Water pump failure, vehicle equipped with a concentric water pump with no weephole. Same concern as T51 water pump recall affecting 2013-2017 Ram trucks with 6.7 diesel engine. This vehicle built 12/2012 but is considered a 2012 not a 2013. Current recall applies to 2013 models built after Oct 24th 2012.

At approximately 11:30 pm, I heard a vehicle horn honking outside in the driveway. Got out of bed to investigate. Observed my 2102 Ram 3500 diesel truck with lights on and flashing and horn was honking. Keys for truck were in the house. Went outside with keys and tried key-less entry fob to open the cab door with no success. Smelled smoke. Opened drivers side door with regular key to see lights on dashboard all lit up. Opened the hood to see lots of smoke and observed glowing wiring harness next to driver's side battery. Harness was glowing orange all the way from the firewall to the fuse box (power distribution module) next to battery. Went into garage to get wrenches and fire extinguisher. Disconnected driver side battery but the electrical harness was still glowing orange and smoking. Next, disconnected auxiliary battery on passenger side and wiring harness stopped glowing and burning. Truck was parked in driveway, in front of garage, next to the house. Keys were not in the vehicle at the time. Vehicle was parked and not running at the time. Vehicle had not been started or driven for approximately 2 weeks prior to the spontaneous thermal event. Vehicle had approximately 56,500 miles at time of thermal event. Massive short circuit appears to have originated in the fuse box (power distribution module) under the hood, causing all wires leading out of the module to short circuit, causing massive and total electrical system failure.

Something in transmission (68rfe) failed and dumps fluid out of the transmission dip stick tube onto the turbo which could cause a fire. This happened while driving and smoke started coming out of engine compartment. I was driving on a city street in the town I lived.

Truck shuts off at random at various speeds and after coasting will start itself up again. Throws every light on the dash on including trailer brake malfunction but throws no ECM codes. I'm pretty sure it has to do with the key fob/starter relay recognizing the key.

While driving down the highway, the vehicle stalled. I lost power steering, brakes, all electrical, and engine power. Everything stopped working and went black. Luckily I was not pulling a trailer, have to stop, or turn fast. If I would have, I would have crashed. Consumer stated fuel pump failed and it had a bad ground. Above the rear axle. It had electrical issues. Backup camera blacked out, reverse lights come on and stay on, lights and blinkers flicker.

The 2012 Dodge Ram 3500 4X4 6.7 diesel will intermittently stop running. The gauges will all go dead, the engine will stop running and will not start up again until the vehicle is completely stopped, put in park and key turned off and then back on again. It does not matter if the vehicle is at high or low speeds, with or without a load, pulling a trailer or running empty. Once it has started back up, it may run for a couple of weeks or a couple of hours before it does it again. It does not seem to be affected by temperature or weather because it has happened in hot and cool weather and wet and dry conditions. Yesterday it happened when I was merging onto the freeway at 70 mph. Last week it happened when I was pulling out of my driveway at less than 5 mph. Road surface does not seem to create the condition for the problem to happen either because I have been on both smooth surfaces when it happened and on dirt roads happened, always at various speeds. Has anyone else experienced this problem or is this truck just an oddity?
