2015 Sienna downgrade from 2004 Sienna
 This is a very nice people mover with good performance and features. It replaced a 2004 Sienna which was great. Simple changes like reducing the size and capacity of the roof rack and seating changes makes it less useful than the 2004. We expect the same reliability - the 2004 went 225 miles with no problems. The transmission went and cost $4400 but we got to 335K miles and sold for $1400 after the rebuilt transmission also failed. The sliding and folding seat mechanisms are an improvement. The climate controls are unnecessarily complex. Changing to a timing chain should reduce maintenance frequency and cost. Overall, this is a vehicle I would recommend. After about 85,000 miles it is still performing well with no major problems
