What 2002 Chevrolet Avalanche 2500 owners say
Engine & cooling all 31 →
2002 Chevy Avalanche 2500 with 8.1 engine dies without warning at driving speeds. The battery light comes on, after the vehicle shuts down, but no check engine light and no warning whatsoever. The vehicle just shuts down. When this happens there is no power steering and no brakes for this 7000 pound vehicle. Sometimes, once pulled over and shutting everything off and trying to restart it will restart, sometimes taking up to 10 minutes of trying to crank it intermittently before it will restart. It has done this, off and on, at random intervals over the years I have owned it. I have read on the internet others from who have the same problem and most likely solution seems to be the crankshaft position sensor which some say has been recalled on the 2001 model engine for the silverados, but cannot find anything for the same 2002 engine, which is the same engine. …
4 times now my vehicle has stalled with no warning or any indication of anything wrong with the vehicle I.e. Warning codes, lights, or symbols. There has always been plenty of fuel in the tank. It happened to me this morning on the way to work traveling at about 65 MPH after finishing a curve in the road. The engine died for about 2-3 seconds and then it restarted by itself. The other day my daughter and I were coming back from the dr. And I had just made a left hand turn from one busy road to another and it completely stalled on me. I had to stop in afternoon traffic and after about a minute and completely turning the key off and putting it into park it finally started. I talked to the service writer at quality Chevy and he told me that many of the same trucks have been coming in and having the crank position sensor replaced. …
Brakes
The Avalanche is our tow vehicle (only) which is why it has so few miles for a 2002 model year vehicle. Normally it is towing a 9000 pound 28 foot toy hauler, but just by pure luck it was towing a single axle flat bed trailer with the cab for a 1935 Chevrolet pickup on it back from the body shop. I pulled into the driveway and tried to stop and there were no brakes. Tried to apply the parking brakes and the cable snapped. Stopped by driving up a hill into the grass. Took the Avalanche to the dealer where they told me the brake lines all had to be replaced and they were no longer available from the manufacturer. In the course of getting the brake lines out they found that the fuel lines were also leaking and had to be replaced. The total bill for repair was $2900.00, plus the vehicle was out of service for 6 weeks. …
Saturday January 23, 2016 during a snow storm my 2002 Chevy Avalanche 2500 VIN# [redacted] lost all brake control due to failed and corroded brake line under driver side door at retainer clip on side of frame without any warning signs of soft pedal or intermittent braking. This is the second truck driven a 2004 1500 with the same failed line in same place on frame. Just before the brake line failed there was a small car in front of me with two small children in the back seat that turned right if they came to a full stop I would have not been able to negotiate around them that could have resulted in injury and or death of the other occupants in the car. I do think that this is a big safety concern for all not just drivers of the affected trucks but anyone or object in its path. …
Electrical system
2002 Chevy Avalanche 2500 with 8.1 engine dies without warning at driving speed. The battery light comes on, after the vehicle shuts down, but no check engine light, no problems with alternator or battery charge. No sputtering or sluggishness, no warning whatsoever. The vehicle just shuts down. When this happens there is no power steering and no brakes for this 7K pound vehicle! Sometimes, once pulled over and shutting everything off and trying to restart it will restart immediately, sometimes it takes up to 10 minutes of trying to crank it intermittently before it will restart. …
Engine died while driving 60 MPH on the interstate in snowy conditions on 2 lane portion in heavy traffic. By the time I coasted to a stop with no power steering or power brakes I was on an overpass with nowhere to pull out of traffic, so ended up blocking one lane of traffic for about 2 minutes. OBD ii code reader showed no code errors. Replaced fuel filter. Did not fix problem. After checking NHTSA site as well as others on the internet found it might be the ckp (crankshaft position sensor). Took it to dealership where their diagnostic tool verified it was the ckp. Quoted part and labor to be $300 - $500. Saving up money for repair.
