New Car Assessment Program

The 2021RAM2500 carries 146 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 7 crashes, 12 fires, 3 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall Not Rated/5 rating, with Not Rated/5 front crash, Not Rated/5 side crash, and 3/5 rollover scores derived from standardized barrier and dynamic tests.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2021 2500 is electrical system with 34 filings, followed by engine (23) and power train (22). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 8 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle, the full NHTSA campaign numbers are listed below.

NHTSA currently has 2 investigation files overlapping the 2021 2500. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page, a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Front right wheel detached while driving on the highway - going about 45mph due to snow on roadway. We are glad no one was injured. All the lugs had come off the wheel. Now need wheel and rim replacement, and new hub assembly and lugs. It will be repaired at the dealer where we bought the vehicle new, Ed Tomko in Avon, OH. The service dept there has looked at it and gave the diagnosis. No warning indicators. Reporting because we saw a similar issue as recall for different lines of the same year Ram trucks. Wondering if the 2500 is also in that situation.

20260105SEAT BELTS

The rear right seat belt became stuck and would not release, trapping my [XXX] son. Although the buckle was unlatched, he was entangled in the seat belt, and the retraction system would not loosen. The vehicle was stationary at the time of the incident. Due to the inability to safely release the seat belt, emergency services were contacted. Police and fire department personnel responded to the scene and conducted an assessment. Based on their evaluation, they determined that the safest and most appropriate course of action was to cut the seat belt in order to free my son. This type of malfunction has never occurred previously with this vehicle. At no point before or during the incident were any warning lights, alerts, or messages displayed indicating a restraint system fault.

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 ma

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.

20250613SERVICE 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 pa

Steering wheel started to make a snap noise when being turn either to the left or right. Didn't happen every turn but would come and go and became more frequent. Took to dealer for diagnosis and they said it's the same noise the 1500s have when the clock spring failed or broke. He tried to see if we had that recall since it was on some 1500s and some 2500s but ours wasnt so we had to pay out of pocket.

The engine has had camshaft and lifter failure multiple times. The dealership has replaced the camshaft and lifters twice already , and now they have failed a 3rd time which has lead to metal in oil lubrication system. This has caused further damage to the engine crankshaft bearings, in my case the engine was still running with a tapping/knocking noise. However, this can result in engine locking up and causing vehicle to no longer operate. In the event of engine failure this heavy duty truck will have no power steering or power brakes, leading to a high likely hood of collision. This issue is widespread for all 2019+ RAM 2500 with the 6.7L Cummins engine. Ram has done nothing to address the faulty parts , and continue to replace with same flawed parts, and not correctly addressing the damage done to the engine after a lifter failure. Ram HD 2500,3500,4500,5500 are still being sold currently with these faulty parts.
