Open the full vehicle complaint log (all categories)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
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.
TL*THE CONTACT OWNS A 2007 MERCURY MOUNTAINEER. THE CONTACT STATED THAT VARIOUS SEAT BELTS WOULD NOT RETRACT PROPERLY. SHE TOOK THE VEHICLE TO THE DEALER ON SEVERAL OCCASIONS AND THEY REPLACED THE FIVE RETRACTORS FOR DIFFERENT SEATS IN THE VEHICLE. THE REAR DRIVER'S SIDE SEAT BELT WAS REPLACED AGAIN SEVERAL MONTHS AFTER THE ORIGINAL REPAIR. CURRENTLY, THE CAUSE OF THE FAILURE WAS UNKNOWN. THE FAILURE MILEAGE WAS 4,403 AND CURRENT MILEAGE WAS 27,900. UPDATED 02-23-09 *BF UPDATED 02/24/09. *JB
