With only 68,000 miles on the vehicle the engine has experienced a cam failure causing a fire and explosion hazard. Gas backfires through the carb, engine shakes really bad at idle, and engine misses while applying power to the engine going down the road at all speeds. Ten thousands of hemi engine failures reported on online forums. Also had to replace both exhaust manifolds around 50k miles. The bolts cracked and gave way. Ten of thousands of this issue reported online forums as well. Truck was bought as a demo with 2k on the vehicle at Edie Chrysler Bismarck ND.

I was driving down the road on Monday, June 27, 2023 at about 50 mph. All of a sudden the engine just seemed to go into limp mode and slowed down rapidly. The power was gone and the car seemed to not go over 35mph. The after driving another 1/2 mile I arrived at work. When I tried to turn off the engine and restart it was difficult. There was a long crank and then started. I got the car to the dealership and they say it threw a ode of P0336 which is for a Crankshaft Position Sensor and I needed a new Reluctator/tone wheel and crankshaft position sensor for $2,300. In researching the problem on your site I saw there was a recall but my VIN isn't included. Why? I also reviewed many Ram forums and I saw many similar complaints by Ram owners having the same problem and not being included int eh recall. It sounds like Fiat Chrysler gave the NHTSA some bogus info to limit the recall coverage. Its time the NHTSA force them to expand the recall to all EcoDiesels!. They clearly have not corrected the issue in their product! Its very unsafe at highway speeds and someone is going to get hurt.

I purchased this truck brand new and am the original owner. This truck has been in the dealers procession probably over 50 times and in the shop probably close to 200 days. Most all repairs have been about computer, smog, or other engine problems. Chrysler has extended my warranty out into 2025 and extended the miles to 125k. I currently have 82k miles. It just was in the dealer 1 month ago and currently has check engine light on again. They state it is for a recall they have no current fix for and it sounds like their not even working on one. I was told that this years model with the 3.0 diesel will be the last. I went to then ask for a trade in value from a Ram Chrysler dealer, and was told they could only give me low auction value. I have an additional over $7k in improvements that I will loose. Any help or suggestions would be appreciated. Thank you

I believe that Ram and It-??s parent company have intentionally not provided a recall fix for recall z46. If Ram refuses to provide a fix for the problem, and I-??m forced to drive the vehicle that could stall and crash at any time is absolutely a safety hazard. I-??ve contacted Ram cares and was told that if I-??m not comfortable driving the vehicle, to just park it and wait for a fix. This company not only provides faulty and unsafe vehicles but then forces its owner to drive them with no fix provided.

catastrophic engine failure due to the failed high pressure fuel pump, last year march 2022 my truck started stalling then lost all power to the engine the truck would not start. i took the truck to my mechanic where he Found no crank signal while engine cranking and sounded to be out of time. he Tested fuel flow from lift pump and found it to be correct. Tested injector weep line return flow and found no return this is normal, Tested fuel flow regulator at high pressure pump and also found no return while cranking this is normal. These test indicated that the high pressure pump has fail. Installed new high pressure pump and still no pressure. Removed pump and noticed it had not rotated from its timed installed location. This indicated that the drive gear is not rotating the pump and there is internal damage to engine. this damage happened due to the filed fuel pump.

I-??ve experienced 3 separate incidents with this truck that resulted in the engine shutting down while in transit as follows: 12/6/2019: engine stalled when accelerating up a hill. Used momentum to pull mostly out of traffic lane. Towed to dealer where crankshaft positioning sensor was replaced under an extended warranty associated with the Ram Ecodiesel emissions related class action settlement. 5/21/2021: engine stalled while towing a boat up hill on the interstate. Had to cross right lane traffic to the shoulder causing traffic behind and to the side to swerve and honk. Just made it to the shoulder. Diesel fuel was leaking. Towed to local diesel shop where high pressure fuel line was replaced at my expense. This would have been replaced under the aforementioned warranty had it been towed to a Ram service center. 5/28/2023: engine stalled while towing a boat on the interstate. Coasted to the right lane and down an exit where I made it to the shoulder. Had it towed to the nearest dealer who reported the engine as seized and in need of replacement. Ram customer service will not discuss any financial assistance in replacing the engine or in the cost of an engine tear down to determine the cause of the failure even though it-??s possibly related to the outstanding fuel pump recall or the previously mentioned emissions recall. In all instances, especially those on the interstates, I felt that I was at risk of being involved in or causing an accident as I had no control over maintaining forward momentum. I opened a case with FCA Customer Care (case# 86310172 ) but they will not share the case information with me for reasons of policy, so I-??ve no documentation to upload other than the engine replacement repair doc from the dealer. The information below reflects the latest incident.

Rapid loss of coolant over rear of engine and transmission bell housing. Danger of overheating and fire. The cause of the rapid coolant loss is a common well known problem - turbo coolant pipe! Of course the small tube requires cab off the repair - design flaw!! Additionally, being a known issues and the part that fails is rubber, FCA has not issued a recall or TSB for the replacement of the rubber part with a much more durable siliconized part. My rapid coolant loss occurred on a busy highway and the vehicle required towing - not safe!!!! BIG design flaw and safety issue!!!!!

Both manifolds were leaking exhaust into the cab causing an unsafe environment for the occupants inside the truck. With only 68,700 miles on the truck it was discovered the passenger side exhaust manifold had several broken bolts. It was also discover driver side had cracked exhaust gasket. Now the engine ticks with just 68,700 miles on it. The mechanic is telling me I need a new engine. Truck was purchased new and had regular scheduled maintenance. I think these costly and sufficient repairs should be covered by the manufacturer. Too many failures in this engine to be coincidental.

This engine and many others have catastrophic internal bearing failures. FCA has failed to accept and has voided many engine replacements. Please advise or look into.

My engine light came on. I had the dealer hook it up to their diagnostic machine. It came back that cylinder 4 was misfiring. They looked into it a little farther and my camshaft and Lifter was no good. I bought this vehicle used and there had been no recalls fixed on it. We did have the airbag recall fixed. The Hemi 5.7 engines seem to have this problem and is well-known for it.

My RAM has been diagnosis with the same faulty manifold bolts as what seems to be numerous other 3rd and 4th generation RAMs and is resulting in dangerous exhaust leakage along with the potential for it to cause heads to cease while driving. I discovered the prevalence of reports of the same issue after my dealer diagnosed the issue while repairing a faulty air bag that has been recalled. The dealer quoted me $2,031.89 to make the repairs (see attached). In one forum alone, there are 100s of people that have cited the same issue and some have left their NHTSA complaint IDs: 11321983, 11317189, 11321434.

Catastrophic engine failure, resulting in a hole in the block!! My truck is like new, with less than 53000 miles, perfectly maintained. You could eat dinner off the engine it is so clean. This is the second time a 5.7L hemi engine has failed me. I leased a 2012 Ram and the engine had to be replaced on that( under warranty)! HELP. This is a MAJOR $12,000 repair which should not be taking place! Truck in shop now, but to Labor Day weekend, I have no paperwork at this time. Please let me know what you need. Thank you

I have flawlessly taken care of my Ram truck. My check engine light came on P0303, cylinder 3 misfire. I had to replace the camshaft and lifters on both sides of the engine due to a continuing design flaw in the Hemi engine. This is a well known issue and it should be addressed by the government.
