Buying a used 2020 RAM 4500? Check these 10 recalls first
Ten recalls cluster into two themes. The Cummins diesel side carries three criticals: engine damage with fire risk, a low-oil warning that may not appear, and stalling without warning. Brakes carry the rest — rear hoses that can burst, three more hose or line wear campaigns, one tied to LiquidSpring suspension kits, plus breakable wheel studs and loose wiper arms. None carry stop-driving or park-outside instructions. Only four owner complaints were filed with NHTSA, unverified reports, with no crashes, fires, or injuries.
Before you buy
- Get the 17-character VIN from the seller and run it at nhtsa.gov/recalls. It shows which recalls are still unrepaired on that exact car.
- Ask for VIN-specific proof all four brake hose and line recalls were completed
- Confirm whether a LiquidSpring suspension kit is fitted and inspect nearby brake lines
- Verify the engine damage, low-oil warning, and stalling recall repairs were performed
- Open recalls are repaired free at any RAM dealer, whoever owns the car — an open recall is a to-do item, not a bill.
