Attention: Safety problem / design flaw in order to listen to the stock Toyota dvd player that comes factory installed through the van's cabin speakers, the volume of the stereo must be turned almost all the way up to a volume of over 53. The other audio source (cd, radio, tape) are normally listened to at a volume of about 34. When the dvd player is stopped and another audio source (cd, radio, tape) is played, the volume level in the van instantly becomes deafening and startling. This has happened several times in which the driver has been startled to the point of almost loosing control of the vehicle and temporary hearing damage of several occupants has also resulted. This design flaw has been brought to the attention of the local Toyota dealership on two occasions. They have been in contact with the Toyota factory engineers and they were told that this is "normal" operation and no corrective action by Toyota has been indicated. This is definitely not "normal" as a vehicle collision or hearing damage should never be the direct result of changing the audio source. This is a serious problem T that should result in a expeditious recall that results in the equalization of the volume levels for all audio sources (dvd, cd, radio, tape) in the vehicle.

This is regarding the 2004 Toyota Sienna minivan. It is not a failure, but a design flaw that can be corrected by replacing a component or adding new components. When the audio on dvds is played through the aux in-cabin speaker system, the volume must be set at about 50 to hear it. The sound system does not include a memory recall for the volume of each source. The result is that when the dvd is turned off, the sound system defaults to radio or cd, at a tremendous volume that hurts the eardrums and also presents serious danger because of the distraction to the driver from the sudden booming volume, and its effect on the driver and passengers, including infants. Toyota should recall the van and install new components-- more specifically, memory components to control the volume of the various audio sources being routed to speakers (cd, radio, dvd). Nothing as been done yet by the dealer to correct this, though an inquiry to Toyota hq remains outstanding.
