1999 GMC Sierra SL from North America - Comments

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.

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.

Appears, like many of the reviews that the dealers are plainly at fault, one way or another.

I have not read a consistent complaint about this vehicle except for the handles and door latches being of poor quality.

I feel your pain. I couldnt tell you the amount of time I have spent with my 1999 GMC Sierra in the shop. I had the anti-freeze problem as well, but mine happened under warranty.

Well I see I'm not alone. Dealer always laughed, and said "that's a common problem". GMC CUSTOMER SERVICE acted like my truck was the only one, and for me to talk to the dealer.

I have had the ABS problem too. What did you do to fix it?

It's the dealer's fault.

The dealer seems to be at fault.

I have had no problems with my 1999 Sierra that I could not fix myself.

I currently have 110,000 miles with no problems that I feel are out of line for a new style truck.

Please remember this is a new frame, engine, and body (as of 1999 model year). Unless you buy from someone who has kept up with recalls and technical service bulletins), buy a 2000 or newer truck. Most of the new-car bugs were worked out in the first year.
