Body & structure
Van doors sensors not functioning correctly. Child was in the way and got pinned between doors. The door didn't stop when it touched the child, cont to close with the child in the way. Child ended up with a bruise on right thigh. The door had to manually be pulled back off of the child..
We have been to the dealer 3 separate times for our ac not properly cooling. And also no air flow through out the van. As well as the rear driver passenger door button doesnt open all the time.
Seats
Seat height not adjusting is ludicrous and a hazard! My husband is 6'4", my sons, 6'1", they seat height is not safe and braking/turns cause them to hit their heads. This could be life threatening in a real accident. There should be a lower profile seat that could be installed by Toyota. This is not safe!
While slowing to a stop sign at a normal speed, the 3rd row, which does not lock into place, flew into the upright position. Thankfully it had nothing on top of it, but if it did my children in the second row would have been seriously injured.
