“I have a 2003 s-10 with 28,000 miles. I have had to replace both co2 sensors and now it won't start. It just started jerking and the fuel pump and filter work fine. Its getting gas and has a new battery. The check engine light is on. It wants to start but it doesn't. Also the radio comes on when I turn it off. What gives? This is my 3rd s-10....”
NHTSA complaint #10263928, filed 2009-04, 28,000 miles“This has just started in the last two months. I have had the truck since it was new. When I try to put gas in my 2003 Chevrolet s-10 the gas pump nozzle will keep clicking off no matter how slow I pump the gas in. The last two times I put gas in it, it will overflow even if the tank is empty. I take the nozzle out of the tank and the gas will continue to bubble out. I took it to our mechanic and he looked it over and could find nothing wrong.”
NHTSA complaint #10095983, filed 2004-10, 53,000 miles“Evap hose on fuel tank chewed up by rodent , when 1st had truck in shop was told hat service engine light came on because fuel cap was not tight,have a friend that works at another car dealer and have had them clear code for gas cap,when brought to Chevrolet dealer last time they do a smoke test and tell me the evap hose was chewed up by some kind of rodent and thet it would cost me $1500.00 to fix or my truck would never pass emisions this is not covered by warranty.”
NHTSA complaint #10110643, filed 2005-02, 600 miles“I couldn't get gas into it the vehicle. I took it to my repairman. Which cost 169.38 to replace the gas filler neck. I called GM and was told if I had taken it to their authorized dealer they may have considered reimbursing me. They said if a recall comes up I can file to get my money back. Meanwhile this truck is a 2003 with only 37000 on it. Only 3 years old. I saw on your site that other people have had the same problem I had and filed a complaint. So if they hadn't paid for it to get fixed I would off had a bigger bill from a dealership.”
NHTSA complaint #10177197, filed 2006-12, 37,000 miles“I purchased a model 2003 Chevrolet S10 crew cab in december of 2002. Sometimes when I fill the tank it overflows, runs down the side of the truck and makes a spot of gasoline on the ground. It has overflowed many times since I bought the truck, using both the highest and lowest fill settings on the fuel pump nozzle. The dealership replaced the fuel tank, vent lines, charcoal canister, and other parts. The Chevrolet regional service manager said that Chevrolet will not do any more work on the truck. …”
