🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- ✅ Verify this recall: 12V auxiliary battery weakening, causing no-start or hybrid system warning lights. Make the seller prove it’s been done — an open recall is money off the price.
- 💸 Budget for this: Hybrid traction battery (NiMH) capacity degradation, especially in high-heat climates — $800–$3,500 if it goes. Check it on the test drive; if it’s near due, negotiate it down.
- 🧾 Your opening line: “2016 Toyota Priuss have known issues around this mileage — here’s my number.” Milo’s full report hands you the market price and a line-by-line offer script.

Which one to get — and which to avoid
✅ The one to get
2017-2018 Prius Three or Four trim with the lithium-ion battery pack, LED headlights, and Toyota Safety Sense — by then Toyota had ironed out the early brake actuator issue via recall/TSB fixes and the car had a full service history at a dealer.
🚫 Avoid
Very early-build 2016 units (built before mid-2016) with unresolved brake actuator/booster recalls not yet completed, and any car showing signs of hybrid battery cooling fan neglect (dusty cabin blower vents in the rear seat area).
