A Toyota Sienna engine can last between 200,000 to 300,000 miles with proper maintenance, including regular oil changes and timely repairs. Many owners report their Sienna engines reaching these high mileages, thanks to Toyota's reputation for reliability. Factors such as driving habits, maintenance practices, and environmental conditions can also influence engine longevity. Regular check-ups and addressing issues promptly can help extend the life of the engine.
