Visibility 33,000 mi 2.3 yr in service

LEAKING SUNROOF. THE FACTORY SUNROOF LEAKS DURING RAIN AND WASHING. IT HAS CAUSED WATER DAMAGE TO THE HEADLINER. ALSO THE REAR DRIVERS SIDE WINDOWS RATTLES AND HAS EXCESSIVE WIND NOISE. THE DEALER WANTED $90 JUST TO TAKE THE DOOR PANEL OFF I REFUSED BECAUSE I DON'T FEEL I SHOULD PAY FOR MANUFACTURE DEFECT. AS FAR AS THE SUNROOF GOES AN ATTEMPT WAS MADE TO REPLACE THE SUNROOF GLASS BUT THE LEAK STILL PERSISTS IN THE SAME LOCATION.

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
