2020 RAM 2500- frederick, MD
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

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.

2020 RAM 2500- Fairfield, TX
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.

2020 RAM 2500- Fairfield, TX
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.

2020 RAM 2500- Green Bay, WI
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.

2020 RAM 2500- Rockport, WV
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
