Recalls & safety

Pros & cons

- Outstanding hybrid fuel economy, among the best of any non-plug-in car
- Practical hatchback body with flexible cargo space and easy city maneuverability
- Legendary Toyota hybrid reliability and longevity, commonly reaching 250,000-300,000 miles with maintenance
- Durable nickel-metal-hydride hybrid battery that frequently lasts well past 150,000 miles
Cons
- Noticeable road and wind noise at highway speed
- Uninspiring acceleration and driving dynamics; the eCVT can drone under hard throttle
- Engine EGR-cooler/head-gasket vulnerability at higher mileage

Depreciation
Move your cursor along the line to see the estimated value for any year.
This listing sits above the typical depreciation curve. Common for heavily-optioned cars and for 2021-2023 model years (pandemic-era pricing); the curve is anchored at base MSRP, which excludes options.
Curve anchored at the entry-trim base MSRP ($22,120). Higher trims started higher (up to $28,790), and options added more.
The curve's data ends 10 years in, so the line levels off after that. Treat the tail as a floor, not a forecast: asking prices for older cars depend mostly on condition, mileage, and the current market, and often sit well above it.
