Example complaints

Brakes: “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.”

NHTSA complaint #10807079, filed 2015-11, 68,000 miles

Electrical system: “Speedo at 60 miles per hour when stopped. Increases from there when moving. Can not tell correct speed. Appears to be a common problem with 03 to 06 chevy vehicles. Warranty up on vehicle due to age not miles. Dealer says cost is over $500.”

NHTSA complaint #10196027, filed 2007-07, 30,842 miles

Other or unknown: “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.”
