ENGINE, POWER TRAIN, UNKNOWN OR OTHER
SINCE I PURCHASED IN 2009, ENGINE KILLS ANYTIME, MOSTLY WHEN GAS PEDAL NOT PRESSED. PULLING OUT OF PARKING LOTS, SITTING AT RED LIGHTS, OR LETTING OFF GAS ON INTERSTATE, ENGINE JUST KILLS. SOMETIMES FEELS LIKE A JOLT. I HAVE TO PUT THE SHIFT IN NEUTRAL AND RESTART THE ENGINE. RECORDS OF ALL VISITS FOR THE PROBLEM AT DEALERSHIP. NEVER COULD SOLVE PROBLEM, BUT TOO UNSAFE TO DONATE TO MY GRANDSON. IF SOMETHING WERE TO HAPPEN TO HIM BECAUSE OF A DEFECT THAT WAS NEVER FOUND, I DON'T KNOW WHAT I'D DO. CANNOT CHECK TRANSMISSION FLUID LEVEL. SEALED. I DO HAVE SOME FLUID STAINS ON MY DRIVEWAY. FOR YEARS I'VE REPORTED TO THE DEALERSHIP AND SPECIFIED THE CONCERN FOR SAFETY BUT TO NO AVAIL. IT KILLS ANYTIME. MAY NOT DIE FOR A WEEK, OR TOMORROW, OR EVEN A MONTH. NO PARTICULAR PATTERN. FEELS LIKE A TRANSMISSION PROBLEM. IF I'M SITTING IN A PARKING LOT WITH MOTOR RUNNING, SOMETIMES IT JUST KILLS. IT'S THE SHIFTING TO NEUTRAL WHILE DRIVING ON HIGHWAYS AND STREETS TO RESTART WHILE MOVING I'M WORRIED ABOUT. I'VE HAD SEVERAL MECHANICS CLAIM THEY FIXED IT BUT TO NO AVAIL. PLEASE GIVE ME SOME DIRECTION. ALL THE SHOPS I'VE GONE TO ARE REPUTABLE BUSINESSES. ONE MECHANIC SAID THE ELECTRONIC BRAIN (COMPUTER BOX) MIGHT BE CAUSING AND SAID TO SEND IT TO MERCURY FOR RECALCULATION. I DON'T KNOW ABOUT THAT. MOST OF THE READ OUTS ARE EPA RELATED.

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.

SEATS
WHEN I AM DRIVING THE CAR THE SEAT WILL MOVE BACK ON IT'S OWN VOLITION INTO EXIT POSITION. THIS HAPPENS WHEN IT GOES OVER A BUMP OR IF THE KEY IS JIGGLED IN THE IGNITION. IT HAPPENED IN MULTIPLE SITUATIONS LAST WEEK. VERY FRIGHTENING AS I HAVE TO SCRAMBLE TO REACH THE BRAKE AND ALSO MOVE THE SEAT BACK INTO POSITION. I HAVE TURNED OFF THE EASY EXIT OPTION SO THIS HAS STOPPED IT BUT IT UPSETS ME THAT I NO LONGER HAVE A FEATURE THAT I PAID FOR.

WHILE DRIVING THE VEHICLE THE INTERIOR LIGHT TURNS ON AND THE SEAT MOVES BACK INTO THE PARK POSITION. THIS IS A SAFETY ISSUE AS IT IS DIFFICULT TO REACH THE PEDAL/BRAKE AND IT HAPPENS WITHOUT NOTICE. THERE IS NO RHYME OR REASON TO THIS PROBLEM. I HAVE SEEN MULTIPLE POSTS REGARDING THIS ISSUE AND DON'T SEE HOW IT CANNOT BE A RECALL FOR SAFETY REASONS

AFTER APPROXIMATELY 90,000 MILES THE DOME LIGHTS TURNED ON AND AUTOMATIC SEATS MOVE BACK WHILE DRIVING. THIS ISSUE PERSISTS AND OFTEN OCCURS SEVERAL TIMES. THERE ARE SEVERAL COMPLAINTS OF THIS ISSUE FOUND ONLINE. IT IS NOT DUE TO A HEAVY KEY CHAIN AS I ONLY HAVE THE FOB AND KEY ATTACKED. THIS IS A SAFETY ISSUE AS THE SEATS PULL THE DRIVER AWAY FROM THE PEDALS AND STEERING WHEEL. INVESTIGATE! RECALL!

ELECTRICAL SYSTEM
WHILE DRIVING DOWN THE ROAD, THE SEAT WILL SUDDENLY MOVE BACKWARDS TO THE "OPEN DOOR" POSITION, AS THOUGH THE KEY HAD BEEN PULLED OUT OF THE IGNITION. THIS CREATES A VERY DANGEROUS SITUATION, ESPECIALLY FOR PEOPLE WITH SHORT LEGS, AS ONE CAN NO LONGER REACH THE GAS PEDAL OR BRAKE. SLIGHTLY "WIGGLING" THE KEY OR IGNITION SWITCH WILL USUALLY GET THE SEAT TO MOVE BACK TO THE PRESET DRIVING POSITION. WHEN THIS HAPPENS, THE INTERIOR LIGHTS ALSO GO ON, AND TURN OFF WHEN THE SEAT MOVES BACK INTO POSITION. THIS SEEMS TO HAPPEN AT ALL DIFFERENT SPEEDS, AND IT SEEMS MOST EVENTS HAPPEN AFTER THE CAR HITS A BUMP, BUT NOT ALWAYS. THERE HAVE BEEN TIMES WHEN IT JUST SEEMS TO HAPPEN WITHOUT ANYTHING TO SET IT OFF. IT ALSO CAN HAPPEN WHEN THE VEHICLE IS FIRST STARTED UP, OR JUST AS YOU START TO SHUT THE VEHICLE OFF. IT IS ABSOLUTELY RIDICULOUS THAT REPAIR OF THIS CONDITION IS NOT A RECALL ITEM. THE DATE SHOWN FOR WHEN IT HAPPENED IS THE LATEST DATE - I HAVE NOT DRIVEN THE VEHICLE SINCE THEN - BUT IT HAS BEEN OCCURRING FOR AT LEAST THE LAST 10 MONTHS.

WHILE DRIVING THE VEHICLE, THE SEAT SUDDENLY WENT ALL THE WAY BACK AND THE INTERIOR LIGHTS CAME ON. THIS HAS HAPPENED SEVERAL TIMES SINCE THEN, WE FINALLY FIGURED OUT IT WAS THE IGNITION, WITH THE CAR ACTING LIKE THE KEY JUST GOT PUT IN THE IGNITION OR JUST PULLED OUT, AND THE SEAT MOVING ALL THE WAY BACK FOR EASIER INGRESS/EGRESS AND THE COURTESY LIGHTS COMING ON. SINCE I AM ONLY 5 FOOT 4 INCHES, WHEN THE SEAT MOVES BACK I CAN NO LONGER REACH THE PETALS, A VERY DANGEROUS SITUATION WHILE DRIVING.
