Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Multiple instances of my car accelerating while in a lower RPM such as at a stop light, drive thru window and parking lots. Especially increased instances when the air conditioning is running. This also causes the car to die completely in some cases. I have to try to pull over somewhere in order to put the car in park and restart it. This issue with the acceleration is increasing in frequency lately. I can count on it to happen every single time I have the air conditioner running and sometimes when it is not. Problem has occurred hundreds of times. It is very dangerous! …”
NHTSA complaint #11229344, filed 2019-07, 111,500 miles“I have experienced a sudden unexpected lunge when backing out of a parking space after placing the vehicle in reverse on several occasions. You can hear the engine RPM increase quickly, then decrease just as quickly when this happens. This typically occurs when the vehicle is placed in reverse and the wheel is being turned and the my foot is on the brake pedal. It has also occurred again when the vehicle is put into drive after going from reverse and the wheel is turned. …”
NHTSA complaint #10403179, filed 2011-05, 83,500 miles“Our 18 year old daughter who has a permit was driving our 2007 monetego one evening with me. When she went to park at a drive inn restaurant under my guidance, she was pulling into a parking space and the car unexpectedly lunged forward. As an inexperienced driver she panicked and took her foot off the brake - endangering the lives of at least 10 people that were eating at the picnic tables outside of the restaurant. Thankfully the car was going at a relatively low speed and the curb stopped its forward motion. …”
NHTSA complaint #10355656, filed 2010-09, 48,000 miles“Engine speed fluctuates suddenly with no operator input (throttle pedal), especially when shifting (automatic) transmission from park to reverse or drive. Causes vehicle to lunge during parking maneuvers. Also requires abnormal braking input in traffic when normally engine braking would suffice. Has been serviced once by a ford dealer (computer was reprogrammed); was not successful.”
NHTSA complaint #10460738, filed 2012-06, 155,000 miles“This vehicle has a serious/scary surging problem when shifting from park to drive, park to reverse, drive to reverse, reverse to drive or when simply maneuvering to park. This problem began a couple of weeks ago and has gotten progressively worse. A web search has shown that this problem is pretty common in this auto but I have yet to see the problem pinpointed. This is a real safety issue.”
