2018 Toyota Prius C recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Hybrid / EV system
What's wrong, in plain English: High-voltage battery or drive system. 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.
What could happen: A loss of drive increases the risk of crash.
The 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.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2018 PRIUS C.
- Book a repair at any authorized Toyota dealer. Quote NHTSA campaign 19V491000 (manufacturer code K0K).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-888-270-9371.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

The battery has a form factor (shape and size) that is exclusive to these vehicles and not used in any other car sold in North America. Vehicles with failed batteries (like mine) cannot be operated. Toyota should retrofit these…
