2023 Toyota Sequoia

Posted
By Research the Car 3 min read

The 2023 Toyota Sequoia represents a significant redesign for the model, moving to a fully boxed frame and a new powertrain. This generation Sequoia ditched the old V8 in favor of a turbocharged 3.4-liter V6 engine, paired with a 10-speed automatic transmission. The standard engine produces 437 horsepower and 583 lb-ft of torque. Owners often praise the Sequoia’s comfortable ride, spacious interior, and strong towing capability. However, common complaints include the complicated infotainment system, some interior material quality issues, and concerns about fuel economy given the turbocharged engine.

Engine

3.4L Twin-Turbo V6 (i-FORCE MAX)

  • Turbocharger Failure
    • Description/Symptoms: Some owners have reported premature turbocharger failure, resulting in a loss of power, unusual noises (whining or whistling) from the engine bay, and potentially a check engine light.
    • Solution: Replacement of the failed turbocharger.
    • Estimated Cost to Fix: $2,500 - $4,000+
    • Recalls: None Found

Summary

The 2023 Toyota Sequoia, while generally reliable, has experienced a few common issues, particularly related to the new turbocharged engine, 10-speed transmission, and infotainment system. The turbocharger issues and transmission problems could be considered more severe and potentially costly to repair. Electrical glitches in the infotainment system can be frustrating for owners. While these issues exist, they do not affect every single vehicle and Toyota has been known to address common concerns via technical service bulletins (TSBs) and software updates. Potential buyers should be aware of these common issues and thoroughly inspect any used 2023 Sequoia before purchase.
