Owner Complaints (2)
Your Sienna experienced sudden jerking and complete loss of power while driving, and on multiple occasions the engine shut off on its own. Even though the fuel pump was replaced under recall in 2020, the problem came back and has continued to happen. The dealer couldn't reproduce the issue during testing, so the root cause remains undiagnosed.
