NHTSA Complaint #10790375 — 2006 MERCURY MOUNTAINEER

SHORTLY AFTER PURCHASING MY MOUNTAINEER THE ELECTRIC RUNNING BOARD ON THE DRIVER SIDE BEGAN TO MAKE A GRINDING SOUND. BOUGHT FROM A DEALER IN WA STATE AND MOVED TO WI STATE WHERE THE DRIVER SIDE STOPPED AND THE PASSENGER SIDE STOPPED EXTENDING/RETRACTING. MOVED TO NJ AND WE HAD PURCHASED THE VEHICLE EXTENDED WARRANTY. BEGAN TO SOUND LIKE A KNOCKING SOUND WITH LITTLE POWER AND HAD TOWED TO DEALER. THERE THEY FOUND ALL 8 SPARK PLUGS FOULED, DRIVER SIDE HAD 3 EXHAUST MANIFOLD BOLTS LOOSE. PASSENGER SIDE HAD SAME 3 LOOSE, BUT ALSO HAD 2 BROKEN OFF IN EXHAUST MANIFOLD PLUS THE MANIFOLD ITSELF HAD A HAIRLINE CRACK. IN THE END, I PAID ALMOST $2,000 TO HAVE DRIVER AND PASSENGER RUNNING BOARD AND MOTORS REPLACED. THE REAR WINDSHIELD WIPER MOTOR HAD GONE BAD AND WAS REPLACED, THE SPARK PLUGS AND ALL MANIFOLD BOLTS (ALONG WITH BROKEN) WERE ALL REMOVED AND REPLACED.
