Problem sheets

No single problem on the 2020 Ram 3500 has enough owner reports for a sheet of its own yet. The counts below still cover every complaint on file.

Is the 2020 Ram 3500 reliable?

The 2020 Ram 3500 has 116 owner complaints on file with NHTSA, below the median of 188 for 2020 pickups on this site. Of the 13 3500 model years since 2014, it has the 8th most complaints. Complaint counts rise with sales as well as faults, so read what owners report below before deciding.

At a glance

Next to the 2019 and 2021
At 17 complaints for each year on the road, the 2020 runs close to the 2019 (17) and above the 2021 (10).
Top problem
Two problems run close. Stalling has 23 complaints and fuel pump has 23, out of 116 in all. A quarter of the 16 owners who gave a mileage for stalling saw it by about 10,000 miles, and half by about 26,000.
Crash, fire and injury reports
12 of the 116 complaints (10%) report a crash, a fire or an injury. The typical vehicle on this site sits at 6%, so this one runs well above it. Counted separately (one report can carry more than one), 6 reports mention a crash, 7 mention a fire and 4 people were hurt.
Recalls behind the top problems
11 recalls are on file, but no problem here has enough reports to set against them.
When owners filed
Filings peaked in 2021 at 37 and have dropped every year since, to 6 in 2025. So far in 2026, 8 more have come in.

        How this compares

        2020 Ram 3500116
        Median 2020 model here (75 vehicles)219
        Median 2020 pickup here (13)188

        116 complaints is 1.9 times fewer than the median 2020 model on this site and 1.6 times fewer than the median 2020 pickup. Among the 9 3500 model years here it ranks 8th for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.

        Service bulletins for the 2020 Ram 3500

        Ram filed 762 bulletins and other notices with NHTSA that list the 2020 Ram 3500. 39 of them deal with a problem owners have reported on this car. Newest first.

        Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

        High pressure fuel pump failure. Open, led to recall 24V-957.

        NHTSA summary
        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 comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation

        NHTSA summary
        The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021 to investigate allegations of 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.On November 12, 2021, FCA filed vehicle recall 21V-880 and equipment recall 21E-094 on the subject population, identifying an `internally failed component? of the high pressure fuel pump equipped on the 6.7L Cummins Turbodiesel engine that introduced debris into the fuel system potentially causing fuel starvation and consequently an unexpected loss of motive power. Discussions with FCA identified the high pressure fuel pump equipped on these vehicles as the Bosch-supplied CP4. On December 16, 2021, Bosch filed recall 21E-101, stating the pump failure was a consequence of a manufacturer application-specific fuel system design.NHTSA subsequently identified recall 21V-586 involving loss of motive power due to failed CP4 fuel pumps on certain BMW vehicles.As a result of having received multiple recalls related to a common component, from two separate vehicle manufacturers, NHTSA?s focus shifted to determine if the related defect allegation was limited in scope to the recalled population. In early 2022, information request letters were sent to FCA and BMW to determine the root cause and consequentially identify the proper scope of potentially defective vehicles. After OD
