About the 2nd Gen
The 2004-2010 Toyota Sienna is the second generation of the minivan and grew dramatically over its predecessor, matching the largest vans in the class on interior volume. Engines were the 3.3-liter 3MZ-FE V6 and, from 2007, the 3.5-liter 2GR-FE V6, paired with a five-speed automatic. Front-wheel drive was standard and this generation introduced an all-wheel-drive option, unusual in the segment at the time. Seating for seven or eight was offered depending on configuration.
This was the first Sienna to be genuinely competitive with the Chrysler and Honda minivans on size and features, offering power sliding doors, a power liftgate, and available rear-seat entertainment. The 2GR-FE engine introduced for 2007 is a meaningful upgrade over the earlier 3.3-liter. The third generation that followed in 2011 refined the formula rather than reinventing it.
As a used buy, this generation is valued for space and the durability of the 2GR-FE V6, which is one of Toyota's better-regarded engines. All-wheel-drive models of this era were fitted with run-flat tires and no spare, which raises replacement costs and is worth factoring into ownership. Power sliding door cables and motors are the most common repair across the generation. Oil cooler line failure on the V6 is a known item that is inexpensive to prevent and expensive to ignore.
