Filed Aug 6, 2026 · Electrical, Lights · MO · fire

While the vehicle was sitting in the driveway not running, the back of the headlight caught on fire. There wasn't any incedents (e.i. any collision, repairs) prior to the indecent. It is available for inspection. No dealership report yet, but have an appointment with local dealership Tuesday to get an itemized estimate for the repairs.

My headlights (specifically on the driver side) keeps going out randomly. I have replaced the high and low beam bults 3 times and the wiring harness twice. I can be driving down the road and they it will go out and 10 minutes later it will just come back on all on it's on. I looked on all of the Dodge discussion forums and this seems to be a very common issue with this make/model of the Dodge Ram 1500 I recieve no error messages on my dash console telling me that this has occurred. However, every other bulb that has ever went out gave an error on the dash.

Intermittent fault from the TIPM module. When slowing to a stop, or slowing to make a turn, the engine dies without warning resulting in loss of power steering and operability while in traffic. The only indication that the engine has died is the tachometer reads 0 RPM, loss of power steering, and the excelerator becomes inoperable. The radio, headlights, and A/C stay on during this. Coming to a complete stop and putting the truck into park (P) and turning the ignition to OFF and then restarting the truck resolves the problem, but on the highway this is EXTREMELY DANGEROUS. This has been diagnosed as an intermittent fault derived from a faulty TIPM module and involves multiple RAM 1500, 2500, 3500 owners. Various issues of similar nature reported to dealerships and on forums.

I went out to start my truck and there was only one headlight working. After replacing the left driver's side bulb multiple times and it still didn't work I had a mechanic look at it and he figured out it was a wiring connector problem.

Win moduel(wireless ignition node module) vehicle has 90,000 miles. When key is inserted into ignition and turned to the start position the win module fails to make a circuit internally and will not crank the vehicle. The faulty connections inside will also move while vehicle is in motion causing the vehicle to shut off at sometimes a high rate of speed. Resulting in loss of brakes,steering, lights, etc. Serious injury or death may occur because of this issue. My personal vehicle has done this repeatedly while in motion and also when starting. The latest occurrence being last night when driving 60mph down a rule stae hi-way we lost complete power!!! No head lights, no engine, no power breaks, no power steering, everything was dead. This was very scary!!! Was able to come to a stop in the middle of the hi-way and turn off the key and everything powered back up. This could have ended a lot worse!!! This is a known problem with other chrysler models and should be recalled on this one also.

Passenger side high and low beam headlights will go out at any time. Was told the problem is the tcim. Major safety issue if they go out when driving down the road in the dark. It is my understanding that the tcim is very expensive and may only solve the problem temporarily.

Drivers side headlights, both high beam and low beam , will not work. I have replaced 3 times in 6 months, reset the tipm once, and will have to again. This is a chronic issue with ram tipm. (google it, pages of results) I am driving without a headlight half the time now, keeping bulbs in my truck, but it is not easy access to change bulbs on the fly along the highway.
