Speedometer randomly sticks, or accelerates to maximum. Oil pressure gauges max out as well. Very dangerous to drive with no concept of speed, and also very illegal. When I stop the vehicle, I can turn off the engine. If I continue to turn the key 90% (but not enough to start the engine), and let off, the gauges will drop up to 5%. after 5 minutes of resetting the instruments, the gauges will reset. However, the next time I drive I might be going through a school zone at 40 instead of 25, but my speedometer says 80. Clearly unsafe.

My brakes would engage but they will not disengaged and my brakes are buringing and smelling like burnt rubber. Brakes are also sticking. The electrical system keeps blinking on and off. Replace fuse but still not working. Not displaying the correct speed on dash board I'm going slower than the speed say.

The contact owns a 2003 GMC Yukon. While driving various speeds, the reduced engine power and stability system disabled indicators illumianted on the instrument panel. The vehicle suddenly experienced a loss in acceleration. The failure recurred for a span of three years. The dealer was unable to duplicate the failure. The manufacturer was not notified. The approximate failure mileage was 100,000.

Wife driving truck to work " reduced engine power", message came on the dash, and also said traction control was disabled. Power was reduced gradually to ten miles per hour. She floored the gas, nothing. Turned it off, restarted it, nothing. Engine light and traction disabled lighted were illuminated. Also the rear mirror temperature display flickers all the time. Drl burn out almost daily. Gmcs have major electrical issues before people start dying. Imagine a car shutting down on you while on the highway. That an accident waiting to happen. The rear wiper works when it feels like working, there is also a message about fixing the ride control. For all the bail money GMC got, they should recall these mistakes they made.

Hello, when im driving down the road the reduced engine light comes on. This is very dangerous since it also happens on the highway. When I shut the car off and let it sit for 3 or 4 min and restart it will happen again about 2 miles down the road. GMC says they know about the issue but they do not have a fix for it. I have taken it to several shops and they say that GM says the same thing ( we know about the issue but do not have a fix for it). There should be a recall on these vehicles do to this happening and could cause a major accident. There are alot of other ppl having this same issue. Thanks
