2019 Ram 1500: engine overheating

Filed May 7, 2026 · Brakes, Wheels · CO

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 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.

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.

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 $22,000 to replace my engine. They said they would do me a favor and replace it for $4300 since I was 2 months and 1500 miles past my warranty. Now I'm left without a truck 100 miles after the fuel pump replacement. I couldn't afford a rental car and they didn't have any for me to rent at the dealership. I was soon fired from my job as I was scrambling to find $4300 just laying around. Now I don't have a job and $4300 plus $288 in debt on my credit card at 22% interest. These same fuel pumps have already had class action lawsuits on them for earlier models. Metal shavings were being produced within the fuel system. The other problem being reported was over heating from the connector rod to the crankshaft. The connection was overheating and causing bearings at the connection to fail. Once that happens 1 or more cylinders stop pumping correctly and the engine blows. So there are 2 possibilities for this engine failure. I am certain that my car was damaged by 1 or both of these poor engineering mistakes. They could have hurt or killed someone and they are hiding the real problem until they get caught.

Vehicle behaved erratically before repair and still does. It seemed a bit better after the repair but issues are still there. It lurches forward when coming to a stop and accelerates in a delayed manner, starting slow and then jumping forward. The 4 wheel drive issues system errors like overheated and function diminished. At times it just doesn't work. Systems turn themselves on. (axle lock) These issues existed since the vehicle was new with the dealership telling me they didn't know what could cause them.

Air suspension failure on front drivers side 2019 Ram Rebel. When it was below freezing outside, a warning message flashed across the screen saying service air suspension immediately. Went home and got up later to drive again and the warning message was gone, never to be seen again. Fast forward and it was extremely hot out. Noticed the truck was leaning to one side. Jumped in, started it, and the height recentered. Got out and could hear an active air leak. Drove for a while and would always raise and lower as normal. Issue seemed to go away. Finally, it came back. When trying to change the heights, a message flashed that said “Air suspension system overheating. Ride height safe to maintain.” Sent to dealership. Took 2 days to find issue. Mopar gave oddly specific instructions to determine if that was the issue. Air suspension replacement cost $2500 and not covered under any warranty. Took almost 2 months to get the part. National shortage of the part. Was told driving to vehicle was a safety concern because if the motor in the suspension failed, it could cause the vehicle to rapidly fall, causing loss of control and airbag deployment. Ram refused to call back when trying to get answers about what was going on. Dealer contacted other dealerships and parts places across the country to no avail. When the part came unexpectedly and I picked up the vehicle, I was informed that another 2019 Ram Rebel was there for rear air suspension failure with the same issue of inability to locate a part.

Vehicle 4WD functionality. Vehicle fails to engage 4wd system. If 4wd does get engaged and used, it will say “4wd overheated” and “service 4wd system” and no longer engage 4wd. Working on getting this to the dealer but seems to be a fairly common issue with these trucks. Multiple individuals complaining of the same issues.

The dashboard instrument cluster of my 2019 RAM 1500 Gen 5, Longhorn model, is completely inoperable (went blank). This poses a safety issue to the driver as it provides important safety readings like velocity, fuel levels, RPMs, engine temperature, and distance traveled, etc. Roadways have a designated maximum speed. Meeting the speed limit is difficult if you can't read your speedometer. You can receive a citation for driving too fast, or worst, you risk getting into an accident. Not being able to read your engine temperature is vital to the life of your engine, it may pose a dangerous situation, as your engine can overheat. When I contacted the dealer, they advised that it is a common issue and that the Manufacturer is aware. The dealer advised that they couldn't duplicate the problem, when I took my truck to the dealer, as my cluster was working at the time. The instrument cluster turns on and off intermittently. The map light of the truck also stopped working. I disconnected the overhead light assembly, disconnected and connected the modules and they seem to work for now.
