The 4500 and 5500 carry no year we flag to avoid. These are raw federal complaint counts, not adjusted for how many vehicles Ram sold, so they can't be read as a single cross-brand reliability score — use the per-model verdicts below.
What is the most reliable Ram?
Among the Ram models we analyze, the 4500 and 5500 carry no model year flagged to avoid in the current federal data — the cleanest records in the lineup. Reliability still comes down to the specific model year, so check the year-by-year verdict before buying.

Sources & data notes
All figures are drawn from the U.S. National Highway Traffic Safety Administration (NHTSA), Office of Defects Investigation — owner-filed complaints and recall campaigns — across the 5 most-documented Ram models and every model year on record for each. Retrieved July 2026. Counts are raw federal filings and are not adjusted for the number of vehicles sold or registered, so they cannot be read as a single cross-brand reliability ranking; each model year's verdict compares it only against the rest of that model's own history.
