I purchased a brand new trailblazer on January 25th. On January 27th on the way home from NJ the transmission went out leaving me stranded on the turnpike. The car has 307 miles. Needless to say I am not sure what to do. It’s currently in TomsRiver NJ at dealership. Not too confident that even with a replacement the same thing will happen again. I’m tempted to exercise the 7 day return policy.
