I HAVE A 2004 GMC YUKON. THE SPEEDOMETER IS MALFUNCTIONING ,IT DISPLAYS INCORRECT ERRATIC SPEEDS, MAXING OUT AT 40 MPH NO MATTER HOW FAST I AM DRIVING. RECENTLY ON A LOCAL FREEWAY I ALMOST HAD A ACCIDENT WHEN THE TRAFFIC SLOWED AHEAD AND I THOUGHT I WAS GOING 30 MPH BUT MY ACTUAL SPEED WAS ABOUT 65. IT NEARLY KILLED ME. I HAVE CONTACTED GMC BUT HAVE NOT HAD ANSWER TO THIS PROBLEM.

ELECTRICAL SYSTEM
THE PASSENGER DOOR AND RIGHT SIDE REAR DOOR LOCKS HAVE FAILED. THE DOORS HAVE TO BE MANUALLY LOCKED AND UNLOCK. I BELIEVE IT TO BE THE DOOR LOCK ACTUATORS, AS THEIR ARE NUMEROUS COMPLAINTS ABOUT THIS ALL OVER THE INTERNET. THIS IS A HUGE SAFETY ISSUE. I CANNOT BELIEVE THIS HAS NOT BEEN RECALLED. I HAVE TWO SMALL CHILDREN AND TO NOT BE ABLE TO GET TO THEM AS FAST AS POSSIBLE IN AN EMERGENCY IS VERY SCARY. THESE AUTOMATIC DOOR LOCKS ARE THERE FOR A REASON GM KNOWS IT. I WAS TOLD THE COST WOULD BE AROUND $300 PER DOOR AND MANY OF THESE PEOPLE HAVE HAD TO HAVE THEM REPLACED MULTIPLE TIMES. THIS NEEDS TO BE FIXED FREE OF CHARGE WITH QUALITY PARTS THAT WILL NOT FAIL! *TR
