Recall Z46 for the High Pressure Fuel Rail. Truck has been down for a month and was told today my truck is still not fixed and they have no clue when the parts will be coming in for the to get my truck done.

- Broomfield, CO, USA

Engine failed at 142,000 miles. No prior indications or warning lights. Cam roller failed on cylinder #7 intake causing rod to throw through head cover, and valve to drop into cylinder #7 piston which damaged piston and disable engine. I have been advised that this was caused by the Variable Displacement mode the engine goes into when not under load, for better fuel economy. I have also been advised that this issue is not uncommon for these 5.7 Hemi engines which are advertised to last 200,000 to 300,000 miles. I had to replace engine and loss of use for 4 weeks. Not happy with Chrysler/Ram/Stellantis. I feel mislead/cheated.

Had the High flow fuel pump Changed and less than 400 miles had a catastrophic failure. Had to pay for a tow was told nothing is under warranty, even though it was caused all by a faulty fuel pump and caused other issues and was told by Stalantis that they do not cover calamity damage had to pay for PCM and injectors. My truck is still not fixed. My engine light is still on, brought it to three dealerships and nobody can figure it out. Also the deaf system is not functioning properly and had it replaced a 20,000 and at 70,000.

The engine seized up at 52,517 miles on February 28, 2025. It was making loud noises on the freeway and was losing significant power. We exited the freeway trying to get to a safe location and the engine froze. I had the engine replaced and the check engine light came on after 40 miles!

While being driven, the ecodiesel engine had a faulty ball bearing that malfunctioned inside the engine. This ball bearing then shot through the middle of the engine and out the bottom of the engine. The service technician at our local dealership inspected the engine and compared this to a "bullet under too much pressure due to a fault within the engine." He then said we "were lucky the ball bearing hadn't shot upwards through the floorboards." Not only could we have been at risk, other passing vehicles could have been shot with the ball bearing; this event could have led to wrecks and possible fatalities. The engine was completely destroyed by this defective ball bearing and cannot be rebuilt. No lights or messages appeared after the ball bearing shot through, even though the oil began draining instantly. The truck was pulled over and turned off before all the oil drained to prevent damage to the engine, which was already destroyed without us knowing.

Electric Power steering failure

- Westbury , NY, USA

Traveling on highway, heard noise coming from the engine. I was close to an off ramp and got off the highway. In the process of getting on the off ramp alarms went off. Turned on the flashers, came to a stop partially on the shoulder. Turned off the vehicle, turned it back on and it started right up. Turned to head into town to get some place safe to check the issue and all the alarms went off again. Put the car into neutral and coasted down the road to a local restaurant parking lot. Once safely parked, I opened the hood and my engine was on fire. I ran to the window of the restaurant to get a fire extinguisher and was able to put out the fire quickly. I contacted my insurance carrier and went through the process of repairing the truck. One body shop got it back up and running. Another shop fixed the cosmetic issues. However insurance would only fix the damage from the fire, not the cause of the fire. The truck has been throwing a code stating the EGR Cooler is not functioning properly. Stellantis sent out an independent investigator, however he wasn't allowed to look at the pictures that the body shop took after the incident. Since the truck was put back together and the cosmetic damage was repaired, he couldn't tell the cause of the fire. This EGR Cooler was supposed to be replaced during the recall (NHTSA Campaign # 19V757000), however I don't believe it was. Currently mine is cracked and supposedly the parts are on backorder. So there may need to be a recall to the recall.

We may have started a claim already reference number 1592940, this is the first I've been able to write out the details. On [XXX] we were driving through South Dakota on the freeway; which was cold but dry and clear with no hazards and within a mile everything happened or about 45-60 seconds First, it was like the gas wasn't getting through because RPMS went from normal to almost 5000. From there, my husband started losing driving power, so he started trying to pull over. Within seconds it seemed to lose engine power as were were pulling over to the shoulder. As we were pulling over the truck gave "loss oil pressure" and then died luckily as we just made it to the shoulder. If my husband had hesitated longer we would have been stalled on the freeway not able to start the truck again. The truck was towed to a local Ford dealership. The Mechanic said it may be a Ram recall but dropped it there and did not continue researching. We called the nearby Ram dealership where the mechanic said over the phone with out actually seeing the truck that is was not a recall. No one else has yet inspected the truck. I first need to know where I'm allowed to go to find an unbiased diagnoses and fair assessment. This was and is the only issue we have ever had with this truck. Maintenance was scheduled regularly, it was well taken care of and only had 110,000 miles on it. We have already had to pay for the towing to the dealership and also the towing from the dealership in South Dakota to home in Washington State to try and get this figured out.

my vehicle started knocking loudly, the all of a sudden I lost power on a 4 lane highway causing other vehicles to swerve around me. this could have been a accident if the road conditions were icy such as they are in Alberta. I had the vehicle towed to the dealership, the connecting Rods were in the bottom of the oil pan. since this incident I have learned of 2 other Eco diesels that had the same thing happen to them. These people are my friends and close aquaintances. So there must be more if I know 3 Eco diesels personally on my town.

- Condor, AL, USA

Engine started knocking at 65mph. Slowed to find a safe place to pull out of traffic lane. Before pulling over engine stopped but was able to get completely off the road. My safety was not directly at risk but had to wait at the side of the road for 4 hours waiting for tow. The dealer stated they have no idea what failed. The engine has not been inspected. The dealer told me I would have to pay to have it torn apart to find out what failed. There were no warnings except the engine knock. Oil pressure was normal, was not overheating and no check engine light. My safety could have been at risk had I been trying to pull out into traffic. Dealer has been doing all of the scheduled oil changes and inspections. I thought this may have something to do with recall 66A/NHTSA 23V-411. Dealer stated that could not be the reason as that recall fix is a software update?

I was driving this [XXX] ecodiesel truck and it threw a rod on a sketchy windy road on a mountain pass. I was told 65 mile tow one way, 90 the other; I chose the former (Liberty Mutual said they-??d reimburse $20 of my over $250 tow) thanks again! Not.)). Brought it to Ram in Show Low Arizona, Eric McGraw the service manager was terrific and communicated with me as much as he could. Unfortunately, they said the engine was out of power train warranty (I was at 99,840 miles at time of engine failure), -??by time not miles.-?? I had to call FCA directly and get a [XXX] case manager, Josh who was also stellar in my opinion. 9 weeks; 9 weeks without my truck. That-??s 7 total payments for it to what" Sit unfixed while FCA struggled with their top leadership? I bought this [XXX] ecodiesel engine because it was a diesel and diesels are notorious for having higher mileage capability; AND THEN to have everyone at Ram to FCA point fingers, shrug shoulders, and keep me waiting at my own expense; was simply intolerable to me. Luckily, FCA told me Ram would cover %65 of the repair (which is generous, but a slap in the face when I bought a supposed long life diesel from one of the top diesel companies in this country, and then to not cover the whole thing? BEFORE 100k miles"! So I paid $7000 out of pocket for this new engine. There was a lawsuit earlier which details how FCA settled in court over this same model -??only 2014-2016 models-?? supposedly.

I have a 2018 Ram, with the 5.7 hemi. I purchased it new in November 2017. I currently have just over 53,000 miles and began to hear a ticking sound on startup that lessened upon driving but never completely gone and could smell exhaust fumes in the passenger compartment. I took this to an independent service center and they reported that two or the rear bolts have broken off that secure the exhaust manifold and the gasket has been damaged. The mechanic states that this is quite common but not a recalled area from the manufacturer. The repair will cost close to $1,000 to repair. I do not understand that if this is a common and well known and documented problem and can be a huge safety risk due to the leaking of carbon monoxide into the passenger compartment, why hasn't this t been listed as a safety recall. I now understand that RAM is also discontinuing the production of the 5.7 hemi engine, are these type problems related?

Chrysler's 3.0L diesel engine have a high-pressure fuel pump with an open recall on them. A HPFP failure may introduce internally failed component debris into the fuel system and cause potential fuel starvation. In January of 2023, I attempted to remedy the situation with a RAM dealership in Aptos, California. The attached email chain shows that for 6 months, I was unable to receive parts for my 3.0L diesel engine. After a change in job opportunities, I ended up in Palmdale late November 2023, where I continued to pursue remediation at the RAM of the West Dealership in Lancaster. While I do not have a email thread on this, if you visit their store on 43226 10th St W, Lancaster, CA 93534, you find that they have an open ticket for this same recall that has been open since February 2024. I have had an open recall for 2 years now, which has prevented me from receiving a new registration sticker. My current RAM 1500, still has a sticker from 2022 despite me paying for all of my registration requirements. This has led to 3 tickets and a threat from law enforcement that they can take my truck. This has gone on long enough and I am demanded a solution.

The engine ticking constantly as well as an electrical issue with the radio, heating, ac unit, control panel in dash that has all of this in it constantly changes goes haywire, won't let you do anything to fix it. It flips from setting to setting as well as different screens and the cargo lights have a habit of staying on an draining the battery. The engine tick has been like that for i dont know how long but it seems all the ram 1500s have that same tick, the control panel started acting crazy about 2 months ago, the battery being drained this is the 2nd battery I bought in 2 yrs due to this issue. Not sure about the cargo light when that started. It's pretty crappy we use out hard earned money to purchase what we believe to be a great vehicle only to find its made so bad to have all these issues and no recalls on them. I'm sure I speak for all ram 1500 owners ram should take better care of their customers and the issues in which their products malfunction and fix the issue instead of leaving us high an dry, broke down along the road due to poor production. I'd like to see these issues fixed but not on my experience since the issue comes straight from the manufacturer.

My truck only has 89,000 miles on it and yet it sustained a $5,000 engine malfunction. The engine was overheating and it turns out, that the cylinder heads failed. I have found this to be common with the 3.6 L engine that I have. This problem also led to the water pump failing and cylinder heads to need repaired. Basically the entire engine except the engine block is being repaired. The engine overheated multiple times. The first time I had the thermostat replaced. The second time it was low on coolant and topped off. Bu the 3rd time, they were able to diagnose this hiding problem that they said is extremely common in ram trucks with the 3.6 liter engine.

The contact owns a 2018 Ram 1500. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer where it was diagnosed with a cracked particulate filter. The contact was advised that the particulate filter needed to be replaced. The vehicle was not repaired. The contact was informed that the part to complete the repair was on backorder. Additionally, the contact stated that the vehicle was consuming an excessive amount of coolant. The contact stated that the coolant level was over one gallon low within a two-week period. The vehicle was inspected for leaks, and it was confirmed that there were no leaks found. The vehicle was not diagnosed or repaired for the failure. The manufacturer was not made aware of the failure. The failure mileage was unknown.

My warranty work is being delayed until my warranty expires. The dealership said I could take my vehicle to another location, but that would mean leaving it there for several weeks just to get it inspected. This other dealership is about an hour away, and I live alone, so this isn't feasible. Am I really expected to accommodate the dealership just to get them to honor my warranty? The engine is ticking at idle, which I understand could indicate a failing engine. My truck also has a transmission issue-?"it slams into first gear when coming to a stop. The dealership looked at it early this summer but said I-??d be without a vehicle for a significant amount of time if I left it, and they didn-??t offer a loaner. This truck was originally purchased for $38,000 and came with a Certified Pre-Owned (CPO) warranty. Additionally, the headliner leaked within the first few months of ownership. The dealership (Champion Ram of Athens, Alabama) tried to get me to pay a third-party contractor for the repair, but it was clear they were trying to sell me unnecessary services, so I declined. I took it to a body shop friend, who found that the cab seams were leaking due to what seemed to be a manufacturing defect. This issue causes moisture to affect the 10-inch Uconnect system, which malfunctions when exposed to water. My warranty expires very soon, and it feels like they're just trying to avoid fixing these issues. The truck currently has around 93,000 miles on it. Please help in any way you can, because getting help from Ram has been like chasing a chipmunk!

Our truck only has 70,000 miles on it. My husband is a mechanic and has taken very good care of the truck. While traveling a few weeks ago the truck just started to miss and died. We lost all power. I am still under warranty thankfully. But I have read about all of the engines issues that are happening with this year and model. When is something going to be done about the engine failure" We could have died if we were on a busy highway. This is a very dangerous issue. I won-??t know what the issue is until I get it to the dealer. The issue is not coming up on the scanner that is used by the automotive shop that my husband works at. I really think that is an issue within itself also. Does someone have to die to be able to get this resolved" I am now thinking I will sale my vehicle when it gets fixed. I can-??t take any chances as we just bought a camping trailer and I can-??t imagine breaking down towing that. I-??m going to be the big loser in this situation as I will probably lose money selling it. Please step up and help us owners out with the known issues about this vehicle engine issues and issues the proper recall.
