2019 Ram 1500 Electrical System Problems

First off the service shifter keeps coming on and off every time I take it to the dealership it’s off so they can’t read the code. Then the parking sensors keep coming on saying unavailable. Today when the service shifter came on, it went right back off and then when I went to turn onto the highway it felt like the truck stalled for a second then it started driving normal again and down the road. The service shifter light came back on, then went off. All recalls have been fixed on this vehicle and when I took it in and was charged $300 for a diagnostic, they couldn’t figure out what was wrong because the light wasn’t on anymore.

Has happened 5 times, I also replaced the battery with a new one. Cargo light switch cuts on by itself and drains battery.Issues with rear camera after battery was charged. Also CarPlay doesn’t work sometimes.

My ABS module went out in my 2019 Ram 1500 Rebel.. My service “Electronic stability control” , “Service Trailer Brake System”, as well as “Service 4WD” lights are all on.. i had Auto Zone hook the computer up to my truck and it had 2 codes. C2206-00: Vehicle Configuration Mismatch and U0403-00 Implausible Data Received From T-Case. ABS module failure. I did some online research and come to find out there was a recall on my model truck for the ABS system needed updated.. I check my VIN online and says there are no recalls on my truck.. I’m having the exact problems stated in the recall and have the exact model stated in the recall. I was never notified about the recall. My truck only has 68,000 miles on it. NHTSA Recall # 24V-653. I don’t understand why my VIN wasn’t included in the recall. Thank you for your time

The backup camera sometimes doesnt show the lines. also the camera sometimes glitches while backing up. And the infotainment system sometimes wont let the music out of the speakers even turning off and on the stereo/truck.

The alternator/generator (part #68623194AC) stopped working and rendered the car undriveable. This happened while we were driving. It is available for inspection. The problem has been confirmed. The car started making a terrible noise prior to all of the lights coming on and it becoming undrivable.

The truck has two issues that may be related. The third brake light leaks water. they tried to fix it, it happened again. The leaks have ruined my upholstery of the back seats. They have an extended warranty for this but it should be a recall. I believe the leak also is effecting my push button (electrical issues), the car won't start. It just clicks and you have to remove the battery or do weird things to make it start again. I think the leak may be connected because there is a computer on the bottom of the rear window floor that keeps getting wet. The push button to turn the car on is a major pain and it happens at random times or after lots of rain. It can leave you stranded for an half hour or days. It also affects the power roof. I can't open/close the power roof without doing crazy things. The push button start is reported by thousands online. Dodge charges 50k and cannot provide basic start button that don't leave you stranded.

My 2019 ram 1500 started showing an intermittent warning light on the dash that said check check trailer brake, although I was not towing anything. I continued on my 20 minute commute and parked the vehicle to which point I noticed smoke towards the back of the vehicle. I inspected to see a small fire that apparently had started at the trailer tow module that had shorted and ignited the insulation and surrounding plastics. I was able to extinguish the fire with minimal damage to the truck, mainly the plastic paneling and the wiring and associated components were damaged. I'm reporting this because a vehicle fire is a significant safety concern and I'm probably not the first to have had this happen. I have made no aftermarket adjustments to my towing system and I've only owned the vehicle approximately over a year. The vehicle has about 83,000 miles on it currently.

Vehicle lost all power and shut off on two occasions during operation. Luckily steering and breaks were not impacted. Dealership was unaware what could have caused the incident. However, a local shop identified the alternator/power generator as being faulty. Ram 1500 owners forums show this is a widespread issue. So widespread there is a 8000 part backorder to order an OEM replacement part. Local dealership stated the part has been on backorder for more than one year.

The contact owns a 2019 Ram 1500. The contact stated that while operating the vehicle, the air bag warning light remained illuminated, and the message "Service Air Bag" was displayed. The cause of the failure was not yet determined. The local dealer was notified of the failure and informed the contact that the vehicle was not included in NHTSA Campaign Number: 25V298000 (AIR BAGS, ELECTRICAL SYSTEM). The contact stated that the vehicle had experienced the failure listed in the recall. The manufacturer was not contacted. The failure mileage was 62,000.

I am writing to report a critical safety defect in my vehicle, a 2019 Ram 1500 Big Horn , involving a catastrophic failure of the heater core (heater coil). This failure creates an unreasonable risk to motor vehicle safety as defined under 49 U.S.C. § 301. Safety Risk 1: Acute Toxicity and Driver Impairment The failed component is releasing vaporized ethylene glycol directly into the passenger cabin through the HVAC vents. Per CDC and ATSDR documentation, these fumes are known to cause respiratory distress and neurological impairment, including dizziness and confusion. While operating the vehicle, these fumes caused [describe your symptoms, e.g., dizziness or coughing], creating an immediate risk of a crash. Safety Risk 2: Severe Visual Obstruction The vapor creates a persistent, oily film on the interior of the windshield that cannot be cleared by the defrost system. This "flash-fogging" has severely restricted my field of vision during operation, which mirrors safety risks identified in NHTSA Recall 24V-011. Safety Risk 3: Electrical and Fire Hazard Liquid coolant is currently leaking into the dashboard area, which houses critical wiring harnesses and electronic control modules. This exposure to conductive fluid poses a high risk of electrical short-circuits and potential vehicle fire, as documented in previous NHTSA investigations (e.g., Recall 26V012). Supporting Information: * VIN: [XXX] * Current Mileage: 93000 * Incident Date: January 17 2026 I request that the NHTSA open a Preliminary Evaluation into this model’s heater core assembly to determine if a safety-related recall is warranted. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

December 26, 2025, while driving, the vehicle shut down, and it went into park. After researching the cause of the issue, the RF module had water in it. Additional research indicates the third brake light leaks into the cabin causing water to enter the module causing corrosion and a short. Vehicle was towed to the dealer for repair. Dealer indicated the RF module did fail. They also stated it may be caused by a leaking rear window. The service writer stated they would cover the brake light issue but not the rear window if it caused the problem. Water into the cabin by either area is obviously an electrical problem but also a fire hazard. Any water into a wire harness or component has the potential to short and cause a fire. Before the shutdown, the right front and left rear tire pressure sensors were coming on and off at times. The remote start became non-functional at times.

Purchased vehicle used in 2024 and purchased a 3 year extended bumper to bumper warranty. The center screen was restarting every 3 minutes and was draining my battery down to being completely dead when it was not running. On 12/15/2025 I brought the truck to a Ram dealer with the problem and it was diagnosed by the dealer (Sansone Auto Mall) as needing to replace the entire radio/HVAC center stack, and it was the cause of the parasitic drain on the battery. The work was approved by my warranty and the parts were ordered. It has been 11 weeks and the parts have not arrived and Stellantis has been unable to provide a timeframe of when the parts will arrive at the dealer to do the repairs. The truck has no defroster or heat rendering it unsafe to be driven on roads. I have had an open case with Stellantis for several weeks and call them frequently to attempt to locate the parts for my vehicle in which they are unable to provide me a delivery date and a repair timeframe.

On 2019 Ram 1500 Laramie Longhorn digital part of the front dash instrument cluster goes intermittently black screen once it gets warmer outside.

Have had several issues with this truck and there seems to be a lot of similar issues: 1. Hemi tick - Had to have the exhaust manifolds replaced because they were cracked for no apparent reason... happened right after warranty was up 2. Alternator (etorque) started whining and had to get it replaced after 100k miles gently driven. Could have left me stranded. 3. Visor falling out (Very Dangerous) No t only in my truck, but when I had 2 rentals from dealership, same truck different years (2021 & 2023) they had the same issue. All of these seem to be a widespread issue!

I was driving and my power steering went out .I took it to the dealership to find i had a alternator generator issue.

Instrument cluster does not work. This has been happening for months now, making vehicle speed and none of the guages or warning lights visible.

The etorque alternator bearing failure locked it up causing the vehicle to die in traffic while attempting to make a left turn. This alternator had been replaced 13 months earlier due to a bearing failure. I have now been waiting 2.5 months for replacement and was told today by Ram dealer that orders are blocked until the end of feb. The last time it failed I found the only one in the state to make the repair but not as lucky this time. 5000 on backorder nationwide with no delivery date. Truck is now useless

Start stop/ Battery/ Engine lights all came on and warning messages said, stop start unavailable and some electrical power loss. Vehicle was taken to dealership for repairs. MGU was defective (Motor Generator Unit). Was informed parts were not available back ordered. 5000 units on order no available parts.

Diagnosed brakes at repair shop and advised ABS Module failing. Saw online recalls for certain vehicles yet our 2019 has the issue and nothing was noted for recall. I have 4 daughters and our safety and the safety of others is at risk with a faulty system, The lights on the dash appeared a few days ago and went away and now have come back and have stayed on.

The RFH module is defective for the year and has already been replaced by a new model. When the module goes bad it can leave you stranded because it runs the security section of the computer. The computer will not recognize the key fobs, and the car can shut off and not restart leaving you stranded. Mechanic also informed me that it could also cause issues during driving not just when you stopped. The main warning lamp is the check engine light will illuminate and will throw a code for ECU not initializing.
