2006 Toyota Sienna Complaints

The TPMS system failed in the ECM or engine computer. It uses the wheel speed sensors on each hub to measure differences in wheel speed and uses this to infer if any one wheel has low tire pressure. (This vehicle does not have TPMS sensors in the wheels.) However, with this failure, it reports a tire pressure problem even though all 4 tires are inflated properly. This problem persists even after cleaning then replacing wheel speed sensors. The problem appears to be in the ECM or engine computer, which is very difficult and expensive to replace. With this problem, the driver is never able to tell if any tire actually has low pressure because the system always reports that a tire has low pressure. Toyota should be required to fix this issue in all affected vehicles.

While driving, there was a recurrent sound like doors locking and unlocking, several dozen times over a half hour drive at 50 miles per hour. When stopped, the passenger side sliding door opened by itself. Luckily, my dogs were in a kennel or they might have jumped out of the car. I closed it and it opened by itself again. At home, the passenger side sliding door opens when my neighbor presses the button on his key fob to open his non-Toyota pickup truck. It will not open or close when I press the button on my Sienna key fob.

I am contacting you regarding Toyota Warranty Enhancement Program – ZE6. This concerns sticky and cracking dashboard and glare from this. I had no idea this existed. I own a 2006 and a 2010 sienna. I have not received any mailers from Toyota regarding either Sienna's . My van's dashboards are included in this program. Problem is, I never received notice from Toyota about either dashboard. Is there anything that can be done about this?
