mode. i called ford for an alternative. ford recommended that i disconnect a cable beneath the truck that would disengage the transmission and allow the truck to move. because i could not figure out how to do this, i had to turn on the accessory to get the truck out of park for towing. this caused about $12,000 in damage to the fuel system. more to the point of this complaint, i later discovered that this procedure is not in the manual for my truck. further, the procedure that is in the manual was not mentioned. it is possible that the ford manual contains a procedure that does not apply to the truck. it is also possible that ford is recommending a procedure that is inherently more dangerous than the procedure in the manual.
While towing at speeds above 55-60 mph the vehicle starts to go through a harmonics type of vibration shaking the entire driver's compartment , steering wheel and dash. this vibration continues regardless if the vehicle speed is increased and doesn't stop until the speed is lowered below 55-60 mph.
Between 60 to 75 mph when hitting certain bumps the steering starts violently shaking and will not stop till slow down to about 25 mph. this started at around 24k and has happened 10+ times. also at 37k sync 3 radio no longer will come on and wiring issues cannot get trailer braking to connect to the truck. lights work fine but always shows trailer disconnected so braking doesn't work. you can also start the truck in neutral and put it in any gear without having your foot on the brake.
Before the v8 gasoline engine reaches some prescribed operating temperature ( before the engine is fully warmed up ), when headed downhill, no low gears function in any mode and the engine experiences sudden unintended acceleration. the truck was purchased new in 2018. the ford company has repeatedly acknowledged the defects, and however claims that all 2018 gasoline powered f250s are designed that way to meet certain standards and therefore everything is fine despite being extremely dangerous in certain circumstances. please contact me for further elaboration with names, dates, and places. thank you [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr
