“In 2003, I was told the ecu unit needed replaced on passenger side rear power sliding door as door would intermittently not open or close. Has continued with intermittent problem until it finally wouldn't open nor close. Given the very high volume of complaints about this problem on all years of the Toyota Sienna, I would like for the odi to open an investigation. All you have to do is google Toyota Sienna power sliding door problems and you end up with multiple thousands of hits, with most being chat sites with multiple complaint threads.”

“All the locks keep unlocking, and locking without anyone in or around the vehicle, because locks are locking and unlocking it is causing the battery to drain. The doors lock and unlock while van is in gear, while driving, and when van is not running without key in ignition. I have 2 children and believe this is a safety issue!”

“Automatic sliding door on Toyota Sienna often does not close. Even when encouraged manually to close, it pulls back several times. If auto feature is turned off, it won't pull closed at all. Sliding door on left side won't open from inside. Occasionally locks itself so that it can't be opened from outside either, even if all other doors are unlocked.”
