About the 2018 Toyota Sienna
The 2018 Toyota Sienna is a minivan that earns a Carivo score of 7.7/10 — rated Recommended. Its strongest dimension is Reliability at 8.7/10, while Performance at 6.1/10 is where it trails the competition most noticeably. It's a solid all-rounder that delivers across most dimensions without obvious deal-breakers.
Reliability and safety are the two dimensions that matter most for long-term ownership costs. Reliability stands out at 8.7/10. The Sienna nameplate has earned that score through its track record and a comparatively clean recall sheet. On safety, it scores 8.6/10 in our assessment. Always confirm the official crash-test results for your exact trim at nhtsa.gov/ratings.
Performance at 6.1/10 is a genuine liability and a score that should factor heavily into any buying decision. The powertrain and chassis dynamics trail class rivals by a meaningful margin — don't overlook it. At 7.4/10 for technology, the infotainment and driver-assist package does its job without setting benchmarks — check which features cost extra on lower trims.
Priced from $30,245–$39,800, 30 MPG, seating 8, the Toyota Sienna sits in the mid-market bracket of the minivan segment. At 7.5/10 for value, it delivers fair pricing for what's on offer, though the best alternatives in this price range score slightly higher. At 8 years old, resale value, parts availability, and whether a successor model has improved on its weak points are all worth investigating before committing.
Verdict: Nothing about the 2018 Toyota Sienna will scare a sensible buyer off. Keep an eye on performance if those matter to you; otherwise it does what a good minivan should — quietly and competently.
