The vehicle has experienced repeated failures related to the diesel emissions system despite multiple repair attempts. The primary symptom is an illuminated check engine light accompanied by diagnostic trouble code P2459 (Diesel Particulate Filter Regeneration Frequency). The vehicle frequently enters regeneration cycles and continues to exhibit the same symptoms after major emissions system repairs. The emissions system components, including the Diesel Particulate Filter (DPF) and related DEF system components,...

My truck was started in the morning and as it sat idle in the driveway I started attaching my trailer. By the time I got the trailer attached(20 seconds) there was smoke pouring out from under the hood. I immediately turned off the truck popped the hood and it was engulfed in flames. I was able to put out the fire with the garden hose. No check engine lights, no warning lights on dash, and I had just got it back from the dealership 2 days earlier and it passed a safety inspection before I picked it up. Im not sure what component failed but whatever did caused a fire

Vehicle: 2023 Ram 2500 Diesel (6.7L Cummins) - approx. 36,000 miles, under factory warranty Complaint Summary: Our 2023 Ram 2500 diesel is producing visible smoke from the engine bay and a persistent ticking/clicking noise from the engine.

I am reporting a recurring safety defect involving hydraulic lifter failure in Ram trucks equipped with the Cummins diesel engine (model years 2019-2024). This issue is widely acknowledged by Stellantis and multiple dealers. It typically begins with a knocking sound and has been documented in many cases to progress to complete engine failure. My vehicle has fewer than 20,000 miles. The lifters were already replaced once, which required the cab to be removed. Within less than 400 miles of that repair, the knocking...

My 2023, Ram 2500 truck with a Cummins 6.7L diesel engine has a known defect with the grid heater bolt. This bolt can loosen or break off, falling into the engine and causing catastophic engine failure. This creates a suddne loss of power, espcially dangerous when towing heavy loads at highway speeds. Numerous owners have reported this issue, yet no recall has been issued. I request investigation and action to protect driver safety.

Truck has had lifters replaced due to tick, sluggish performance and engine vibration. Truck was driven less then 500 miles and problem re-occurred. With research I have learned this is a widespread problem, and ram techs have reported complained there is no fix, and they are just reinstalling parts that will fail again. I feel the engine has had metal ran through it which in my opinion could cause this engine to seize up at. T tow a larch travel trailer with my family an and small pets in this vehicle.i live in...

Engine had a tick, dealer said it was lifters. Dealer replaced lifters after having the truck for three weeks. Noise is back 2022 ram 6.7 with 17000 miles. This issue could cause engine failure at any speed and I use this truck to pull a large travel trailer. I'm concerned the noise is back and putting metal shavings into the engine will cause catastrophic engine failure at some point.

This defect is tied to a known issue identified by Stellantis in Technical Service Bulletin #18-002-24, which acknowledges improper MAF sensor calibration or compatibility on vehicles like mine. The bulletin was verbally confirmed by the dealership as applying to my truck. This...

5th gen ram with the 6.7 Cummins diesel have a massive problem with lifters. Extremely common for trucks with under 10k miles needing the extensive repair done. I've read in some cases people whole motors breakdown due to this failure while on the highway pulling a load. My specific truck had to have all the lifters replaced at 76k miles. There needs to be a manufacture recall on these.
