HAVE A 2009 MERCURY MOUNTAINEER WITH 71,000 MILES. IN THE PAST 10 DAYS, HAVE HAD FOUR INCIDENTS WHERE, WHILE DRIVING, THE DRIVER'S SIDE POWER FRONT SEAT HAS SUDDENLY REVERTED TO THE EASY EXIT POSITION. WE BOUGHT THIS CAR USED WITH 22,000 MILES. HAVE HAD THE CAR FOR FOUR YEARS. MY WIFE AND I ARE TALL; HOWEVER, EVEN AT THAT, WHILE DRIVING AT SPEEDS BETWEEN 55-70 (ON TURNPIKES AND MAJOR HIGHWAYS), THIS IS STILL AN ISSUE. TOOK CAR TO A FORD DEALER IN READING, PA - ON A SATURDAY (MAYBE THEY DON'T DO AS MUCH INTENSIVE DIAGNOSTICS ON WEEKENDS?) RECENTLY WHO FOUND NO ISSUES ALTHOUGH THEY INDICATED OTHER MOUNTAINEERS OF THE 2002 OR 2005 MODELS HAD SIMILAR ISSUES AND IT APPEARED TO BE AN PROBLEM WITH THE IGNITION SWITCH. DID NOT GET THE IGNITION REPLACED BUT THE SEAT MOVED AGAIN TODAY WHILE MY WIFE DROVE THE CAR. WILL GO BACK TO THE FORD DEALER DURING THE WEEK TO GET MORE INTENSIVE DIAGNOSTICS. *JS
