We do have an extended warranty on the vehicle thank goodness. All maintenance is up to date on this vehicle. The vehicle is at the dealership now and parts will not be in until October 24. It is not driveable at this time.

Component Failure: Around 45,000 miles, my vehicle equipped with the 5.7L HEMI E-torque V8 had both exhaust manifolds cracked with large exhaust leaks pre-catalytic convertor Safety Risk: My vehicle equipped with the 5.7L HEMI E-torque V8 was idling in a parking lot for around 1 hour while I waited inside the vehicle. Cold ambient temperature with windows up and heater on. I noted having a slight headache and started smelling what seemed to be pre-catalytic convertor exhaust fumes (rich fuel smell). I stepped out of the vehicle and smelled the exhaust at the rear of the vehicle, which did not match. I attributed the smell to a nearby vehicle. One week later, the same event occurred with no other vehicles parked around me. The exhaust leak was large enough to pull exhaust fumes into the cabin through the HVAC system. High risk of carbon monoxide poisoning if the vehicle was to sit long enough, risking both myself and my child's safety while we sat in the vehicle. Problem Reproduced: Yes, brought the vehicle CJDR dealer who diagnosed the vehicle with "both exhaust manifolds cracked" and replaced both exhaust manifolds under warranty. Has component been inspected: Unknown. Parts were removed from vehicle as covered under warranty at dealer and replaced with new parts. Any Warnings: No warning lights on dashboard or DTCs for catalytic convertor performance, lean/rich banks, or other exhaust/emissions related. Exhaust seemed slightly louder on cold start. Smelling of unburnt/pre-cat exhaust fumes that prompted dealer visit.

Broken exhaust manifold bolt. Allows exhaust gas to enter engine compartment.

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.

Exhaust manifolds leaking at cylinder heads due to broken manifold bolts.

Truck engine has shut off when coming to a stop or slowing down making a turn. Yes vehicle is available for inspection. Vehicle has stopped in the middle of roadway Problem has happened multiple times, has not been confirmed Vehicle has not been inspected No warning lamps or messages.

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!

The contact owns a 2020 Ram 1500. The contact stated that while operating the vehicle, the odor of exhaust fumes was present inside the cabin of the vehicle. Additionally, there was a loud exhaust sound while depressing the accelerator pedal. The local dealer was contacted. The local dealer stated that the failure was due to a crack in the passenger’s side exhaust manifold however, the parts needed to repair the vehicle were on backorder due to a high demand. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 43,000

Exhaust manifold bolts snapping at low milage causing exhaust to possibly leak into the cabin. Most people are getting manifolds resurfaced and replacing the bolt's. If you replace manifold with new, it will warp again and break bolts again. Apparently the manifolds were not “Stress Relieved” in the manufacturing process. Lots of people are complaining and Ram dealers are saying it happens a lot. Cost to fix is approx. $1,000.

The exhaust flange bolts are prematurely rusting and breaking on the Exhaust system. This is a truck that has less than 30,000 miles and less than 4 years old. This is a common problem but seems to me RAM is using sub par materials in there bolts and they are failing at an earlier than expected time. These parts should be good for at least 80,000 100,000 Miles. These parts should be covered and a recall should be issued for these bolts as they are failing and braking prematurely. Creating a safety hazard as if the exhaust flange bolts break the pipe would hit the ground and create a safety and or accident hazard.

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.

I was making a right turn after being stopped at a light and made it approximately 100 feet before the vehicle just shut off. I was able to steer to the side of the street, stop, and restart the vehicle. I didn’t hear or see anything abnormal but it all happened so far. The dealer is looking at it now (in the next 5-7 days). This is a real safety concern.

2020 RAM 1500 HEMI Broken manifold bolts had fixed with 34,000 miles now the truck has 40,000 and DO NOT BOTHER CALLING MOPAR. they can care less. said i needed to take to dealer and then call back to see what they can do so I asked the rep how many ram owners have yall helped when they took the truck into a dealer for diagnostic out of warranty? 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. Where they want to charge a fortune. Something needs to be done about this.

5.7 V8 right rear exhaust manifold leaks exhaust gases due to broken manifold bolts. Weight of the exhaust header appears to fracture the header bolts causing the leak. Seems to be a common issue for the vehicle.
