chrysler claims that only like 1.5 percent are experiancing problems with the heads on these 3.6 pentastar motors and it is due to bad gas and certain driving habits? sounds like a load of you know what to me. they know whats causing it. is 1.5 percent about the amount of people that buy jeeps and acually use them like a jeep is intended to be used. i wonder how much the over heating can be attributed to people changing their tire size and offroading with that rediculous 3.21 gear they are throwing in alot of these jeeps? that would be an intresting stat i would like to see. they are gearing to many of them for soccer moms and not offroading. i don't care how much more power the 3.6 makes, that is a crazy steap gear for a 4x4.
