i would get a lawyer . i have called isuzu to complain and they told me it sounds like a dealer problem.
and as far as the shocks. i have said it before and will say it again the stock shocks are junk. they cannot handle the cold or the salt or maybe its both. i have just over 50,000 miles and have had the front shocks replaced twice under warranty. the rears replaced once .i just installed rancho 9000's and found one of the fronts bad again. shawn
