2003 GMC Sierra 2500 hd ext. Cab, 8-ft. Box. In cooler weather, fall, winter, spring, the gauges malfunction. That is, the speedo and tach read wildly high or don't activate at all, and the other gauges all are non functional. This is intermittent and is apparent when starting on cold mornings. So far, symptoms have disappeared in warmer temps. It has occurred every year. There is an advisory, but GMC won't act on my word, must see it.
The speedometer and tachometer works sometimes but other times it does not work. This is a safety issue as the speed is unknown. The vehicle was taken to the dealer but I was told that it is no longer under warranty.
At around 102k miles, speedometer needle quit returning to zero when the vehicle stops moving. Needle may come to rest at any point on the dial when vehicle is stopped, and the rest point may or may not change while the vehicle is underway, making it difficult to estimate speed (e. G. , needle may initially indicate 30 mph at rest, but actual speed underway isn't necessarily 30 mph less than indicated because the rest point may have changed). And when the dial zeros at 120 mph, the truck effectively has no speedometer at all rather than just an inaccurate one. I received a letter from gm warning of potential instrument failures and offering free repair on vehicles with less than 70k miles; an email correspondence with gm confirmed that they would not repair mine for free or at reduced cost. Internet discussions and ads for instrument repairs reveal this to be a common problem on a range of '03-'06 gm vehicles. The gm dealer I called will fix the instrument cluster for $500 -- roughly 3 times what repair services advertising on the internet charge to replace all the defective stepper motors in the cluster. This problem is certainly safety-related (think of misjudging speed in a rollover-prone vehicle going into a sharp curve), and to the degree that is virtually inevitable on certain vehicles, gm should issue a recall rather than a limited "secret warranty".
Speedometer reads high & low no relation to actual speed. Constant problem. Excessive cost to repair using hand held gps for now. 2003 GMC 2500 sierra hd 4x4.
Speedometer in my 2003 GMC sierra has gone erratic. Zero to 120 mph fluctuations, sticks.
Speedometer doesn't read correct speed. Speedometer needle sticks and then when you start again it will start reading from where it was stopped so if it sticks at 30 mph and you resume speed to 60 mph it will read 90 mph.
