There are 50 owner-reported engine complaints for the 2019 Ram 1500in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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).
Camshaft and lifter failure As well as exhaust manifold leak
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 don't want him getting carbon monoxide poisoning.
The truck has a mild hybird 48 volt system that will cause the engine to stall in traffic.

UKNOWN ENGINE SIEZED WHILE DRIVING LOW OIL LIGHT CAME ON BRIEFLY BEFORE STALL. NO EVIDENCE OF AN OUL LEAK BEFOREHAND. TRUCK WILL NOT START.
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.
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 at 1045pm for a 3rd time INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
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. Excuse my French, but this is [XXX].also My truck would shut off while while driving INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
While driving down the highway the vehicle stalled out and quit running with no warning. Electrical error flashed on while trying to pull off to the side of the road safety. After getting it to a mechanic the cam was found to be bad.
2019 RAM 1500 Big Horn, less than 35000 miles and coolant leak from cylinder head.
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.
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.
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.
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.
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 is well aware of this but refuses to address it.
