Beware of the ignition steering column Gremlin, while getting lined up to tow a 16 ft cargo open 3ft trailer. The truck started having a problem that only happened the day before...the ignition key was turned but the electrical was flickering wildly then dead then start...I had to move a trailer with personal belongings or lose them to the DUMP. I had yet to hook up to the trailer, when the truck just lost complete power in reverse. I restarted the truck, and as I backed up power failed, I was trying to turn the wheel because the column was locked, and I needed to returned the Gear to park so I could start it, and the key was stuck in the now locked ignition. Only it would not start, as soon as I just gave up trying to turn the engine over, the truck starter kicked on and kept grinding, the truck was in park, steering still locked, I put the gear in Reverse and the truck took off Forward with the steering locked to wards a retaining wall...emergency brake full 3 feet pressing the pedal the truck was still head to the wall to the right, key would not turn but came out of the column. I held on as the truck in reverse reved up forward, I pulled on the steering wheel left breaking off the turn signal arm in the process...the truck hit the wall; and just flicked and shut down .

My parents were driving N on I95 this weekend from FL to VA. The truck's door locks went up & down; the lights flashed on & off; and then, the truck's operating system shut down. The engine, power steering, power brakes nor anything else did not work. Couldn't steer the truck & barely able to stop from 70 mph. 300 miles later, it happened again. Fearing for their lives, they did not stop the rest of the way home. When they took it to the dealer, he said that the "positive post" had come "loose". This did not seem reasonable & far-fetched to my father since he had observed the battery posts that week himself. Is this another cover-up by GMC when more lives are at stake?
Drum brakes! List price 38k + and I got drum brake on the rear-end. Maybe they wouldn't need all those air bags to get the 5 star safety rating if the truck could stop. Put disc brake all the way around.
Bought the truck in Sept. and I gotta say, this is one smooth driving pickup. If I had the extra dough, the SLT would have been the way to go. The door handles are in a bad spot, passengers have a hard time finding them. The cab is already starting to make noise and the steering feels REAL cheap, I'm planning on bring it to the dealer to have it checked out. Fuel economy is good, averaging around 17 mpg. The 5.3 liter has great power, with the truck loaded up, but I haven't towed anything heavy yet so I'm not sure how the truck would handle or brake. The leather interior is very comfortable, even on long trips and you can't beat the full size room. Got a good deal and dealership was great.
