Great car, but uncomfortable seats
 Just got the Toyota Avalon limited with cooled seats. There is a design flaw in the seats as they are very uncomfortable with the cooling bars under the padding. I noticed it the next day while driving. Service made an adjustment, but not enough and both sales and service agree that there is a problem. However, it seems to be a design of the seats. I consider it a flaw I am now contacting Toyota to see what can be done about it. The service tech told me Lexus uses the same system but the seats have more padding. I would try out the driver seat for an extended time before purchasing one that has a cooling option for the seats. I wouldn't buy it again because of it.
