First time poster, long time GMC customer. 2015 Yukon Denali XL 63,000 miles 4wd. Got in the vehicle to take my family out to dinner on July 10th, 2017. Less than .5 a mile after driving I noticed the idle wasn't right and felt a slight shudder. I slowed down and looked for a place to pull over...

This is driving me nuts. My 2000 GMC Jimmy 4.3 2 door, James as we call him, has been sputtering for about 6 months now and I have run out of ideas as to why. Its not all of the time but at least 75%. I have replaced the distributor, rotor cap, spark plugs, serp belt, fuel pump, temp control...

I've been looking at buying a new vehicle. I'm looking mostly at 2010 Chevy Suburban and '10 Cadillac EXT's. My father owns a 2008 GMC Sierra Denali and for the ease of it I have been considering buying his truck. In my research I've read a little bit about that engine having some issues...

Hello. I just bought a 1996 GMC Jimmy with a few issues. Since I'm not rolling in cash I'm hoping to manage some of the repairs myself. First out of the gate is the temperature problem that I didn't notice a couple days ago. The Jimmy starts smoothly and there are no strange noises coming...

my beautiful sonoma just died today while accelerating on the highway. it started knocking like crazy and there was not a single drip of oil left in it (it was full to the line when I checked this morning). I bought the truck 5 days ago for 1900$. I sure am gonna get some kind of refund from...

Hello! I have a 2000 Sierra with 250000 KM's on it. Last winter I had no oil pressure and cream color engine oil. I brought it to a shop and they ended up tearing down the engine to get to the head gasket and heads. What they found was the heads were warped. So they got them milled down...
