Per the mechanic, a short in the electrical system has resulted in a melted electrical board and the entire head liner and electrical board needs to be replaced. The visor can not be used or the short may start a fire inside the vehicle. The vehicle…

Yesterday morning it was 31 degrees in atlanta and when i tried to open the rear hatch the rubber was hard and would not open the hatch. This could be a serious problem if in cold weather the vehicle was in an accident and the only access to the…

In november 2015 (90,000 miles) with vehicle parked, when opening the passenger side power sliding door, the cable snapped, binding the powered door's electric motor, and causing the door to be "locked in place" about 6 inches open. Went to driver side power sliding door, opened, children entered passenger compartment, and upon closing door this cable snapped, but…

I was getting things out of back with power lift gate up. While leaning in vehicle the power lift gate came down without warning and caught me. It did not continue to crush me but it did not reverse so i had to use a pretty good force to push it up (my wife probably would not have been able to do it). It did it a second time a week or so later. When i took it to toyota they said the struts were bad and replaced…

Passenger side power slide door does not work by pressing the button on the central console, on the side of door or the key fob. The slide doors do work by pulling the handles from the outsides. I was told this was the override procedure. This is a big concern with this being a family vehicle. *tr

I did some research on the internet and there are widespread reports of this being a common design flaw with toyota sienna automatic doors. I called the dealership and they indicated it was $1600 to repair the cable. That is outrageous! I wrote to toyota through their customer support site inquiring about an extended warranty i read about…

I recently purchased a 2008 toyota sienna that i believe has a safety issue, particularly in cold weather. The exterior switch that allows the rear hatch to open is not functional in cold weather due to a material malfunction. I noticed that during warmer weather, the rubber seal over this exterior switch had become soft and gummy. Over time, the rubber seeped between the switch housing and the switch button. As the…

My sister and i had just returned home from the store and i pressed the button to lift the back door to get our things out. We were in the middle of getting our things out when the door started closing on us. I got out and my sister got caught and it came down on her back and scratched her up pretty good. Ever since then just out of the blue it will not stay up and it will close down on you. I think this is a major…
