The vgt actuator failed the truck only has 127000 miles on it ram extended the warranty for 2015 trucks but not 2016. The part to replace it from ram has almost doubled in a years time. It is now $2170. For this part whose internal computer components have failed. The files uploaded was just for the part. I can upload the repair cost when done. I am just trying to get everyone to see how corrupt these companies are becoming. They could have saved themselves some problems if they would just paid the $3000 to fix it this is a rough estimate.

Towing my trailer with my 2016 Ram 2500, at 48,000 miles I experienced complete turbo failure in heavy traffic at highway speeds. Power was reduced to minimums causing hazardous conditions. The "check engine" light illuminated. I maintained control and eventually had the codes scanned at both a local auto parts store and Larry Miller Dodge/Ram in Sandy, Utah. The codes identified were for the turbo actuator/turbo. Larry Miller said they could replace the actuator, but I'd be back in three weeks for the turbo replacement as well. They were three weeks out for labor. I contacted a local diesel repair shop who purchased the turbo and actuator from Larry Miller Dodge Ram and had it installed in a day. Subsequent to these repairs ($5,400.00) I have learned that MOPAR issued Warranty Bulletin D-22-06, dated March 16, 2022, for the same make and model as mine, only for the year 2015. My truck was built in 2015 and the parts and computer codes for failure are identical. This published warranty bulletin issued relief of a new extended warranty of 15 years /150,000 miles for the installed turbo actuator/turbo. Since mine failed at 48,000 miles, this could be a continuation of the aforementioned issue with the stated 2015 year failures. I was lucky I didn't create a traffic accident when this turbo system failed since it was sudden and violent when the loss of power occurred without warning. I'm asking you to probe or look at the facts that the issue with these Garrett turbos are still outstanding whether Doge/Ram/Fiat/Mopar wants to include them in their campaign. The danger is real. The costs to retired people, such as myself, is consequential and devastating. It is unfair there is no way of sending queries to the manufacturers to alert them of this condition. The only way to communicate is to talk to a person in India and the communication barrier is tremendously difficult as is the chance of getting any return on the days and weeks of attempts for resolution.

The service engine lamp came on. When the mechanic investigated, it was determined that the problem is identical to the Warranty Bulletin titled Cummins 6.7L Turbocharger Actuator - X99 Warranty Extension that pertains to the 2015 RAM 2500 pickup. My vehicle is a 2016 and there is no warranty extension, even though it is an identical problem. The vehicle was not drivable as is and I had to replace the Turbocharger Actuator. I am assuming that this is a known problem to Cummins and to RAM. There should be a Warranty Bulletin for the 2016 also.

It is known that the 2016 Ram crew cab 4x4 has exhaust leak problems. The bolts on the exhaust manifold will break and exhaust will escape the manifold causing extra heat to flow into the engine bay, and fumes to enter the cabin of the vehicle. carbon monoxide is colorless and orderless and causes headaches, nausea, dizziness, and even death if inhaled. The exhaust manifold leaks must be fixed.

We were driving our 2016 Ram in July 20, 2023 to Yakima, WA which is 200 miles away from our home. About 50 miles north of town, our check engine light came on and our power was reduced to a minimal speed. We cautiously drove to the next rest area and turned the engine off. We waited about 30 minutes, restarted the engine and continued to Yakima. We had the code checked and turned off at an Oreily's parts store. We drove it to an Independant diesel service center since the Ram dealership's schedule was 2 months out to look at it. After several hours and troubleshooting, the diesel technician determined that the Cumins Actuator and Turbo were failing. Each time they cleared the code and drove the truck, they could recreate the problem. They told us that it was the same problem that the 2015 Cumins Turbos & actuators were having. They said there is a chance that our truck was manufactured with the same parts as a 2015 Cumins. They were able to repair our truck and said that we should notify the NHTSA, Mopar and our local Ram dealer of the problem. Mopar told me there is no recall for this issue, so they cannot help. The local Ram dealer told me that since they did not do the repair, they cannot report the issue. Please help us as this was an expensive repair, not including the cost of being standed out of town for days. Our Ram only has 39,000 miles and is like new, always garaged and drove for pleasure. How can we get this investigated or reimbursed?

6.7L Cummins diesel Known Grid heater bolt broke and could leave people stranded as it causes catastrophic engine failure and or damage leading up to $20 to $30K in engine repairs. Ram knows about this issue and is doing nothing about it. Mine broke and I caught it just before it destroyed my engine. the fix was a $1k kit. This bolt corrodes and and drops down into the intake in which destroys the #6 cylinder, piston, wall and valves. Ram is doing nothing to fix the problem and leaving people stranded who haul trailers and with the big repair bills.

This message is in regards to Static NHTSA Bulletin 09-005-22 / D- 22- 06 Dated March 16, 2022. The above listed warranty extension extends Ram 2500 Cummins Turbo Diesel Model year 2015 to 150,000 miles or 15 years if code U010C is indicated on MIL. My truck meets all above criteria but is a model year 2016. However, there is no changes in mechanicals between the 2015 and 2016 model year. My truck, at 114,000 miles just indicated this issue and the estimated cost of repairs is over 2,000 dollars. Considering that this has already been a widespread notable issue with this truck and engine, my hopes is to include 2016 model years in this extension. Thank you.

I was driving my truck on the freeway pulling a loaded stock trailer. The truck suddenly down shifted into fourth gear and the engine RPM’s maxed out! I almost crashed the truck because the momentum of the trailer pushed the truck sideways on the freeway. I had to avoid traffic and get to the shoulder. Truck would not shift out of fourth gear and truck shifted into 4WD low also on its own. Had truck towed to dealers ship and was told a shift solenoid went out. Because of that they now have to change the torque converter and replace the transmission from the damaged it caused. It is unknown if it damaged any of the engine components at this time or any other parts of the drivetrain. Now I’m stuck paying for a transmission because Dodge didn’t put a safety backup into their system to prevent this in case of a failure. I see that I am not the first person it’s happened to by reading the power train comments for this year truck.

Engine Fan / Radiator Shroud. During hot weather and engine temperature, the engine fan engaged. Due to the high ambient, I believe the radiator shroud was hot and the material was soft, it became deformed under the vacuum created by the fan cause it to interfere with the engine fans path of rotation. The interference caused the fan and shroud to shred each other sending shrapnel in all directions, including into the back side of the radiator, engine compartment. Plastic debris was found on top of the valve cover, battery, radiator, exhaust manifold. This problem has been reported by numerus online forms. This failure was inspected by the dealer and I was informed it was not under warranty, but drivable and safe. Their recommendation however was to replace the fan, shroud and radiator. However, they have seen cases with far worse damage causing catastrophic failure of the radiator leaving the vehicle stranded

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2016 Ram 2500 Mega Cab verdict →
