“Well,when driving my 2002 chevy avalanche truck the reduce engine light cuts on. In addition, my truck starts to slow down and reduce speed. Sometimes on the interstate while I'm driving also. I've been to two GM dealership and paid money to have it service. As a result, they were charging me a lot of money, but never fixing the problem. It's very dangerous when driving sometime, so I been pulling over and resetting the computer to drive. I've read that there's recalls on some GM truck like mines. Also, I brought it to the GM service department too.”
