Page 3 of 7: complaints 41 to 70 of 166, newest first, as owners wrote them.
Cracked exhaust manifold. I know of three people, besides myself, with the 2020 Ram with 5.7 literally Hemi that have had cracked exhaust manifold. Mopar has a technical service bulletin, but the cost to repair is on me.
My truck would engage the emergency braking without any objects near. Battery needed to be replaced due to not charging. The etorque is making noise and vibrating.
Sitting in traffic, truck started overheating. Gauge was jumping all over. Truck had to be turned off
The contact owns a 2020 Ram 1500. The contact stated while driving 65-70 MPH and towing a trailer, the traction control engaged, and the vehicle went into LIMP Mode. The Police had aided with getting the vehicle off the roadway. The traction control and engine warning lights were illuminated. The vehicle was taken to the local dealer, and two unknown local dealers were unable to determine the failure. The vehicle was not diagnosed or repaired. The brake control was previously replaced. The manufacturer was contacted and referred the contact to the dealer and the federal safety agency Hotline for assistance. The failure mileage was approximately 2,500.
Exhaust manifold is ticking after only hitting 47k miles. Of course the warranty has been out for a month now. The dealership won’t cover it quoting me $3,200 to replace both of them.
Due to the recall Z96/the federal safety agency 22V‑767 my fuel pump failed in 2023, causing my check engine light to come on due to a fuel injector warning. The dealership replaced the fuel pump, but nothing else was replaced or checked. In April 2025, my check engine light came back on for a #4 Glow Plug issue. The truck at this point had 56k miles on it, and was out of warranty. I took it to a local mechanic, who found the glow plug had shrapnel on it, causing it to fail. He believes it is due to the high pressure fuel pump failure the previous year, releasing debris into the fuel system. This is a safety issue due to the loss of engine power, and if multiple cylinders are affected could cause the vehicle to go limp.
So I am driving on the freeway 70mph and I get a message on my dash that says service shifter then every single light on the dash came on and started to make a beeping noise. I pulled over on the side of the freeway and then all the lights dissappear except check engine. I continued to drive to next exit and this time all lights came on again and truck appeared to be shutting off and turning back on while driving, steering wheel got hard to move all while all lights turning on, on dash. I have taken to shop 3 times first time they told me it was battery so I purchased battery and diagnostic fee for 600. Still continued to have issues even after replacing battery. Then they tell me they don't know what's causing this issue and the truck hasn't been fixed. I'll let the truck sit a few days and check engine light is gone and it will drive normal until the issues pops up again. I just don't know what to do about issue and have lost hope nobody seems to know what's causing thr issue. I have videos of this happening multiple times and I show to shops and they are just im awe and can't figure out what is happening. This happened to me yesterday 4/25/25 and while driving the truck started to show all lights on dash and immediately put itself into park while I was driving about 20 mph. Turned the truck off and started it back on again and got the service shifter message and drove home slowly and truck sat in driveway. I've taken in the truck multiple times and nobody seems to know what is causing the issue and I'm tired of spending money things they believe it to be. Any help would be greatly appreciated as we are starting to lose hope on this vehicle and are thinking about letting get repossessed as it's not useful to us if it can't be fixed
The contact owns a 2020 Ram 1500. The contact stated while stopped at a traffic light, there was an abnormal rattling sound coming from the engine. The contact pulled over to the right side and attempted to restart the vehicle; however, the vehicle failed to respond. The contact stated that the vehicle was taken to Town and Country Garage. A dealer was contacted. The vehicle was towed to a dealer where it was diagnosed that the engine had failed and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure but offered no assistance. The approximate failure mileage was 61,000.
Driving down the road, my auto start stop failure light appeared on dash, followed by a check engine light and a battery light. Tried to pull over on the side of the road when I lost all electrical components including power steering, ac, radio etc. the truck slammed itself into park abruptly and turned itself off. I was stranded on the side of the road and nearly got hit by passing cars several times as I was in a curve in the road. After further investigation it has been determined that the bearings inside of the generator (part number: 68623194AB) went out. The part needed to fix the truck is not being made by the supplier and I have been nearly 2 months and counting paying for a truck to sit and look pretty as the truck is completely unusable. One dealership told me this part was on back order for over Five thousand customers.
The contact owns a 2020 Ram 1500. The contact stated that while driving 25 MPH, the vehicle shut off; however, the vehicle kept running for several more feet. The contact attempted to bring the vehicle to a stop. There were no warning lights illuminated. The vehicle was towed to the residence. While the vehicle was at the residence and turned off, the alarm sounded. The vehicle was then towed to a dealer, but it was not yet diagnosed. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 77,000. The VIN was not available.
The 48V Belt Starter Generator failed on my 2020 Ram 1500 with the 5.7L eTorque system. It caused my truck to stall in the middle of a busy intersection at a red light. The battery drained fast, and I couldn’t move the truck out of the way. I was stuck in a dangerous spot cars were coming around a turn at 45–55 mph, and since my hazard lights started dying too, I had to get out in the rain and wave people away so they wouldn’t hit me. I was honestly afraid for my life. I ended up calling 911 and my insurance to get towed out of there. Before it happened, I saw a battery warning and something about the battery system. A mechanic and a dealer confirmed the issue was the 48V generator. I started calling around for the part, and every dealer I spoke with told me it’s on national backorder. One told me there were over 2,600 people already waiting for it, another said over 3,000 are on the list and no one has any idea when they’ll get them. There are a lot of people dealing with this, and it’s not just an inconvenience it’s dangerous. This part failing leaves people stranded in traffic, sometimes without power or lights. Something needs to be done. A recall would be the right thing.
The Alternator Generator (MGU) failed and I was driving on the road when it happened causing the electronics to start going dark one after the other then dark screen and lost power steering. Thank God I was close to the side of the road and rolled out of traffic's way. The truck was towed to the mechanic who confirmed it is the MGU. The problem is that this part is on back order with no ETA. So I have a 2020 RAM Laramie with 39,000 miles only sitting in the shop. If this happened on the highway, an accident would have been guaranteed. I was simply lucky.
1. Safety Issue 1: Cracked Exhaust Manifold & Exhaust Leak Description: Loud knocking noise on startup, strong exhaust fumes entering cabin. Dealer Diagnosis: Both exhaust manifolds cracked, multiple broken bolts. Risk: Potential carbon monoxide poisoning, engine damage, and fire hazard. Dealer Response: Refused repair, quoted $3,500. No assistance from Chrysler. Pattern Failure: Online forums show many owners with identical issues—clearly a manufacturing defect. 2. Safety Issue 2: Dashboard Delamination & Toxic Fumes Description: Dashboard surface peeling, strong chemical odor in cabin. Risk: Toxic off-gassing causes headaches/nausea; peeling material obstructs visibility. Pattern Failure: Widespread reports for this model/year—faulty adhesive is to blame. Manufacturer Negligence: Chrysler and dealerships are aware but refuse responsibility, blaming "wear and tear." Exhaust leaks and toxic interiors are unacceptable safety hazards—yet no recall exists. Request to the federal safety agency: Investigate these defects for potential recall. Force Chrysler to acknowledge and repair affected vehicles. Urgency: Driving this vehicle is a health risk. the federal safety agency must act before more are harmed.
The contact owns a 2020 Ram 1500. The contact stated that when the vehicle was started, on several occasions the contact observed an abnormal ticking sound coming from the front of the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.
Around 86,000 miles, a metallic like noise that one would associate with a worn bearing began within what i determine to be the E-torque MGU. Subtle at first, but you could tell something wasn't the same with the sounds you hear within the engine. Between then and my current 88,800 miles, the metallic sounds has gotten more aggressive, which is logical to assume that might happen if a bearing part is wearing down. Just today, 3/21/2025, an uncomfortable rattle sound and visible vibration of the MGU unit appeared suddenly, making me uncomfortable to drive the vehicle any further without immediate repair for fear of risking un-necessary damage to other critical engine componenets.
Smoke, burning smell entering cabin area while driving and using heater. Look up issue, found many people had the same problem involving heater core leaking/failing early.

My 2020 Ram 1500 5.7L e-Torque started making a noise. I then received a "Battery" indicator Light, then received an "Engine" indicator light. I was losing voltage on my battery. The truck is now at the Dealership. The alternator has failed (87k miles). No one has the part. It's been on back order since November 2024. Online research indicates that over 3000 are on back order. I can't even place an order with Mopar (Genuine Ram Parts Supplier). I'm also told that the repair will be $2300 - seems like a lot for an alternator that you can't get that can be replace in about an hour.
I was driving and started hearing a noise, come to find out it is the mgu. I have heard this is a raising problem for a lot of people with this vehicle.

MGU bearing failing, and no stock available, they suspect it may be months before the part is available
I already sent one, and forgot the pictures, pictures included this time
The DPF got so hot in a matter of a few miles (8 minutes driving) it blew a hole in it, and melted all the wiring under the truck, caused the engine to stop, automatically locking all the doors (thank God my child and husband had stopped and were out) before this happened.
Vehicle had a temporary shutoff when doing a rolling stop. The vehicle temporarily lost power when decelerating to the stop sign at 5-10 MPH, then starting again as I began to accelerate. Can not replicate problem again.

I noticed an oil leak under the truck a few weeks after getting the oil changed at the dealership. I took it back and had them investigate. They advised me I needed to replace the oil filter housing assembly, to the tune of $1,000. As I did research i found d this this is a widespread common problem and is known. Faulty design of a plastic part. For this to be such a common issue and poor design (that could cause catastrophic engone failure resulting in accidents or fires) and not to be recalled and or covered is insane. It's such a known issue that aftermarket parts makers have made a version that is all aluminum to prevent the issue. RAM should be paying for the repair, not me.
complete engine failure driving on hiway in 65mpr traffic.. it was a sudden total stop no power no control. after 30 sec. or so i pushed restart button stepped on gas, no error code was shown but restarted. we were almost rearended as busy traffic going that speed. this has happened twice before. after taken to a chrysler dealership on DEC.30 ,2024 and a diagnostic run they could find no issue so we were given no answer. they could not offer any other advice. this situation could be a lethal issue. we could have been in a horrible accident. we would appreciate anything you could do for us. we are affraid to drive this and only 50thousand miles on this truck,which we bought new. We are not mechanics and only can think this is a electrical failure.Please help us. we think another vehickle should be given us. This is a 2020 ECO diesel 30L engine 1500 Dodge Ram 4X4
Push start button failed during highway driving and cause the engine shut down /lost power After dealer checked: they said: - the push button stuck - air damp cannot close - CV Axis loose (safety concern) The truck is less than 5 years and only 69K miles. The quality of the truck is not realiable.
Power Distribution Center/Relay box failure. Contacts in box melted for ASD Relay. Incident occurred while driving on the highway at 65mph. Vehicle without warning had power loss in accelerator, and started downshifting gears. Dash immediately said “park and restart required.” Attempting to start engine, vehicle would crank/no start. After several attempts, vehicle restarted and resumed normal driving until “park and restart required” happened again. After vehicle shut down multiple times on highway, I was able to make it home and diagnose problem. I checked the fuses and relays on the PDC and found ASD relay intact with no burn or scorch marks on contacts. However, the socket is missing contacts within the pdc. I reproduced said problem by moving the ASD relay with vehicle running. There are no warning lamps, messages, or codes to show any kind of failure.
