Traveling from texas to florida, vehicle began stalling. At times the vehicle wouldn't shift out of lower gears, at times it wouldn't start, at times it would shut off. Found dealer in florida that changed out a wiring harness in the steering column. The vehicle had less than 30,000 miles at this point. Have also had to have the engine replaced at 50,000 miles. Dealer couldn't figure out why the engine wouldn't work, nor could the dealership repair. Replaced with a new engine and is currently at 30,000 on new engine and problems starting again. This vehicle does not tow or drive off road at any time, there is a defect in this product that needs to be addressed.

2002 chevy avalanche, 5.3l engine seized up on me as I was driving and could have caused an accident as I lost power. I'm not getting any satisfaction from gm or the dealer as to why this happened. I just want a new engine. Can you help?

I bought a new avalanche in october, 2002. It has been losing one quart of oil per 1000 miles. Chevrolet says this is normal????? They replaced the pcv valve, but said it will still burn 1 quart per 2000 - 3000 miles. This is absurd for a new engine. What effect will this have on engine longevity? Catalytic converter? Air pollution? I don't remember this feature in the advertising or sales pitch. What is the federal safety agency doing about this known defect?
