2019 RAM 1500 Electrical System Problems

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...

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,...

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...

SEE FULL COMPLAINT NOTES IN ATTACHED PDF; SUMMARY HERE (you do not provide sufficient space to provide all info you request) I own a 2019 Ram 1500 4WD Limited (not eTorque). On multiple occasions, the vehicle has unexpectedly shifted out of Drive into Neutral while driving. When this occurs, a warning chime dings and a message on display directs me to “Shift to Park”. The vehicle immediately loses forward power (because it has shifted itself to Neutral), until I come to a complete stop, shift to Park, and then shift back to Drive to move forward. Usually the engine stays on, but on at least one occasion the engine turned off and I had to restart. This has happened at least five times total, including three times within the past month. The events have occurred while decelerating to a stop, braking but not stopping, and accelerating from a slow down. Each...

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

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

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...

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!

2019 Ram Laramie 1500 instrument or cluster panel goes blank or speedometer goes blurry and unreadable.

While driving a 2019 Ram I heard a winding noise then a rattling noise. I went immediately to the mechanic. He said it was my E-torque generator. He said I was lucky to get there because I could have had a complete loss of power or could have damaged other parts of the vehicle. A loss of power could be very dangerous on the highway possibly causing an accident or leaving me on the side of the highway exposing me to traffic driving by at 70mph+. The mechanic cannot get the replacement from RAM. Ram is not making them right now. There are over 5000 on back order. That means there are over 5000 people making payments on a work truck they can't use. Some people have been waiting for nearly a year.

Unknown; Stop/Start sends error and malfunctions.

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.

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.

Intermittent short discovered in the electric power steering (EPS) system. I took the vehicle to the dealership to perform diagnostic testing and the dealership confirmed the issue is a short-circuit within the EPS system. This issue has already been covered in a separate NHTSA recall (19E-077) however my VIN was not included. Amplifying information for this being a prevalent issue includes backorders from the OEM for replacement EPS systems, as well as multiple other sources online claiming to have similar issues.

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.

Problem Description: Beginning in early 2025, the vehicle started experiencing intermittent electrical malfunctions that cause it to lose power unexpectedly while driving. The issue occurs without warning, creating a significant safety hazard for both the driver and other motorists. The vehicle has been taken to an authorized Ram service center on four separate occasions (February 2025, July 2025, September 2025, and October 2025), but the problem has not been resolved. Each time, the service center has been unable to identify or repair the root cause. The vehicle is still under an active Mopar Vehicle Protection Plan (Account#[XXX]), and all service has been performed at Commonwealth Dodge in Louisville, Kentucky. Despite these multiple repair attempts, the truck continues to lose power intermittently, making it unreliable and unsafe to operate.

On [XXX}, the alternator went out on me 4 hours north of my home. I had it towed 30 miles to Canon Ram in Greenwood, MS. The check engine light came on about 20 miles before the issue escalated to the point where I had to pull over in a rest area and then completely died. The GPU alternator was not in stock and is reportedly on backorder; however, a recall was issued for the same item in previous model year Ram trucks. It's been 4 weeks with no date in sight for this being fixed.

I bought a new battery from the Chrysler dealership in February of 2023 that started going bad in May of 2025. It is under warranty until February 2026. On May 28th 2025, I was attending a canine seminar out of town. At the end of the day, I went to start the truck & the battery was dead. I was able to get a jump start & immediately took it to a local retailer to have the starter, alternator & battery checked.The battery had Indications of going bad, the alternator & starter passed the tests. I purchased a mobile jump starter to make sure I wouldn't be left stranded somewhere. When I returned home, I scheduled an appointment at the dealership to have them replace it. The dealership kept it overnight & said their diagnostic machines did not give the code that allowed them to replace the battery under warranty....

A cracked backlite frame resulting in an interior water leak (crack is visible from the outside). Water leaks from the top of the backlite. There is a recall under Warranty Bulletins: U.S. D-23-17 (TSB: 23-098-23) for the same make, year, and model as this vehicle, but it is not listed as a specific recall for this VIN. In addition to the risk of mold in the vehicle, electronics located below the leak, such as the RF Module beneath the rear seat, could also be damaged. This could lead to the inability to remotely start the vehicle, or even start it at all, due to the module being used to recognize the key fob before the vehicle starts. This could strand an individual and represent a safety concern in this aspect. The problem is well known on other vehicles; see the previous reference for Warranty Bulletins: U.S. D-23-17 (TSB: 23-098-23). However,...

While driving the truck completely lost all power and crashed into a side wall. Dealership stated it was an electrical issue related to steering brake rack.

Issue started with a "service shifter" warning at just shy of 3,000 miles, in January of 2019, and upon speaking to the dealership, they advised to shut off the truck and restart which cleared the "service shifter" warning. They said it was a glitch and that should remedy the issue. This issue became more frequent later (after manufacturers warranty ran out) It started leaving me stranded, sometimes for hours around 45,000 miles. Later, I suffered a multisystem failure and warnings that the truck was not in park, the shifter would not turn, truck would not start, and multiple other warnings. We were able to replace the battery which we thought had fixed the issue, but two weeks later it has done it again, and this time the battery disconnection for a period of days has not fixed the issue. I still owe two years on this truck and it has...

See attached document for complaint.

The eTorq generator stopped working and the engine shutdown on the highway. I had to get a tow to the shop as the vehicle is not usable and the engine will not start. Furthermore, this part is unavailable with no-ETA as it is on nationwide backorder. I have been waiting for over a month I was told over 13000 of these are on backorder for customers around the country. I have also read many posts of others waiting months for the part. There is obviously a systemic problem with the part and an issue with replacements. It does appear the original part was superseded by a different version. Please help!

MGU FAILED AND HAS BEEN ON BACKORDER FOR MONTHS

LCD screen in instrument cluster does not power on, stays black, and does not show relevant driving, safety, or error messages.

On August 20, 2025, my 2019 Ram 1500 Laramie was taken to the dealership for diagnosis after showing the warning “Electronic Stability Control system needs service,” along with a flashing check engine light. The dealer pulled diagnostic codes and documented U0403-00 (“Invalid Data Received from Anti-Lock Brake System (ABS) Control Module A”) as well as other communication errors. This is the same defect covered under Stellantis’ recall for ABS module failures that disable stability control in 2019 Ram trucks. However, my VIN is not included in the recall. A few years ago, the truck experienced the same warning, but the problem cleared on its own. Now it has returned and is documented with codes in the dealer system. The dealership acknowledged other recalls were already completed on my VIN, but refuses to perform this safety recall since my VIN is not listed. ABS and ESC failures are not the result...

MGU (alternator) has went out on my truck and multiple dealerships have stated they can’t fix it due to parts not available. Molar can’t get the part and now I’m stuck with no vehicle. The dealership told me they have multiple people waiting for the same part and that the MGU is faulty and fails on these trucks. My wife was taking my kids to school and they were stranded on the side of the road because my truck give a battery low warning and then died. It should be illegal for ram to continue to sell these vehicles and refuse to fix them. I can’t even buy a used part to fix it because the dealership won’t program and install a used part.

The MGU (motor generator Unit) is failing. Appears to be a known issue with Chrysler. Problem is that this part is not available. Was told that there are over 3,000 backordered parts with no eta. The dealer said that they had several on backorder from May. This is a 2019 product and there is no reason that this part should not be available.

After coming to a rolling stop and making a right, I would attempt to accelerate. The vehicle would then throw itself out of gear and I could not accelerate. A message would appear on the dash "Shift to P then Desired Gear." The problem would not be fixed until the vehicle was put in park, then back into drive. I took the vehicle to RAM and they could not replicate the issue, but it would happen to me regularly (1-2 times a month at random). I told this to RAM Dealership and RAM Cares, but nobody seemed bothered that it could get people killed. The problem did not seem to get fixed until I took apart the throttle body and cleaned it out by hand. Since then, I had not had an issue.

At about 77k miles, I started hearing a humming noise from the engine when I would accelerate and then decelerate. Upon inspection and confirmation from Ram dealership, the Engine Generator Kit (alternator) appeared to have a bad bearing and needed to be replaced. I initially agreed to the replacement until I was told that the part needed is on backorder and that there were roughly 4k orders placed ahead of mine nationally. This means I have no way of fixing this issue using an original MOPAR part. I was told I can agree to pay for the item to get the order placed and then wait until it comes in with no timeframe given other than it could be weeks or months. I am now having to drive around in a vehicle that could potentially breakdown at any time and thus leaving me with no vehicle. I do not have...

Mopar Part # 68623194AB Generator on a national backorder. There is a problem with this part and MOPAR cannot fix the issue - ETA is non existent - Truck has been parked since July 4. Making payments on a truck that is not functioning. The vehicle shut down completely on I-95. Had to have it towed to my home.

The contact owns a 2019 Ram 1500. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated on the instrument panel. The contact pulled over to the shoulder of the roadway and turned off the vehicle. While attempting to restart the vehicle, the vehicle failed to immediately restart, and several attempts were needed to start the vehicle. The vehicle then returned to normal functionality, but the failure became a regular occurrence. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The contact was informed that the failure had been referred to an engineer with the manufacturer. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 45,000.

The alternator part has been out of stock since the beginning of 2025 my trucks alternator went out in March and have not been able to find the part available for purchase, it has been 5 months.

The truck lost power steering due to the soldering on the star connecting being messed up. The truck also had 4x4 not available,as well as no brake assist in reverse due to the communication issue. The dealership had to replace the star connector due to soldering issue.

The contact owns a 2019 Ram 1500. The contact stated that while his wife was driving at an undisclosed speed, the left turn signal failed to engage as intended. Additionally, the contact stated that the instrument panel displayed that the right turn signal had engaged independently while driving. The vehicle was taken to an independent mechanic, where it was diagnosed that the steering wheel module had failed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

The "Generator Kit" which houses the vehicles alternator went bad. I have been waiting for more than 4 weeks for the repair to be done and the shop has no idea when the part will arrive. It is Generator Kit #68623194AB. I reached directly out to 12 dealers and none of them give me any idea of when they can get the part and have a waiting list themselves. The web is lighting up with thousands of complaints about this single issue. One dealer said they have no idea when the part will show up and they've already been waiting for "6" MONTHS. They said it could honestly be another 6 months. For an alternator??? RAM Trucks has a major issue here and they have known about it for a while.

When using reverse, the image stays on the screen in reverse for sometime. also, screen stays a solid color in black or blue at times not allowing any controls on the screen when attempting. Screen will sometimes freeze and reset sometime after driving. radio and or screen stays on for an extended period of time after turning vehicle off leaving vehicle and locking doors still allowing radio/screen to continue in operation.

[XXX] Known issue in 5th Gen Ram 1500s. Defective Mopar Connector Cam Buss. Causes the truck shifting problems and can cause going into park while driving. Issue below is on the forum causing a wreck. My 2019 Dodge Ram Limited started malfunctioning, causing me to wreck when the shifter unexpectedly went into park while I was driving. The brakes locked up, making the truck slide, and by the time it switched back, I was already sliding off the road. Parksense unavailable warning & service Shifter lights do come on. I called the Murfreesboro Ram dealer and they confirmed the issue that is was known to dealers. Majority of the dealers are sold out of the part due to this issue.

Rear window seal has allowed water in to the cab of the truck and the electronic components under the back seat have already had to be replaced causing the vehicle to not operate properly. The rear window is still leaking and has leaked since 2021, when it was replaced under warranty. If water enters into the electronic components under the back seat or the air bags located in the head liner, while driving, this could cause severe damage to property and could be harmful to life.

E torque alternator generator failure, loss of power while driving to all vehicle electrical systems. Part is on national backorder. Reading forums this has been an issue with ram on failure and backorder issues for over a year.

The alternator failed suddenly and without warning, leaving me stranded on a road with no shoulder during 91°F heat. The vehicle lost electrical power and required a tow. This is not just a standard alternator,it’s a component of the eTorque mild hybrid system and requires both a specific part and a dealer reprogramming (flash) to function. After the incident, I learned that the part is on national backorder with more than 4,000 vehicles waiting, according to multiple dealers and service centers I’ve contacted. Ram has provided no reliable ETA, loaner, or support option. This is a critical failure that completely disables the vehicle and creates a dangerous safety situation, especially in high temperatures or in areas where pulling over safely is not an option. I was without air conditioning or any form of engine power while exposed to traffic and heat, and had to wait a prolonged time for a...

I was at a stop light and I got a warning light and a check engine light that said service shifter. After that, it wouldn’t shift gears and I was stuck in 1st gear. I pulled over and got a service tire pressure light, 4WD temporary unavailable light, service airbag light, ESC light, parking light. The vehicle was also sputtering and the cooling fan came on full force.

Our screen turns black, the heat is activated and the windows lock. Dash notifications for ABS flash along with others including blind spot notifications. This occurs while driving. This is a major distraction and concern.

The PCM has completely shut down, the truck has 50k miles, has been serviced regularly, and is in excellent condition. 2021 and newer models have been recalled due to the same issue but not 2019.

The MGU has failed. The truck is undriveable. It was diagnosed by Ram dealership.
