Does the 2020 Ram 2500 have fuel system problems?

Owner complaints say yes, as a model-year pattern. 69 of 162 relevant complaints filed with NHTSA about the 2020 Ram 2500 concern the engine, transmission or fuel system (44%), and the largest group is filed under fuel/propulsion system (40). For comparison, the 2019 scores 45% and the 2021 scores 53%. 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.

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.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.

Before you buy a 2020 Ram 2500

Questions people ask about the 2020 Ram 2500

Does the 2020 Ram 2500 have fuel system problems?

Owner complaints say yes, as a model-year pattern. 69 of 162 relevant complaints filed with NHTSA about the 2020 Ram 2500 concern the engine, transmission or fuel system (44%).

Are there engine or transmission recalls on the 2020 Ram 2500?

NHTSA lists 10 recall campaigns on the 2020 Ram 2500. Whether a specific car still has one open depends on its VIN.

Which Ram 2500 years are better?

Among the Ram 2500 years we track, the 2018 (4%), the 2017 (12%) and the 2011 (20%) have a lower engine and transmission complaint share than the 2020 (44%). Manufacturers fix things mid-generation, so the year before or after can be a different car.

Should I buy a 2020 Ram 2500?

That depends on the car in front of you, not just the model year. The 2020 Ram 2500 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. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
