Would like opinions on 2007-2008 H3's with the 3.7 motor. I bought on 06 H3 with the 3.5 motor on Saturday. Was running rough next day with check engine light on... researched the problem bad head. Took the H3 back to dealer on Monday morning, told them to check it out and give me estimate. Estimate for me to pay $1,600 as they did a 50/50 split. I walked out with my trade in and left the H3 there. Would like to get a 2007-2008 with the 3.7 and don't want seroius issues with motor. Are the 3.7 ok, or are they a POS? Any help would be appreciated. Thanks!
