Good Minivan But Engine Humming Noise
By ChrisYL on


2009 Toyota Sienna LE 8-Passenger 4dr Minivan (3.5L 6cyl 5A)


Bought my 2009 Sienna LE in Dec 2008 in Orange, CA. Everything is good, drive smooth, roomy, comft. However shortly after driving, I start to hear engine humming noise, sometimes loud, sometimes not there. Happening specially at acceleration. My friend's 2007 has similar problem, others on Edmunds Discussion site mentioned same problem. Any of you seen this problem?

Best Features

Acceleration, Roomy, Comfortable

Worst Features

Engine or Transmission, wherever that humming noise comes from, cuz it can be loud.

Adjust the Heat Shield by the Rear exhaust manifold or catality converter. It will look tight but tell the tech to adjust it anyways.
