ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
***1*** The emissions system on this truck (2022 Ram 3500 with 34,435 miles) has been problematic since I acquired it 5 months ago. It continually attempts to regenerate and rid itself of ash/soot buildup. If it does not successfully regenerate, it will go into a state of reduced power, also known as limp mode. The truck is available for inspection and will be at Lithia CDJR in Corpus Christi tomorrow, 07 Jan 2026. ***2*** Today specifically, the truck flashed a message EXHAUST FILTER NEARING FULL SAFELY DRIVE AT CONSISTENT SPEED TO CLEAR. I got on the highway to achieve this and avoid lights and stop/go traffic. It typically takes around 25 minutes of consistent driving for it to clear. But today, shortly after I reached highway speeds, the truck entered limp mode, displaying EXHAUST FILTER FULL REDUCED POWER SEE DEALER. This was a very alarming incident that created a bottleneck on the highway and presumably for me to nearly be rear ended as it happened at 5:35pm. I was able to safely make it off of the highway, however this incident has put the lives of all motorists on the road around me today in danger. ***3*** The truck has been inspected numerous times by the dealership. The Diesel Particulate Filter was replaced on 01 October 2025 (this was the first time the truck went into limp mode on me). The frequent regenerations continued after the DPF replacement and a sensor was replaced on 29 October 2025. Regens continue at approximately 1 per week. ***4*** This is a known issue amongst the community of RAM truck owners. It's unfortunate that many do not report it because the safety issue could easily set off a chain reaction, especially if this heavy duty truck were to be towing a heavy load as it capable of doing.

ENGINE
The # 4 cam bearing seized to the camshaft. Upon further investigation the #4 main bearing was damaged from metal chips that were not removed during the manufacture of the engine. This damage from the manufacturing defect left the engine block damaged beyond repair. So a short block was ordered and installed.

ENGINE
Purchased the truck new with 25 miles on it from the dealer. Within the first 2000 miles, I had a message pop up that said "Service Exhaust System See Dealer". I took it in to the dealer, they said it showed a random emission related code had popped up but was not currently active, so their recommendation was to clear it and see if it came back. Within a day, the message was back and tripped a check engine light. I also noticed after the first 1000 miles, my fuel mileage dropping off significantly around the time the "Service Exhaust System" message first appeared. (I went from 18-19 mpg average, to 12-14 mpg average, driving the same commute to and from work, in the same conditions.) I have noticed unusually high temperatures in the exhaust at times, excessive fuel consumption, excessive DEF consumption, and am concerned about the potential for damage to the DPF or DEF system. I took the truck to my local dealer for diagnosis and repairs. They called me to say that the problem had been traced to a faulty Exhaust Gas Temperature (EGT) control module that was malfunctioning and would need replaced. They then explained that the part was "restricted" by Stellantis/Ram, and was not something they could just order. That they would have to create a "STAR" case with Stellantis and get the part authorized/sent directly from Stellantis. I was also told that they would not receive any updates or communication back on STAR cases and that the part would just show up whenever it shows up, and they would let me know. Was told to drive the truck until the part came in, as they did not have any loaner vehicles available. From some online groups I am in for this series of truck, I found a couple other people with the same problem, who reported that the restricted control module is on backorder from STAR/Stellantis until at least mid-January.

TIRES
I have had two tires separate in the past couple of months with less than 24000 miles and 5 years old. I filed a complaint with Nexen and they sent a partial payment for the first one but rejected the second claim that happened less than 500 miles of the first claim. They claim the tires are separated because of the low miles on the truck and it is not driven enough. Less than a year ago my brother had the same issue with the same tires and truck with similar mileage and was sent a check for 6 new tires. I have additional photos and photos of the other tire as well as emails with Nexen and XXX Sr. Quality Analyst © [XXX] [XXX] ® [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

AIR BAGS, SERVICE BRAKES
I was towing a 6,000 pound excavator on a 20’ tilt deck trailer and rounded a turn to see a line of traffic stopped waiting on a big truck to turn. I hit the brakes and the truck didn’t start to slow. I swerved to the shoulder and pressed breaks as hard as possible and went past several cars and t boned the big truck that was turning. The only brakes it felt like i had was the trailer brakes. Very severe accident that everyone walked away from but definitely was equipment failure involved.

ELECTRICAL SYSTEM, BACK OVER PREVENTION
The contact owns a 2024 Ram 3500. The contact stated that upon purchasing and driving the vehicle, the contact noticed an abnormal odor inside the cabin of the vehicle. The dealer was notified and informed the contact that it was a new vehicle odor. The contact stated that while driving at 65 MPH, the contact noticed clear smoke coming from the vents. Additionally, the contact stated that the rearview was inoperable. The vehicle was taken to the dealer, where it was diagnosed that the cab heater had experienced an internal short circuit, causing the wiring and grid heater to melt. The vehicle was repaired; however, the failure recurred while driving. The contact sustained extreme fatigue, sore throat, nausea, headaches, ringing ears, and vomiting. The contact had not received medical assistance but had taken a 3-day leave from work. The dealer was contacted via email and informed the contact that the heater assembly might not be the cause of the failure. The contact was concerned that the vehicle failure could cause a fire. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 20.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, ENGINE
While driving my truck I noticed my mpg gauge was showing 0 mpg. Then I realized my "miles to go" gauge was reading "low" even though I had plenty of fuel in the tank and my fuel gauge was showing 3/4 full. Even though I use my truck as a commercial vehicle, and drive coast to coast, I was luckily only a couple hours from home, so I kept driving to try to make it home. I did make it home, but during that time, my "check engine light came on along with my "low fuel warning" light. I also realized during that time that my odometer had stopped working. It wasn't showing any numbers at all. When I got home, I checked online to see if anyone else had heard of this problem, or how to fix it. That's when I realized just how common this problem is. Even though my truck is used in the US and my mileage is calculated in miles, the odometer is programmed to stop working at 1,000,000 kilometers, which is 621,369 miles. Who would know or expect this to happen? I called several independent garages, all of which refused to attempt to fix an odometer problem because of the legal implications. I then called several Ram dealers who all told me they had never heard of this and would have to call FCA for advice on how to fix it. After two days of waiting, my local dealer called me back and said they could give me an appt a week later to diagnose the problem with my truck. They said FCA knows about the problem, but to fix it, it has to have a new gauge cluster installed. Nobody I talked to was able to tell me if the truck was safe to drive or why Ram wasn't warning owners of this problem when their trucks reached such an odd number of miles. When they replace the odometer, it will start over again at 0 miles and a sticker in the door jamb stating that the odometer was replaced at 621,369 miles, as if anyone would think to look in the door jamb for this sticker. The reason so few other drivers are going through this problem is because they are buying an OBD reader and resetting it.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS
2025 ram 3500 dual rear wheel truck has intermittent anti lock brake failure . As well as traction control, forward collision warning/assist, lane departure, high beam headlights, and other safety systems. The dealership has tried to fix these issues 8 or more times, with no success. It is illegal for Ram and Stellantis to put customers back into vehicles with anti lock brake failures. In wet/slick/or hard braking situations, loss of anti lock brakes is dangerous to my family as well as other drivers on the roads. And that danger increases when towing a large trailer when the failure happens. The dealership and Stellantis/Ram know of these problems with 2025-26 dual rear wheel Ram pickups.

POWER TRAIN, FUEL/PROPULSION SYSTEM, ENGINE
My pm sensors or particulate matter system malfunction and failed which lead to emissions issues and created my vehicle to drive in limp mode. Limp mode basically slowed downs the vehicle is slow as 5 mph as soon as this light displays at any time while driving on the highway. This put my safety in danger and the public as I transport what dot considers a type hazardous material. The sudden loss of power in the middle of the road has made vehicles around me extremely vulnerable to fatal collisions. I took my vehicle to the dealership where they confirmed this malfunction and problem with my vehicle but no recall has been issued as of yet no warning lamps appeared prior to the failure.
