    We've been having problems with our Sienna lately. The van starts to misfire and throws a few CEL codes including misfires on four of the six cylinders. Our independent mechanic concluded that the problem was likely with the ECU/ECM/PCM. The independent suggested working through the dealer since...

    Hi. I have an '05 Sienna LE with 240,000km. Whenever I turn on the ignition it makes screeching noise that lasts for about half a second just right before I release my grip on the key. I try my best to release the grip on the key as soon as the van starts but I can't get rid of it. It...

    I must say that my 2004 Sienna has been largely trouble free (if you don't count the annoyingly noisy door-check "Click-CLACK!" problem - grrrr). But today I awoke to a serious problem that has me puzzled. Background: I drive the car occasionally - it is mostly used to go on family trips...

    Just bought it used from dealer. There was only one key, and the fob. Salesman said he'd look for any other keys. The one key I have only starts the engine...doesn't unlock the doors...or the the glove box. Only way to unlock doors or hatch is the fob. Can any '06 XLE Limited owners confirm...

    My 99 sienna started losing power and shuddering on a 3 hr journey recently. Eventually the CEL came on and stayed on after some intermittent appearances. I took it to the Toyota dealer and they diagnosed it as an faulty ignition coil based on the codes and switching the coil with another...

    the ignition key on my 2006 Sienna (161,000 miles) will not turn to the lock position, wont go past the acc position. I'm pretty sure it is because it is not recognizing that the shifter is in park - it does seem loose. Any ideas on how to troubleshoot/fix this? Thanks FM
