Has any one else had this experience? Our 2021 Sienna XLE Plus side doors and rear door spontaneously open on random occasions, usually months apart. This morning, the driver’s side sliding door was open, in the closed garage—and was unresponsive electrically. I used the remote to lock the car and unlock the car in succession, but that door remained unresponsive. I manually closed it, and then it returned to normal operation. Three hours later I went out to the garage, and the rear door was wide open. Neither my wife nor I had bee out to the garage in between, nor had touched the remotes. This has happened four or five times in the 18 months+ Since we purchased the car. We took it to the dealer once at the 4 month point wit this experience, and they said everything was on spec!
