Check a VINDoes the 2020 Ram 3500 have fuel system problems?
Owner complaints say yes, as a model-year pattern. 58 of 116 relevant complaints filed with NHTSA about the 2020 Ram 3500 concern the engine, transmission or fuel system (51%), and the largest group is filed under fuel/propulsion system (33). For comparison, the 2019 scores 42% and the 2021 scores 43%. On a test drive, check for hard starts, stalling, hesitation, a fuel smell or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
Complaints by component
The years either side
Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.
Cleaner alternatives
Same car, a better year
Other heavy-duty pickups with no elevated signal
The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

Recall campaigns on the 2020 Ram 3500 (11)
This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2020 Ram 3500
- Ask the seller whether the fuel system has ever been repaired or replaced, and whether the car has shown hard starts, stalling, hesitation, a fuel smell or a check-engine light.
- Drive it from a cold start and long enough to warm up. Many fuel system faults hide once the car is warm.
- Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the fuel system.
- 11 recall campaigns on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
- Ask for service records. A fuel system already replaced under warranty is a different car from one that was not.

That depends on the car in front of you, not just the model year. The 2020 Ram 3500 has an elevated fuel system complaint pattern, so treat it as a car that needs proof: service records showing fuel system work, a cold-start test drive, and an independent pre-purchase inspection focused on the fuel system.
