I have read a couple of threads on this but not really go the answer, but, immediately after starting the car, one of the rear windows opens, the first three times it was the right but then the left did it, it only opens about 3 inches then stops but I also noticed that I cant turn on the childlock on the door that has opened until I turn the car off and on again. It has no pattern when it does it it just.... Does it when it wants.
