POWER TRAIN
The contact owns a 2007 Mercury Mountaineer. The contact stated that after shifting the transmission from park(P) to reverse(R), the vehicle failed to respond. The contact removed and reinserted the fob key in the ignition to correct the failure. The vehicle was taken to an independent mechanic, who diagnosed that an unknown transmission part needed to be replaced. The vehicle was not repaired. The mechanic instructed the contact to pull the park release lever each time to shift the vehicle out of park (P). The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 78,000.

SEAT BELTS
I buckle the seat belt and it just comes unbuckled spontaneously when I’m driving. I check to see if the seat belt is secure by pulling on it. It seems secure but still unbuckles. I usually have to redo my seatbelt every 5 minutes. I do not feel like it will keep me safe in a collision

TIRES:SIDEWALL
My husband had purchased 4 brand new COOPER TIRES EVOLUTION H/T M+S size P235 / 65 R 18 a number of years ago. My husband has since passed away. I cannot find my sales receipt due to the fact my husband had paid for the tires in question. I do not know what he did with the sales receipt. I have a few good-faith efforts and attempts to bring this matter to COOPER TIRES but each and every time I got the same reply from them "NO we cannot help you. We will not be able to warranty your tires for you......we need a sales receipt......" I had my good friend take my vehicle to a local tire dealer and installer recommended by COOPER TIRES and this tire dealer found that: (1) all 4 COOPER TIRES on my vehicle look and are brand new (2) tire tread depth on all 4 COOPER TIRES on my vehicle are 8/32 " (3) three COOPER TIRES on my vehicle show a DOT date code of 2017 and one COOPER TIRE on my car shows a DOT date code of 3817 (4) all four COOPER TIRES on my vehicle have numerous cracks on the sidewall of the tires which is a manufacture defective and COOPER TIRES should replace all 4 tires on my car (5) the right-rear COOPER tire on my vehicle is leaking air from the sidewall due to the cracks. (6) COOPER TIRES should under the law include my tires under their national recall list because the COOPER TIRES on my vehicle have the same (1) make and model tire (2) the exact same size tire (3) all 4 COOPER TIRES on vehicle were made in the same factory as the rest of the recall tires (4) three of the COOPER TIRES on my vehicle have an issue with the date code (see recall NHTSA Campaign Number: 21T014000 for more info). I could go on and on but I think you get the idea. Also, I will hold COOPER TIRES legally liable if I get into a car accident due to its manufacture defective COOPER tires. The exact dates my good friend has contacted COOPER TIRES are: (1) May 01, 2024 (four times); (2) May 02, 2024 (three times). I asked for a call back but nobody returned my call.

It happens every time I drive this vehicle. The ignition is lose, so the key jiggles and if their is too much bumping or shaking the key slightly moves and the seat and interior lights come on now I’ve tried Combat the issue with keeping the lights off on the interior and thought maybe I could turn off the seat function still haven’t figured that out yet

UNKNOWN OR OTHER
I was driving on the expressway and my truck just shut off. The car panel Illuminati to a check engine light and a wrench. I had to put on my caution light and make it to the shoulder. That was scary. I sat for 10 minutes before it started back up. I've taken it to the dealership and all they did was guess what the problem could be. They said it might be the fuel pump or something electric or the computer. That's not doing me any good, because I'm still having this problem.

HAD TO REPLACE TRANSMISSION COMPLETELY AT 137,000 MILES. THERE'S BEEN A LOT OF COMPLAINTS ABOUT THESE TRANSMISSIONS AT THIS MILEAGE AND FORD SHOULD BE RESPONSIBLE FOR SOME OF THE COST. THIS IS RIDICULOUS.

I HAD TO REPLACE THE TRANSMISSION AND SOME OTHER RELATED PARTS IN MY VEHICLE AND I WAS INFORMED BY A DEALERSHIP THAT THERE WAS A "SILENT RECALL" ON THIS TRANSMISSION AND THAT EVEN THOUGH FORD MOTOR COMPANY WAS AWARE OF THE ISSUES AS EARLY AS 2000 THEY CONTINUE TO INSTALL THEM IN VEHICLES. IF YOU LOOK ONLINE YOU WILL SEE QUITE A NUMBER OF COMPLAINTS ON THIS TRANSMISSION. I FEEL SINCE FORD KNOWINGLY KEPT USING THESE TRANSMISSIONS AND WAS WELL AWARE OF THEIR POSSIBLE FAILURE WHEN THEY REACHED 130,000 MILES THAT THEY SHOULD BE RESPONSIBLE FOR AT LEAST A PORTION OF HE COSTS IF INDEED, NOT ALL OF THE COST OF REPLACEMENT. WHAT HAPPENS WHEN A CAR COMPANY PUTS OUT A SILENT RECALL? DO I HAVE ANY RIGHTS? I HAVE ALREADY SENT A CERTIFIED LETTER TO FORD MOTOR CUSTOMER RELATIONS IN DEARBORN, MI AND I HAVE A SIGNED RECEIPT THAT THEY ACCEPTED MY LETTER BUT THEY HAVE NOT BOTHERED TO CONTACT ME AT ALL. WHAT ARE MY OPTIONS AND IS THIS SOMETHING YOU CAN HELP ME WITH? THE FIRST TIME THIS TRANSMISSION CAUSED A PROBLEM WAS WHEN WE WERE IN 5 PM TRAFFIC ON A ROAD WITH A SPEED LIMIT OF 55 MILES AN HOUR AND THE CAR JUST STOPPED LEAVING MY FAMILY IN THE MIDDLE OF A BUSY TWO LANE ROAD WHICH WAS VERY DANGEROUS. WE WERE FINALLY ABLE TO GET THE VEHICLE TO THE SHOULDER. I CAN FORWARD MY BILLS AND COPIES OF ONLINE CONVERSATIONS REGARDING THE FAILURE OF THESE TRANSMISSIONS.

ELECTRICAL SYSTEM
I WAS DRIVING HOME ON A BUSY CITY STREET WHEN I STOP AT A STOP LIGHT TO TURN RIGHT. WHEN I WENT TO ACCELERATE MY MERCURY MOUNTAINEER WHEN IN TO LIMP MODE. AS I INSPECTED THE SUV FOR PROBLEMS I NOTICED THE MY ENGINE/TRANSMISSION WIRE HARNESS WAS BRITTLE AND EXPOSING BARE WIRE AND THAT THE WIRES WERE TOUCHING EACH OTHERS CAUSE THEM TO SHORT OFF THE VEHICLE COMPUTER SYSTEM AND FRYING ELECTRICAL COMPONENTS. IT ALSO CAUSED THE TRANSMISSION TO MALFUNCTION AND SHIFT WRONG WHICH IN TURN CAUSING THE TORQUE CONVERTER TO FAIL AND DESTROY THE TRANSMISSION.

AIR BAGS
I AM RECEIVING FALSE READINGS AS TO THE ACTIVATION OF THE AIR BAGS. THIS HAPPENS WHEN I AM STARTING THE VEHICLE AND ALSO WHEN I AM OPERATING THE VEHICLE ON THE HIGHWAY. I CAN TURN THE VEHICLE OFF AND RESTART IT, AND SOMETIMES THE INDICATOR WORKS PROPERLY AND SOMETIMES IT DOES NOT. I EXPERIENCE THE SAME PROBLEM SOMETIMES WHEN THE PASSENGER SEAT IS OCCUPIED. MY CONCERN IS THE FACT I DON'T KNOW IF MY AIRBAG IS OPERATIONAL OR NOT. I CONTACTED MY LOCAL DEALER AND WAS INFORMED I WOULD BE CHARGED $99 TO JUST HAVE IT CHECKED. I HAVE NOT DONE SO.

INTERMITTENTLY, THE SEAT MOVES TO THE 'EASY EGRESS' POSITION WHILE THE CAR IS IN MOTION. THE DOME LIGHT COMES ON, AS IT WOULD IF YOU WERE GETTING OUT OF THE CAR. FROM READING THE MANY SIMILAR COMPLAINTS, I AGREE THAT IT HAPPENS WHEN BRAKING OR TURNING AND IT HAPPENS AT ALL SPEEDS. THIS STARTED HAPPENING ABOUT ONE MONTH AGO. NO ACCIDENT YET BUT IT'S VERY JARRING AND DANGEROUS.

SEATS
WHILE DRIVING MY CHILDREN TO SCHOOL THIS MORNING MY SEAT ADJUSTED ITSELF A COUPLE OF TIMES SO THAT I HAD A DIFFICULT TIME REACHING THE PEDALS UNTIL I COULD GET IT BACK TO THE PROPER POSITION. THIS HAS HAPPENED BEFORE BUT I THOUGHT IT WAS A "FLUKE". TODAY, WHEN I PICKED MY KIDS UP AND DROVE HOME IT HAPPENED 7 TIMES IN 3 MILES AND ALMOST CAUSED ME TO HIT A PEDESTRIAN. THIS HAPPENED ON A CITY STREET. I WAS UNABLE TO ISOLATE A "TRIGGER" TO THE MOVEMENT. ONE TIME I WAS GOING ABOUT 30 ON A STREET, ANOTHER TIME I WAS SLOWING DOWN TO A STOP SIGN AT A BUSY INTERSECTION.
