My 2020 Ram 2500 Mega Cab truck Dash Leather Covering is coming loose from it base and may interfere with the passenger Air Bag deployment that is under the loose material. My truck has only 36,000 miles on it and has been garaged kept since I purchased it new. *I found this information online. Ram 2500 trucks (2019–2023) frequently experience dashboard leather bubbling or delamination, particularly over the passenger airbag area. This bulging can compromise airbag deployment and is caused by adhesive failure, often requiring a full dashboard replacement. I contacted my local Ram service center. They advised my to contact Ram corporate regarding this Safety Issue. Key Details Regarding the Issue: •Cause: The glue holding the leather/vinyl to the dash substrate fails, leading to bubbling and peeling, which can create a ridge over the passenger airbag deployment zone. •Safety Risk: A warped or bulging dashboard can interfere with the proper deployment of the passenger-side airbag.

Hood liner repeatedly drops down out of its mounting points on the edge near the engine firewall. This is a manufacturing engineering deficiency that relies on shaped material to hold the liner in place. The dealer has replaced it three times, and the same thing continues to happen. Chrysler refuses to address the issue. My concern is what happens if the liner completely drops down on the engine while in operation.

Def pump failed twice with this vehicle and with that it does not allow the vehicle to run any faster than 5 mph after the countdown ends. Unknown how the exhaust being plugged and service was done to clean the exhaust ended up having the fuel pump and turbo charger needing replaced. Not sure if they went hand in hand and one causing the other. So far the vehicle only has almost 78,000 miles on it. Change oil and fuel filters at the vehicles scheduled computer system reports on the vehicle. I was having issues from service center having trouble resetting the exhaust system, which they said the system was not sealing properly. Took them a couple of days to get part from dealership to get it to seal and reprocessed the test which they said passed exhaust reset. That would explain the poor fuel rating of only getting 9 miles per gallon. If there was a complete fuel pump failure, not sure if that would compare to this being a safety issue. Not sure how engine would react, due to it completely failing or if the turbo would cause the vehicle to be unsafe. The vehicle is currently at dealership and only 1 out of the 3 are even available to fix this problem. Def pump is available, but unknown when the others will arrive. Service shop said it could be 3 weeks or 8 months for parts to come in. Due to being a back ordered item. Spent $70k for this vehicle, just to have it spend over 2 months in the shop. I do my own oil and fuel filter changes, due to it being faster and cheaper than any dealer or shop.

2500 Truck randomly activates emergency braking for no reason. Occurs a couple times a month. Every occurrence has zero obstructions in front. I took it to the Tate Ram dealer (frederick MD) and they refused to update their software unless I pay them +$285.00. The Ram dealer is even aware of the software issue. I told them this is a life safety issue and not my fault. I requested the fix immediately but refused. I also have an active full MOPAR warranty, and they still said it's not covered. This is insane

Subject: Fuel System Failure Resulting in Engine Damage – 2020 RAM 2500 Pickup VIN: [XXX] Complaint Summary: I am submitting this complaint to formally report a dangerous and costly fuel system defect in my 2020 Dodge Ram 2500 Pickup (VIN: [XXX] ) that has resulted in catastrophic engine damage. Although Chrysler has issued a recall for the high-pressure fuel pump (HPFP) in many 2020 Ram trucks equipped with the 6.7L Cummins engine, I was told that my vehicle was not included in the recall—even though it exhibits all the classic symptoms of HPFP failure. This is a safety hazard and a potential emissions violation. Details of the Incident: In June 2025, I brought my truck to Tracy Chrysler Dodge Jeep RAM after experiencing engine misfires, loss of power, and a knocking noise. The dealership diagnosed a P0303 cylinder misfire and noted a fuel smell in the engine oil, as documented in repair order #[XXX]. Despite extensive diagnostic work—including compression tests, leak-down, and injector swaps—the misfire remained unresolved, and a tapping noise persisted. The technician explicitly noted fuel contamination in the oil and suspected internal engine damage due to a fuel system issue. To further investigate, I submitted an oil sample to Blackstone Laboratories. The lab confirmed the engine oil was heavily diluted with diesel fuel—over 10% fuel contamination, which reduced the viscosity from 5W40 to the equivalent of 5W20. This is consistent with HPFP failure leaking fuel into the crankcase. The oil report also noted excessive steel wear and recommended immediate oil change and fuel system inspection. At no time was a check engine light present, nor was there a clear diagnostic code for HPFP failure. Chrysler continues to deny responsibility even though the evidence clearly points to a failed HPFP—a well-documented issue for this engine model and year. The cost of diagnosis and parts alone has exceeded $4,000, and the engine is likely destroy INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The parking brake will not operate. Upon inspection the teeth on the gear are broken causing it to lock at top position. Dealership would not warranty safety part at 30,059 miles on vehicle so now I am left with no parking brake to protect vehicle from rolling on hill. Keep in mind vehicle is always used for towing 12,000 pounds or more.

Ram and it's parent company know there is an issue with the brake systems on their 3/4 ton pickup trucks. The 2500's. There is excessive travel in the brake petal and not enough pressure builds up in the system to activate the brakes correctly and adequately. It's all over the ram 2500 online forums. Many people are experiencing this issue with new trucks. Ram and its parent company Stellantis are unwilling to do anything about it.

Too much travel in brake pedal. Feels spongy. Weak brakes, hard to stop vehicle. Have to put pedal to the floor. Was told this was OK and normal at the dealership. Has been like this since I bought the vehicle new.

Vehicle randomly shuts off during normal operation. Same as if the Start / Stop button were activated. Vehicle coasts until it self applies the emergency brake at about 3mph causing a sudden, jerky complete stop. Switches itself to Park. Dash indicates “sterp on brake to restart”. Vehicle restarts normally but may randomly shut down again. Safety risk is loss of steering, loss of power brake control, and total loss of power in traffic. Taking it to dealer today. Vehicle has not been inspected by anyone yet. No messages or warning lights display. This is a recent problem but recurring with increasing frequency.

Traction control kicks on while driving on dry pavement and the truck bogs down like there isn’t any power. The truck slows down abruptly and will not speed back up without pulling to the side of the road and I have to shut it off and reset. The drive selector knob lights starts flashing and now they don’t come on at all. This has happened on 4 occasions

Issue is that the on the Diesel intake heater core has a bolt that comes loose from inside the manifold and can fall down into the cylinder and can cause catastrophic failure.
