2004 Toyota Sienna Problems

Models with electric sliding doors can develop problems with the door mechanism. The cable in the door becomes frayed, which will damage the electric motor.

Multiple cracks may develop on the upper surface of the dashboard. At this time, the only suggested repair is to replace the dashboard.

One or more oxygen sensors may fail resulting in illumination of the Check Engine Light.

2004 Toyota Sienna Recalls

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.

Toyota is recalling 1998–2010 Sienna models manufactured or registered in twenty-two Eastern and Midwestern states because of problems with the spare tire carrier and assembly cable due to road salt corrosion. This may cause the spare tire assembly cable to break and the spare tire to separate from the vehicle, increasing the risk of a crash. Toyota will notify owners via letter with instructions on how to remedy the problem. For a list of the affected states, call Toyota at 1-800-331-4331.

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...
