Mileage Failure Analysis
⚙️Engineering Insight
The peak failure range of 0-20k miles is alarming for current owners as it suggests that many problems manifest early in ownership—often before the first major service interval. This early onset of issues means that prospective buyers should be especially vigilant about warranty and service history when evaluating available units on the market.

STEERING,POWER TRAIN
I am reporting a serious safety issue with my 2021 Ram 2500 (VIN: [XXX] ). The truck has experienced three separate transmission failures within a few months. Each time the transmission was replaced, the vehicle failed again shortly afterward. At one point, the dealership returned the truck to me without transmission fluid, causing additional internal damage and creating an extreme safety risk. I have also had steering issues since the truck was new, which continue today despite multiple service attempts. Shortly after purchase, the truck developed severe mold and water intrusion after the roof stop lamp was removed or stolen while the vehicle was at the dealership for service. This caused water to leak into the interior and contaminate the carpet. The dealership replaced the carpet but the issues continued. The repeated transmission failures, steering defects, and water intrusion have made this truck unsafe to drive. The vehicle has lost significant value, and the dealership and manufacturer have been unable to correct the defects after numerous attempts. I am requesting an NHTSA investigation into these issues, including: •Repeated transmission failures •Ongoing steering defects •Improper repair practices •Water intrusion and mold exposure •Dealer negligence These failures represent a serious safety hazard to both myself and others on the road.

My vehicle was repaired for a known recall related to the tailgate unlatching issue. NHTSA ID Number: 22V904000 This repair was completed, and then my tailgate continued to open unexpectedly. I have taken it back to the dealership after damage was caused to my tailgate when it fell while I was driving. They have denied my claim and continue to advise that it was repaired when, in fact, I have still been experiencing issues with it. I would like to have my tailgate damage repaired and realgind properly.

SERVICE BRAKES
I have a seized brake caliper that is a direct result of a faulty brake hose. The brakes were looked at by a brake specialist business and I was told the brake hoses had to be replaced as well as the calipers, rotors and pads on the front. I took it to the Lake City, Florida dealer looking for a recall after reading online that some 2021 Ram 2500 trucks had brake hose recalls. They told me there was no recall on my particular truck for brake issues. However, when they quoted me there price and reason they needed to repair is that it had a seized brake caliper and all components are now no good. They also told me the brake hoses need to be replaced due to the passenger side brake hose having collapsed internally but they want me to pay $3500 to repair. This issue is a direct result of a faulty brake hose that they said collapsed. There are other trucks that have recalls for the same failure. Why is mine not covered under a recall with the safety issue that has developed? I need these parts covered as well as all the parts that have to be replaced due to the faulty hose. Please let me know what to do.
