2019 RAM 1500 Engine Problems

The exhaust manifolds crack both of them which is a flaw that has not been recalled The leak started within a few months of owning the truck new it was under bumper to bumper warranty but the leak was not loud so I did not worry about it and it always passed emissions after the manufactures warranty was up i bought an extended warranty and it ran up still passing emissions, the truck got to about 110,000 miles I have never had to fix anything but battery, tires, and oil still passing emissions. The leak started getting louder especially with a cold motor and startup fuel milage has decreased and most importantly exhaust would come into the cabin during ideal so, if I'm in heavy traffic or stopped at a light it gets hard to breath I had to replace the exhaust manifolds because I take my grandson sometimes and...

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,...

For about many months now I have had what sounds like a Exhaust Manifold leak. I have been trying to learn more about it. I have a 19' Ram 1500 Laramie and I have found that this is an incredibly common issue amongst Ram owners with a 5.7L V8 Engine. You tube has thousands of videos about how to repair, there are hundreds of message boards online, and even my mechanic said to me "Oh yeah I've fixed hundreds of this issue on Rams". When I remote start my truck I have to roll the windows down when I get in to let the exhaust smell out of my truck. I would assume that the air intake for the cabin climate control is pulling in the fumes from the engine bay. It concerns me to leave my truck run too long while not moving for fear of passing out. When...

The truck has a mild hybird 48 volt system that will cause the engine to stall in traffic.

The 3.6L Pentastar V6 oil filter housing assembly (found on 2011-2023+ Jeep, Dodge, Ram, Chrysler) is a common failure point where the plastic housing cracks, causing oil leaks, coolant contamination, and overheating. Replacing it with an upgraded aluminum unit is highly recommended for durability. The assembly is located under the intake manifold and requires removing the upper intake plenum and several components for access. Key Details for Replacement Common Failure: The OEM plastic housing becomes brittle from heat cycles, leading to oil/coolant leaks in the engine's valley. Upgrade Option: Upgrading to an all-aluminum housing prevents future cracks. Required Parts: New assembly (e.g., Dorman 926-959, 926-876 or Mopar 68596317AB/68596318AB), new O-rings (should be included), and new intake manifold gaskets. Process: Requires removing the upper intake manifold, removing the old housing (held by 5 E8 Torx screws), and cleaning the engine valley before installing the new unit.

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!

My 2019 RAM 1500 diesel (built 12/12/2019 is included in Recall 23V-411 for tone wheel delamination. My tone wheel has failed (confirmed by technician). Stellantis provides free tone wheel replacement under Recall 73A for 2014 and 2016 models but excludes 2015/2017/2018/2019 models despite having the identical defect from the same supplier. I received only Recall 66A (software) which did not prevent failure. Stellantis now wants me to pay $3,037 to replace the defective part they replace free in other model years. This discriminatory recall remedy is inadequate and unjust.

The contact owns a 2019 Ram 1500. The contact stated that the check engine warning light had illuminated. Additionally, the contact stated that while driving, the throttle sensor warning light illuminated. The contact stated that the failure had recurred while driving. The vehicle was taken to the dealer where it was purchased, and the light was reset; however, the failure recurred. The contact stated that while driving 45-50 MPH, the failure recurred, and the vehicle stalled. The contact was able to pull over to the side of the road, but the vehicle failed to restart.

Oil pan completly rusted through .I have lifetime warranty they say not covered because of rust.Its all over the ineternet that 2019 ram 1500 had a bad batch of oil pans.If the oil leaks out the engine will seize and cause me to crash.

After starting the 2019 Ram 1500 Bighorn in the morning, or after starting the truck and putting it in Drive, the vehicle sometimes shifts itself from Drive into Neutral as we come to a stop. When this happens, the gear indicator on the dashboard begins blinking and displays the message: “Shift to P then desired gear.” On one occasion, as my wife was merging onto the freeway in front of an 18-wheeler, the vehicle suddenly went into Neutral as she slowed down to merge. When she pressed the gas pedal, the truck did not move, putting her in immediate danger and forcing her to coast while traffic approached from behind. This issue has made the vehicle unsafe to drive because it can unexpectedly drop into Neutral at critical moments for example, while crossing lanes, merging, or pulling into intersections. There are no warning lights or alerts before this occurs. Sometimes,...

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.

The contact owns a 2019 Ram 1500. The contact stated that while driving 45 MPH down the road, the brakes unintendedly activated, and the vehicle stalled. The vehicle was towed to a mechanic who was unable to retrieve a fault code. Several unknown warning lights were illuminated. The vehicle was towed to the local dealer, where it was diagnosed, but the dealer was unable to determine the cause of the failure. Upon additional research, it was determined that the recall was completed under NHTSA Campaign Number: 24V653000 (SERVICE BRAKES, HYDRAULIC, ELECTRONIC STABILITY CONTROL (ESC), but the update was not performed, completed, or done correctly. The vehicle was repaired. While driving at an undisclosed speed, the power steering became inoperable. The vehicle was towed to the residence. Upon investigation, the contact located a Class Action Lawsuit. The local dealer was contacted, and it was diagnosed that the power steering module needed...

Exhaust Manifolds are cracked as others have noted. This a known issue by the manufacturer and they have issued a TSB but those of us out of warranty have to pay to replace their known defective part. This should be a full recall.

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...

Alernator / generator failure. shutdown engine while driving on the highway. Steering and breaking ability severely reduced.

I’ve had this car for four years and my motor has blown three times and they have changed the head on the motor three different times I was driving the car on the highway. The car was at the dealership for five months and the day I get the car back not even eight hours later I’m driving down [XXX] other car shuts off and says to put in park and leave me stranded on the side of the road with my [XXX] child and my girlfriend . I had to wait until they came and picked me up and told me and this is extremely unsafe and a hazard after the third head replacement at the dealer and the car still under warranty. I don’t feel safe in this car with My Child. I picked up my truck around 2pm August 25th , and the motor blew Wednesday night...

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!

Exhaust manifold bolts on the passenger side of the vehicle (2019, 5.7 Hemi, Larami version) have broken. The exhaust system is leaking. An exhaust smell and taste is readily detectable when standing near the cab doors of the vehicle. There is an unknown, regarding if any amount of the exhaust is being drawn into the cab air intake.

EGR cooler has failed and leaked on manifold after 2 EGR bypass cooler replacements. Went online to see when original EGR recall was completed and online data base reported complete Dec 29, 2019. That particular part for the VB1 was not even ready until March-May 2020. There are also no service records or work order for that recall being completed whatsoever. The EGR cooler cracked on the manifold while driving with my kids and almost or did ignite as the whole truck was pouring smoke from behind and underneath. The dealer did inspect and confirm the damage and has been in touch with the manufacturer, acknowledges that there are no service records or work orders for that recall. Dealer acknowledged that no part was available. Manufacturer takes no responsibility but did state in e-mail they believe recall was claimed to have been done in transit during a stop sale.

I have a 2019 Dodge ram 1500 has 77,000 miles on it. My alternator generator went out. I’ve called over 100 places and no one has the part so that leaves me stranded for work because I own a business I’ve had the truck for five months. And I’ve read that many people are having the same issue.

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.

In November 2024, my 2019 RAM Rebel displayed “SERVICE SHIFTER,” “PARKING ASSIST,” and “CHECK ENGINE” lights. Dealer performed software updates, but one week later the lights returned. Dealer then replaced the parking assist module, but two weeks later the same issue happened again. I have brought the truck in multiple times since. Often the lights turn off before arrival, and dealer states no fault can be detected. I was told to bring it in immediately when the lights are on, which I did, but still no fault found. Problem continues, and now the truck has begun putting itself into park while driving or when stopped. This is an ongoing and serious safety hazard. I also added photos of others affected by the same issue.

[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. Charging $200 in labor for a simple 10 min swap out of electrical part. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I brought my truck in because the check engine light was on. My mechanic first replaced the oil pressure sensor, but the check engine light came back on. The oil pressure is low, and the oil pump is the problem. I only have 62,000 miles on the truck, and have kept up with oil changes and maintenance.

As we were driving and pulling a 32 foot trailer battery died, luckily we were able to stop safety and charge battery and bought a new battery to get us home. The Mopar 48‑volt motor‑generator unit (MGU)—often referred to as the “eTorque alternator died. There is a back order of currently 4800+ and months to get this part in order to fix a truck that doesn’t start without it. How is this not a recall? This is highly unsafe if we hadn’t been watching the battery voltage as we were driving and noticed it was getting dangerously low potentially causing a huge pile up accident on the freeway with our trailer.

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.

Engine failure with no warning — cylinder #7 collapsed, pushrod broke, and exhaust manifold cracked at only 68,000 miles. This is a known issue with 5.7L HEMI engines, particularly involving defective lifters and camshafts. These failures can result in total engine loss, potential stalling at speed, or permanent engine damage. I am reporting this due to concern over the growing number of similar failures in Ram trucks with low mileage, which may indicate a design defect. FCA/Stellantis has denied goodwill assistance despite low mileage and well-documented cases. This could be a safety issue if engine failure occurs while driving. Please investigate.

Valvetrain and camshaft failure causing misfires in the engine. Safety related issues are possible stalling, overheating, or loss of power can lead to accidents, injuries, or even fatalities. Engine problems can also affect other crucial systems like braking and electronic stability control, further increasing the risk. The stellantis service bulletin B09 FSAR-TSB-5485 clearly shows that their malfeasance across multiple years and vehicle makes, Are not only causing consumers financial burden but could lead to serious physical burden if something happens while driving. My Ram 1500 is in the shop being checked by my own mechanic my check engine light came on which prompted me to get it checked but my mechanic has informed me that the code being thrown is only reading for cylinder 4 and that the entire side of 2, 4, and 6 are misfiring because of this issue which is giving misleading codes.

While changing the oil in my truck I noticed that the oil pan was severely corroded, I mean badly. I looked around under the rest of the truck and there really wasn't any corrosion anywhere else that I could see. I looked online and found out that this is a huge issue with these types of vehicles and the corrosion will get so bad that the vehicle will weep oil which puts the engine at risk but is also horrible for the environment. I took the truck to the dealership and the service manager explained to me that they are well aware of the problem but Ram refuses to do anything about it and claims it's caused by environmental factors. Funny how those environmental factors only affect the oil pan and nothing else on the truck. As I stated, this is a huge potential issue for the environment because Ram...

Truck was stopped. Then as I started pressing on the gas pedal, there was a warning sound. The gear selector knob rotated on its own from D to P and the message on the screen said to start / stop the vehicle to put it back in gear D. This put myself and my family at risk of a car accident as we were merging onto an expressway. This happened while the truck was starting to accelerate. This is the second time this happens.

My 2019 RAM 1500 Big Horn/Longhorn 3.6L V6 (VIN: [XXX] ) experienced a sudden and catastrophic engine failure without warning while driving. The vehicle shut off unexpectedly on the highway and would not restart. There were no prior dashboard warning lights, low oil pressure indicators, or error messages before the incident. A full diagnostic revealed severe mechanical failure in cylinder 1, including piston-to-valve contact and 40% leak-down with compression at 50 psi. This damage rendered the engine inoperable and required a complete replacement. Prior to the failure: The vehicle was regularly maintained using synthetic oil, following the manufacturer's recommended intervals (between 6,500–10,000 miles). The oil life indicator was followed, and the truck was never low on oil or pressure. A Customer Satisfaction Notification for PCM (Powertrain Control Module) reprogramming was never completed due to the dealer’s system being down on two separate service visits. Despite following proper maintenance and attempting...

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...

I am filing a formal complaint regarding a critical safety defect in my 2019 Ram eTorque, which posed a severe risk to my pregnant wife while she was driving. The vehicle’s battery unexpectedly failed, resulting in a complete loss of power steering and all safety functions, creating a hazardous situation in the middle of the roadway that could have led to a serious accident. This defect is not isolated. My truck has been at the repair shop for over two months, as the necessary replacement part is on backorder due to over 3,000 reported vehicles affected by the same issue. The widespread nature of this defect and the unavailability of parts amplify the risk of injury or fatality to drivers and passengers. I urge the Safety Advisory Board to investigate this defect urgently, focusing on the significant safety implications and the high number of affected vehicles. Immediate action is needed...

Smelling antifreeze coolant inside the cab while driving. Fumes are not safe to breathe and vehicle could overheat and cause engine failure stranding driver and passengers. Appears to be common based on Internet research.

Bad Cam Shaft and lifters on 2019 Ram 1500 3.7 liter 6 Cyl. Have been told it is a timing issue. Check engine light is on. Have been told by dealer not to drive long distances and that the engine could shut off while operating the vehicle. Parts are back ordered through dealer. Have waited at least 1 month but no parts are available. Understand this to be a common issue with this specific vehicle and engine. It's an expensive repair.

The MGU has failed just outside of the 80,000mile warranty. Looking online the MGU failing seems to be a big issue and the manufacturer doesn’t have parts stocked so it takes a month to get a new part. The cause is manufacturers defect

Engine failure after fuel pump recall replacement(37,500 miles). My fuel pump had a mandatory recall. I drove my truck in and everything was running perfect. I drove the truck less than 100 miles after the fuel pump replacement recal and it started to make nocking sounds and the gas was lagging , not accelerating normal. The gears were not shifting normal but rather jerking in and out of gears at different RPM's. I was on the highway in CA and I was scared that I was gonna hit someone or be hit myself from the gas lag and jerky shifting. I drove back into the dealership again 100 miles after the fuel pump replacement. I was charged $288 dollars for them to tell me I needed a new engine. No engine lights or warnings. Now 100 miles after the fuel pump replacement and 2 months out of warranty they wanted...

While driving down a curving mountain highway above 70 mph, the gauge cluster displayed “shift to park” or “shift to drive” I don’t recall exactly. The transmission then downshifted dramatically, perhaps into 3rd gear, then the motor shut off.Thankfully, I successfully merged through heavy traffic to the narrow shoulder but the truck would not restart. After over 30 minutes of attempts (fuel tank above half)I called a tow truck. My family climbed up the hill to get a safe distance from the road. It was cold and dark and things could have gone much worse. Ram owners on internet forums have described this exact problem many times and it’s clear that this is a wide spread safety issue. This is the second time the truck had lost power while driving in the same manner. The first time the dealer could not replicate the issue while it was under warranty and...

My alternator went out driving down the interstate. No indication that it was bad up until it died. Has been sitting at a dealership for about a month due to this particular part having almost 3000 on back order.
