Filed Oct 22, 2025 · Brakes, Driver assistance · 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

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

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.
