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.

NHTSA complaint #11744944 — an unverified report by a vehicle owner.
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, were previously replaced by an authorized dealer. Following those repairs, the same warning light and fault code returned. The vehicle was subsequently inspected by another authorized dealer, which was unable to identify a definitive cause of the recurring condition. The check engine light was cleared, but it returned less than a week later with the same symptoms. The failure creates a safety concern because the vehicle may enter reduced-power or limp-home operating modes without warning, potentially limiting acceleration and the ability to maintain traffic speed. This is especially concerning when merging onto highways, crossing intersections, towing loads, or operating in heavy traffic. The recurring nature of the failure has reduced confidence in the reliability and safe operation of the vehicle. The condition has been reproduced multiple times and has been documented by authorized service facilities. Warning lamps and fault codes have repeatedly reappeared following repairs. The vehicle and emissions system components remain available for inspection upon request.

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.

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
