2010 Mercury Mountaineer QuestionsI had a message today I have never seen before. (1 answer)
The message came on while going down the highway. I had filled up the day before. The message was "Check fuel fill inlet". I check to see if it was plugged but it looked normal. What should I do?
My key is stuck in the ignition. The wheels are straight and I have shifted through the gears back and forth to see if it would release the key. The vehicle appears to be shifted in park but the key wont turn all to the off position.
Turn on AC or defrost, strange noise, dies, smells hot. Restarts when AC turned off.

Ford has recalled certain 2010 model year Ford Explorer, Explorer Sport Trac, Fusion, and Fusion Hybrid vehicles along with Mercury Mountaineer, Milan, and Milan Hybrid vehicles for an issue with the front seat backs equipped with manual recliner mechanisms. In the event of a crash, the seat back and head restraint may move rearward, increasing the risk of injury. This is due to incorrect specification in the design of the gear plate teeth on the seat back recliner. Dealers will replace the manual recliners free of charge.
