We have had several problems with this vehicle. We've had tires replaced twice, rotors, and brakes resurfaced, and rear-end dropped so the springs could be adjusted. But the biggest problem has been with the roaring in the motor. The dealership has had the vehicle for more than 20 days on and off looking for this noise. I've had it to them 8 times or so trying to find it. The noise didn't start until around 3,000 miles, and gets worse and easier to duplicate with more miles. The first 7 visits they said they didn't know what it was and was clueless to it, but the last visit, and 4 days of it, they and GM decided it was a "characteristic" of the vehicle, and nothing could be done. On the otherhand, one mechanic says it's coming from the drivetrain, but others say it's an improper balance in the motor. Either way I'm paying too much money for whatever it is!

After only one month of purchase auto start feature does not work unless you were 3 feet away. The vehicle once sat over night would make a really loud clattering sound when you would turn on the engine. I took the car into the dealer and told them about the problems the dealer indicated that they had to reprogram the software in the Tahoe to reprogram auto start. The next morning I was called and informed that they were unable to reproduce the clattering sound and that nothing wrong was detected with the vehicle so that it was ready for pick up. Everything was O.K. for about a couple of months. Auto start wasn't working again. At my third service visit to the dealer I noticed the tires were starting to get wasted towards the inside. The vehicle only had about 5,000 miles on it at the time. When the dealer was informed he indicated that the tires needed to be rotated. After about three tire rotations I noticed the tires getting warn out pretty badly on the inside. He indicated that the problem could be that it needs a front end allingnment only after the vehicle having less than 12,000 miles. The front end alignment was done on the vehicle.to this day that the tires are wasted more on the insides than the outsides.this last month we have had a problem again with the loud clattering sound in the engine when we start the vehicle.it has gotten alot worse I took it into the dealer and they said that they were aware of the problem and that it appears to be oil build up in the air compressor that when it sits for more thatn 3 hours it apparently makes this loud sound when you start the engine. He indicated that Chevy is looking into the problem and to this day has not done anything about the problem.I was furious when they refused to do anything about a problem that Chevy well knows is a manufacturer defect.

The contact owns a 2007 Chevrolet Tahoe. While driving 25 mph, each door on the vehicle made cracking noises when decelerating or driving on jagged roads. The dealer stated that the failure was unrecognizable and informed the contact to take the vehicle to a mechanic. The mechanic applied lubricant to correct the failure, but the noises returned. The current mileage was 18,000 and failure mileage was 320. The consumer stated did have tire problem, tires were cracking and coming apart. The dealer replaced all 4 tires. Updated 09/19/07

: the contact stated while traveling 45 mph, the vehicle's rear passenger tire drove over a nail and lost air pressure. Upon inspection, it was noticed that a dime size piece of rubber was missing along the middle of the tread. The vehicle was driven to a tire repair shop, who replaced the defective tire with a full size spare. The contact did not notice any vibration while driving prior to the incident. The tire manufacturer was contacted, and determined that the contact could have hit an object on the road, causing the tread separation. The service dealer was contacted, and provided no assistance. The contact expressed that the vehicle was not safe to drive, if a piece of tire ripped off so easily. The tire was a Bridgestone dueler 684, size: P265/70R17.
