Recalls & safety
Recall history hasn't been loaded for this model year yet.
Whether a recall is still open on a specific car depends on its VIN. Check it free at NHTSA's VIN lookup (nhtsa.gov/recalls), or ask the seller for proof the repair was done.
Pros & cons
Pros
- Low running costs; average annual repair spend well below the midsize-car class average
- 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
- First-year-of-generation teething and a high incidence of costly brake-actuator repairs

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 ($21,400). Higher trims started higher (up to $28,070), 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.
