Since I bought the car the power train has performed poorly. There was a long break in period with the adaptive 8 speed transmission. At 5-600 miles I took it to the dealer and a tech and service rep rode in the car. They told me the performance I experienced was from the 8 speed transmission.
Every time I take it to the dealer for maintenance I tell them it is our 7th minivan and by far it performs the worst of all of them. A couple of months ago I was in for service and they said they would contact corporate who I had to contact. Corporate tells me to take it to another dealer which would be two hours from us.
The car feels like it has a dead miss sometimes between 25 and 40 mph. Our neighborhood has a strict 25 mph speed limit and the car is quite annoying. The poor performance is also intermittent so I think it is correctable.
Over the years I have rebuilt GM Quadrajet carburetors, replaced plugs, points, condensers, water pumps, radiators, hoses, belts, and heater cores.
I still do my own brake and rotor replacements. I will do my own oil changes if necessary.
This is our second Sienna and the 2015 performed much better than our current car.
