Common questions

Is the 2020 RAM 4500 reliable?

Mostly yes. With a reliability score of 8.4 out of 10 based on 3 owner complaints filed with NHTSA, the 2020 RAM 4500 is generally a sound vehicle. The areas to watch are listed in the top problem section above — most are budget items, not deal-breakers.

What's the most common problem on the 2020 RAM 4500?

No problem area has crossed our reporting threshold yet, which is a good sign for this vehicle.

What's the most expensive thing that goes wrong?

Major repair items haven't been flagged often enough on this vehicle to single one out.

How do I check if my RAM 4500 has open recalls?

Paste your VIN into the decoder at the top of this page. We pull live from NHTSA, so you'll see exactly which campaigns apply to your vehicle and whether the dealer has logged the fix. Recall repairs are always free regardless of mileage or warranty status.

Is an extended warranty worth it on a 2020 RAM 4500?

Math is straightforward: a quality service contract runs $1,800–3,500 over 3 years. With 3 complaints on file, one major failure more than pays for it. The catch is reading the contract — many providers exclude wear items and require pre-authorization, so cheaper plans aren't always better value.
