I purchased a dodge 3500 truck on October 16th 2024. My truck as of today has 4900 miles on it. It is a one ton dually. I noticed this week two of the rear outside tires have cracks and defective tread. I took it to a tire shop and they confirmed these tires are bad. I tow a 40 foot fifth wheel trailer. If I had had a blowout it could of been a huge problem for myself and those on the road around me. I spoke to the dealership I bought the truck from and they informed me they would have to see the tires and file a report with the manufacture of the tires. I had to buy all 6 new tires because I didn't want to chance a blow out with my trailer on the truck. I googled Nexen tires LT235/80R17 which are my tires. It says these are not rated for a 1 ton dually truck. When used on a dually it says its not the best choice for a 1 ton especially when towing heavy loads. The reason I bought this truck was for the purpose of towing my RV. I made that clear to the sales man at the dealership when...

Excessive Diesel Exhaust Regeneration. Vehicle in in regeneration about 72% of the time. Check engine light comes on about every 2 weeks with code P2459. The P2459 code indicates an issue with the diesel particulate filter (DPF) regeneration frequency in diesel vehicles. This code is triggered when the powertrain control module (PCM) detects that the DPF regeneration process has not occurred as expected. Have to take to dealership for a manual regeneration and to clear the code. Dealership says this is a known issue for Ram Diesel engines from 2018-2024. Dealership says Ram has yet to address the issue even though its been 7 years since the issue started in the 2018 model year. Been dealing with this for a year now.

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.

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.
