Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering visibility on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Safety Recall completion is important not only in satisfying government requirements but also is an integral part of our commitment to meet customer expectations of Toyota products. Toyota will be sending Safety Recall Follow-Up Notices to remind owners whose vehicles have not yet had campaign repairs completed. We request your assistance in completing the applicable campaign repairs as owners receive the Follow-Up Notice and contact your dealership. Please note the follow-up activity may cause an increase in your current campaign owner appointments. Toyota will continue with additional follow-up activities in the months to come. Please take this into consideration when analyzing your manpow

The failure pattern owners describe
Owners describe a cluster of glass and visibility failures across the 2006 Sienna. Side and rear passenger windows have shattered spontaneously without impact—one owner reports it happened five weeks after purchase on a Sunday drive, with glass exploding into the cabin. A dealer in the same region confirmed a second similar incident within weeks. Another owner's rear driver-side window shattered in slow highway traffic with no collision involved.
Windshield problems show up as optical distortion concentrated in the lower left corner, causing eye strain, watery eyes, headaches, nausea, and dizziness. Toyota dealers explicitly refused replacement, telling owners "all Siennas are like this."
Side mirrors on multiple vehicles become loose and won't hold their adjusted position, creating blind-spot visibility gaps that owners describe as a safety hazard during lane changes. One owner who owns two 2006 Siennas states both vehicles experienced mirror failure on both sides.
Sunroof issues range from a mechanical problem where the closing mechanism retracts at highway speeds over 45 mph (and extends when the vehicle slows), to one case where the sunroof blew out completely at 60 mph on a highway, ejecting glass onto the driver and passenger. A dealer confirmed another 2006 XLE Limited exhibits the same speed-dependent sunroof behavior and said there is no fix. One window also fell out during remote closing operation.

Failure modes owners describe
Side and rear passenger windows shattering spontaneously
Multiple owners report side and rear passenger windows exploding or shattering without impact, collision, or external cause while the vehicle is in motion or at rest. Glass breaks into small and large pieces, falling into the cabin.
When: Within first weeks of ownership; no pattern tied to mileage
Symptoms owners cite: Window shatters spontaneously without impact; Glass fragments fall into cabin; No external cause or collision detected; Window closed before failure
Repairs/costs cited: Dealers replaced windows under warranty; no structural fix identified
Windshield optical distortion
Windshield exhibits optical distortion in lower left corner and across pane, causing vision problems and physical symptoms. Toyota dealerships claim this is a manufacturing norm and refuse replacement.
When: Early ownership; failure noted by November 2006
Symptoms owners cite: Optical distortion visible in windshield; Eye strain; Watery eyes; Headaches; Nausea; Dizziness
Repairs/costs cited: Dealers refuse replacement, claiming defect is normal for Sienna model
Recalls/TSBs owners mention: Toyota stated all Siennas have this distortion and would not replace windshield
Side mirror mechanism failure
Side mirrors (driver and passenger) become loose and cannot maintain their adjusted position, rotating out of place and causing loss of blind-spot visibility.
When: No specific timing noted; appears during normal use
Symptoms owners cite: Mirror becomes floppy; Mirror will not hold adjusted position; Loss of blind-spot visibility; Mirror rotates out of place while driving
Repairs/costs cited: Expensive to repair; owner notes high repair cost
Sunroof mechanical malfunction at highway speeds
Sunroof closing mechanism moves down while vehicle is in motion at speeds over 45 mph, retracting when vehicle slows. Dealer confirmed other 2006 Siennas exhibit the same behavior.
When: During normal highway driving
Symptoms owners cite: Sunroof mechanism retracts at speeds over 45 mph; Mechanism extends when vehicle slows down; Occurs while driving
Repairs/costs cited: Dealer test-drove another 2006 XLE Limited and confirmed same issue; no solution available
Recalls/TSBs owners mention: Dealer stated no solution exists for this defect
Sunroof explosive failure
Sunroof exploded or blew out while vehicle was traveling at highway speed, ejecting glass into the cabin onto driver and passenger.
When: While driving approximately 60 mph on highway
Symptoms owners cite: Sunroof blows out; Glass falls inside van and onto occupants; Occurs at highway speeds
Repairs/costs cited: Temporarily sealed with tape by glass service until warranty/insurance reviewed
Side window fell out during remote operation
Rear passenger side operable window fell out of frame while being remotely closed.
When: During window closing operation
Symptoms owners cite: Window fell out during remote closing; Window became inoperable
