Recalls (2)

Safety recall repairs are free at the brand’s franchised dealers. Before buying, run the VIN at nhtsa.gov/recalls and make the seller show the work was done.

Hybrid Propulsion System · 19V491000

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018-2019 Prius C vehicles. The DC-DC converter may fail resulting in the auxiliary battery no longer receiving power from the converter, which may cause a loss of drive.

Risk: A loss of drive increases the risk of crash.

Fix: Toyota will notify owners, and dealers will replace the DC-DC converter with a new one, as necessary, free of charge. The recall began August 23, 2019. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is K0K.

Equipment · 18V176000

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018 Toyota Prius C vehicles sold in Puerto Rico. The front passenger air bag and recommended child occupant seating positions label may not have been attached during assembly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

Risk: If the label is missing, occupants may not follow the proper restraint usage guidelines, increasing the risk of injury in the event of a crash.

Fix: Toyota will notify owners and will mail the removable labels to all known owners of the subject vehicles, free of charge. The recall began on April 11, 2018. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is J0L.

Questions to ask the seller

Questions worth asking the seller of this Toyota before you buy, drawn from its public record:

  1. NHTSA lists 2 recall campaigns for the 2018 Toyota Prius C. Can you run this car's VIN at nhtsa.gov/recalls and confirm each one shows "Remedy Completed"?
  2. 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)?
  3. How many owners has it had, do you have the maintenance records, and why are you selling it?
  4. Are you open to me having an independent mechanic inspect it before we settle on a price?

The fine print: this verdict is computed from public NHTSA complaint and recall records for the 2018 Toyota Prius C as a model, not for any individual car. A well-maintained example of an “Avoid” can outlast a neglected “Buy”. Informational only, so always get a professional pre-purchase inspection.
