2019 RAM 1500 Problems

The contact owns a 2019 Ram 1500. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated shortly afterwards. Several unknown warning lights were illuminated. The contact stated that the transmission failed to shift out of first gear. The message “Slow Down - Service Shifter” was displayed. The contact associated the failure with TSB: (23-029-22 Rev. A); and referenced an extended warranty coverage. The vehicle was taken to a local dealer, where it was diagnosed and produced DTC: U0645 - Lost Communication with Active Air Dam Module. The vehicle was not repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 137,700.

When driving, I get a prompt on my dash to switch to park and then desired gear. I get no response from my accelerator until I do so. This particularly happens when I’m slowing down and accelerating after a stop signs or traffic lights. Happens while in the middle of intersections. This happened about 7 times in the past month. Dealership said they couldn’t find a problem when I took it in. They did a transmission re-learn which I paid for and the issue happened twice since that appointment.

​SUMMARY OF ISSUE: Water intrusion from a defective factory rear window seal flooded the Radio Frequency (RF) Hub module, causing severe, dangerous network communication (CAN bus) failures while driving. The removed RF Hub has been retained by the owner and is available for physical inspection upon request. SAFETY RISKS: Power steering repeatedly seizes/locks up while driving. ​Vehicle completely stalls and freezes in active intersections and at highway speeds on I-95. ​Instrument panel illuminates with all warning lights ("Christmas tree" dash) and prompts driver to "Put Vehicle in Park and Put Back in Drive" while actively moving in traffic. ​Vehicle experiences complete power loss, creating a severe rear-end collision hazard. ​TIMELINE & MILEAGE: 60,328 mi (Dec 2022): Initial electrical glitches reported to dealer prior to 100k warranty expiration. ​92,733 mi (Sept 2024): Reported ongoing key fob loss, electrical anomalies, and TPMS drops. ​168,492 km (~104,696 mi): Scanned multiple CAN bus "U-codes" (documentation available). ​104,716 mi (Sept 22, 2025): Leaking rear window seal repaired by dealer. ​~114,000 mi: Worsening symptoms and total vehicle stall. ​DEALER FAILURE & DENIAL: When repairing the window seal, the dealer failed to inspect for interior water damage or check underlying electronics. They refused to open/inspect the RF Hub, claimed they could not reproduce the intermittent issue, and are attempting to blame an unrelated "star connector." The owner opened the RF Hub casing and photographed clear galvanic solder corrosion and water damage directly under the leak point. Component has not been inspected by police, insurance, or manufacturer reps. PRIOR SYMPTOMS: Progressive TPMS loss, "Key Fob Not Detected" while driving, throttle surges at stops, parasitic battery drain, and full dash light warnings—worsening with humidity and rain.

I was on the highway when the vehicle alerted me that shift was unavailable then the auto start/stop was unavailable then the airbags were unavailable then my FUEL and my MPH were not reading. My windshield wipers started all on their own and could not be turned off! And my EMERGENCY LIGHTS WERE INOP. I LOST POWER STEERING and was locked in gear! All while in morning rush hour traffic on the highway! The vehicle gave me a notification to get to my destination before turning it off or changing gears because it would not go back into gear. I got off the highway as safely as I could without EMERGENCY LIGHTS OR TURN SIGNALS and proceeded to a stop light. While slowing down I had no steering control. I pulled over and had to force the wheel to turn then I attempted to accelerate to move and had no power. So I was stuck. I had emergency services come and tow my vehicle to Chevrolet of Homewood at that point who is currently looking at it.

019 Ram 1500 5.7L eTorque MGU (Motor Generator Unit) failed on 08/29/2025 at 62,105 miles. Vehicle died on road and would not restart, creating a safety hazard. Dealer confirmed battery was severely discharged due to MGU failure — alternator was not putting out voltage necessary to charge battery, resulting in failed MGU. Vehicle was inoperable for 109 consecutive days (08/29/2025 through 12/16/2025) due to Stellantis parts backorder with no ETA provided. MGU is covered under Federal Emission Warranty (8 years/80,000 miles) per FCA US LLC 2019 Ram 1500 Warranty Booklet Section 5.1B. Stellantis denied all warranty obligations and failed to respond to a formal $40,125.00 certified mail demand for consequential damages. This defect is subject of active class action litigation: Fisher v. FCA US LLC, Case #2:23-cv-10426, E.D. Michigan

Pop up display indicates ABS failure, There exist already active recalls on 2019 Ram however according to Ram Customer Service my vehicle is not among current recalls. My issue is the same as my nephew. ‘Same truck, same year, . ABS failure , disables cruise control, 4 wheel drive, and says to have system serviced.

The ABS control module and Hydraulic Control module are faulty and available for inspection. My safety is at risk because the vehicle will go into a skid upon hard braking (ABS not fuctioning), the vehicle will spin tires upon acceleration (traction control inoperative). The above listed components have been determined faulty by both the dealership and an independent service center. The component is on national backorder (according to the dealership) due to how common this issue is. The ABS, traction control, and brake light stay illuminated as well as the dashboard "message center". I'm in disbelief of there not being a recall for something so dangerous. I travel for work and tow my travel trailer and now am unable to do so safely. The fact that the modules are on backorder is a testament to how common this issue is.

Whenever I refuel my truck the pressure in the fuel tank causes fuel to spit out of the fill neck. It is a common, known, issue among RAM trucks involving the fuel line. It takes me 20 to fill the tank up because of this issue, and I’m constantly having the fuel spitting out at me and the ground. This is a safety/fire hazard that needs to be addressed by RAM. Apparently the only fix is to replace the entire tank which is costly and frustrating. RAM acknowledges this yet they won’t fix the issue, and requires the owners to pay out of pocket to fix this. Being a safety hazard they should be on the hook for the cost. Thought it was a minor issue for a while that would only happen on occasion , but now it’s happening every time I try to fill. That’s when I did the research and found this is a normal issue. The dealer wants to charge me just for them to diagnose the issue before they will repair it.

On March, while I was leaving to take my children to school, I discovered a loud, heavy metallic knocking sound coming from the engine of my 2019 Ram 1500 Classic. As I depressed the gas pedal, the knocking frequency increased immediately with the engine RPMs. Prior to this total failure, I had noticed the truck feeling hesitant and "stuttering" when I was trying to accelerate from red lights in the days leading up to the incident. ​Because I was concerned the engine would stall or fail completely while my children were in the vehicle, I immediately stopped driving it. A subsequent inspection at Don White’s CDJR confirmed DTC P051B-00 (Crankcase Pressure Sensor Performance). This fault is a recognized indicator of excessive crankcase pressure, which NHTSA has identified as a precursor to sudden engine stalling and fire risks in 3.0L EcoDiesel engines (Ref: Recall 19V-757).

The passenger airbag in my 2019 RAM 1500 (VIN: [XXX] LP: [XXX]) is completely missing. The dashboard was cosmetically repaired to hide the absence, and the warning light was tampered with so no airbag/SRS alert appears. This was only discovered during a recent inspection; I had no prior warning. Inspection by an independent service center is scheduled and I can provide the vehicle for examination upon request. This creates a severe safety hazard, for years I've driven with no passenger airbag protection and false reassurance from a working dashboard. The issue was not disclosed by the selling dealer. I have photographic evidence and can provide all records upon request. Problem has not been addressed by the manufacturer, dealer, or police/insurance representatives yet. Safety of all occupants was unknowingly put at serious risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My sun visors on both the driver and passenger side have fallen down numerous times. When they fall they end up dangling in front of my eyes (more so of course the driver's sun visor). In addition it is an instantaneous alarming moment and when in busy traffic and all of a sudden this suddenly happens and I cannot see it becomes dangerous. I have found out talking to my dealer and online that this is a very common problem on the 5th generation Ram 1500 pickups.

Driver's side visor fails to stay in place in the ceiling when moving it from front windshield to door window, then after several movements, will fall out of place in the roof into the driver's view without warning obstructing view while driving or startling the driver which could cause an accident. The visor has been replaced once, from the same issue and is now having the same issue again. The visor is available for inspection and still has the issue. The dealer knows there is a problem and has given me a number to order a third visor. This all happens without warning and always while the vehicle is in motion.

Manufacturing defect in the rear window frame (Backlite) causing severe water intrusion. Water is pooling directly onto the RF Hub (Radio Frequency Hub) electrical module and wiring harness. This creates a high risk of unintended vehicle shutdown while driving or a total electrical short-circuit/fire. This is a known issue documented in TSB 23-016-21 and Warranty Bulletin D-23-17, yet the manufacturer is refusing to honor the 8-year warranty extension for my specific VIN despite the safety risk.

1 The vehicle’s dashboard upper trim panel (leather covering and stitching) has failed. The leather is lifting and separating from the dashboard surface, and the stitching is coming undone. The vehicle is available for inspection upon request. 2. The lifting and peeling leather creates a safety concern. The leather separation is present at all times and continues to lift from the dashboard. The condition becomes significantly worse during hot and humid weather, as the material expands further. This can obstruct the driver’s forward or peripheral vision, including blind spots, reducing the ability to clearly see passengers, other vehicles, or road hazards. Additionally, if the material continues to detach, loose sections could interfere with steering wheel components or dashboard controls, creating a distraction or potentially affecting safe vehicle operation. 3. Yes, the issue has been inspected and confirmed by a dealer. The dealer acknowledged the dashboard leather separation and stitching failure. Similar issues have also been reported in other vehicles of the same make and model. 4. The issue has been inspected and confirmed by an authorized dealer. It has not been inspected by police or insurance representatives. The manufacturer has not directly inspected the vehicle at this time. 5. There were no warning lamps or dashboard messages prior to this issue. The first symptom was visible lifting of the leather and loosening of the stitching on the dashboard. The condition has progressively worsened over time and becomes more pronounced during hot and humid weather, although the separation is present regardless of weather conditions.

On or around March 12 2026 The drivers front tire air suspension and compressor both went out causing tire to drop which meant it was rubbing the finder well it has been taken to a dealership and confirmed No warning lamps or warnings visible to me appeared on the truck just noticed the change in how it was driving and noticed the significant drop in tire

Air suspension keeps failing in cold weather.

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.

Driving 60mph in 8th gear while raining, 40 deg F, in Minnesota. The truck shut off (I did not press the Start/Stop button) and dash said "Vehicle Not in Park." Went to pull over, put on turn signals, but they didn't work (it acted like the vehicle was completely shut off but was still rolling at 50+ mph in 8th gear - there was no indication on the dash that showed green light indicating turn signal was working). I suspect brake lights also did not work at this time, but cannot confirm because I couldn't see them. I pulled over to shoulder, slowed to a stop, and put vehicle into Park manually. Pressed Stop/Start button and vehicle started. No codes were thrown. Drove another 2-3 miles and similar issue happened again. Display flashed on and off (then completely turned off) when coming to a stop this time. Vehicle stayed running but again said "Vehicle Not in Park" on dash. No other indication on dash (no warning lights). Drove vehicle back to dealership to get inspected. Similar issue occurred 4 more times on the 12 mile drive to dealership. When I got the vehicle into the service shop, I put it into Park, then pressed the Start/Stop button, but the truck would not shut off. I left the vehicle with the dealer and they are currently diagnosing the issue. 105,000 miles on vehicle. First time this issue has ever occurred on the Ram since I bought it used with 67,000 miles on it. Scared the heck out of me - I had cars swerve around me as I pulled off to the shoulder without any indication - no brake lights (I assume), no turn signals. Very scary. I am worried about driving my family (wife and 2 young children) in this vehicle. What has scared me even more is I looked up this issue online and I have found 100s of examples in the forums of similar (or exactly the same) issue happening to them! I have had all recalls completed on my truck and keep meticulous care of it. I am an engineer and understand technical details well - this electrical issue scares me. Not safe.

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.

The contact owns a 2019 Ram 1500. While driving at an undisclosed speed, the sun visor frequently fell, obstructing the driver’s view of the roadway, creating a safety hazard. The vehicle was taken to a dealer for inspection, but the vehicle remained unrepaired. The manufacturer was notified of the failure. The failure mileage was approximately 71,000.

Car accident. Repaired tires due to abs. Also backlite repair. Leaking water.

Initially while taking a corner at low speed the truck made a clunk and grinding noise which resolved and then while going about 50 mph the grinding noise recurred which prompted stopping the vehicle on the side of the road and when almost to a stop, the wheels locked up causing a slight skid; the vehicle was in 4-wheel auto at the time and with change between 4wd and 2wd serveral times the front tires unlocked and i was able to drive it again. About 4 days later, while driving 70 mph, the vehicle started to make a grinding noise on the interstate, and I started to slow down, but unfortunately, I was on the left side of the highway on a narrow shoulder, and upon getting to a lower speed while in 2WD, my front axle locked up. I placed the vehicle in park, but due to safety concerns, I put the truck back in drive and tried to switch from 2WD to 4WD to unlock the axle, but unfortunately, the truck would not change gears. I then had to quickly get the vehicle to the other side during a time with fewer vehicles, while the left front tire was locked, and I had to drag it across the highway to ensure my safety. The left front tire remained locked, and after multiple attempts, the brake partially unlocked but continued to make a grinding and clunking noise. After some diagnostics, we determined the left front wheel hub was the issue, overheating and locking up. I reached out to mechanics for quotes on repair of said part, and upon reaching out to the dealer that I have used in the past for recalls and oil changes, I was informed there was a recall on said part/software that I was not aware of; the service rep used the last 8 of my VIN to look up my vehicle for the quote and provided the details about the recall. I use the RAM Guardian App which provides updates about recalls and upon checking it does not show a recall nor does it show a recall when i search my VIN and License Plate on the website. This seems to be a common issue based on customer reviews.

The contact owns a 2019 RAM 1500. The contact stated that when his spouse started the vehicle during cold weather conditions, the engine was turned on, revved high, and the gear shift from park (P) to drive (D) inadvertently without the brake pedal being depressed. The contact stated that the vehicle jolted off and crashed into the door of a business. The contact's spouse sustained a head injury but did not receive medical attention. A police report was filed, but the info was not readily available at this time. The vehicle was taken to the spouse's residence and parked. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 100,000.

The contact owns a 2019 Ram 1500. The contact stated that while driving on the highway at 60 MPH the messages "Service Air Bag System", "Service Electric Stability Control", "Service Trailer Brake System", "Service Park Brake", "Service Anti-Lock Brake System" and "Service Power Steering" were displayed and several unknown warning lights were illuminated. The contact stated that soon after, the transmission failed to shift into gears as intended, and the vehicle lost power steering functionality. The contact also stated that while driving and making turns the transmission will slip into neutral(N) upon depressing the accelerator pedal. The contact stopped the vehicle, shifted to park(P), shifted back to drive(D) and drove to the residence. The vehicle was towed to a local dealer, where it was diagnosed that the Electric Harness and RF Hub had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage approximately 154,000.

I was driving down a road with no load on the truck at about 35 mph. The front tire blew out. Stopped immediately. The tire had torn all the way across the tread from outside of wheel to inside of wheel. See attached pics. I had a former goodyear employee look at it and he said he thought it was defective. If this had happened at higher speed could have been very bad, could have killed me or others. As it was the tire caused over $2000 damage to the truck - inner fender well and fender etc...These were original tires that came on the truck new had about 31,000miles on them. Still have the tire and it can be inspected.

going down interstate 70 miles per hr no obstructions at all tire blew out kocked fender out of position and tore off wheel well linning big hole all the way across tire
