NHTSA Complaint #10189097 — 2003 GMC YUKON XL

2003 GMC YUKON XL COMPLAINT #1. SPEEDOMETER IS ERRATIC. ODOMETER READS ONLY 79,000 MILES. A FEW MONTHS AGO, AFTER STARTING THE VEHICLE THE SPEEDOMETER JUMPED TO 60 MPH WHICH CAUSED THE NEEDLE TO READ 120 AT THE ACTUAL 60. IF YOU SHUT OFF THE IGNITION AND RESTARTED THE CAR, THE NEEDLE WOULD DROP ABOUT 5 MPH EACH TIME. IF YOU REPEATED THIS PROCEDURE (STARTING ENGINE, SHUTTING OFF ENGINE) AFTER 10-12 TIMES THE SPEEDOMETER WOULD READ ZERO AGAIN. THIS HAPPENED SEVERAL TIMES. YESTERDAY AS I PULLED OFF THE HIGHWAY, WHERE THE SPEED IS 75 MPH, AND PULLED ONTO OUR LOCAL ROAD WHERE THE POSTED SPEED LIMIT IS 50, I NOTICED THAT I WAS HOLDING UP TRAFFIC ALTHOUGH THE SPEEDOMETER READ 50. I FELT AS IF I WAS NOT ACTUALLY DOING 50 SO I SPED UP EVEN THOUGH THE NEEDLE READ 65MPH. I PULLED OVER TO SEE IF INDEED THE SPEEDOMETER WAS READING INACCURATELY, AND IT WAS. THIS TIME STUCK AT 15 MPH. I AGAIN REPEATED THE ENGINE OFF/ON PROCEDURE TO GET THE NEEDLE BACK TO ZERO, BUT NOTICED IT JUMPING AND NOT RESPONDING QUICKLY AT STOP SIGNS. I HAVE READ REVIEWS ABOUT COMPLAINTS WITH THE SPEEDOMETERS BUT DO NOT SEE YUKON XLS AS PART OF THE AFFECTED VEHICLES. THIS IS A VERY FRIGHTENING ISSUE AS I HAVE A 16-YEAR-OLD THAT WILL BE DRIVING THIS VEHICLE ON HER OWN IN JUST A FEW MONTHS. I BELIEVE GM SHOULD ADDRESS THIS BEFORE SOMEONE'S DRIVING RECORD IS TARNISHED FOR UNINTENTIONAL SPEEDING RESULTING IN TICKETS AND INSURANCE INCREASES...AND POSSIBLY EVEN ACCIDENTS RESULTING IN DEATH. COMPLAINT #2. FUEL GAUGE STICKS AT FULL MARK UNTIL APPROXIMATELY 1/4 TANK OF GAS IS USED, THEN GAUGE WILL DROP. ALSO STICKS AT 1/4 TANK THEN DROPS AGAIN TO EMPTY. DUE TO INABILITY TO PROVE THE PROBLEM AT THE DEALERSHIP WHILE UNDER WARRANTY, THE DEALERSHIP WOULD NOT REPAIR. *JB
