2005 GMC Yukon Denali Electrical system Problems

“I was driving on the 55 freeway, and all of a sudden my electrical GPS, radio, and power turned off for approx. 5 sec. And the dash rebooted, and radio remained off, and the car was still cruising, but losing speed. I put the car in neutral and had to restart while cruising. It is not the first time this has happened. Spoke to Gmc parts dept. On the phone, and he stated there is no recall for this vehicle. This has happened approx. 5 times. I shared that information to the parts dept. …”

“I started having problems with my speedometer cluster about 1 year after purchase. It worked most of the time so didn't take it in for repair under my warranty. After 3 years it stopped working altogether but I was no longer under warranty. I called the dealer to see if there was a recall and he said there was but I had too many miles on the vehicle to qualify. So I have been driving without a working speedometer for the past two years.”

“Speedometer failure on my 2005 Yukon Denali. Needle gets stuck and wont return to normal position. Auto manufacturers have been installing speedometers in cars for over 100 years. Vehicle is only 3 years old and has 50,000 miles. Gmc wont recall because not enough people have complained, but yet 03-05 were recalled in the same model. I feel this creates a costly repair people shouldn't have to make on such new vehicles and should be part of a safety recall.”

“It appears in my investigating this through online searches and forums, there are 1000's of GM vehicles that have had their speedometers quit working and is quite a money maker for GM and their dealerships, since they 'have' to do it so it can be reprogrammed for mileage authenticity! With these 1000's of GM vehicles having faulty speedometers, or other faulty gauges...mine is stuck on 120mph!! Definitely a safety issue when u really don't have any idea how fast you are going!! I think this is something they are well aware of, and not because of normal use and wear!! …”

“For approx8 months my speedometer has not work properly. As I'm driving the zero may be anywhere from real zero to 120 MPH. It is very difficult due to the sensitivity of the RPM gauge to tell me exact speed. Currently I drive with a garman that tells me how fast I'm going. I've found lots of information related to speedometer issues on 2005 gms Yukon Denali. The dealership says there was a recall but the speedometer but I had exceeded the mileage. What difference does that make? The dealership says it would be about $350 dollars to fix the problem. …”
