Open the full vehicle complaint log (all categories)TL* THE CONTACT OWNS A 2005 MERCURY MOUNTAINEER EQUIPPED WITH FOUR COOPER DISCOVERER H/T TIRES, SIZE: 245/65R17. THE CONTACT STATED THAT ALL FOUR TIRES RUMBLED AND RODE ROUGHLY INSTEAD OF PROVIDING A SMOOTH, STABLE RIDE WHILE DRIVING AT ANY SPEED. THE VEHICLE WAS TAKEN TO A TIRE FACILITY MORE THAN FIVE TIMES, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE MANUFACTURER WAS CONTACTED, BUT HAD NOT REQUESTED THAT THE TIRES BE SENT TO THEM FOR TESTING. THE CONTACT WAITED OVER TWO YEARS FOR A RESPONSE FROM THE MANUFACTURER AND DECIDED TO REPLACE THE TIRES ON HIS OWN. ONCE THE TIRES WERE REPLACED, THE RUMBLING STOPPED. THE DOT NUMBER, VIN, AND TIRE AND VEHICLE FAILURE MILEAGE WERE UNKNOWN.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
