Is the 2020 Ram 2500 reliable?
The 2020 Ram 2500 has 162 owner complaints on file with NHTSA, close to the median of 188 for 2020 pickups on this site. Of the 13 2500 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 23 complaints for each year on the road, the 2020 runs close to the 2019 (24) and above the 2021 (18).
- Top problem
- No problem dominates. The largest, diesel fuel system, covers 30 of the 162 complaints (19%), and stalling is next with 23 (one complaint can fall under more than one problem, so these overlap). A quarter of the 12 owners who gave a mileage for diesel fuel system saw it by about 21,000 miles, and half by about 48,000.
- Crash, fire and injury reports
- 11 of the 162 complaints (7%) report a crash, a fire or an injury, about the 6% typical of vehicles on this site. Counted separately (one report can carry more than one), 5 reports mention a crash, 4 mention a fire and 4 people were hurt. The most crash reports, 3 of 5, fall under brake wear.
- Recalls behind the top problems
- Diesel fuel system, the one problem here with enough reports to check, has a recall on the same system (21V-880). A recall on the same system doesn't always cover the failure owners describe, so compare its summary with the complaints.
- When owners filed
- Filings peaked in 2022 at 47 (full calendar years only). In 2025 there were 14. So far in 2026, 10 more have come in.

How this compares
162 complaints is 1.4 times fewer than the median 2020 model on this site and about the median for a 2020 pickup. Among the 10 2500 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.
