The contact owns a 2006 Ford Five Hundred. The contact stated that the vehicle had an unexpected acceleration as the check engine warning light illuminated. The contact was unable to stop the vehicle or place it in reverse when the failure occurred. As a result, the contact crashed into another vehicle. A police report was not filed and there were no injuries reported. Additionally, the contact mentioned that the vehicle failed to accelerate out of first gear. The vehicle was not diagnosed or repaired. The failure mileage was 56,000.
Vehicle surges for no particular reason and shows. A check engine light on (wrench). Control of acceleration is mixed and vehicle either lurches or feels as though transmission is in neutral and rpm's increase without acceleration by driver. Have a scheduled service call with Ford and have been issued a notice from Ford that this issue will be covered.
While running the air conditioner, then either briefly shutting off engine or idling in park or neutral, once the car is shifted into drive gear the engine accelerates on its own, foot break is on. Rpms increase for 3-4 seconds then go back down to normal. The car was unable to lurch forward only because I've had my foot on the break due to my shifting of gears (from park or neutral to drive). The first time this happened I only had the break pedal slightly depressed - car jumped forward - I fully depressed brake pedal to stop. Occurs intermittently but intensity of surge increasing. Yesterday had a much stronger surge in drive-thru, then car stalled. Was able to restart, engine light has remained on since yesterday's incident. Top motor mount damper (round rubber disk) is cracked thru as well, probably due to lurching.
