Problems with 2004 GMC Sierra 1500 EQUIPMENT

I have a 2004 gmc sierra 1500. i am having several problems with the instrument panel, speedometer not reading properly, temp gauge wrong readings. the dealers want $750.00 to repair if the vehicle is over 75,000 miles. they have said they sent recall information for this problem, i have never received anything of the sort. for a vehicle i paid 32, 000 for i find this to be unsat. gmc needs to fix this problem free of charge for there customers, i would expect this treatment from a ford dealer. *tr

In my 2004 gmc sierra the wiring harness for the a/c down near the passenger floorboard smokes and i smell burning plastic and my a/c doesn't work and i talked to a few other gmc and chevy owners and they have the same problem. so if alot of people are having the same problem i think its something to look into... *tr

Reduced engine power, this has happened about 7 times. when this happens the engine shuts down to 1500 rpms maximum. took to dealer, they told me that it was the throttle body valve and actuator assembly. this part was replaced at a cost of $481. within two weeks the same problem has happened twice more. this is dangerous when traveling in traffic. *tr

Since the purchase of my vehicle, there have been multiple issues with the vehicle 7-8 issues, one selling point was the onsatr cellular service, never worked, etc. etc. etc. the salient matter at this time is that the drive train orginally exhibited a clincking sound shifting from 2nd-3rd and from 3rd-2nd, the noise was sporadic and went from a clincking to a decirnable clunk all the time, the dealer has attempted multiple repairs and now states the matter is a concern but it is not a problem, the oem, gmc, has states that ther is nothing they can do, the problem is getting worse and i am running out of options, i can not sell it as is. *jb
