2000 Toyota Tundra exhaust system problems

While driving, consumer can smell exhaust fumes coming through cab of vehicle. Have yet to contact dealer. The consumer was complaining about road noise while he was driving. Also the radio was of no use because he can?t hear when the vehicle speed was above 40 MPH.

I have had one oxygen sensor replaced within the past year at an expense of over $400. I now have another oxygen sensor failure and note that many others are experiencing the same manufacturer defect. My truck has only 52,000 miles but it is beyond the extended warranty period granted by toyota. It is obvious that toyota should recall all 2000 tundras and fix them rather than extend a warranty.
