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

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.

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.

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.

IT ALSO CAUSED THE TRANSMISSION TO MALFUNCTION AND SHIFT WRONG WHICH IN TURN CAUSING THE TORQUE CONVERTER TO FAIL AND DESTROY THE TRANSMISSION.

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.

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.

MY 2007 MERCURY MOUNTAINEER NEVER HAD ANY PROBLEMS UNTIL RECENTLY, THOUGHT IT WAS THE TRANSMISSION BECAUSE OF THE WAY IT DROVE. TOOK IT TO THE MECHANIC AND GOT TRANSMISSION FLUID PUT IN BUT THE PROBLEMS REMAINED THE SAME AND WAS TOLD THE TRANSMISSION WAS FINE. MY THERMOSTAT HOUSING UNIT WAS LEAKING (THIS IS VERY COMMON WITH THESE CARS AND VERY DANGEROUS, NEEDS IMMEDIATE ATTENTION!) AND HAD CAUSED VERY EXPENSIVE WIRING ISSUES. ALMOST ACTS EXACTLY LIKE THE TRANSMISSION IS GOING OUT - RPM'S ARE WAY TOO HIGH, THE VEHICLE WOULD NOT ACCELERATE IN THE MIDDLE OF CITY TRAFFIC, THE CAR JUMPED AT A STOPLIGHT AND CAUSED ME TO HIT THE CAR IN FRONT OF ME, AND IT DOESN'T SHIFT PROPERLY. PROBLEMS OCCURRED OUT OF NOWHERE AND ARE TOO DANGEROUS TO BE IGNORED BUT VERY EXPENSIVE TO BE FIXED. ITS VERY COMMON AND SHOULD BE RECALLED BEFORE SOMEONE GETS SERIOUSLY INJURED!!!!

THE DRIVERS SEAT, WILL, WITHOUT WARNING, WHILE DRIVING ON THE INTERSTATE, AUTOMATICALLY START MOVING BACKWARDS TO IT'S DEFAULT POSITION. SOMETIMES THE INTERIOR LIGHT WILL COME ON SIMULTANEOUSLY. IN A PANIC, SO FAR, I HAVE BEEN ABLE TO STOP THE BACKWARD MOVEMENT BY GRABBING THE SEAT POSITION BUTTON AND FORCING IT TO MOVE BACK UP TO THE PRESET POSITION WHERE I HAVE BEEN ABLE TO GET MY FEET BACK ON THE PEDALS. THIS HAS OCCURRED MULTIPLE TIMES WHILE DRIVING FULL SPEED ON INTERSTATES, ON SIDE STREETS AND FRONTAGE ROADS AND EVERYTIME WITHOUT WARNING. ONE TIME, WHILE SITTING AT A STOP SIGN, I COULD NOT CATCH IT QUICKLY ENOUGH AND IT MOVED SO FAR BACK THAT MY FEET COULD NOT REACH ANY OF THE PEDALS! LUCKILY THAT TIME I WAS SITTING STILL. THIS HAS BEEN HAPPENING FOR THREE YEARS.

WHEN DRIVING THE VEHICLE AT ANY SPEED THE SEAT MOVES ALL THE WAY BACK AND THE INTERIOR LIGHTS COME ON. THIS ALSO HAPPENS WHEN YOU BRAKE OR GO OVER A BUMP. THIS IS VERY DANGEROUS TO SOMEONE OF MY SIZE BECAUSE WHEN THE SEAT GOES ALL THE WAY BACK I CAN NO LONGER TOUCH THE PEDALS. THIS IS HAPPENING VERY OFTEN AND I HAVE GOOGLED IT AND I CAN SEE THAT A LOT OF OTHER PEOPLE WHO OWN THIS YEAR MAKE AND MODEL ARE HAVING THE SAME PROBLEMS WITH THEIR VEHICLE. I HAVE TAKEN IT TO SEVERAL MECHANICS AND FORD DEALERS AND NOBODY SEEMS TO BE ABLE TO FIGURE OUT WHAT IS WRONG WITH IT.
