I have had my 2012 Dodge Durango Crew AWD with the 5.7 less than 4 months and have decided the hemi platform is crap. I have been exsperencing engine knocks multiple misfires resulting in the car bucking. I have done research and found its super common for lifter failure resulting in cam lobes being worn down resulting in such misfires. This research has led me to believe that i made a huge mistake getting a dodge. I am embarrassed just to start it around people i know. Im not going to pay 4k+ to fix this ill just take my lost and get out of dodge as soon as possible.

 

Good luck with you next vehicle.

 

Have you done anything to actually diagnose the misfire and noise, other than internet research? There are multiple things that could cause noise and misfires such as spark plugs, coils, vacuum leaks (loose intake air tubing, etc.), and so on. Before deciding you have a significant engine failure and selling your Durango at a loss, you should spend a bit of time confirming the issue is not something simple and inexpensive. Have you checked for diagnostic codes? If you have a misfire code, have you moved plugs and coils around to see if the misfire follows either a plug or a coil?

In another post you suggest that you could have replaced the transfer case shift motor, control module, and other parts for a lot less than the dealer charged, so I assume you are more than capable of checking some of these simple, routine maintenance items.

I am sure there are 10's of thousands of Ford F150 owners with the lovely 5.4L 3V engines that are ready to join your "Never buying brand X again" club.

I did look at your history and see lots of small problems which I agree is annoying, but with the sheer amount of Hemi's out there we are sure to have some with quality control issues.

Tossing away a 2012 vehicle for another, especially if you are not fixing it, is a big financial loss, I would rather tough it out and have it properly fixed, but to each their own.

 

I apologize i started this thread last night after thinking of how much i have put into this vehicle in the amount of time i have had it. As you have stated i did deal with the AWD system failing, i have also replaced blown upper control arm bushings, and i have replaced coils and got Chrysler certified spark plugs. When the durango started knocking at start up i first started the journey of figuring out the problem and took it to an exhaust shop to diagnose if there was a broken manifold bolts because i have read from many threads it is common and creates a knocking sound. The shop did there inspection and found no broken bolts and did a pressure test which was good. I have read many codes and they are always misfires on different cylinders and at points i will let it idle and get a mulitiple cylinder misfire. The only thing i have delt with before on a common issue for engine knock is low oil flow but my engine oil pressure is good unless the egineering for this engine is poor and there is bad circulation. I have learbed from my research that when lifters fail they start a round of misfires and could cause the noise. It is a common problem so thats why i have jumped to that conclusion. It has not been diagnosed at this point but it is frustrating!

I agree that it would be nice to fix the problem but if the fix is to change the cam and lifters. It is an ordeal of diving deep into the engine with a price of $1500 or let the dealership do it at $4k +. My plan as of this moment is to trade it in and hopefully i get close what i owe. I have also seen remanufactured engines with better engineering at 4k, but i am not positive i want to spend the money to fix a car that has not been stable since i have had it. At this moment it is still drivable and i have not seen a decrease in efficiency but it is quite disheartening to just start the engine.
