general problems of the 2008 GMC Sierra

Airbag service light and message appeared. Defective 15297468 sensor caused system failure. Part badly damaged by corrosion.

The lower steering shaft is making a noise. Took to a repair center and show the shat needs to be lubed it makes a creaking noise when driving over humps and also the slip yoke in the rear of the truck when coming to a stopped position the drive haft moves and back and it feels as if you was being bumped from the rear of the vehicle. The two issues are found all over the web reporting these issues and GMC as not identified or resolved these issues especially on these models.

On the morning of April 11 we had a severe thunderstom at approx. 3:00am. Later in the morning at approximately 6:30am I found my 2008 Sierra truck running in my garage with the garage doors shut. The headlights were flashing and the garage was extremely hot due to the engine running. There was a lot of water condensation on the floor indicating that the engine had been running for quite some time. The temperature guage was at running temperature. My keys were in the ignition so I opened the garage to air out the carbon monoxide and took my wife's keys and tried to stop it remotely but it would not stop. A few minutes later I went outside and came in thru the garage door trying not to breath the fumes. By then the truck was not runnung. I found the check engine light on. When I touched the key in the ignition the check engine light went out. The seat presets were messed up and the clock was several hours off. There was absolutely no way the truck was remote started. Even if it was it should only run for 10 minutes. This was a very serious and dangerous situation! continuing on with a similar situation a year ago, there was a severe thunderstorm coming thru. Our neighbors had come to our house during the warning since we had a basement. We were all standing in the garage with the garage door open and our 2010 GMC yukon started up like someone turned on the ignition. There were no keys in the ignition. The electrical storm was on-going when this happened. We saw our neighbor leave in her yukon so we thoguht maybe she remote started hers so I followed up with her to see if she had remoted started her car and she had not. She tried to remote start her car and it did not affect ours whatsoever. It appears that both incidents seem to be storm related. It is a very serious and dangerous situation knowing this could happen while we were asleep or away for a few days.

The drivers side interior door handle will not open the drivers side door. The window has to be rolled down in order to open the door from the outside. . . . Based on the GMC forums I have read this happens to a lot of people. The replacement costs can run from $200-$800 due to plastic pieces and cables being used that melt and break easily. This is very dangerous because if someone were to ever get into an accident and they need to get out of the vehicle quickly they will not be able to open the driver side door if that is the only option to be able to get out. They will have to kick the window out in order to open the door with the outside handle. I am the original owner of the truck and am very disappointed this has appended at such a low mileage.
