MY 2003 YUKON HAS A SPEEDOMETER PROBLEM. THE MPH WILL BECOME LOCKED IN ON SPEEDS THAT ARE NOT ACCURATE. TODAY I WAS DRIVING ACCORDING TO THE SPEEDOMETER 110 MPH, BUT ACTUAL SPEED LESS THAN 40 MPH. THIS PROBLEM HAS OCCURRED MORE THAN 40 TIMES IN THE LAST MONTH. WHEN I STOP THE VEHICLE THE SPEEDOMETER NEEDLE AT TIMES WILL NOT RESET TO 0 MPH. I HAVE HAD THIS PROBLEM FOR A WHILE, AND HAVE FOUND OUT THAT SOME FRIENDS WITH SIMILAR VEHICLES(GMC PICK UPS) HAVE THE SAME PROBLEM. I WAS ADVISED BY THE DEALER THAT THIS A PROBLEM THAT IS BECOMING MORE FREQUENT! *NM
DT*: THE CONTACT STATED ON THREE OCCASIONS WHILE DRIVING AT HIGHWAY AND FREEWAY SPEEDS OF 30- 75 MPH THE VEHICLE MADE A LOUD GRINDING NOISE FOLLOWED BY ANOTHER LOUD BANG. THE VEHICLE STALLED AND FILLED WITH WHITE SMOKE. THE VEHICLE WAS TOWED TO A LOCAL DEALERSHIP EACH TIME. THE ENTIRE A/C WAS REPLACED ON TWO OCCASIONS. ON ANOTHER OCCASION VARIOUS PARTS OF THE A/C WAS REPLACED. ON THREE OTHER OCCASIONS THE VEHICLE WOULD NOT START AND WAS TOWED EACH TIME. THE BATTERY WAS REPLACED A TOTAL OF THREE TIMES. THE PROBLEM STILL PERSISTS.
I STARTED MY TRUCK. I APPLIED THE BRAKES AND SHIFTED INTO DRIVE. I BEGAN TO ROLL FORWARD, THEN APPLIED MY BRAKES PRIOR TO EXITING MY DRIVEWAY. THE BRAKE PEDAL WENT TO THE FLOOR, THE BRAKE SERVICE LIGHT CAME ON AND THE TRUCK CONTINUED FORWARD. I HAD TO PUMP THE BRAKES TO COME TO A STOP. I PULLED THE TRUCK OVER AND OBSERVED BRAKE FLUID ALL OVER THE STREET. I CRAWLED UNDER THE TRUCK AND SAW THAT THE BRAKE LINE WAS RUSTED AND THAT IT BURST SOMEWHERE IN THE MIDDLE OF THE TRUCK ON THE DRIVER'S SIDE. *TR
