Getting ready to replace the 6.7 Cummings Grid Heater before the loose bolt falls into the engine and grenades it. It's been a known issue since 2007. Why did Stellantis not generate a recall for this issue. If it fell off while I was driving It would expose me to a dangerous and potentially fatal condition. Are you investigating this issue.

On September 30, 2026, a Ram dealership completed the Emissions Recall 67A / VB6 software flash on my vehicle. Following the precise instructions listed in the official 67A Recall Owner Notification, I submitted a request for reimbursement for an out-of-pocket NOx sensor replacement that I paid for on March 4, 2022, prior to the recall's release. The documentation review team has twice issued a boilerplate denial stating: "The repairs were made prior to the effectivity of the extended warranty. We will not be able...

to reimburse those out-of-pocket repair expenses at this time." This denial reason is a catastrophic error in regulatory compliance: Confusion of Terms: The review team is mistakenly evaluating a Pre-Recall Reimbursement Claimunder standard, future Extended Warranty (XQ1) rules. Chronological Impossibility: By definition, a pre-recall repair must take place prior to the recall's execution. The 67A federal recall framework explicitly mandates that Stellantis reimburse owners for valid, out-of-pocket expenses incurred to fix the defect before the recall software flash was available. Regulatory Violation: Failing to honor valid prior-repair reimbursements directly violates the court-ordered emissions settlement guidelines established with the EPA and CARB. The frontline recall phone team stated they have no power to override the documentation department, and the documentation department is refusing to read the text of my appeal, simply copy-pasting the same invalid rejection code. I have met every legal prerequisite. The recall is completed and closed on my VIN, and my attached itemized invoice proves a professional NOx sensor replacement occurred.

Check engine light came on end of November 2025 and stayed on. Immediately I took the truck to two different independent mechanics. They both said it was a problem with the turbocharger but I never received a recall regarding this. They both said I could still drive it and that it would not leave me stranded. The last recall done was the 67A a year ago. There are currently no recalls for my particular vehicle through the NHTSA. The truck is currently having the very expensive turbocharger replaced by one of the independent mechanics. Why wasn't I alerted to this problem?

I was contacted to complete a recall on my truck, (67A), which I had performed by the local dealer. The recall notice also said "If you have already experienced this condition and previously paid for a repair, you may be eligible to receive a reimbursement." I spoke to an individual and followed the instructions to submit a claim. With no response, I tried to get a status; to confirm proper items were received electronically. I was told, they were received and the claim was denied? No reason or justification. I tried many times and was disconnected after asking to speak with a manager/supervisor.

I recently received a letter in the mail from FCA US LLC, about an emissions recall (Emissions Recall VB6 or 67A) on this 2014 ram. The recall covered many emissions components including the diesel exhaust fluid components. The recall letter also said that if I had replaced or repaired any of these components in the past, I may be eligible for a reimbursement. I had previously had to replace my Diesel Exhaust Fluid Pump back in 2021 and turned in the receipt for the work, but the claim has been denied. I just wanted to reach out to see if there was anything that done to help possibly get the reimbursement.

Upon starting the trucks engine, putting the transmission in gear (either Reverse or Drive), at idle engine speed (approx 700-800 rpm) or very low (near idle speed) the trucks engine starts to surge from idle then drops down to 500 rpms with a voltage drop (5V) too. It will do this a couple of times and then the trucks engine dies (engine stops) while in gear and no codes are shown on the CEL or saved in the vehicle control module. When I put the transmission in Park, the trucks engine restarts without a problem....

But when I go to Drive or Reverse gear it then will do it again. The truck sounds like the engine brake is being applied causing the engine to lug/bog down. The torque converter has been inspected and replaced. The fuel pump/lifter has been replaced. The batteries have been replaced. The fuel filters have been serviced; the crank case breather has been serviced. The emissions controls equipment (EGR valve) have been serviced/cleaned. Knowing that my trucks engine can cut out/die at anytime at low rpms, poses a safety hazard. Knowing that the truck can do this without a code being throw feels unsafe.

RAM has Turbocharger/actuator high failure rate. I have had 2 turbo failures in under 80,000 miles. When I lost the turbo I loose the exhaust brakes. This is very dangerous when towing and coming down a mountain road. This could lead to vehicle damage and loss of life. IN FACT: RAM on the 2015 model year only, issued a warranty extension for Turbo failures. This is serious safety concern due to NO exhaust brakes or no acceleration when needed to avoid a collision.

There is a ticking noise from the 6.4L Hemi that is in this truck. I took it into the dealer and I was told that it was normal. Recently The ticking got so loud that it sounds like the lifters or a rod that will shoot through the engine compartment and injure or kill someone.

on the 6.7L cummins diesel engines, as part of the cold start system, there is a bolt in the intake plenum that can come loose and eventually break off getting sucked into the #6 cylinder. when this happens, there will be catastrophic failure of the engine. This boltis barely visible looking from the top driver side of engine, a sure sign of this problem is the preheater wire connected to the intake plenum will seem loose and you can wiggle it.

If this problem is not noticed, eventual total failure of the diesel engine will happen, not maybe, but will potentially destroy the engine. numerous reports in the repair field have identified this problem and it needs to be addressed ASAP .... respectfully request that RAM/Cummins be contacted and at a minimum, a TSB be initiated so RAM owners can have this area inspected before total failure occurs

The heater in my pickup was not working correctly on the driver's side, so I took it into a shop to have the engine coolant flushed ($150). Within a few weeks, I had a check engine light appear and discovered the thermostat had failed ($350). I had this replaced. Still no heat. It was discovered that my heater core was plugged, could not be flushed, and the sediment from the coolant breaking down caused the failure in the thermostat, the heater core, and had plugged the EGR cooler ($3459 repair).

informed me they had had a number of these issues occur this winter alone on Ram trucks from this vintage and mentioned Chrysler had changed coolant beginning with Ram model year 2013, and that said coolant was routinely failing between 60-100K miles. Chrysler stated they would not stand behind the repairs since the original warranty had expired. I am the original owner of this pickup, keep it in a heated garage, very seldom tow, and I follow the maintenance schedules. Chrysler's own maintenance schedule states the coolant should be flushed at the earlier of 10 years or 150,000 miles. This truck is 8 years old with 93,000 miles on it. This failure was caused by a systemic defect

While towing a moderately loaded trailer, the cooling fan on the engine turned on. It appears the fan shroud got sucked into the fan causing pieces of the shroud to get thrown into the radiator, which in turn destroyed the radiator and leaked all the coolant onto the ground. A quick google search shows this seems to be an extremely common issue with these trucks. It seems that the design of the shroud is poor and should be remedied by the manufacturer. With such a sudden failure this left me stranded just over the top of a hill in the middle of the road with no safe place to pull over, creating a serious hazard.

I call chrysler customer center they tolled me that there is nothing they can do to help me. Can you please look into this thank you

In the last month when I have driven my truck for any amount of time, I have heard my turbo making an odd noise that doesn't sound like my turbo typically sounds like so I posted it to a few forums I belong to pertaining to my make and model of truck. Well the response I'm getting from them is that it is the vgt turbo actuator failing. And upon doing research for this part failing in other people's cummins 6.7 Engines, it's very common at or below 100k. If this part of the engine is this big of a fail point of the turbo it should be recalled and fixed so these turbos have a much longer life

Dodge called me back and said dropped valve seat but also cam/lifters need replaced. I dont see how dodge can just say it's on you to fix with this many vehicle owners all having the same problem. This is expensive fixes but not only that I have a truck with a loan payment that I cannot drive till it's fixed.
