Toyota Sequoia Reliability by Year

Every gasoline Sequoia model year from 2004 to 2021, scored on reported failures weighted against how many were sold — and ranked against every other Large SUV of the same year.

Scored separately as its own vehicle: Sequoia Mild Hybrid (2023–2025).

The short answer

Best model year
2015
#1 of 29 that year
Year to avoid
2005
#26 of 28 that year
Latest scored
2021
#5 of 33

Across 18 scored model years the Sequoia rarely gives trouble, but repairs run costlier than average when it does. The spread between years is what matters: 2015 is its strongest, 2005 its weakest.

Every model year, scored

Longer bar is better. Rank is against every Large SUV sold that same model year.

The line held a weak position through 2006, ran middling in 2007, and has been strong from 2008 on. The recent trend is upward. This 2021 car falls in a strong stretch.

What tends to break

All 12 systems, measured against the class average for each model year.

Every Sequoia model year is scored across 12 separate systems — engine, transmission, brakes, electrical, steering and suspension, structure, interior, and five more. Each system is compared against how often that same system fails on the average Large SUV of the same year, so a common failure is judged against how common it is everywhere else.

Where does this data come from?

Failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes so a high-volume model is not penalised for selling well, then benchmarked within segment and model year.

How this was built. Scores derive from failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes and benchmarked within segment and model year. We measure two separate things: Fix Frequency — how often a vehicle needs fixing — and Fix Severity — how costly those fixes are. These figures describe a model line, not the specific vehicle in front of you; trim, mileage and service history still decide an individual car.
