After disengaging cruise control my speedometer was registering 80mph plus as my speed. when coming to a stop the speedometer registered 35 mph. the speedometer went up to 100mpg when i stayed with expressway traffic, keeps on going up,even though my foot is off the gas pedal. this is a defect in the dash instrument cluster.(as told by gm repair person) i was not notified of a recall because there isn't one. *tr
I own a 2004 chevrolet silverado 3500. the speedometer and other gauges do not work properly. for example, the speedometer reads that i am doing 120 mph. keep in mind i haven't even released the brake pedal yet. there is also an issue with the amperage gage. i have received a letter from chevrolet extending the warranty, but of course even with the extension, it is still out of warranty. this is a huge safety issue. if the speedometer is reading 120 mph while sitting still, how do i know that when it says i am doing 55 mph that i'm not actually doing 120 mph. this is a defective part that gm manufactured. looking at the internet, this affects pretty much all of the large gm trucks. i when to check the cost for replacement of this part and they wanted $450 just for a refurbished cluster. this is an on going problem and the corporation is giving out defective parts with out regard to the safety of the people driving the vehicles or anyone around them. an odd thing that i have noticed is that if i let the fuel to deplete completely, then fill it up, it will reset the speedometer the second fill up. i have tested this several times and it seems to reset it at least by the second time. if i do not deplete the fuel take it never gets below 40 an the speedometer. this un-scientific test has not affected the amp meter being bad though. this is continually happening. *tr
