Idling at a metered ramp I experienced unintended acceleration while in line waiting for my turn at the metered light. The car in front of me rolled forward and I following suit. I did not touch the accelerator but merely released my foot from the brake pedal. The truck surged forward unexpectedly. I was able to apply the brakes before impacting the car in front of me. As I sternly applied the brakes the engine settled down and all systems worked as expected for the remainder of my commute. 5/23/2016 approx. 7:25 am cdt. Sunny and clear weather approx 63 degrees f. "normal" humidity. My daughter is the primary driver of this vehicle and when asked if this has happened to her the answer to my surprise was yes.
Spark plug shot from engine. Has 112500 miles on SUV. Was ice and snow on back road 30 miles from home at 14 degrees. Sounded like engine blowing up. Then load ping sound in motor and lack of power. Engine shut off on idle. Was stuck. Have not serviced yet. Ford needs to fix this issue immediately. This 5. 4 l triton should run for longer than 110,000 miles. My old Dodge would not and did not have any issue and it had 130,000 miles when it was wrecked.
