NHTSA Complaint #11316784 — 2008 MERCURY MOUNTAINEER

AT 28000 MILES THE TRANSMISSION STARTED SHIFTING ERRATIC, THE DEALER REPROGRAMMED THE ECM AND COVERED UP THE PROBLEM UNTIL THE WARRANT ENDED AND THE BATTERY FAILED AT WHICH TIME THE CAR REVERTED BACK TO DEFAULT AND CONTINUED TO BUCK AND JERK UNTIL THE CAR REACHED HIGHWAY SPEED. THIS CONTINUED UNTIL THE TRANSMISSION FINALLY FAILED DURING OPERATION ON THE HIGHWAY ON 3/5/20. THE ABS MODULE JUST FAILED DURING LOW SPEED OPERATION FOR NO APPARENT REASON. ALSO THE CAR INDICATED THAT THERE IS AN ELECTRICAL PROBLEM EVEN THOUGH ALL ELECTRICAL COMPONENTS ARE IN GOOD OPERATIONAL CONDITION. THIS ERROR COMES AND GOES CONSTANTLY AT ANY GIVEN TIME.
