Example complaints

Steering: “The road was dry and bare. I felt a right rear skid (? Black ice ). I tried to turn steering wheel to correct the skid and it was locked. It jerked out of my hands, the engine roared and the car flew to the left across the road into a large tree. I had no control over the steering wheel. On impact of the tree, there was no balloon with air bag deployment, only pungent fumes and white flecks. The car was towed and totaled.”

NHTSA complaint #10725032, filed 2015-06, 36,000 miles

Body and structure: “The body side moldings on my vehicle comes loose, and could come off and become airborne, damaging other vehicles. This defect has been noticed on other 2010 Mercury marquis. The dealer has been great, and is ordering a complete set. They cannot tell me if new ones will have the defect or not? I have no complaint with the dealer. I would like to know if ford has corrected the problem with delamination in the new parts.”

NHTSA complaint #10395984, filed 2011-04, 6,000 miles

Electrical system: “Splicing on almost all electrical systems had come apart. Affected were the radio, clock, windows, power seats, lights, door locks, trunk release inside car, low tire monitor warning light stayed on constantly, seat belt warning light stayed on, warning bell for key in ignition stayed on except when car was moving, dome light would not go off whenever you got out of car. Some of these problems were constant and some were intermittent. As a result of the locking problem, our vehicle was stolen, but thankfully found with no damage. …”

NHTSA complaint #10627951, filed 2014-08, 28,000 miles

Vehicle speed control: “I was pulling into a parking space and had almost come to a stop when the vehicle suddenly lurched forward & hit a (vacant) store front. I feel the vehicle accel- erated on it's own as I was applying the brake at the time, my foot did not slip off of the brake. The vehicle is equipped with drive by wire or, no cable is attached to the throttle body from the accelerator. The dealer repaired the front end of the vehicle and extensively examined the throttle system. No apparent cause was determined and they told us it may never happen again. …”
