It is manual. Just happened out of no where. It only has 135,000 miles. I noticed other vans reported this problem with this year. I just had my car at the Whittier, CA Dealership. So far no answer, help!

As an interim measure, dealers will remove the spare tire and store it in the cargo area of the vehicle. Dealers will replace the spare tire carrier assembly when parts become available. It seams that Toyota is not following through on the parts and owners of the 2004 to 2011 Sienna's are lef...

The spare tire carrier cable may break due to corrosion from road salt. Dealers will initially move the spare tire and relocate it to the luggage compartment free of charge if parts are unavailable. When parts are available, dealers will replace the spare tire carrier assembly with an improved one free of charge to resolve the concern.

The shift lock system prevents the shift lever from being moved out of the Park position unless the brake pedal is depressed. These vehicles are being recalled because the shift lock solenoid could fail rendering the shift lock system inoperable. If the shift lever is moved out of the Park position when the brakes are not applied the vehicle could roll unexpectedly, increasing the risk of a crash. When parts become available, dealers will replace the shift lock solenoid to correct this concern.

The amount of adhesive applied between the inner and outer parts of the crankshaft pulley may be inadequate. If this is the case, the outer ring may become misaligned and/or not properly rotate with the inner ring, causing an abnormal noise and/or illumination of the Check Engine Light. In some cases, the power steering belt could come off resulting in a loss of power steering assist, increasing the risk of a crash. Dealers will inspect the crankshaft pulley and replace it if necessary.

The list of problems I have had over the years includes: - Heated Seats stopped working - Radiator had to be replaced - Lights on overhead console are completely out - Sunroof is cons...

I purchased a 2004 Sienna five years ago. So far, the unscheduled problems have been for the 2 rear seat belts not working and sliding doors getting stuck. I had to make the sliding doors manual by cutting the cable so we can open and close them. I called Toyota about the seat belts but they said that the warranty has expired. Are the seat belts supposed to last only 36,000 miles?? Other r...

I've had several issues with my 2004 Toyota Sienna XLE I purchased new. I have never missed a scheduled maintenance or oil change: the side door will not lock except manually from the inside, a $300 repair. The back life door has a mind of its own and will sometimes simply not close; one time this cost me a dead battery b/c after starting the close process (which is automatic), it was closin...
