Problem Description and Possible Solution
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.
Average mileage: 94,085 (120–183,571)

The entire dash cluster is dead at this point, but it started with the speedometer, then the tachometer. The entire cluster died at 243,000. It is amid other problems as well mainly involving electrical components.
My speedometer, engine temp and shift light stopped working all at the same time. Also, my seatbelt light kept blinking even when the seatbuckle was connected.
seedometer is stuck all the way to right and will not move.
Fuel and volt gauge don't work
Half of my instrument panel and half of air conditioning fan is out
Complete failure of gauge cluster and display panel...Devoe GMC in Naples fixed it under extended warranty promptly and without issue...very pleased
First the speedometer would settle at 0 when the truck was stopped... And work its way up to beyond 120 mph at moderate speeds. About a week later, the water temperature gauge went haywire and read only between high and very high (and settled at above normal range when the truck wasn't running). In reading blogs online, I discovered a guy on Ebay from Minnesota who repairs these clusters for about $60... And has lots of positive reviews. I'm mailing mine off to him this week. By the way, removing the cluster is a pretty easy job... You can find a youtube video that shows the process that is excellent.
intermittent issue; the whole dash goes dead a few min at a time. if so many people have the same dangerous problem why doesn't GMC have a recall? That's what's wrong with this country nobody will own up to mistakes.
Temp. guage and amp not working also tac. not working all the time
first the oil pressure then the speedo and now the gas gauge all within the last year
Gauges work intermittently - no solution yet
All the gauges wouldn't work after I started the truck....Drove a short distance and parked the truck...About two hours later I started the truck and all gauges worked properly....Hasn't happened again so far...34000 miles now...!!!
speedometer and tachometer read incorrectly and erratically if at all. Had it replaced last year at a shop and still having same issues just 8 months later.
Replaced with aftermarket
The speedometer would pulse about 5 or 6 times on a row when I opened any of the doors. If you waited it would pulse again and until I closed the door. As of right now it's at the dealership. They have not found the problem.
all gauges quit working seat belt light blinking even when I have seat belt on
First Oil pressure gauge then gas then Tachometer and now Speedometers stopped
