2020 RAM 1500 Problems

I bought this used truck with 60K miles on it in 2024. It is a 2020 truck. At 136K the engine failed.........with the infamous [XXX]. I have an excel summary spread sheet on all maintenance I had done since I owned this truck and I did not pull or haul anything. I heard a tick for about 10 days before I took it to my dealer whom I bought it from and they stated after "scoping" that the # 8 cylinder misfired and cylinder wall scored and the lifter pin bearing failed thus cam shaft damaged and exhaust manifold cracked. They had to replace the engine with a remanufactured engine from [XXX] and replaced intake and exhaust Manifold at a cost of $ 15,021 out of my pocket. I was stuck with no options logically. I do not have a problem with the Dealership - [XXX]. I have a problem with Ram Engineering, Stalantis design. To me there is no excuse to have a big cast iron block v-8 fail at 136K miles. There are many more ram owners who have this same problem I just stated that I had. If I knew then what I know now i would have never bought this truck with this 5.7L engine. There were no warnings, messages or anything displayed to alert there was a problem. I expect that there was not enough oil flow to # 8 cylinder ( which is all the way back to the left rear ( passenger side) of the engine ) looking from the front of the truck as I read many Ram forums on line. I changed to oil every 5K miles with Mobil 1 full synthetic oil along with the filter - either Mobil 1 or WIX filters. some of the best on the market. I do not know what I can do now but this is rediculous. I won't get burned again. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Twice in the past two years, the eTorque system had failed will driving on the highest. When the unit fails, you lose all power asks if you're battery is low, you can pose the ability to even steer. The first time, I was on the i87 going north, and barely made it off the road. I was nearly hit by several semi trucks because this was on a blind turn with very little shoulder and I basically had to hide in the woods for safety. Just this past week, less than two years after the replacement, the same issue happened again. This incident was on route 11, which is very busy and I was unable to get my vehicle of the road. An officer came to shield me until the tow truck came, but it was very sketchy. This total cost is over 3000$, and no support from Ram as to why this is happening. This past time the bearings went and there was a lot of smoke coming from the engine area. The smell of burning electronics was choking in the cab; at that point I had to get out of the truck due to the toxic fumes. I did file a complaint with them. With this being such a safety concern, why is there no recall? I can't be the only person having had to deal with this. From what the dealership says, this is happening a lot and there is currently an 8 month wait for the part. Just thought you should be aware of this very serious issue.

"Factory rear window/brake light leak allowed water to flood the interior cabin, destroying the RF Hub module. This caused the vehicle to dynamically stall at 40 mph in traffic, creating a severe safety hazard."

Odometer Fraud. The contact purchased a 2020 Ram 1500. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 95,205, and at the time of reviewing the documents, it was discovered that the mileage was 95,911.

Recall 01A was performed on my vehicle, but the replacement fuel pump failed again, contaminating the entire fuel loop with metal shavings and risking sudden engine stalling in traffic

Fuel pump failure and fortunately it failed when I had stopped to get fuel.

The contact owns a 2020 Ram 1500. The contact stated that there was water leaking from the rear window of the vehicle. The contact referenced Technical Service Bulletin: 23-098-23, detailing a crack in the rear window near the third brake light that could allow water to enter the vehicle on the left and right sides. The contact confirmed that the vehicle had experienced leaks on both sides. The vehicle was taken to a dealer to be repaired under the TSB; however, the dealer declined to repair the vehicle. The contact stated that the vehicle met the mileage requirements, but the dealer stated that the vehicle was not included in the TSB. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 115,000.

A crack developed in the plastic frame of the rear sliding backlite window, allowing water to enter the vehicle cabin from the rear glass area. Water intrusion has been observed on the rear seating surfaces and interior trim during rain and snow events. The condition has been reproduced multiple times during precipitation and car washes. A dealership inspected the vehicle and performed a sealant repair following manufacturer guidance; however, the water leak persists and the crack remains visible. Water entering the passenger compartment presents potential safety risks, including moisture exposure near electrical components, mold growth, and occupant health concerns. Water has entered the rear seating area where child passengers ride. No warning lights or electronic alerts appeared prior to the condition. The issue appears related to a structural failure of the rear backlite frame seal. The condition remains unresolved and may worsen over time if not properly repaired. The component is available for inspection upon request.

As I was driving the cooling fans started roaring. About 30 seconds later the Service power steering light flashed and I lost all power steering. As I was trying to pull over the steering came back intermittently. This almost made me wreck because I would be tugging on the wheel to turn and then all of a sudden have almost no resistance and violently turn.

While traveling at 40mph, total los of steering. Vehicle veered off the road and was uncontrollable. Power steering service light illuminated seconds before steering was inoperable. Turned off vehicle and restarted. Issue was not present after restart. Vehicle was recovered, sent to dealership for diagnostic. Problem could not be replicated at dealership. The next day, vehicle had the same issue. This time in a school zone. Vehicle is now parked and not driven out of fear.

MGU Failed, 48v code P0DAF had early signs of premature failure. when on the highway, vehicle shut off completely, no power what so ever. Couldn't steer correctly and vehicle was going highway speeds (approximately 70mph) dealer has confirmed the issue being there MGU gone bad, but I have records of water intrusion multiple times on the rear seats, headliner & back glass (XL1) and water intrusion can cause BPCM to go bad along with the MGU to go bad. they first appeared on or around December 2025, most likely way before that but just never noticed it. check engine light came on and showed a code for the BPCM going bad and then I had the CHMSL replaced 3 times under warranty & then the 4th visit they did they urethane warranty superseded the XL1 and even after that fix, there water leak still occurred and dealership wouldn't fix it they stated Stellantis denied the back glass replacement and further repairs because im out of warranty but the warranty expires 8 Years/150,000 miles and my vehicle is only 6 years old and sitting at 118,350 miles. but the entire problem with water intrusion most likely started anywhere from 60-70,000 miles ago. even when I purchased the vehicle at 39,801 miles I noticed the water stains on the headliner but was advised the CHMSL caused that so it was fixed so technically the CHMSL was replaced roughly 4 times along with the original making it a total of 5 CHSML. so my issue is that its highly possible that the water intrusion that was never fixed for thousands of miles and many months leaked into the rear seats near the 48V Battery pack and eventually started shorting and lead to the MGU going bad. so this all could've been avoided if dealership fixed the water leak many many visits ago. along with the MGU could've been replaced under the major emissions comp warranty way. before that ever expired when it showed signs of premature wear like DTC codes popping up at 100,000 miles and even many more visits prior to December.

I PCSd from Springfield, MO to Fort Bliss Texas. I bought the truck [XXX]. I make it to TX. Driving the first Saturday in TX on [XXX] it just shuts down and put me in a very scary situation. I was stuck in the middle of the high way. It does not drive. The Etorque/generator is bad and is now on order from my local Dodge dealership. It literally shut down my truck and will not start, run, nothing. It’s been in the shop for 40 days with a no ETA on the part ordered. This should definitely be a safety recall as it just stalled me on the highway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The electronic gear selector on my 2020 Ram 1500 intermittently displays a "Shift to Park" warning while the vehicle is in motion, specifically during downshifting or braking. Each occurrence is accompanied by a physical jerk or lurch, consistent with the vehicle momentarily engaging an unintended gear. The warning clears without driver input. These events occur during active deceleration and represent a loss of predictable vehicle behavior, creating a serious risk of rear-end collision or loss of control. The problem has not been resolved. A dealership inspected the vehicle and recommended a Transmission Control Module (TCM) software update referencing TSB 21-019-24, to be performed at the owner's expense. No root-cause diagnosis was provided. The underlying hardware cause, most likely the gear selector position sensor or transmission range sensor, was not confirmed or ruled out. The dealer is insisting the owner pay for the software update without establishing whether the bulletin covers the reported symptom or whether the vehicle VIN falls within its scope. No warning lamps preceded the first occurrence. The symptom appeared without prior indication and has recurred across multiple drive cycles.

ABS light keeps coming on and off. The 4WD keeps going on and off and the cruise control and traction keeps working then not working. There is a recall for other year models for the ABS system that basically is exactly what’s happening with my truck. I am worried that it will go out and my truck will stop and cause and accident which almost happened today. This should be a recall alongside those other year models.

The contact owns a 2020 Ram Promaster 1500. The contact received notification of NHTSA Campaign Number: 25V552000 (Back Over Prevention); however, the part to do the recall repair was not yet available. Three dealers, including Cross Jeep Chrysler (1501 Gardiner Ln, Louisville, KY 40218), were contacted. The dealers informed the contact that parts were not yet available and there was no date for the availability for the parts for the recall repair. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not notified of the issue. The contact had not experienced a failure.

Possible main body module, started with a false "bad tail light" notification.. then a "blind spot alert unavailable service required" then screen, ac, and most electrical controls/ actions gone ie (driver side door windows, running board, etc.)

Tailgate gets stuck and will not open.

Tailgate not operational as one of the 5 latch assemblies doesn't know if rear doors are open or closed. If truck has a bed cover it would be impossible to get rear doors open as access would be impossible without destroying the bed cover. I've owned a 2021 & 2020 with this problem covering many production years besides mine. Driving down the road the OPEN SWING GATE indicator starts flashing & buzzing constantly RAM needs to step up & accept responsibility for this design flaw.

The contact owns a 2020 Ram 1500. The contact stated that while driving at an undisclosed speed, the air bag warning light unexpectedly illuminated. The vehicle was taken to the dealer, where it was diagnosed and it was determined that the air bag had failed and needed to be repaired. The vehicle was repaired; however, the failure recurred. The manufacturer was not made aware of the failure. The approximate failure mileage was 61,590

One day five different warning lights appeared. Since, air bags, seat belt tensioners,traction control,abs,and 4x4 have been disabled

The tail lights keep going out on both sides. The tail light harness does not fit the female adapter properly. You have to hold it pushed in to get the light to come on but when you let go it turns back off. I have already replaced the sockets with Mopar OEM parts and am still having the problem. After researching I found that this is a common issue with this vehicle. It is a safety concern because without tail lights keep other drivers may not be able to see my vehicle at night or when I am braking.

I am submitting a report regarding the hacking of my vehicle that has persisted over the past five years. I have previously stated that my scammer, [XXX] , along with her associates, continues to remotely manipulate the gear of my vehicle while I am driving. Furthermore, they are targeting the lighting and dome lights in my vehicle in an attempt to jeopardize my safety. Additionally, the manufacturer experienced a data breach in September 2025.

Air suspension freezes making is useless. This is dangerous and causes back injuries. Parking vehicle in warm garage thaws it but it refreezes quickly outside in use.

The rear driver-side wheel detached from the axle, resulting in an immediate loss of vehicle control. As a result, the truck left the roadway. The detached wheel landedapproximately 150 feet behind the vehicle, on the opposite side of the road from where the truck ultimately stopped. Insurance has not yet completed its inspection of the vehicle; however, the crack and damage to the wheel were observed at the scene by a volunteer firefighter, the responding officer, and the tow truck operator. Additionally, an independent witness reported that the truck appeared to abruptly lift off the roadway, as though something suddenly caused it to “go flying.” Due to the sudden nature of the incident, no warning lights illuminated prior to the loss of control. All airbags deployed during the incident. The tailgate was dislodged, and the driver’s side of the truck sustained severe damage, including significant damage to the axle. The vehicle is not operable. While insurance has indicated the truck will likely be deemed a total loss, the claim has not yet been finalized. Video documentation is available showing the location of the detached wheel relative to the truck’s final resting position.

The drivers back seat seatbelt failed. My daughter and I were driving, and I had to stop suddenly, her car seat had been secured with the seatbelt and the seatbelt unlatched and sent her car seat flying through the cab of the truck.

While driving my 2020 Ram Rebel, the driver side seat belt locked up and will no longer retract. I took the vehicle into the Larry H. Miller Chrysler dodge dealership and they attempted to fix it but they were not successful. My truck only has 58,809 miles on it and they stated that it was no longer under warranty and that I would have to pay to replace it (roughly $750). Prior to the seatbelt locking, there were no indications that something was wrong. I believe not having a seatbelt that works properly puts myself or anyone else that would drive my vehicle at great risk if there was an accident.

Both Driver and Passenger Visor arms have dis-engaged and no longer work to provide shielding from blinding sun. They just hang from thier broken arms and it happened shortly after having purchased this vehicle from a used car dealer, (Kearny Mesa) and they were unable to address since it was not a recall. Obviously they would repair it for $$$$ Did some research and apparently this is a common issue with this vehicle.

The contact owns a 2020 Ram 1500. The contact stated that the dashboard lamination had started peeling and was delaminating. Additionally, there was bubbling on the driver's side and the passenger's side of the dashboard. The dealer was notified of the failure, but the vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 40,000.

While traveling down C470 Eastbound my truck experienced some type of mechanical failure. While on the corner above the bridge for Wadsworth Avenue I felt a sudden loss of control with the truck pulling to the right side of the highway. I immediately took action to pull the truck off the highway while also wrestling for control of the steering to keep the truck from running into the barrier and off the bridge. I was able to bring the truck to a stop just following the bridge (About 100ft). Upon inspection I found the right front tire had folded under itself. It seemed that the upper control arm on the vehicle snapped, pulling out the drive shaft in the process and damaging items like the steering linkage, brakes, tire, brakeline, etc. Dealership diagnosis was: Found right front upper ball joint separated causing excessive damage to the front end components. Only additional work that has been done to the truck was by MOPAR with their 2 inch lift kit, certified by Fiat Chrysler and Mopar for this specific truck. Kit number 77072424 SUSP KIT-LIFT. Dealership did inspection of vehicle 2 days prior to incident with no issues found. I was not able to attach pictures and PDFs to this form
