Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 GMC Yukon Owner Comments

problem #13

Nov 132015


  • 168,500 miles


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.

As I was driving on 95N of college park, md, my vehicle power seem to shutdown on the highway and the "reduce power engine" message appeared in my instrumentation panel. Fortunately I was close to the emergency pull off of the left lane to get out of traffic. I turned the truck off and back on, and the message went a way. I was able to continue to with my journey. However, just recently, it has done it again, this time my speed was around 35mph. Once again, I turned it off, than on and the message went away and I had power in my acceleration again. This is very dangerous. I'm taking it back in to the mechanic to have them look at it.

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.

I have heard of several accidents because of reduced engine power. It slows the vehicle down and people behind them rearended them because it is a sudden drop in speed and there is no time to slam on the brakes please get this fixed before a child is injured or killed thank you.

My vehicle is a 2003 GMC Yukon. The speedometer is not registering, and when (the gauge) is trying to operate, the vehicle hesitates while accelerating and the gauge does the same as well as the gas gauge. I know all my dashboard gauges need to be checked for malfunction. This began two weeks ago, I called doug henry of farmville to check my vehicle for recalls, only to find out it is not listed. My husband has a 2003 GMC Yukon XL, he received a letter describing this problem and got information to get it fixed free of charge. I am not responsible for this problem and I believe there are other vehicles affected in this particular recall.

Contact stated the speedometer and gas gauge failed. The needle on the speedometer moved, but it said 100 mph when going only 5 mph. He took the vehicle to the dealership, and they stated it was a common problem and usually happened at 30,000 miles. They were able to diagnose the problem without looking at the vehicle. He has not contacted the manufacturer and the vehicle has not been repaired.

While driving or idling, the "check engine light" is displayed. Engine goes into "reduced power mode". dealer replaced accelerator control module. This did not correct the problem. They now think it is the throttle body. Time will tell, mean while I am without my $45,000 truck.
