Engine Oil Leaking problems of the 2013 Ford F-150

Tl the contact owns a 2013 Ford F-150. While driving various speeds, the front end of the vehicle shook and vibrated and the rear end of the vehicle became unstable and swayed from side to side. The vehicle was taken back to the dealer (werner Hyundai in tallahassee, FL) where it was diagnosed that the leaf springs were faulty and needed to be replaced. The parts were not available and the vehicle was not repaired. Later, while the vehicle was parked, a loud air pressure type noise was heard under the hood. The contact discovered oil had leaked from the engine. The vehicle was towed back to the dealer, but no failures related to an oil leak were found. The manufacturer was not notified of the failure. The VIN was not available. The failure mileage was 92,000.

Multiple times now, my truck will downshift and send the rpms over 4500 this causes the engine to misfire, the engine light will blink and the truck will struggle to maintain its speed and any acceleration is extremely diminished. This is extremely dangerous as I frequently drive on rural 2-lane(one in each direction) highways and find this problem significantly impacts my ability to safely pass slower vehicles. It has failed to accelerate enough times that I cannot depend on the truck to accelerate when I move into oncoming lanes of traffic. At 30,000 miles the engine developed an oil leak. Within a month of having the leak repaired at the dealer, the engine experienced a major misfire event causing the engine light to come on. I returned the vehicle to the dealership for repair. The dealership explained that two ignition coils went bad and required replacement. This caused damage to the spark plugs for which I was charged approx $250 but was able to negotiate it down to $140. Within a month of getting the vehicle back, the vehicle started displaying the misfire symptoms with diminished acceleration and blinking engine light. Very unhappy with this vehicle's performance!.
