I have taken my 2002 Sienna to the dealership (last winter) because the brakes have failed in very cold weather. The failure has happened three times, most recently this past Sunday morning. The first two times the vehicle had been parked outside in below zero temps for a few hours. I backed out of the driveway (no problem braking in reverse). . . All was well. However as I drove toward the stop sign it was as though the power was all gone from the braking system. I pushed them to the floor and held them there and eventually it stopped before I was too far out into the intersection. It has happened twice, under exactly the same conditions over the last two winters. The dealership could find nothing wrong. This past Sunday morning I had my two youngest children in the car and we were headed to church. As I began to brake for the stop sign ahead, again the same thing happened. I had to hold them to the floor and barely escaped entering the intersection. It frightened all of us. This time the car had been inside the garage. The first two times this happened I did research on the internet to see if anyone else was having this problem and found nothing. After this Sunday morning I looked again and now see that different and newer Toyota models have been found to have problems braking in cold weather. I can't help but wonder if I may be dealing with the same issue. I'm really hoping you can help me with this. I am afraid to drive this van, not just for our own safety but that of others. I don't trust it. I would appreciate a reply as soon as possible.
