One problem related to engine noise has been reported for the 2002 Chevrolet Blazer. The most recently reported issues are listed below.
Noticed noise; have taken to dealers 8 times and they can not fine the cause of noise; now gm representive anthony teta says it is inherit design problem; rox covert told me he would fix it, replace it or give me my money back - pickup it up 5/20 and because it didn't make the sound returned to me. I do not want to put up with this noise, I'm tired of the run around, and very disappointed with my first new vehicle purchase that covert, Chevrolet or GMC will not try to right this problemed vehicle. Please help me if you can.
