5.7L Hemi MDS lifter failure on a vehicle that has less than 96K miles. this is regarding the MDS system lifter and the cam shaft lobe slowly getting wore away until something fails. still available for inspection, i have not attempted to rebuild that cylinderhead bank yet. camshaft/lifter/valve failure at highway speeds could make the vehicle stall and potentially lose control if engine fully seizes or creates drag to the drive terrain. Dealership claims that the "tick" which is horrifically loud inside the passenger cabin on startup and less loud once the oil warms up. is "normal" for these trucks. I am planning on having a 3rd party mechanic give a second opinion before paying to have the engine rebuilt no warning lamps yet, I stopped using the vehicle after it was determined that the tick was indicative of engine failure on most Stellaris 5.7L hemis (challenger, ram 1500, etc.)

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.

The exhaust manifolds have cracked. This can lead to dangerous fumes getting into cab and extra pollutants to the atmosphere. It can also cause premature engine failure which could be deadly if it happens while driving. This is a known defect with this engine. Thank you

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.
