Are the Chrysler 3.5 V6 engines any good. Like the ones in the 2010 dodge chargers? Do they have a bad reputation as far as durability, failure, or other concerns ?
They suck. Useless. Underpowered gas hogs. Stupid design. SOHC with a giant timing belt that has to come off to do the water pump. Basically doing any job on those is a hassle. Takes up a ton of room. They did not fare well with less than religious maintenance.
The newer 3.6 is much better but it's a totally different design. Even the 3.7s were better too as well as any pushrod V6 produced in the last 25 years.
