What Owners Say
"Check engine light was traced to the catalytic converter. It was replaced. The shop that replace it did not secure it properly so it was damaged and had to be replaced again."

Anonymous A., MN (2006 Toyota Sienna LE 3.3-L V6)"I bought this minivan at about 6 years/60K miles old. It looks like some work was already done previously on the manifold. The welding on the manifold came loose and manifold leaked. It was replaced, and re-welded."

"The catalytic converters (3) are not functioning properly causing poor gas millage. Replacements would run in the several thousand dollars and over the value of the vehicle. We have switched to the medium grade of gas as a stop gap measure which helps the millage some but the gas is more expensive. we are planning on selling the Sienna."
