[QUOTE="svtfocus2cobra, post: 16454436, member: 21786"] FCA motors have major issues with the valvetrain in general. The 3V Ford cam phaser issue can be prevented by using the correct filter and good oil and changing your oil on the dot every interval. The other Jeep that bit us in the ass is a 3.2 V6 from a Cherokee. They have a common issue that causes the roller to damage the camshaft lobes in which it really tears into the cam and it starts as a ticking. The debris that comes off of there clogs up the passageways, and like it did to us, it seized the camshafts causing all 4 VVT sprockets to snap in half while damaging the new camshaft in the process. The customer brought the car into us before this happened so we installed new heads and everything and while on the test drive I guess a piece of debris from before got sucked up into the oil passage and caused the camshaft to seize from oil starvation. We are in the process of fixing that one now which was just an unlucky chance occurrence that it happened to us. Other common issues with FCA vehicles: The 3.6 V6 in the Durango and G Cherokee both have condensers that also contain the transmission oil cooler and those like to leak causing transmissions to be damaged. The Durangos also have an alternator issue that is a recall, but they like to burn up and catch fire when the vehicle isn't even running. We had this happen to us with a customer and it ended up frying his PCM and it's looking like it did more than that possibly. I've replaced the PCM in his Durango twice now and he is still experiencing the fans being run at 100% duty cycle all the time. It states that the PCM is sending the command so it must be the PCM but because we have replaced it and it is still occurring then it has to be something else. We'll get it to act normal but then it goes right back to 100% and it sounds like a 747 taking off everywhere you drive it lol. It's issues like that that we only see with FCA vehicles. A lot of them start as regular issues that most cars see at some point, but with FCA they turn into complete nightmares. We've lost tons of money on them due to just unforseen circumstances. I've talked to dealers and other shops and they say the same thing. [/QUOTE]
