Questions to ask the seller
Questions worth asking the seller of this Kia before you buy, drawn from its public record:
- NHTSA lists 4 recall campaigns for the 2015 Kia Optima. Can you run this car's VIN at nhtsa.gov/recalls and confirm each one shows "Remedy Completed"? One is a "park it" / "park outside" order, the most serious kind, so I'd want that repair documented before I drive it.
- Owners of this model report engine problems more than anything else (owners tend to report it near 64k miles). Has this car shown any engine symptoms, and are there repair records for it?
- Owners of this model report electrical system problems more than anything else (owners tend to report it near 86k miles). Has this car shown any electrical system symptoms, and are there repair records for it?
- Has this car been in any accident or had any structural, airbag, or flood-related repair? Do you have a clean title and a recent history report (Carfax / AutoCheck)?
- How many owners has it had, do you have the maintenance records, and why are you selling it?
- Are you open to me having an independent mechanic inspect it before we settle on a price?
