The power sliding door on our 2004 Toyota Sienna is faulty. It failed in the open position. My wife had to drive my kids plus neighbor kids home with the door stuck open. This is truly a safety concern. Now, only a strong adult can get the door open or closed. Also, the center hinge on the door is faulty and has ground away the paint and metal on the body right below the track the door uses to open. Apparently, Toyota sort of recognized a problem with this (there have been many complaints about it) because they issued an extended warranty to cover this very problem. However, the warranty expired a year ago, and my door didn't fail until very recently. I called and they said there is nothing they can do. The warranty period is over. The problem with the warranty is that it puts the onus on the owner to recognize the problem (paint being rubbed off and then metal) or a major failure (the door being stuck open). Will it take a serious injury or some child falling to her or his death through the open side door before Toyota acts responsibly and issues an actual recall?.
Passenger side automatic sliding door requires manual force to assist electric motor during opening and closing. Door appears out of vertical alignment and impacts car frame during opening procedure. Exposed metal occurs where door has rubbed paint off of frame.
The first incident is that the passenger side sliding door started to rub the paint off the body, so we disabled it since the dealer said it was out of warranty and would cost us $1800. A couple years later the driver side sliding door seized and wouldn't close. I had to drive to where my wife and kids were stranded and cut the door's cables, so she could drive home. A couple years after that I receive an extended warranty letter from Toyota for their sliding doors, however, since there is a 120,000 mile stipulation and ours had more miles than that they said sorry we are out of luck. Toyota extended the warranty because they knew there was a problem with their sliding doors, but set stipulations, like mileages, so many people could not take advantage!!! I also had a problem with the driver's door hinge weld breaking, the dealer once again told me there was no recall and it would cost me a few hundred dollars to weld it back together. After looking at the hinge's weld I could tell it was an assembly misstake. Since I know how to weld I removed the door myself and re-welded the hinge. Several months after fixing it myself I found out there was a recall.
