I am a new forum user. I have had the same problem with my '02 Sienna XLE van. It is the ONLY problem I have ever had. We love the car but the dealer has never found the problem because it hasn't acted up when it was at the dealer. Besides being annoying, I am concerned that there is a possible electronic issue which might lead to more serious issues. Not sure what to do next. I am hopeful I can get it into the dealer while it is happening.

My 02 just started doing it today. It lockes itself every few seconds. Sometimes it is often enough that it is hard to get the door open before it locks again. I'm taking it to the dealer as soon as I can. Maybe it's a Minnesota thing. Did you take yours to the Burnsville dealer or another one? It would be funny if you decided to trade it in and I have the same van. I just got mine in May. I'll let you know what they find.

It ended up being a failing battery that was providing low voltage. Another thing it was causing was teh ABS, VCS, and TRAC off lights coming on when idling.
