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
As I was operating my vehicle on I95 northbound smoke began to pour out of my vents. I was able to pull over and was able to determine there was a fire behind the radio in my truck. I immediately grabbed the personal affects that I could grab and called 911. However within 5 minutes the cab of the truck.was engulfed im flames.
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.

Right Rear seat Heater got so hot it burnt a hole in the seat. This happened without any warnings. Seat cushion material was burnt badly enough that an interior fire may have resulted. There were no warnings/messages. Nor symptoms of problems prior to the incident.
On the date of 11/11/2022 the vehicle experienced an electrical fire in the engine compartment. This happened after the vehicle completed a heater grid cycle before starting remotely. All signs of the fire from photographs clearly show the fire starting from the ground bolt location of the heater grid. This seems to be a common issue when researching forums among other owners of the same vehicle with the same engine options. There were no warning lights or other indications of a problem with the vehicle before this happened. Thankfully I keep a fire extinguisher in my vehicle and was able to save the vehicle. It is currently at a dealership awaiting parts and further confirmation of the fire source.
The radio/Uconnect system won’t turn on. It’ll take days before it will turn on every time it stops working. It’s been doing this on and off since I bought the truck. Backup alert won’t work The blind spot alert doesn’t work
Multiple electrical issues since new. These include passenger seatbelt light and sound flickering, battery failed after leaving me stranded. Most recent was the heated steering wheel quit working. When I took it to the dealer to repair they said I had a bad clock spring but it is back ordered. Without any repair my heated steering wheel now works but my horn doesn’t function and cruise control doesn’t work properly. There is clearly a vague underlying electrical issue causing failures.
The tires have premature wearing and cracking . Tires need to be replaced The DEF tank was replaced in 2021 and once again needs to be replaced. The plug for heating er on the oil pan is defective and sparks. The radio shuts off and won’t come back on. The blind spot sensors don’t always work. Truck sometimes won’t go into park or let you shift it off
2nd visit to dodge dealership, While towing a trailer with the trailer electrical plug in use, the trailer breaks keep going out, I am driving down the road and the dash warning comes on saying the trailer breaks are disconnected. When trying to stop, at first I will not have trailer breaks, so I have to bare down on the truck brakes to stop the trailer, then the trailer brakes start working and jerks the truck back. Also, when not towing a trailer the dash warning comes on saying incompatible trailer?? No trailer is plugged in. At the dealership all day, they are telling me nothing is wrong. It is NOT the 5th wheel trailer, I spent $1,200 on new brakes, electrical and plug for trailer. It is the truck.
I was driving my truck on 10/26 approximately 9 am when the engine made a loud knocking noise and then proceed to make a erratic clanking noise. The truck proceeded to completely shut off while driving, rendering me unable to control the vehicle as all systems shut down. There were no warning lights present or any other warning signs. It coasted to a stop on the side of the road. The safety of myself and anyone around me was at high risk as I had no ability to control the vehicle. The vehicle only has 12,000 miles on it so I had it towed to the closest dealership, Autostar of Hendersonville NC. It took a week to get a diagnosis because their solitary diesel tech was on vacation. They offered my no loaner vehicle and FCA has not made an adequate offer to cover the full cost of a loaner vehicle. The diagnosis on the vehicle was a high pressure fuel pump failure. I currently have not ETA on parts and no vehicle to drive. It is my understanding that NHTSA is already investigating this issue. Multiple attempts made to get help with a loaner vehicle, an ETA on parts/install have all been met with deflection from dealership and FCA customer care representatives. Any attempt made to inquire if the new fuel pump/system has been adequately updated to ensure this wont happen again has not been answered. Any attempt made to inquire if this issue has cause long lasting damage to the engine has not been answered. This is a serious problem and needs to be remedied. FCA needs to step up and take care of its customers.
The trailer electrical plug located on the sidewall in the bed of the truck was not connected at the factory. I could have experienced a complete trailer braking system failing when towing my 5th wheel. Yes, vehicle was inspected by Harper Dodge in Alcoa TN, The trailer electrical plug was connected to the electrical system.
RADIO AND DASHBOARD WILL NOT TURN ON WHEN I START THE TRUCK. THEY ARE COMPLETELY BLACK AWFUL SCREECHING NOISE RANDOMLY FROM UNDER THE HOOD
THIS VEHICLE WAS BOUGHT LESS THAN A MONTH AGO. THE FIRST WEEK 3 TIRES SENSORS ARE OUT AND NOT WORKING, THEN YESTERDAY, OCT. 20, 2020 THE ENGINE LIGHT CAME ON AND WON'T GO OUT. WE CALLED THE DEALER AND WERE TOLD THAT IT WASN'T ANY PROBLEM TO KEEP DRIVING THE TRUCK. THEY TOLD US THE SOONEST THEY COULD SEE IT WAS THIS FRIDAY, OCT. 23, 2020 AND THEY DO NOT HAVE ANY LOANERS. SO HERE I AM STUCK AT HOME AFRAID TO DRIVE THE RAM TRUCK COSTING MORE THAN $70,000 BECAUSE I MIGHT RUIN THE ENGINE. THIS IS UNCALLED FOR IN A BRAND NEW VEHICLE!!*DT*JB*DT*TR
