Owners have filed 91 complaints
about the 2021 RAM 3500 with NHTSA between 2021 and 2026.
The largest single group is the electrical system.
Across this model's run it ranks 11 of 15 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 20
Against the median year of the RAM 3500. 50 means typical for this
model; 100 means roughly double.
Severity — 28
5.5% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 97
57% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
Odometer readings owners gave when they filed. About half of all
complaints include one.

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2021 RAM 3500
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

High pressure fuel pump failure
The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a compreh...
Recalls on the 2021 RAM 3500
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous

Recall 20256138 units in Canada
Airbag
Issue: On a small number of vehicles, the steering column control module may not have been manufactured properly. As a result, the driver-front airbag may not inflate in a crash. Note: This problem would cause the airbag warning light to turn on. Safety Risk: An airbag that is turned off could increase the risk of injury in a crash. Corrective Actions: FCA Canada will notify owners in writing and advise you to take your vehicle to a dealership to replace the steering column control module.
Recall 2024548314,717 units in Canada
Label
Issue: On certain vehicles, the tire and loading information label does not list that there is no spare tire in both official languages. The label reads as "NONE" when it should read as "NONE / AUCUN". Canadian regulations require the information to be listed on the label in both English and French.

Recall 202133630,899 units in Canada
Wheels
Issue: On certain pickup and chassis-cab trucks, the owner's manual and service manual list the wrong torque specification for the wheel nuts. As a result, some trucks may have had the lug nuts over-tightened during servicing. This can damage the wheel studs and, over time, they could break. If this happens, a wheel could separate from the truck. Note: This recall only affects trucks equipped with dual rear wheels and flanged lug nuts. Safety Risk: A wheel separation could cause a loss of control and increase the risk of a crash. A wheel that separates could also hit another person or vehicle. Corrective Action: FCA Canada will contact owners by mail and instruct you to take your truck to a dealer to inspect and replace the wheel studs, as necessary. They will also provide an update for the torque specification listed in the owner's manual.

ELECTRICAL SYSTEM
Our vehicle was involved in a total loss fire from the engine compartment while driving. We were driving the unit and noticed smoke, when we were merging to pull of the road flames started coming up and we immediately exited the vehicle and had to run, because it started popping. We were lucky to escape unharmed physically, but the situation could have been much worse. There were no indications or lights warning of engine failure or fire. This occurred on September 2, 2021. At this point in time there were no recalls on the vehicle. When we contacted Stellantis to report the incident, they concluded their investigation they denied responsibility. A few months after the fact we received notice of the recall. To date we have not been reimbursed for the loss of the vehicle, our personal belongings in the vehicle, and the loss of income from no longer having the vehicle. Our insurance company, Stellantis, etc all inspected the unit related to the claim and confirmed the fire began in the engine compartment.

The transmission’s light came on saying that it was heated. I parked as soon as possible and that’s when the flames were coming out of the hood. I did burned my hands trying to put out the fire with 3 fire extinguishers. I did not want my truck to burn. Now, the dealer is trying to say that they can’t get a conclusion of what started the fire. The truck smells like burned transmission fluid. I sent pictures of the truck to the dealer. There is a recall in February 2020 with the same problem that I had with my 2021 Ram. Prior to this incident, the truck did not have any warnings or lights on.

While driving my truck I noticed my mpg gauge was showing 0 mpg. Then I realized my "miles to go" gauge was reading "low" even though I had plenty of fuel in the tank and my fuel gauge was showing 3/4 full. Even though I use my truck as a commercial vehicle, and drive coast to coast, I was luckily only a couple hours from home, so I kept driving to try to make it home. I did make it home, but during that time, my "check engine light came on along with my "low fuel warning" light. I also realized during that time that my odometer had stopped working. It wasn't showing any numbers at all. When I got home, I checked online to see if anyone else had heard of this problem, or how to fix it. That's when I realized just how common this problem is. Even though my truck is used in the US and my mileage is calculated in miles, the odometer is programmed to stop working at 1,000,000 kilometers, which is 621,369 miles. Who would know or expect this to happen? I called several independent garages, all of which refused to attempt to fix an odometer problem because of the legal implications. I then called several Ram dealers who all told me they had never heard of this and would have to call FCA for advice on how to fix it. After two days of waiting, my local dealer called me back and said they could give me an appt a week later to diagnose the problem with my truck. They said FCA knows about the problem, but to fix it, it has to have a new gauge cluster installed. Nobody I talked to was able to tell me if the truck was safe to drive or why Ram wasn't warning owners of this problem when their trucks reached such an odd number of miles. When they replace the odometer, it will start over again at 0 miles and a sticker in the door jamb stating that the odometer was replaced at 621,369 miles, as if anyone would think to look in the door jamb for this sticker. The reason so few other drivers are going through this problem is because they are buying an OBD reader and resetting it.

POWER TRAIN
Vehicle died in a busy intersection coming off the freeway. Light flashed that indicated it was an issue with the electronic throttle control. The safety of myself and others was put at risk due to the posted speed of the road and multiple lanes from 4 directions. I had to remain in my vehicle to make sure I was not hit by another vehicle and due to the vehicle issue, I was impeding traffic. Lithia Dodge of Grants Pass, OR stated they could not make an appt for the vehicle to get looked at for 2 weeks out, scheduled 8/22/25. Dealership seems to think this is not an issue with safety and this issue can occur while the vehicle is in motion which is a huge safety issue. No warning lights flashed before the first one indicating the vehicle would shut down/lose all power.
