The instrument cluster panel on my 2005 GMC Sierra pick up constantly reads the wrong speed. At times it registers 0 mph when im actually driving or it reads 120mph when stopped. Also the oil pressure gauge is pegged out. There sames to be alot of complaints for the same thing on the year and model, you need to make GM do a recall on this.

My speedometer quit working around 78,000 miles. Slowly but surely all my other gauges have quit working over time. The RPM gauge, speedometer, oil temp, and gas gauge. Only one works now. The rest either don't work or fluctuate back and forth. I would have reported this earlier if I knew about this site. It's not the first complaint so there is something up with these models. They should be recalled and fixed by the dealers. I won't ever buy another GMC vehicle. That's for sure.

Within 4 months of purchase, was driving at approx. 25 mph when transfer case shifted into 4 high on it's own. Shut off vehicle, restart and able to put back into 2 wheel drive. Happened on and off for a little more than a month when it went to 4 lo while driving at 30 mph through town. Unable to reset. Limped it the 2 miles to dealership for diagnosis. Cost me $1200 to have the transfer case rebuilt. Smoked the clutch pack, burned out 2 bushings and bent shift shaft. Had second issue of shifting on it's own, May 15th, 2014. This time it cost me $500 for the shift motor to be replaced. Second problem, speedometer reading incorrectly or not at all. Been going on for about 3 years sporadically (apparently the little drive "motor" on the back of the instrument cluster, $300 replacement or, found a company to rebuild with new "motors" for under $200). Passlock issues started in Jan 2014, has left me stranded a couple times now. Can't get a good answer from dealer as to how to repair other than "bring it in and we'll hook it to our diagnostic system" (I.e. pay us lots of money). Also having issue with check engine light on constantly. Intermittent engine miss on multiple cylinders. Rough idle, crappy mileage, but not down on power. Miss seams to go away off idle and not noticeable under load. New plugs, wires, etc, etc, etc.... haven't figured this one out yet. Same answer from dealer (pay us more money please). Lastly, air bag light came on in Dec of 2012. Never crashed or bumped but had to replace left front air bag sensor. Love the truck, currently has 154000 miles but I'm getting frustrated with all the little electrical "glitches" and the dealer won't help a bit without the normal answer, "bring it in and we'll hook it to our diagnostic system". it's dang near $200 (diagnostic charge) just to get my truck in and out without even getting anything repaired!

My vehicle was parked in my driveway. I was walking down the driveway and thought the car was being stolen as it was starting. There was no one in the car. The car did start several times on its own so I disconnected the battery cable and had it serviced immediately. How long it had been doing this I do not know. I do know it had not been doing this on the previous day as I walk be there every day at least 2 times.

Oil pressure gauge stopped working. Entire instrument cluster had to be replaced. $650. Ridiculous.

The driver seat heater randomly turns on by itself. It randomly switches from the seat to the back of the seat to both at the same time, in no particular order. When I turn it off it just comes right back on again. I had the module in the door replaced one time, but it still does it. I live in the South, so it's extremely unbearable during the summer months. I will go for weeks at a time when it doesn't do it, but then it just seems to start again. There really does not seem to be anything in particular that triggers it. I thought maybe it was getting wet when it rains, but since I live in the South we have high humidity 95% of the time, so we have moisture problems here all the time. I can go for weeks that it doesn't happen, then it just starts up again. I have searched the problem on google and found that other people complain about the same problem with this particular model, but I can not find a safety recall issued by GMC.

Speedometer stops working and goes below the O mph. This happens every day after around 15 miles or so of driving.

- the contact owns a 2005 GMC Sierra hybrid truck. Two weeks ago while driving at 5 mph the vehicle's steering wheel and the brakes locked. The contact was able to drift to a stop. The vehicle also vibrated, and made a whistling sound. After several attempts the contact was able to restart the vehicle. The vehicle's lost power at red lights; however, it restarted. The dealer stated that they did not have the parts to repair the vehicle, they were also waiting for a technician to diagnose the vehicle. The vehicle has been at the dealere for three weeks. The dealer also stated they didn't know where the parts were coming from, yet they've ordered the parts. The contact was currently renting a vehicle. There were no warning indicator lights present at the time of the incident. Two weeks prior to the failure, the contact's vehicle overheated and the warning indicator light appeared. The dealer replaced the water pump. The contact also spoke to GM and was told they would investigate the dealer. The contact thought there was a failure with the battery, it was defective and serviced under the warranty.
