My 2004 GMC Yukon started having speedometer troubles a few months ago. Sometimes it would work just fine, but sometimes it would read 120 mph when I was parked, or sometimes it would read 0 mph when I was going about 65 on the highway. Some days it would work just fine, other days, it was very off. It got to where I could not rely on my speedometer to tell how fast I was going. I had to use a gps to get my speed.

"stability system disabled" was displayed prior to the brakes being engaged without driver input. The vehicle was taken to the dealer and a 'yaw sensor' replaced. The problem returned within 20 miles. A second sensor was replaced along with reprogramming. The problem continues. Dealer states "GM has told us to do nothing more". no further explanation is offered by the dealer or GM "customer assistance". I believe that a vehicle that activates brakes on dry pavement without the driver's foot on the pedal is dangerous.

2004 GMC Yukon slt -- instrument panel when truck was started. All gauges (fuel, battery & water) became inactive. Shift indicator no longer worked and I was unable to determine what gear the car was in. Audio system (cassette, cd player and radio) became inoperable. Car taken to dealership -- beck & masten North in houston. I was told that the body control module was defective and would need to be replaced. Previous issue with the instrument panel cluster going out, causing speedometer to become inoperative. Dealer admitted that this was a problem on a number of Yukon. (I haven't seen this a a recall on either your site or GMC's site.) GMC has violated FMVSS standard no. 101 and parts 573 and 577.
