2002 Chevy Avalanche 2500. Engine cut out at 75 mph! has happened more than once! I lost my brakes due to no power assist and almost had to drive off the road...which would've been a real bad seen. Supposedly this is a well known problem with a fault crank position sensor.

Avalanche 4WD 8-cyl

  • Automatic transmission
  • 51,000 miles
I recently purchased a used 2002 Chevrolet Avalanche 2500hd 4X4 with a 8.1 litre engine. The vehicle has approximately 51,000 miles on it. The first problem I noticed was that the engine would crank, but it would not start immediately. The next problem I experienced was that the engine shut off while I was driving it. This resulted in loss of power steering and power brakes, but more importantly, I was not able to maintain the posted 55 mph limit, and I had to Dodge traffic while trying to steer my "dead" vehicle onto the shoulder. The vehicle did restart and I was able to resume as before. This has happened to me at least 4 times. Thus far after 3 trips to the dealer, they have not been able to repeat, diagnose, or repair this problem.

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 NHTSA doing about this known defect"

The engine appears to be consuming oil. At this point, engine loses roughly 1 quart of oil every 2,000 miles. GM has issued a service bulletin to dealers stating that this is within acceptable limits. This is somewhat unsettling as engine could lose too much oil which would of course lead to severe damage. Dealer is currently running a consumption test.
