Speedometer in 2003 GMC Yukon acting erratically. Inaccurate reporting of speed on speedomoter. Truck shows 50 mph when stopped. This is very unsafe and cant be trusted. I have read on the internet where there are numerous complaints. GMC needs to issue a recall on this issue.
Arrived home one evening and noticed my speedometer was reading 43 mph while sitting still in the driveway. At first it was accurate by subtracting the error to calculate the speed but has subsequently become erratic in it's inaccuracy to the point of total unreliability. I fear the consequences relating to not being able to determine the speed, such as traffic tickets and such. It is a safety issue as well as I travel through numerous school zones in my daily travels. It remains unrepaired and will be so since I don't have $500 laying around to replace a defective speedometer. Upon searching the internet I was surprised to find there are many, many others who have this identical problem, which tells me there is a defective design, and as such I believe this issue should be resolved with the owners of these vehicles by general motors corp.
My speedometer has been sticking. Sometimes it resets sometimes it doesn't. Recently it has been stuck past the 120 mph. Repair shops recommend taking it to the dealer for service but have not done so yet. This has been happening off and on for at least 4 months.

I have taken my 2003 GMC Yukon xl in for service on the air conditioner on more than one occasion. I recently moved from michigan to tennessee and while living in michigan I notices a squealing noise whenever I turned on my ac. The noise would last a few minutes and then stop. I also noticed a rattling noise upon acceleration while the ac was on. I took it to the dealer in michigan and at first nothing was found. I again took it to a dealership in tennessee and was told that it was a recycling switch, and it was replaced. Now, almost I year later the same problem has occurred but unfortunately, my vehicle is now out of warranty (50,000 miles) and I am now told that the air compressor has completely failed. It will now cost me over $1,000 to repair on a car that is less than two years old.
