problem #1

Jan 232004

Sienna 6-cyl

  • Automatic transmission
  • 20 miles
There is a sour smell (sulfur-like) coming from under the car. Dealer told us it is a problem with the catalytic converter, but as of 1/25/04, they don't have a fix for it. Said Toyota is aware of the problem. I would like to know what the problem is and when it will be fixed. This not only is polluting the air, but also could pose as a health hazard for those in and around the car.
