2004 Chevrolet Avalanche 2500 problems

Filed Nov 26, 2015 · Brakes · 68,000 miles · IL

Brake line failure. I was approaching a stop sign and applied the brakes. The pedal went to the floor and the ABS activated and I was not slowing. There was no cross traffic so I luckily avoided an accident. The brake line failed due to rust. Braking ability with only the rear brakes active was virtually nonexistent and there was no warnings on the display. I do not understand how the previous investigation into gm brake lines was dismissed.

While driving down the road with the A/C on suddenly the drivers side starts blowing hot air while the passenger side is still blowing cold air. If I put the avalanche into neutral turn off the engine and re start the engine it will suddenly start blowing cold air again - it is happening quite a bit more frequently and I have read on some avalanche forums others have had this issue as well. When its 100+ degrees outside the air needs to work the heater I can do without during this time.

Poor breaking at 8500 miles. Dealer turned front rotors. Poor breaking again at 9500 miles, dealer replaced rear pads and rotors. Breaking almost caused serious accident, as stopping distance was about 3 times normal. Gm would not cover 2nd repair. Front pads were still good, and truck driven gently about 200 miles per month. I believe inferior steel used in manufacture, and all should be recalled.
