2020 RAM 1500 Unknown Or Other Problems

Faulty check valve and EVAP canister/vent While fueling the vehicle, the automatic shut-off closes and will not allow it to fill the tank. This causes fuel to spill out due to backing up in the fill hose. It takes approximately 15-20 minutes to fill the vehicle because the fuel backs up, the pump clicks off prematurely, and it will not allow the fuel to flow consistently to complete fueling. When the gas spills out, it splashes on the person filling the tank, on the outside of the vehicle, and on the ground. This is a dangerous safety issue. The vehicles has not been inspected by a dealer or mechanic yet. There were no warning messages or symptoms. The vehicle has 65,000 miles. The vehicle is available for inspection. I understand that this is a common issue for this vehicle and should be recalled.

While driving the power plant generator for my engine failed without warning, causing my truck to stop working. There has to be a major issue with the part due to the fact that there is 6000 part back order that has been in going for over 2 years. Someone is going to get seriously injured if this part isn’t recalled and corrected. Having your car shut off at highway speeds is unacceptable. Part number 68623194AC. Ram knows there is a serious issue with this etorque power generator and is not doing anything to resolve the issues, nor making parts available to correct the issue.

RF hub has now failed 3 times in the last 10 months. The last time they replaced the third brake like and now I am having the same issue. Dealership is telling me it’s the back window and that they will not pay for the problem to be fixed. Safety at risk by vehicle breaking down with no transportation on the side of the road. Problem has been confirmed by dealership which led to first repair. No warning prior to failure.

A warning “Service Electronic Stability Control” is on and off when I’m driving. Brought it to local Ram Dealer but they said they can do anything about it.

While I was driving my vehicle, the power steering warning came on and moments later the steering wheel locked - I could not steer my vehicle. I stopped the vehicle and it started firing all sorts of warnings. It was like all systems went haywire. Service shifter, service power steering, service electronic stability control, acc/fcw unavailable, service required, service airbag system, collision control, check engine, anti-lock breaks. The windshield wipers started without being tuned on, the engine revved up an got very loud like an airplane engine. I turned off the vehicle. When the tow truck arrived, the truck would not start so he walked away to grab the pulley and the truck started on it's own. My biggest concern is that I lost the ability to steer while I was in motion. I was informed of a VB8 recall for power steering but told my vehicle didn't qualify. This...

I opened my passenger side front door. The running board deployed. When the running board contacted my shin it automatically retracted. However, my dog got his paw caught between the running board and the truck frame. The running board did not sense the obstruction. I had to hold my dog down to close the door and open it again to deploy the running board. My dog bit me in the process because he was scared.

Bolts in the 2nd flange on the exhaust before the muffler break due to manufacture issue. Causes an exhaust leak and an issue with the vehicle power.

I took my 2020 Ram 1500 EcoDiese to a Chrysler-Dodge-Ram dealership on 9/23/25 for the High Pressure Fuel Pump (HPFP) safety recall. I was told a part had to be ordered to complete the recall and gave me a rental vehicle. After a few days I contacted the dealership about my repair. They said the wrong part was ordered and the new one was in route. After about a week, I called the dealership again and I was told "the truck won't start and they were working with Stellantis to figure out why." Several more days passed, I called again, they stated that after the new pump was installed and the truck was started it "blew a rod," but they had fixed it, test drove it, and it would be ready for pick up the next day. I picked up the truck on 10/16/25 and drove less than 50 miles...

Exhaust manifold bolt broken causing exhaust gasses to leak in engine bay. Due to location of exhaust leak, it pulls exhaust gases into cab.

Turn signal does not shut off regardless of the position of the turn signal switch. Appears to be an issue with the SSCM. The malfunction makes safe turning/lane-changing impossible. It has been confirmed by the dealership but has not been inspected. There was no forewarning prior to the malfunction and no indication besides the malfunction itself.

On June 26, 2025 there was heavy thunderstorms throughout our area. I was driving to my office to pick up an item and all of a sudden my dashboard lit up with numerous error messages. I turned the truck off and could not get it to start again. I had to have it towed to the dealership and they cleaned some electrical connectors and returned it to me. My wife picked it up and on the drive home the windshield wipers went off and she also had numerous error messages on the dashboard so we returned it to the dealership. They replaced some modules as they found rust and returned the truck to me. When I went to the dealership to pick it up the truck would not start. They then said there was some corrosion in the star connectors and some moisture behind the radio. They replaced parts and...

On multiple occasions while making a slow turn. My vehicle would shut off put itself in park and set the emergency brake. My truck does have the etorque and I see this is a known issue with etorques. I it happened a few times and I thought it was just a fluke but after my last incident I did some research and found out it is an issue.

The dashboard leather on my 2020 Ram Longhorn (VIN [XXX] ) has severely bubbled and separated from the underlying structure. The warping creates dangerous glare and distortion in the windshield, compromising forward visibility. Additionally, the deformation extends over the passenger side airbag panel, raising serious concerns about whether the airbag can deploy correctly. This is a well-documented defect on 2019–2020 Ram Longhorn dashboards due to adhesive failure, not wear and tear. FCA/Stellantis is aware of the issue and has issued technical bulletins, but many vehicles remain unrepaired. This should be treated as a safety issue and addressed via recall or extended coverage.

Software issue with 12' display unit. The issues began occurring over the past several months. Sirius XM radio frequently searching for signal lasting for hours, and nothing else would play, not the radio nor the Pandora app with UCONNECT. The backup camera displayed on the screen when in D. Then, on 6/10/2025, the backup camera stopped working altogether. When shifted into R, 12' display shows a blue screen with "Camera System Unavailable." The camera control buttons are fixed in position. On 6/11/2025, the 12' display showed Sirius XM subscription update and left me with the Sirius preview screen even though I have a subscription. This lasted several hours. Upon, restart, Sirius shows loading again. Still no backup camera.

Currently Ram has extended its warranty on the back break light due to a leaking/sealant issue on certain models and years. The truck also leaks through the window frame that crakes in these vehicle's. It seems that maybe this isn't being looked at as a safety concern and think it should be. Water leaking in due to this issue is now causing stagnant water. I have 2 kids that sit in the back of the truck and have been subject to breathing in the mold that has built up. I believe the result of mold growth is a great safety concern. I have seen this complaint all over the internet and even on the 5th generation website. I think a full investigation on this should be done immediately. It also seems Ram is aware of the issue because they no longer install this window. We have always had the issue...

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...

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...

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 NHTSA: Investigate these defects for potential recall. Force Chrysler to acknowledge and repair affected vehicles. Urgency: Driving this vehicle is a...

Leaking back glass, Soaked carpet, and a musty odor.

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.

The vehicle exhaust gasket fails at 50,000 miles on the 2020 Ram pickup causing carbon monoxide to enter the cab when idling. This is very common on this particular truck. Ram has yet to issue a recall.

My screen is delaminating on a 4 year old vehicle. This should not be happening and was told by my local Dodge dealership that it is not covered under a warranty, nor my extended warranty or a recall. This is poor manufacturing. My vehicle does not sit in direct sunlight.

I was parked with my daughter in the truck and we heard a loud boom sounded like a gun shot. Then I looked my back window was shattered and the frame of the back window was cracked. I have researched this and found others who have had the same issue. Ram will not take care of it. My Mopar maximum coverage will not cover it. This very scary my daughter was in the back seat and glass went everywhere. I am a single father battling cancer and I do not know what to do.

I have a 2020 Ram 1500 pickup, and the rear window leaks on both side of the glass and runs down to the carpet and it is starting to smell really moldy. I took it into the ram dealership on 11-4-24, and they said they have had several complaints on this and said I could pay to have it replaced or they could put silicone around the glass to see if it stops the leak. I wasn't happy with this but I told them to go ahead and reseal it and they did. About a week later it was leaking again. I called Ram Cares both times and they told me that they have lots of complaints about this same issue as I'm having as well. Matter as fact my son also has a 2020 ram 1500 that leaks and my next door neighbor has a 2021 ram 1500 that...

Started vehicle in parking lot. Monitor did not come on, Put vehicle in reverse and still nothing, no image being displayed on console. After backing up and then selecting forward motion the display came on, but not until about 3 minutes of forward motion.

The truck has an issue with 3rd gear. It wants to jolt forward and if it doesn’t catch speed it goes into “limp” mode. It’s a safety feature where it goes as fast as 2nd gear needing service to Electronic throttle body, stop/start system, and electronic stability control.

My backup camera screen freezes and glitches two or three seconds at a time while I’m backing up and I can’t see what’s going on.

When driving the visor becomes detached and obstructs view while driving. The passenger side also detaches which can also obstruct view.

It has been 2 years since this recall came out and still I get the run around at the dealer that a solution is not available. What I'm I supposed to do still not drive the vehicle or drive as little as possible. this is rediculous and I need this recall resolved emmidiately.

Vehicle randomly says "shift to park" after making soft turns like going in a uturn under a bypass . Once the speed drops under 5mph, the truck then puts vehicle in park, and turns off. Dealership could not find the problem. Mechanics are unsure. Ongoing for 3 years. Very unsafe.

Dashboard leather shrinking and bubbling up that may affect air bag performance

While driving from Abilene, tx to Houston, tx on [XXX] my vehicle displayed intermittently several warning message. The first message said idle-stop was unavailable and lasted for about 30 minutes. The second message was displayed in red and stated the electric steering was inoperative and lasted for about 10-30 seconds and it was definitely harder to turn the steering wheel.

The sun visor retention plastic broke. Now the sun visor falls down obstructing vision and view of oncoming traffic while driving. This happens frequently. Trying to place the sun visor back while driving is difficult. Trying to hold the visor out of your field of vision while safely controlling the vehicle to a stop is difficult. The falling down of the visor is a serious safety hazard to anyone near a vehicle with this malfunction.

I was driving back from Montana and my passenger side sun visor disconnected and was hanging from the wire causing a visibility issue when driving. Approximately 1 year ago the same thing happened to my driver side sun visor. This also caused problems with visibility while driving because it wouldn't remain in the locked position. It would hang by the wires. Both times I had the visor replaced at the Dodge dealership in Prescott Az. I was told my the service advisor that it has been a problem and they have had to replace quite a few. I asked if they have fixed the problem and he stated that it hasn't and its still the original parts. This is going to lead to a serious car accident or death if this problem isn't resolved by Dodge.

While driving on 3/29/24 I pulled the drivers side sun visor down to stop the glare from the sun. In doing so the post for the sun visor broke causing it to fall down into the line of view while traveling approximately 70 mile per hours. This caused an issue that could have caused a catastrophic accident causing injury to myself or others. A review of the internet shows that numerous people have had the same issues with the sun visors breaking. This issue need to have a recall issued to it to prevent someone from being seriously injured or even killed. A tooth pick had to be placed into the rod area to hold the visor up so that I would be able to move the vehicle safely. Thanks for you attention in this matter.

Water damage recently started in back ceiling of truck above rear window. Coming in from somewhere. Also notice a large crack in plastic all of a sudden. Online research is showing a lot of the same complaints of cracks and water damage. I do not see a recall though? I've only owned the truck for 8 months and this has happened within weeks.

Inside cab is getting moisture in it. Prior to noticing this we had battery drainage that causes truck not to turn on. They replaced radio they found it was drain battery. We continued to have battery drainage where it wouldn’t turn on after a full charge overnight. The truck would go to turn on but would only make clicking noises and wouldn’t shut down for 20 minutes even though wouldn’t start. Other times we’d turn off truck and it wouldn’t turn off. Now our truck is molding inside and front and rear windshield drip of moisture. The moisture drips onto dash and down the console. This could affect electrical components. There is less then 10,000 miles on it. We’ve had brakes jam up on us when we back up and there is nothing even close to us.

To Whom It May Concern, The issue I am reporting is that the drivers side of my cargo bin on my 2020 Ram Rebel is opening on its own. This has occurred many times while I was driving and most times, items inside the cargo bin have fallen out on the road. This issue is also taking place when the vehicle has been parked and locked, as I come out in the morning or return from an errand and the ride side drivers cargo bin is wide open. I have also had items stolen because of this. This shortcoming is now also killing my battery all the time, since after I jump the vehicle, I can hear the locking mechanism attempting to lock and unlock on its own. I feel this is a huge liability since the contents of the bin are sometimes landing in the roadway behind my truck....

The drivers side sun visor has broken and is possible for it to fall onto the steering column while I'm driving, and also hits my head when it swings back and forth. I've read that this is a very common problem with the 2020 RAM.

Rear window leaking, just like on all the 5th gen rams. Causing water to get into the cab, causing mold, mildew, rot and moisture on the windows. Please create a recall this is affecting almost every single 5th gen ram

My tailgate opened during a 20 mile drive, much of it on interstate, while I had golf club bags in travel cases in the pickup bed. One of the cases unknowingly fell out onto the road. Fortunately this road was near my home and low speed, 2 lane. Someone stopped and picked them up since they saw them in the road. I am uncertain if my son just didn't properly latch the tailgate or if it came open after being latched but my primary issue here is that there is no warning light in my truck to warn me if my tailgate is open. Had there been I would have pulled over to close and latch it.

The rear window frame cracked causing water to leak slowly in and damage the trucks radio frequency hub. This crack is a known issue in 2019-2021 Ram 1500. There is a bulletin out somewhere about it. And what I’ve read is on an extended warranty called Backlite , which should be called window seal. I have seen this get covered and fixed because it is a known defect that the user did not cause. They covered the hub, which is required to start the truck and keep it running. That would be bad if it failed while driving. This crack needs to be covered. It won’t let me upload a picture of the crack, but I have one and how much they want to charge me to fix it. I was going to attach those.

I have a 2020 Ram1500 Laramie and the vehicle has developed a water leak. The leak is coming from rear window, window seal, or related components. The result is that the headliner has water stains on the rear passenger and driver side. Continued water leaks have the potential to cause interior mold or electrical problems.

While trying to accelerate from a stop, the vehicle electrical system turned off the vehicle and turned back on. When turning back on, it flashed through a series of error messages. One time was while in stop and go traffic and I was able to coast onto the shoulder and restart the vehicle. A second incident was in the middle of a busy intersection. Having had this shut down before, I was able to quickly turn on my hazards and restart the truck to then clear the intersection safely. I have personally had Dodge look at the vehicle under my ownership (bought it used from a dealer). In speaking with the service advisor, he mentioned it had 13 error codes reported on the DTC from loss of communication with PCM. There were no warning signs prior to the two events I have experienced. I have scheduled to take it back...

The bolts holding the muffler to the exhaust pipe sheered off. After speaking with multiple dealers it is a known problem using a smaller bolt in the new body model Ram 1500 DT. The smaller bolt can’t handle the heating/cooling and eventually snaps. But this generally occurs just outside of warranty time. With the undersized bolts used by the manufacturer this causes the exhaust pipe to hang freely and risks the potential to cause injury or death with parts falling. There are many cases like this at dealers across the country and more to come. This body model is just coming up on 3-4 years so more trucks are starting to come in with this issue.

The rear window, window seal, or related components have failed and allow water to intrude into the cabin of my vehicle near the back. This water gets the headliner wet and drips down the interior of the rear window, down the rear of the passenger compartment. This water intrusion occurs with very, very light moisture on the vehicle, such as early mornings with morning dew, light rain, or watching the vehicle. The near-daily (due to dew) intrusion of water into the cabin of my vehicle raises safety concerns of mold & mildew in the passenger compartment. My rear window backlite frame is visibly cracked on the interior, matching the symptom pictured in TSB [XXX]. My vehicle has a manufacturer date within the dates noted in the TSB. My vehicle also includes a power sliding window as noted in the TSB. I've been to two dealerships and they both told me...

A known exhaust manifold problem has caused exhaust fumes to enter the cabin which cause headaches and could cause serious issues while driving

Service electronic braking system stop working. Light and message on dashboard.

My truck has had two leaks in the rear window area. I have owned it for 3 years it has 30000 miles on it. The vehicle is in otherwise perfect condition with no damage and no accidents. The first time it required the rear window to be replaced. This time it is uncertain where the leak is coming from. This could cause damage to the electronics as well as the rear airbags. It appears like these leaks are common and Ram is aware of them, but the have not recalled the defective components and provided a new design that does not leak.
