Should You Buy a 2004 Toyota Sienna?

The 2004 Toyota Sienna is a reliable all-wheel-drive minivan that offers a spacious interior with seating for up to seven passengers, making it an excellent choice for families. With a 3.3L V6 engine producing 230 horsepower and 242 lb-ft of torque, it provides adequate power for daily driving and road trips alike. The vehicle's combined fuel economy of 18.0 MPG is reasonable for its class, especially considering its size and capabilities. However, potential buyers should be aware of the vehicle's MSRP of $37,150, which may be on the higher side for a used minivan from this era.

The NHTSA complaint data reveals 1,000 total complaints, including 26 crash incidents and 126 injuries. The most frequently reported issues involve the structure and body components, particularly the doors and latches, which may require attention as the vehicle ages.
