2006 Chevrolet TrailBlazer LS 4dr SUV (4.2L 6cyl 4A)
I purchased a new 2006 chevy trailblazer 4dr ls 6 cyl in 2005. As soon as the warranty is up my check engine lite came on and then went out, and they tell me that I have a miss fire in the head of the engine. I took it into a dealership and they tell me that it will cost me $4,000. for a new head that they wont stand behind because it is not a recall yet. The service writer tells me that they are having this problem in the Colorados too. And that it is a manufacture flaw that the heads they used need new sleeves. In the mid year of 2006 they changed their warranty to a 5 year 100,000 . I have the 3yr 36,000. My blazer has just under 50k miles.
