Owner Complaints (6)
Your Sienna has been hesitating and idling roughly, with RPMs revving while parked. On one occasion, the van was shaking badly, wouldn't accelerate, and became undrivable. Even after a $725 gas tank flush and fuel injector cleaning at a Toyota dealership, the rough idling and hesitation have persisted. The issue may require further fuel system diagnostics or component replacement.

Your vehicle stalled while driving at highway speeds (60-65 MPH) with warning lights appearing on the dashboard. You were able to restart it and continue driving. The dealer replaced your fuel pump under a recall, but about a year later the same stalling problem happened again. The dealer couldn't reproduce the issue during testing, so no repair was made. The fix may require additional fuel system diagnostics or a replacement fuel pump assembly if the original part is defective.
