Within that volume, owners reported 6 crashes, 0 fires, 1 injury, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 1 active recall campaign, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 3 investigation files overlapping the 2007 MOUNTAINEER. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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

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.

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.

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.
