Common problems with the 2020 Ram 3500

NHTSA's file holds 116 owner complaints on the 2020 Ram 3500. Owners named the fuel system most often: 33 complaints, and half of the 10 that list a mileage came after 5,600 miles. A complaint can name more than one component.

Mileage when owners reported a problem with the 2020 Ram 3500

The 44 mileages owners gave run from 1,834 to 300,000 miles. A quarter are at or under 5,900 miles, half at or under 25,700, three quarters at or under 61,589 and nine in ten at or under 140,867; 8 (18%) came after 100,000 miles, 2 (5%) after 150,000 and 2 (5%) after 200,000.

These mileages say when owners reported a problem, not when a 2020 Ram 3500 wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.

Most of these reports came early in the vehicle's life: 36 of the 44 came at or under 100,000 miles, so they say nothing about how many miles a 2020 Ram 3500 can cover.

Complaint mileage also follows a model year's age: the 2020 has had less time to cover miles than older years, so its figures will rise as it ages.

Is the 2020 Ram 3500 a good year?

Complaint counts cannot say whether the 2020 is a good or a bad Ram 3500: they rise with how many were sold and how long they have been on the road. They show how the 2020 compares with the other model years in NHTSA's file.

With 116 complaints, the 2020 ranks 8th of the 14 Ram 3500 model years from 2013 to 2026 with 10 or more complaints, counting from the most. The most: the 2018 (810). The fewest: the 2023 (17).

Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.

What these figures can and cannot tell you

  • Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
  • The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
  • The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
  • They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2020 Ram 3500 lasts.
  • A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2020 Ram 3500.
  • Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
  • 72 of the 116 complaints on the 2020 Ram 3500 give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
  • NHTSA name counted: 3500. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
  • Recall-file name matched: 3500.
