ENGINE
While operating my truck under normal driving conditions, the check engine warning light suddenly illuminated without warning. Due to concerns about potential vehicle reliability and safety, I immediately brought the vehicle to the dealership for diagnosis and inspection. After evaluating the vehicle, the dealership stated that diagnostic trouble codes were present and that additional analysis of the system would be required. The vehicle remained at the dealership for approximately one week before being returned to me. Upon release of the vehicle, the dealership advised that the issue was related to multiple erroneous codes and that a software update had been performed. However, the dealership did not provide a clear explanation as to why the codes were generated, what systems were affected, or whether the condition could reoccur. I was also not provided with a complete accounting of all diagnostic trouble codes identified during the inspection. I am concerned that the dealership failed to provide full transparency regarding the diagnosis and repairs performed on this vehicle. The repair order documentation was limited in detail and appeared to omit important information regarding the discovered fault codes and the full scope of work completed. Because modern vehicle systems rely heavily on electronic control modules and software for engine operation and safety-related functions, I am requesting that NHTSA document and review this issue for potential underlying electronic or software-related defects that may affect vehicle reliability and safety.

AIR BAGS
While operating my truck i have a air bag warning indicator come up on my cluster gage. With the light still one and engine running I immediately drove the vehicle to my local Ram dealer to seek assistance. I had spoken to a service advisor who checked my vehicle in for service. The service advisor did confirm the SRS light was on. After the tech did a diagnostic they found no stored service codes, the dealer cleared rhe codes, and said there was no issue and no repairs was performed. I find it very strange for the light to just randomly comon and there is no issues. I have reason to believe the dealership was not being transparent and did not provide the full scope of work performed on this truck.

SERVICE BRAKES
I am filing a safety complaint regarding a persistent soft brake pedal condition affecting my truck. Under normal driving conditions and especially during low-speed braking with no trailer or payload attached, the brake pedal feels excessively soft and requires additional pedal travel before adequate braking response occurs. The authorized dealer inspected the vehicle and replaced the brake pads and resurfaced the rotors; however, the soft brake pedal condition continues unchanged. After further evaluation, the dealer stated that their engineer determined the vehicle is operating within factory specifications and declined to pursue any additional diagnosis or repairs. I use this truck for towing an RV, and due to the abnormal brake feel and reduced confidence in braking performance, I do not feel safe towing with this vehicle. As a result, the truck remains parked at my residence because I believe continued operation may present a safety risk. I have driven other trucks of the exact same year and model that exhibited significantly firmer and more responsive brake pedal feel, which leads me to believe my vehicle is not operating normally despite the dealer’s claims. In addition, I have found numerous online reports from other owners describing similar soft brake pedal complaints, including reports of lemon law claims and unresolved brake concerns. I am requesting that NHTSA investigate this issue for potential brake system defects or inconsistent braking performance that could affect vehicle safety, particularly during towing or emergency braking situations.

POWER TRAIN, ELECTRICAL SYSTEM
This complaint notes two separate safety problems for the 2023 Ram 2500 Tradesman. 1) Transmission leak. "Heavy transmission leak" noted by dealer during normal service. Apparently so common that the seals are on back order. Was caught at 35453 miles so covered by warranty, but any issues related to the leak I am told will not be covered once they fix the leak. I have read this common leak has been known to cause pressure issues and fires. 2) Electrical issue related to key fob. Since the truck was brand new, an error message would light up the dash indicating "Key Fob not detected" This would happen when trying to start the truck and while driving. This has left me stranded several times from not starting the truck and having to wait an hour to get truck to recognize key fob. While driving, truck will go into limp mode until you park, turn off the truck, and restart with the same key fob. Have brought to the dealer many times. they state low battery. I pay for them to put in new battery. before I leave the dealership the problem still shows up. They have replaced the key fob twice now. The last time at 35453 miles. Dealer says Problem out of their control after 500 more miles at 36000 when warranty is up. If the truck stops working while driving because of key fob I am out of a truck? Both issues are safety concerns.

My vehicle has been in to 2 different dealerships for a warning light check airbag system. I have had it in to the repair shop approximate 5 times. It's fixed for a day or 2 then the warning comes back on. There is a safety recall for this and was performed a software update which didn't solve the issue. I do not feel safe for driving this vehicle.

ELECTRICAL SYSTEM, POWER TRAIN
I parked in a lot for about 30 minutes while taking a short hike. When I returned and started the truck the dash was black, no gauges, no PRND indication, nothing and the warning lights in the mirrors stayed illuminated continuously. We were in a National monument and decided to try and get back to the visitor center for someplace safe. When I placed the vehicle in what should have been reverse the vehicle rolled back but only because it was on a slope. When I shifted to where drive should be nothing happened. I tried several times as we were now in the traffic lane on a curve. I went completely back to park then cycled to drive and it worked. On the drive to the visitor center I noticed that the blinkers did not work either. Also, what I thought were manual gauges like the speedometer and fuel gauge did not work. When we got to the visitor center the vehicle would not shift into reverse from drive. I had to go back to park and then to reverse. I was able to get the vehicle working by disconnecting the negative battery cable for about 5 minutes. This just happened today and we are 1500 miles from home so the vehicle has not been inspected. If another car would have come around the corner while we were disabled they would have hit us as it is a one way loop so only one traffic lane that we were in.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The vehicle experienced repeated electrical and no-start issues believed to be related to the RF/electrical communication system. The truck has been returned to the dealership repeatedly for this issue and recently spent approximately two months at the dealership for diagnosis and repair. After finally being returned, the vehicle was completely dead the very next morning and would not start. The vehicle has also experienced dangerous electrical failures while being driven. During one incident at night, the headlights and interior electrical system became extremely dim and began flickering while an employee was operating the truck. Visibility was significantly reduced to the point the driver could barely see the roadway. During the same event, the brake pedal became abnormally hard to press intermittently, creating a serious safety concern while driving. The failure also occurred on our business lot where the truck was blocking multiple trailers needed for scheduled customer deliveries, creating operational disruption and safety concerns related to moving equipment and trailers around an inoperable heavy-duty truck. The dealership reportedly replaced or repaired an RF-related component/module during the repair process. However, the problem appears unresolved because the truck failed again immediately after being returned from service. Symptoms have included: * Complete battery drain/no-start condition * Flickering and dimming headlights/electrical systems * Intermittent hard brake pedal condition * Repeated electrical-related issues * Extended dealer downtime * Ongoing unresolved repair attempts The vehicle is available for inspection upon request. This truck is used daily for commercial/business operations. Reliability concerns are significant because unexpected electrical failure or no-start conditions can leave the vehicle stranded or create hazardous driving conditions. The issue has been reproduced after dealer repair attempts. Based on the symptoms and

BACK OVER PREVENTION: WARNINGS, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
I was in my yard backing my truck up and the camera froze in the location that I was in and the sensors did not beep. The distance that I was backing up was not very far. It wasn't until I backed into a post in the front of my house, that I realized the camera and sensors had temporarily failed.

VISIBILITY/WIPER
Description of the Issue: When full windshield defrost is selected—using either the infotainment system or physical HVAC controls—the system does not direct full airflow to the windshield. Instead, heated air is split between the windshield and floor vents, reducing airflow and heat at the windshield edges. As a result, ice forms and remains on the driver’s side windshield edge, beginning around the 11–12 o’clock steering wheel position and extending to the windshield edge. This occurs during cold conditions and restricts driver visibility, creating a safety hazard while driving. Safety Impact: The driver is unable to clear ice from the windshield edges, limiting visibility of adjacent lanes, pedestrians, and roadway conditions. When defrost is needed most, the system does not perform as required, preventing the driver from maintaining safe visibility. Inconsistent Operation: The HVAC/defrost system operates inconsistently under similar conditions. I have video evidence showing the system working correctly at times and failing at other times. In multiple cases, the only change was shutting the vehicle off and letting it sit. In one instance, the defrost later worked correctly the same day when ambient temperatures were warmer, suggesting a possible temperature-related or control issue. Videos documenting this behavior are available, including videos posted on YouTube. Additional HVAC Control Issue: The HVAC system will randomly set the temperature to 76°F and become unresponsive for approximately one minute. During this time, the driver cannot change any HVAC settings, creating distraction and preventing timely adjustment to address fogging or icing. This behavior is also documented on video. Repair Attempts: The vehicle has been taken to two RAM dealerships, and multiple parts have been replaced under warranty. The issue remains unresolved. A customer service case was also opened with RAM, but the HVAC and defrost issues have not been corrected.

POWER TRAIN
The 68RFE automatic transmission in this 2021 Ram 2500 6.7L Cummins fails to engage reverse when the transmission reaches operating temperature. When the gear selector is placed in reverse and the accelerator is applied, the engine revs but the truck does not move. The defect is intermittent and temperature-dependent, which means it cannot be predicted or avoided by the driver. The vehicle is used to tow an enclosed cargo trailer weighing approximately 7,000 pounds.The safety risk: inability to engage reverse on demand creates a hazard in any situation requiring reverse motion, including backing away from a stopped vehicle, reversing out of a fuel station, backing a loaded trailer at a campground or boat ramp, or executing an evasive reverse maneuver. With a trailer attached, loss of reverse function can leave the truck and trailer stranded in active traffic lanes or at intersections.The defect was first reported to a dealer in August 2023 with diagnostic trouble code P2701 stored (Friction Element B implausible pressure, internal transmission fault). The code was logged but not addressed at that visit. Over the following 32 months the same defect was reported to the same dealer four additional times. On the fourth visit the dealer replaced the complete transmission and torque converter under warranty and certified the repair complete after a documented 77 mile dealer test drive. The same defect returned approximately 4 customer miles after the truck was returned to me. The truck is currently at the dealer for the fifth repair attempt, with the dealer's own write-up confirming that the vehicle will not move while in reverse at operating temperature.The defect has been confirmed by the dealer service department through their own diagnostic process, has been documented across five repair orders, and has resulted in a complete factory transmission and torque converter replacement that failed to resolve the issue.Warning indicators: a P2701 diagnostic trouble code was s
