The battery went dead when the truck was only 2 years old, but it was easily replaced.
This Blazer was bought as a family car that would be safe, have decent gas mileage, enough power to merge on a busy highway, creature comforts and at a fair price. It is still accomplishing these goals.
The only thing we would add would be a 3rd row seat since the blazer can easily handle 4 people or 5 in a squeeze.
If you add a third row of seats it completely defeats the purpose of a mid-size SUV. If you did how much room would that actually leave you to move.
