My 2012 Dodge developed an engine issue at 129,000 miles. The issue was rough idling and no acceleration. I took it to a Dodge dealer. They diagnosed it as a chronic cam issue with this generation Chrysler hemi engine. I had the cam and replaced at Waldorf Dodge. The cost was at $3400. I believe this is a known problem and Dodge is aware of exactly why it happens. Lack of oil pressure to two of the cylinders that are dropped while driving for fuel economy. This should be Dodge problem not the consumer. I take excellent care of my vehicles. I also have a 2004 Dodge truck but that's over 450,000 miles on it same engine same transmission.

The vehicle finally became inoperable at 119,000 miles due to lifter failure. Lifter issues started when the vehicle had about 106,000 miles on it. There were multiple misfire and gas mileage became worse. There was a loud ticking noise coming from the engine as well. Vehicle has been well maintained and only 1 owner, purchased new. With the lifter failure, this caused damage to the camshaft and which led to an excess amount of metal shavings to be spread throughout the engine. The vehicle ultimately had to get a engine replacement because of the excess metal shavings in the engine.

Warning light came on suddenly. Vehicle lost power. Smoking out of the tail pipe. Very dangerous for other drivers. Took the vehicle to a mechanic, said I have problems with the lifters, and need to replace the engine. I don't know why Chrysler doesn't issue a recall for this issue, it seems to happen often. Thank you very much.

I am experiencing a loud exhaust manifold leak for the third time now in this vehicle. The previous mechanic told me the bolts were broken and this is a known problem with these Rams. I can't afford to keep fixing this issue. This isn't an inexpensive fix. Please help

The exhaust manifold bolts have broken off inside the block 3 times in 7 years. I have fixed them every time. Most recently, I was advised by service manager at Lithia Chrysler Dodge that 4 manifold bolts were broken and the repair cost $1490. This is a very common issue that needs a recall.

Complete engine failure caused by lifters sticking due to lack of lubrication which is a well known problem with the hemi engines. It occurred in my case at approximately 140,000 kilometres despite being maintained religiously with all oil changes done at 5000 kilometre intervals using synthetic oil. Only fix possible because of the damage was to purchase a new long block at a cost of approximately $8000.

My 2012 Dodge Ram shuts off or stalls for no apparent reason. Sometimes upon starting, while going down the freeway (at freeway speeds), as well as speeds in between, This has happened with my family in the vehicle and even when we are towing our stock trailer with animals inside. This is very scary for all of us and dangerous for all those on the round around us. While we have not been involved in any accidents, its just a matter of time. There is never any warning when this happens and it not only shuts off it looses power to everything. So times it catches its self and restarts, other times we have to manually restart the engine.

Issue is that the exhaust manifold studs/bolts break off in cylinder head(s) on 5.7L Hemi engines causing exhaust leak in engine compartment in which could allow carbon monoxide to be drawn into passenger compartment. I personally replaced all the bolts/ studs along with new gaskets each time. Even once replacing exhaust manifolds only to have this issue continue to happen repeatedly.
