general problems of the 2007 Chevrolet Avalanche

After washing my 2007 Avalanche the seatbelt on the passenger side exploded and my brakes started to fluctuate and make a spring noise. This all happened as I drove away from the car wash.

1. Vehicle stabilitrak light comes on, all the dash board lights goes on and off, the needles are going wild and then nothing. The vehicle still drives normal. 2. The clock will not keep regular time even when reset many times. 3. The drives side rear speaker will not come on. 4. When using cruise control the vehicle accelerated quickly causing me to think it was out of control, this happen once.

When driving my Avalanche on a highway, as I approached a red light, I pushed my brake and it went to the floor board. I pumped my brakes to stop and I felt a pulsation as I pushed the brake pedal again and I could brake. This happens intermittantly. I have seen complaints about this on the internet. It should be investigated because Chevrolet wants me to pay for this problem.

Own a 2007 Chevrolet Avalanche 5. 3l flex fuel v8 4x4. Recently when starting it, it turned over longer than normal, and then started with rpm gauge still at 0 rpm's. Then put in reverse, and it said stabilitrack is off and needs servicing soon. Truck started moving backwards, and then seemed as if the brakes were applied, wheels simply would not move backwards. Tried to movie it back and forth several times. Thought brakes were applied or transfer case or axle or differential had issues. Then started it again 3 minutes later and everything worked fine and back to normal, except check engine light was on. An hour later, started it again and this time everything was back to normal. Called dealer and they stated they had seen this before, but it most likely won't be under warranty. Odd seeing as how a large number of other people with tahoes/suburbans/avalanches, and other vehicles expressed the same issue online and on forums. . .
