SERVICE BRAKES
The brakes do not apply until after the pedal reaches half of its travel distance and still not as good they should. Very soft pedal feeling and too long of pedal travel to apply brakes. Very unsafe! I have had it to the dealer 3 times for this condition since I had purchased it (New) on June 5, 2025. They bled the brakes and found a small omaunt of air in the system. This did not change the braking condition at all. They cannot seem to find the problem. Service advisor did tell me that recently another customer brought in his 2024 Ram heavy duty pickup with the same issue.

ENGINE
Failure of hydraulic lifters and camshaft in Cummins 6.7 liter diesel engine of 2021 RAM 3500. Engine exhibited significant ticking noise and the engine does not work properly, putting the safety of driver and passengers in vehicle at risk. Vehicle is not driveable. This issue has been confirmed by the RAM dealership in Livingston, Montana. The 2021 RAM 3500 truck has been sitting at the RAM dealership for the past seven weeks awaiting parts and a fix that RAM trucks is still trying to figure out. Apparently, this has become a common problem with the RAM Cummins 6.7 liter diesels from model years 2019 through current 2025 models, including 2021. The RAM dealership in Livingston, Montana has five separate RAM Cummins 6.7 liter diesel trucks with the same issue awaiting parts and a fix from RAM.

ENGINE
Recently I was informed about a possible engine failure involving a "Grid Heater Bolt". Upon my query, I learned the following: The RAM grid heater bolt failure can lead to serious engine damage. Here are some key points: 1. The grid heater nut can melt and fall off inside the intake plenum, often due to the grid heater relay sticking "on". Or fall off due to vibration. 2. A bolt in the 2007-2023 RAM 6.7L intake air heater can cause severe engine damage, and a warning code (P2609) may indicate this issue. 3. The grid heater bolt/nut can wear from heat or vibration, potentially dropping into the cylinder and destroying the engine. The risk related to this can be minor to catastrophic. Any potential engine failure during operation could cause damage, fire, injury or death. Upon researching this issue, I found the Internet full of warnings, but yet since 2007 to 2023 no factory solution or recall has been made. A recall has been made for simuliar issue. See attached. As a preventive measure, I am replacing mine with a aftermarket device. Something Ram or Cummins engine should have done since 2007. I have not been in a collision or a engine failure. But I am sure since 2007, someone has. There are two or three aftermarket repairs that the manufacturer should have resolved.

SERVICE BRAKES
As I was exiting the highway with a loaded trailer carrying approximately 10,000 pounds, the ABS and brake warning lights illuminated on the dash, along with a “No Trailer Brakes” notification. When I applied the brakes to slow down, there was little to no braking response. Fortunately, I was able to safely pull off the road. The truck has now been at the dealership for two weeks, and the technicians have yet to identify a solution.

POWER TRAIN
sometimes when I first start the truck and drive off, I find out that I have no throttle response at all. No smoke or abnormal noises, just a dead pedal. Then after I stop the truck and take off again it works perfectly normal. I've heard of others having this problem but haven't heard of a fix. I also can't duplicate the problem; it has only happened a couple times. I did check for any codes which I did not have any.

EXTERIOR LIGHTING
Every time I turn my left turn signal on my headlights high beams come on weather headlights are turned on or not even if I have my headlights on on low beam, it does not do it when I turn my right turn signal on. It does it whether I have my auto headlights on or off. I'm sure it's been happening longer than that that's just the first time I was informed by someone I was following on the highway

While test driving a 2017 RAM 3500 6.7L Cummins diesel at Cherry Hill Dodge Chrysler Jeep Ram in Cherry Hill, New Jersey, both the check engine light and the regen warning light came on simultaneously. I returned to the dealership, looked up the regen warning, then retrieved my BlueDriver OBD2 scanner from my own vehicle. I scanned the truck on-site and ran live data. The scan confirmed the diesel particulate filter (DPF) was 100% full, and the regeneration system was not functioning. Permanent fault code P242F was stored, and the exhaust backpressure reading was over 25 PSI at idle — indicating a severely blocked system. These faults were not disclosed by the dealership, and no inspection or documentation from a diesel technician was available. I later discovered the truck also has an open safety recall (Manufacturer Recall Number: C4B / NHTSA Recall Number: 24V-896) for a potential failure of the Brake Hydraulic Control Unit (HCU). This recall involves the loss of ABS, Electronic Stability Control, and Traction Control, and the recall status is listed as incomplete with no remedy available as of the test date. I offered to purchase the truck for $35,000 out-the-door on the condition that the emissions system was repaired and certified. The salesperson spoke with the manager, then returned and told me the vehicle was no longer for sale. I then overheard the manager say they planned to wholesale the vehicle, likely without disclosing these active safety and emissions system failures. I am filing this report to ensure the vehicle is flagged for unresolved safety and emissions violations before it is sold or auctioned in its current condition. I have full diagnostic scan data, photographs, and written communication from the visit available upon request.

TIRES
August 2024, arrived to Discount Tire, Lee Store in Prescott Valley, AZ. Showed salesperson my Ram 3500HD, also reflected on my account with them. Salesperson ordered 122Q instead of 122QE for 1 ton truck. This was intentional as 4 months later (December) brought in for excessive wear, manager on duty declined warranty and tried Toyo who required I go back to dealer placing me into procedural loopholes and denial of service from both. This week noticed drastically worse and demanded reopening of December claim. Same dealer manager on duty did nothing, reached out to Toyo again. At no point did anyone (Toyo, salesperson or Discount Tire Manager) admit the mistake as kept repeating premature disintegration of tread and safety issues. After continuous delays, knowing vehicle is 3500HD and these are not E-10 no viable actions taken to secure my safety. I researched further and found the wrong tires were installed on my vehicle. Tire company knew and withheld this vital piece of information and failed to take action when reported back in December and again in July. Tire on vehicle: Toyo Open Country CT - LT275/70R18 125/122Q. I have the back and forth emails for this month's and December. I've enclosed the one tire (purchased 4).

The transmission in my vehicle failed suddenly on May 31, 2025, entering “limp mode” and losing the ability to shift properly. The vehicle became immobile and was towed to the dealership. Initial diagnostics revealed difficulty shifting between 3rd and 4th gears. Service technicians attempted repair in June based on RAM TSB MC-10231775, which indicated snap ring failure in the Aisin transmission. Repairs prescribed in TSB were attempted but unsuccessful, as the vehicle still could not shift into 4th gear. Additional parts were ordered, and another repair was unsuccessfully attempted in late June. Ram has shipped a new transmission which we are waiting on the dealership to install.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I have not been involved in an accident yet. You can’t drive the truck because the warning goes every 2 minutes. The brake hydraulic control unit has failed and they will not fix the truck. I can’t pull my camper. I have at least 6 hours on the phone with Ram and they say there is nothing they can do. The dealer ship says they have the part that is on the truck now, but Ram will not allow them to install it. It’s not the new part. Mean while my truck is useless until they fix it. They have been aware of this issue since 2017 and they still do not have a replacement part. The right thing for them to do is put the they have on hand on it so I can a least drive the truck. The truck has 90k miles on it. The vin # [XXX] . My contact info is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We bought our 2024 3500 Dodge RAM in Florida in late March. Last weekend the truck started to feel like it was jerking while we were pulling our 5th wheel. On Monday we schedule an appointment in Brockton Massachusetts at a dealership. We were told there need to be a system update and that it was all set. On Wednesday we started our 3 hour drive to Maine when suddenly while we were on the highway the truck began to overheat and revving loud only going 35mph. We pulled over into a parking lot and called RAM roadside assistance. We were told to let the truck cool down and try again. After being in a parking lot with our 4 kids and 2 dogs in 100 degree weather for 6 hours we attempted to start the truck. However every time we put it in drive the truck shut off. At this time we had to get it towed for $300, today the local RAM autoshop is saying they looked at the truck and transmission is gone. They are also saying they will not be able to look at the truck for a month. We travel full-time in our RV and now are stranded with our RV and no way to pull it anywhere.
