Heater grid fell of got into motor had to replace the motor and fuel lines, injectors, and turbo. Cost me over 30K cash. My wife withdrew from her retirement so we could afford to replace the motor. Then I had to take a job and move to be able to pay the truck off.
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.

Also approximately 2 years ago, I also had to replace the transmission. This truck only has 155,000 miles in it and has had 2 major break downs. WHY? This truck is unsafe.
My turbo actuator failed and was replaced in February of 2026. This is the same part, manufactured the same year as the recall: LOP#09440301 Both the manufacturer and NHTSA knew of this problem for years, but only fixed a small portion of the impacted vehicles. Please make me whole and refund my expenses for this known faulty actuator and repair work. Let me know if there is anything more you need from me.

On two separate occasions, once in 2025 and again in July 2026, while pulling a travel trailer an emissions control fault in the EGR system caused the Cummins turbo diesel engine in the truck to lose power. At this reduced power, highway speeds could not be maintained, and even small hills were difficult to climb. This is a significant safety problem, and the dealerships could not provide a timely repair due to lack of parts availability. The manufacturer of software in the engine control system does not allow the use of aftermarket parts. This is monopolistic and anti-competitive. An emissions control fault Code should not deprive me of the use of my vehicle.
The electronic throttle control light and check engine light are on. I took it to a mechanic and had the accelerator pedal replaced. The lights remained on and the truck remains in "limp mode" and will not go over 59mph. The mechanic stated that this is due to the unresolved recall problems with the traction control and anti lock braking system, and the HCU needing replaced. These components and labor are over 2-3 thousand dollars! I have called NHTSA and the manufacturer with questions and asked for a timeframe for a fix and have received nothing.
