The gauges in the instrument cluster stop working. First the speedometer then the tachometer, and now the amp meter. On going problem. Definately a safety concern but no one wants to address the issue. The dealer wants 600.00 dollars to repair ir but does not guarantee it will be the fix. Other vehicals of this year and model have the same issue.

Days after purchasing the vehicle, the check engine light came on, the vehicle powered down taking the speed from 35mph or above to 5-10 miles MPH with out warning. This continuously happened as years passed and gm certified repair shop never found what's wrong. Until about two years ago, I googled issue and found its related to accelerator pedal and wiring from pedal that leads to engine throttle control, I changed throttle control plug to new and replaced accelerator pedal with used part and worked fine for two years but has now started failing again. I am afraid of this issue because I could be on freeway going 65 MPH and if these fail as they have and are, I then slow down to 5-10 MPH in a matter of seconds and could cause a serious accident. Please help, there should be a recall for this.

I was going to work and notice my speedometer was not moving...and the rmp reading was not moving. I check with my machanic and the price was over $600. To fix and all the cables have to be replaced because they are all put together. Gmc know there's a problem with the speedometer cables. We have a 94 gmc and no problem with the speedometer.

Fuel gauge reading inaccurately. Needle went way past the full mark into the blank area on the bottom of the gauge. Also, the speedometer was reading 120mph when I was pulling out of my driveway. I stuck at 70mph when I was stopped.

Traction active appears on display - while stopped at a very dangerous intersection, I pressed the accelerator only to have the traction active light appear on the display and the vehicle would not move. I had to let off the gas and then press it again in order for the vehicle to move. This is a major safety concern as I am unable to accelerate at an appropriate speed in order to avoid an accident while taking off from a stop.
