Within 24 hours of buying the vehicle back in February, the truck has not run red Lightning bulbs, electronic throttle control system Lights all started coming on that system was replaced by a certified mechanic. The system then did it again, literally, 1 day later. Now I'm not certain about the new part, which has been discontinued. It's some sort of pigtail off of that. And again the wiring pigtail or whatever it is called. I am uncertain is defective in has been discontinued. I'm into the truck for over $10000, including the purchase price. It has not run 1 day since But after the incident, my mechanic did the car fax on it. The odometer had been rolled back over 100000 miles or replaced whatever the situation, the car facts did not match up with the actual truck information that was sold to me contacted the individual and sold me the truck. He has ghost meat, will not return. Calls will not give me back. The money will not even answer my calls. Any longer longer only through the national highway transportation safety association did I find out that this could be defective parts possibly covered by the manufacturer. So again , i'm not sure where I stand on this uncertain i have contacted several state and federal government agencies. That's how I ended up here, trying to go through the process of getting this taken care of but I got the Attorney General national highway, safety transportation board involved along with the state police, I guess here in Massachusetts have a division for this so. I'm filling out the form and doing what i'm supposed to trying to get myself reimbursed , or at least this truck fixed , because again pots have been discontinued and nobody including dodge dealerships , do not want to work on it the truck is currently sitting in a mechanic shop.All receipts of work done and affected parts is in the truck at mechanic so I have receipts for all of this
2016 Ram 1500 engine complaints
Page 2 of 13: complaints 11 to 40 of 354, newest first, as owners wrote them.
I own a 2016 Ram 1500 EcoDiesel, VIN [XXX] . The vehicle has been in and out of Rydell Jeep & Ram dealership over 3 times in the last few months for fuel pump issues. It has been at the dealership for over a month total (in and out). Each time I have had to pay for towing and rental cars. I have not been reimbursed for any rental or towing costs. On April 11, 2026, immediately after picking up the truck from the dealership (where it had just been serviced for a previous fuel pump issue), the vehicle suddenly lost all power while I was driving on the freeway and would not restart. It was towed back to Rydell. On April 23, 2026 at 9:30 AM, Bruce (service advisor) and Mike (mechanic) at Rydell verbally admitted to me that their original diagnosis was wrong. They had initially said a gear inside the engine that turns the CP4 fuel pump had come loose or failed. They now admit that diagnosis was incorrect, but they refuse to provide that admission in writing. They are now trying to charge me for the repair. I believe the actual root cause is that the CP4 high-pressure fuel pump seized internally. That seizure would have placed extreme resistance on the engine's drive gear for the pump, causing the gear or its retaining bolt to fail as a secondary consequence. The pump seizure is a known safety defect in these EcoDiesel vehicles. Because the dealership has admitted the original diagnosis was wrong, and because this failure happened immediately after fuel pump-related service, I am requesting that the federal safety agency investigate this as a safety defect. The sudden loss of power at highway speeds is extremely dangerous. I also request that any existing recall or investigation (such as the federal safety agency Campaign 22V406000 a INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The vehicle turned off on the freeway and qould lnt start right after it came out from the dealership for a fuel pump cp4 installation recall, they said they misdiagnosed the issue with the truck on 4/23/26 930am from Bruce service advisor and mike the mechanic at rydell with my fuel pump off the truck. They said the gear that turns the fuel pump may have come loose That gear that turns the fuel pump does not turn, they showrd me. Also im thinking that the fuel pump seized and caused this issue. Why would the inner gear not work after yhis situatio
During a routine oil change test drive, a code for Crankshaft Loss of Position appeared on my truck and as a result, the autoshop I took it to (a Kerry's Car Care) recommended that I do not drive it. This is an active Recall from the FCA from the federal safety agency (Safety Recall W68 / the federal safety agency 20V‑475 Loss of Crankshaft Position), but Dodge is insisting the recall was repaired (66A/the federal safety agency 23V‑411) but only an update to the software as issued, without replacing the actual faulty part, the tone wheel. This problem was discovered and inspected by the Kerry Car Care, but I anticipate that Dodge Chrysler will deny the repair, even though it is a safety recall issued by the FCA. There were no signs of failure prior to the test drive done at Kerry's.

The failure mileage was approximately 204,000.
On September 29, 2025, my vehicle overheated. Smoke was coming from the interior vents as well as from under the hood. I pulled over shortly after and had my vehicle towed to a repair shop. I got an estimate for radiator repair. That did not fix the issue, so more repair was needed related to a heating and evaporator core. I have attached the invoices for those repairs. I just wanted to note this for my records.
Recall for intake manifold for our ecodiesel 2016 Ram and you do not show a recall for our specific truck. Which, GM service has verified we need to replace the intake manifold. Hesitation, drag, engine light, etc...
The 3.0 eco diesel has a known defect involving the oil pickup tube clogging up with soot and diesel particles which then causes catastrophic damage to the engine and they blow up due to engine bearing failure which could lead to a safety issue while operating the vehicle on the roadways there are numerous videos online regarding this issue and it needs address and mopar needs to correct this and recall all the trucks and replace the engines and redesign the oil pickup tube to prevent the oil pickup tube from clogging up it’s unfair to the owners of the trucks and so many of the trucks are being scrapped due to the engine failure issues new engines cost $11-$18,000 to replace

My Ram 1500 will randomly loose power while driving then pick back up, I have had several issues with electrical including lights flickering or going our for a minute then back on while driving at night, steering wheel controls not working, key fob issues, it also shifts hard at times others its normal. I was told all recalls have been done but personally can not confirm, had it looked at by several mechanics and cant find anything that they say would cause these issues.
I own a 2016 Ram 1500 EcoDiesel (VIN: [XXX] ). This vehicle is covered under the EcoDiesel Approved Emissions Modification (AEM) Settlement extended warranty. Since the update in January 2025, the truck has suffered repeated EGR system failures and related warranty failures. The EcoDiesel lawsuit itself was based on EGR cooler defects that could leak coolant and cause fires. My truck has experienced the same failure pattern, with coolant leaks, overheating, and unsafe breakdowns. On [XXX], the vehicle shut off in the middle of the road while I was driving, creating a serious hazard. The cause was traced to a covered emissions component. This was not an isolated incident. The vehicle has been in dealerships for over 60 cumulative days since January 2025, mostly for repeated EGR codes and fuel system issues, but the root problem has never been properly repaired. On [XXX], the low-pressure fuel pump failed after it had already been replaced. The premature failure left me stranded and required a $500 tow. This failure also presented a risk of sudden power loss in traffic. Despite repeated visits to authorized dealers, repairs are incomplete or improperly billed, including installation of non-OEM parts that failed again. The repeated stalling, coolant leaks, overheating, and sudden no-start conditions show that this truck remains unsafe to operate on public roads. I am reporting this as a safety defect because the emissions system failures and improper repairs have caused the vehicle to shut off while driving and continue to present a risk of fire, engine damage, and sudden loss of power.

2016 RAM Ecodiesel in shop with crankshaft position sensor error. Vehicle available for inspection at Sarasota RAM. Vehicle shut down on highway. Restarted but only would operate in limp mode which enabled me to drive to dealer. Warning lights indicated crankshaft position sensor issue. I had W58 recall performed but not selected for W68 fix. I spoke to Phil (844‑378‑0573 Ext: 4060587) at RAM customer care, who stated "Our primary focus is your satisfaction" (customer care case #[XXX]). This problem is very evident by the many 1500 drivers complaints. Action to reimburse me for the repairs is required.
