Sudden unexpected accleration!!!
This afternoon I started my 2015 Mustang Turbo convertible...as I put it in reverse, the engine sped up to nearly 4000 RPMS, without my foot on the gas pedal. I put down 20 foot long burn marks in the pavement before I could stop the car and shut off the engine. After catching my breath...I kept my foot on the brake pedal and pushed the start button...the engine immediately revved to over 3000 RPM. I immediately hit the stop button. Over the next 15 minutes I tried to start the car 5 or six times and it repeatedly over-revved each time. The tow truck never showed up...so after two hours of waiting...I carefully started the engine and it started normally. I slowly drove the two miles to the local dealer without incidence, where it now sits for a diagnosis.
Has this ever happened to you...unexpected acceleration with touching the gas pedal. I know that some people may mistakenly hit the gas pedal instead of the brake. But this malfunction occurred repeatedly while my foot was on the brake and I started and shut off the engine without putting it into gear.
I should mention that I had replaced the battery two days before. The battery had been out for several days. I had driven 20 miles to the parking lot where the incident occurred without any engine malfunction.
