TL*- THE CONTACT OWNS A 2006 GMC ENVOY DENALI. THERE WAS A VIBRATION IN THE VEHICLE WHEN THE GAS PEDAL WAS APPLIED WHILE TRAVELING BETWEEN 30 AND 40 MPH. THE VEHICLE WOULD ALSO VIBRATE AT ANY SPEED. IT FELT AND SOUNDED AS IF IT NEEDED TO SHIFT GEARS, AS IN A MANUAL VEHICLE, BUT WAS IN THE WRONG GEAR. IT WAS INVOLVED IN A CRASH IN NOVEMBER 2006. TWO DEALERS STATED THAT THERE WAS A TECHNICAL SERVICE BULLETIN THAT REFERENCED THE FAILURE, BUT THERE WAS NOTHING THEY COULD DO TO CORRECT IT. WHEN ENGAGING THE BRAKE THE VEHICLE WOULD MOVE FORWARD AND A NOISE COULD BE HEARD. THE NOISE FREQUENTLY OCCURRED AFTER A QUICK STOP. THIS FAILURE HAD OCCURRED DURING THE SAME PERIOD OF TIME. THE DEALER DIAGNOSED THE FAILURE, AND STATED THEY HAVE REPAIRED THE NOISE, BUT IT CONTINUED TO OCCUR. THE CURRENT MILEAGE WAS 14,000, AND THE FAILURE MILEAGE WAS 13,118.*AK
