Faults:

3000 miles had a main seal leak, took to original dealer.. fixed it. Since then, it has had 3 new clutches (I have owned nothing but manual transmission for 35 years.. not an issue of don't know how to clutch or shift). Had an electrical problem, 5 different times in the shop for fuel system issues.. and not the notorious booster pump issues, blew out front tire at 12,000 miles, rear blew out at 18,000.. and I mean blew.. like ripped.. no warranty on the tires. The topper? need a new trasmission... it also has a fuel leak and an antifreeze leak somewhere... a piece? ya I would say so. I bought this truck because I was so totally pleased with my 1994.. still have it. Same truck, except the 94 is a crew cab.. repairs on it in 170,000 miles? 2 sets of brakes.. yep that is it.. my 94 hauls anything, the 99? put a trailer behind it and empty you would think you are pulling a train. The dealer here does not help either.. every warranty repair had to call GM corporate to get them the dealer to "admit" it was warranty.. bye GM...

Faults:

Power window went out, still under warranty at the time. Think the power window unit was replaced with another faulty unit, still doesn't work right.

Lights and gadgets always going off on dash, like security coming on when driving, no 2WD light comes on, says check 4WD soon, check engine soon, check this and that and whatever.

Sometimes doesn't want to start, have to keep cranking it over until it feels like starting.

General Comments:

Nice truck except for the problems. GMC needs to seriously look at improving these problems. I figure I will really have to be sinking some money into it soon and I really don't put that many miles on it, considering I bought it new in 1999 and only have 52000 on it. I figure the 4WD will be going out and whatever the problem with it not wanting to start every once in awhile will be salty. I wonder if any others have that problem with it starting?

Whatever, I am not buying another GMC.

General Comments:

I am not at all happy with my truck and the way the dealerships treated me.

Faults:

30,300 miles. Just out of warranty and stopped running. Anti freeze was leaking into the oil from the manifold and ruining the oil.

No evidence of this on dipstick or when oil was changed so presumably Dex-cool doesn't do the white scum routine.

34,000 miles. Anti lock brake pump will not shut off. Removed fuse. Came here for help.

General Comments:

Believe the dealer charged me and GM for manifold repair. Dealer mechanics had failed to connect fuel lines or coolant hoses at first pick up resulting in car being towed back to dealership for 2 additional days. Dealer overfilled oil by quart and a half, overtightened drain plug, and <humor> added a flanged bolt stud to rear tire </humor>

This experience far exceeds my previous "good story" collection in a negative sense. I have often noticed people and organizations adopt labels opposite of what they are. In this case it appears true. I reverse the good and professional to describe the service.
