Exhaust Manifolds have cracked twice on the right and once on the left side in the first 45K miles of the vehicles life. Both times replaced under warranty, there appears to be a design defect here that should be resolved. Leaking exhaust manifold in California will violate CARB emission standards.

Both exhaust manifolds cracked creating an exhaust allowing exhaust gases/fumes into the vehicles cabin causing an obvious safety issue. No warnings lights of any sort, the components were inspected by the dealership and confirmed that they were cracked. This is a recurring problem as a quick search about ram exhaust manifolds will provide a never ending list of stories and the dealer themselves stated they are constantly replacing cracked exhaust manifolds everyday and the parts are hard to get due to the issue being so common.

The start/stop feature on the truck has been malfunctioning and the light has repeatedly came on. The truck has stalled on me while driving on two different occasions. I was in the middle of driving on a busy road and also a highway and the truck stalled on me which could of caused any vehicle to the side of me, or behind me to hit my vehicle causing an accident especially when I have both my kids in the car. The dealer allegedly fixed the problem but clearly it is NOT fixed. The problem has been diagnosed by the dealer at their establishment. They say nothing shows the truck stalling in the computer but I have proof. The truck shook, the start/stop light came on along with the check engine light and then stalled out on me both times. I opened a case with ram care and they dont seem to be of any help nor is the dealer. The dealer refused both times to check the -??e-torque-?? battery that controls the start/stop feature for any failures or malfunctions and gave the excuse that theirs nothing indicating its the battery yet that battery specifically controls that feature. Ram has also recalled 131k trucks and wranglers for stalling. Ive brought the truck to them 2 times this month alone and they refuse to check that battery which 2 other dealers said was the problem. I would of brought it to the other 2 dealers but ram care advised to bring it to the dealer where I purchased the truck from. This is seriously unreal and if something happens or my kids get hurt due to an accident this is gonna be a major lawsuit. I need your help.

Since the vehicle was purchased new in 2020, the check engine light has come on and the service throttle body message has been displayed 12 times. It only happens when I am towing a 5,500 pound travel trailer. When the anomalies happens, I loose engine power. Say I am traveling at 65 MPH. When the anomalies happens and the CEL and warning messages appear, my speed drops to 32 MPH. Most Interstate freeway systems have a 45 MPH lower limit. I am forced to quickly pull over to the emergency lane to avoid a crash situation. If I shut off the engine and restart it, my power comes back but the CEL is still on. The selling dealership has tried to fix this several times. The engine code that is always present is a P00AF (turbo boost control -??A-?? module performance, I think over boost) and at one time a P0299 (turbo under boost). The latter occurred after I heard a loud -??whoosh-??. The turbo air hose blew off. So far the Dealer has flash programmed the engine control module, replace the turbo hose and lastly replaced the turbo itself. Not all of the anomalies have been documented by the dealer, as I am always traveling around the country when it happens and have called dealers in the city nearest me at the time and have gotten every excuse as to why they cannot look as it now. I am almost always able to resume my travels by shutting off and restarting the engine. When I arrive back home and take it in to be looked at, I-??m told there is no codes and no history of a code. It can be several thousand miles after the anomalies when the dealer finally gets to look at it. FCA (Chrysler corp) is aware of the situation and has opened 4 cases for my concern. Case # 77583210 which they immediately closed, # 78338328, #79796818 and just on 06-9-2023 case # 86383024. The vehicle now has 21,726 miles on it and most of them are towing miles. The vehicle specifications state this vehicle can tow 12,000 lbs. I bought this vehicle for vacations and towing. THIS VEHICLE IS UNSAFE!

My vehicle is a 2020 Ram/1500 BIG HORN/LONESTAR (with 5.7L HEMI - V8) My VIN is - [XXX] The Engine system failed/malfunctioned while driving on the highway. (It is currently available for inspection upon request.) I will however be taking the vehicle in for an engine rebuild and reinstall on or around May 30th, 2023. My safety and the safety of others was put great risk when my engine sputtered and vehicle rapidly slowed down on the freeway, during rush hour traffic; nearly causing rear end collision. Check Engine warning lamp came on and started flashing at the time of the failure, this was first time it happened. My vehicle was diagnosed from a mechanic/technician at Milosch's Palace Chrysler Dodge Jeep Ram in Lake Orion, Michigan. The technician said that the engine failed due to issue with Cylinder #7 and will need to be replaced - at a cost of nearly $11,000. I did find a licensed repair facility that will do a complete engine removal, overhaul and rebuild including a 24 Month Warranty. According to the gentleman at the repair facility, this is a common issue, and they are on working rotation, repairing 12-15 HEMI Engines at any time due to this common failure. 5.7L HEMI Valve Train issues have been documented over and over; this is a known issue for many years. There have been several cases where HEMI engine owners have filed lawsuits against automobile manufacturer, alleging defects or performance issues with their engines. In some cases, these lawsuits have been successful in securing damages for the owners. I could provide you with some general examples.

No response- shocker there. I stated that mopar knows about this ongoing issue for years and will not do anything about it. Only to be told that I have to take the truck to a dealer.

Manifolds. This is an ongoing problem with ram owners. They blow at early mileage and progressively get worse until the fumes are in the cab. This can be extremely dangerous and could cause unconsciousness or even death if it-??s bad enough. If someone where to become unconscious behind the wheel, it could put many people at danger.

November of 2022 I took my truck to the lithium dealership in Reno NV for an exhaust leak they reported back to me that they replaced the manifold passenger side. two weeks later exhaust leak returned they informed me that it was a lifter tick and there was no exhaust leak this was at 51,000 miles. The problem got worse I took it back to them twice with both times I'm telling me it was a lifter tick, but I could smell exhaust in the cab of the vehicle. Now that the truck is out of warranty it's 61,000 miles the exhaust leak got so bad I took it to a different dealership where they have found both exhaust manifolds were leaking and now that it's out of warranty the extended warranty has taken over. but with that said now I am without a car because the extended warranty does not cover loaner cars. the manifolds are both on national back order. the sad part about this is the lithium dealership said they replaced the exhaust manifold and they did not according to the Carson dodge dealership the manifolds were never changed. Apparently this is a known problem with these vehicles and the parts are on national back order. I just find it very disgusting that a dealership would kick the can down the road just so they didn't have to replace the exhaust manifolds or give me a rental car while my truck was sitting there so now I have my truck in the dealership with no ETA on when I'll get it back I'm having to rent a car on my own and still make a truck payments. Don't know if this is a common practice with Ram/Chrysler but this is a despicable way to do business. The second problem is the power steering assist stops working while I'm driving that is also at the dealership waiting for parts that are on national back order.
