Ordered by mileage. Severity and Milo's confidence in each finding are shown; VERY HIGH means it's tied to a documented NHTSA recall.

60kโ€“100k mi
12V auxiliary battery degradation causing no-start / dash warning cascade (common misdiagnosis as hybrid battery failure)
โ— Watch$150โ€“$300VERY HIGHdocumented (NHTSA recall)
80kโ€“150k mi
Brake actuator/booster (skid control ECU) failure โ€” triggers ABS, VSC, brake, and master warning lights simultaneously, sometimes with a whooshing/humming noise; code C1391

100kโ€“160k mi

120kโ€“180k mi
Hybrid inverter/coolant pump for the power control unit weakening, leading to reduced hybrid assist or warning lights
โ— Watch$400โ€“$1,200VERY HIGHdocumented (NHTSA recall)
150kโ€“250k mi
Traction hybrid battery pack capacity fade (individual modules weakening, not total failure)

Which one to get โ€” and which to avoid

โœ… The one to get

A 2014 Prius Three or Four trim (not base Two) with full service records, ideally a one-owner non-fleet car under 120k miles โ€” this keeps you ahead of the brake actuator and head gasket windows while getting nav/JBL audio.

๐Ÿšซ Avoid

High-mileage former rideshare/taxi units past 150k miles with no records โ€” they're everywhere, cheap, and usually hiding a brake actuator or head gasket bill about to come due.
