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. And he stated that they could do a diagnostic that would cost a pretty hi amount to check, and if nothing come out of it I asked. Then he stated nothing.

My 2005 gmc yukon denali rear tailgate / hatch is locked and the electronic lock motivator will not open the rear tailgate / hatch. There is no key nor manual way to open rear tailgate / hatch. The dealer said that they were not sure what it would cost to fix although it would be no more than $450.00. Since this vehicle has three rows of seats there is no manual way to open this rear tailgate / hatch for the passengers in the third row of seats to get out in case of an emergency. The manufacturer should have included an alternate way to open this hatch for emergency's. Whether it would be a key from the outside or a door handle on the inside. We feel that type of vehicle should be reviewed and it should include various years of this gmc vehicle, the chevrolet tahoe, and the chevrolet suburban which have the same setup for this safety reason. Thank you for your assistance and review of this safety issue.

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!! My 2005 gmc yukon denali would cost $510 + tax and have to b sent away to b repaired.... Please investigate this and add this to all the other problems gm is having and let's not put it to the consumer like they have and are doing! Thank you!!

Passenger headlight (low beam) has been replaced twice. Intermittently goes on and off. Same with 2 out of 3 brake lights. Doesn't matter how many times we replace the bulbs, we keep having the same problem. Is gmc going to pay my ticket when I get pulled over?

Tl*the contact owns a 2005 gmc yukon denali. While the vehicle was parked the contact noticed the gear indicator light on the instrument panel was not functioning. The vehicle was taken to the dealer when the contact noticed the light was dim. The dealer could not diagnose the failure because the vehicle had not completely shut off. The light completely turned off and was not taken to the dealer for diagnostic testing. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 65,000.

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. I want to know what the problem is but diagnostics also carry a pretty hefty fee.

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 sporadically fails to indicate actual speed or zero. It sometimes locks up a specific speed and does not move when speed changes. Sometimes no speed indication at all..
