I bought this 08 Chevy Trailblazer new 9-30-08.from the date I bought it I noticed the charging hand on the instrument panel shows the battery not charging about 50% of the time, the owners manual says this is a fuel saving feature.when the battery is fully charged the alternator quits charging.after approximately 1 month of driving this veh.I noticed when it quit fully charging the power windows would not roll but 1/3rd of the way up, the veh.can't be driven in the rain due to the wipers barely moving, the bose stereo system loses power and malfunctions, and im sure other things don't function properly, the transmission malfunctions and wont shift like it is designed to do, the miles per gallon gauge resets itself while the veh.is moving. I have had the veh.to the local Chevy dealer and they don't have a clue to why it is doing this, I think if your driving on a major highway and run into a hard rainstorm you would be lucky to get off the highway before causing a major accident due to the wipers not working properly, ,I experienced the situation once but was lucky traffic was light. Am taking the veh.to another dealer this week to see if they can fix the problem. The wipers not working properly is an extremely dangerous problem.
