I own a 2003 Chevy Trailblazer which I have been having a problem with since 3 months after I bought it. At first my speedometer would stick and flutter. Unfortunatly it didn't happen consistantly enough where the dealer could diagnosis it. At the begining of this year the gas gauge quit working all together, I took it to the dealer and they stated it was a cluster problem. Over $500 to fix. I am aware that there is a extended waranty being offered to Silverado, Tahoe, Avalanche and Suburban owners on their clusters for this exact problem. Chevy states they have not received enough complaints to include Trailblazer- is anyone else having this problem? Any suggestions on how to best get the word out?
