At a stop light after 10 min of normal driving on country and city roads my truck started smoking from front passenger wheel well. Smoke intensified and quickly turned black. Immediately pulled over and found flames burning through front passenger wheel liner and from around passenger side battery and intake filter. Fire was put out with fire extinguisher and engine bay sprayed down by fire truck when they arrived on scene. Fire melted through battery case leaking battery acid, parts of the intake filter housing, all surrounding electrical wiring and completely through wheel well. Was building in intensity until put out with fire extinguisher. Truck was purchased in June 2021 and had 0 active recalls. Truck was completely stock.
My 2021 Ram 2500 6.7 truck quit on me driving down the road. When I raised the hood I could smell burned wires and see smoke. Luckily, it was raining or I think my truck would have burned up. I noticed melted plastic and burned wires on the drivers side of the truck. This particular truck had an Electrical system recall and shows to have been completed. (Safety Recall 13A/NHTSA 23V-060) If this recall was completed, maybe something else needs to be checked out. The truck is currently at a dealership to be repaired, but I will still be scared of it catching on fire because the dealership cannot tell me why or how the fire started. 03
Fire on sliding portion of read window. Short on connection point of wiring harness for defroster. Dealer verified and confirmed. All has been documented. Also has had PCM and other electrical components real places two times now, along with other electrical issues that are still ongoing since time of purchase back in March of 2021. John L. Sullivan of Yuba City refuses to do work or rectify this issue. Ryan Triebess, the service manager, has a personal attachment to online reviews and refuses work to any paying customer that voices their dissatisfaction leaving me with a truck that to this day is a fire risk.

I have attempted to get 2 recalls that require parts completed at my local Ram dealer who has called me both times saying that the parts were in, and they were ready to schedule the appointment to complete the recalls. The first appointment was on September 25th, 2023, and when the vehicle was checked in, I was informed they had no parts to complete 2 of the 3 recalls that existed at that time. They completed the recall that required no parts and said I was put back on the list for the ones that required parts with no answer of why the parts were not available (I had been put on the list for the parts in June). I received another call in the middle of November that the parts were in and scheduled an appointment for the 18th of December. …
My local Ram Dealership in Del Rio, Texas (Ram Country), has refused to repair my open recalls on my 2021 Ram 2500 Diesel. This includes the heater relay recall and the transmission dipstick recall. I have visited the dealership on at least 5 occassions and each time I am put on a new "waiting list". Ram Country has informed me that they get parts weekly and will call me to schedule needed repairs, however they never do. What can I do to get my recalls fixed, and finally closed. I get FCA recall notifications warning me to get my recalls completed, however again, my local Ram Dealer refuses to schedule a repair, and continues putting my on a waiting list, and has recommended that maybe I should get a new vehicle. …
This recall has been open, and my local dealership has the part available. However RAM will not allow them to "complete" the recall, stating that parts are not available from the manufacturer. If the parts are available for sale today from the parts department, that statement cannot be true,. Furthermore, according to the NHTSA website, the "Phase 3" remedy, was to begin on 5/11/2023, and has not begun yet. This is unacceptable to have my children and family at risk of injury or death from vehicle fire because the manufacturer is slow to remedy this known problem.
