2018 Toyota Sienna Owner Comments

problem #1

Apr 012019

Sienna LE 3,5 V6

  • Automatic transmission
  • 16,000 miles

Not getting mileage expected with 8 speed tranny, city miles 15, highway 20, highway speed average 65, tranny is erratic on acceleration.

Update from Feb 19, 2020: 25,000 and milage sucks, only time OK is doing 55-60mph flat surface in 8th gear rpms 1200 then you see 25-27 according to computer, you gotta clear settings and clip every time you start trip to accurately see MPGs, great if you drive real slow for long distance. Engine seems noisy too
