I have a 2000 Tundra access cab truck with 62,000 miles. The check engine light came on so I had it diagnosed. The front O2 sensor before the cat has failed. I wrote Toyota and they said that they had extended the warranty to 7 yrs or 90,000 miles. They said that it was also up to the local dealer to decide if the fault would be covered. I purchased this vehicle from a relative, who is now deceased, and did not receive any recall info. I wrote to Toyota and they told me to talk to my local dealershp. I talked to the local dealer and they told me to write or call the Toyota experience department, or what ever it is. From what I have read there are a lot of people getting ripped off for a defect in factory provided parts and replacement parts. I definately think this is a design flaw and should be covered by Toyota. I for one can not afford to own a vehicle that is going to cost $200 to $800 every 6 months to 2 years. This also affects the environment and the fact that this vehicle has to be smogged every 2 years.

At 80,000 miles my transmission needs to be replaced. I have never abused this vehicle in any form and feel that Toyota should reimburse the many thousands of owners who seem to be having the same problems with this model. For the amount of money these vehicles cost it only seems fair that Toyota should be forced to stand behind their products.

Both left and right exhaust manifolds are cracked and leak exhaust gases into passenger compartment. Right exhaust manifold has been replaced. Because of cost, left exhaust manifold has yet to be replaced.

My 2000 Toyota Tundra limited V8...O2 sensors need replaced (all 4 of them)...this is an apparent problem and should be a factory recall item. This is a $850 dollar job...ridiculous! check engine light comes on and codes out as oxygen sensors.

3 pairs of cracked exhaust manifolds in less than 100K miles. Had I been more vigilant about repairing them as soon as they occurred, it likely would have been another couple of pairs. Dealer replaced them up to 100K, and although I pressed them for a solution, they would not honor problem after 100K miles.

Cracked exhaust manifolds, have heard the noise for quite some time. It has gotten worse but goes away when the truck warms up.

I have an oxygen sensor failure. Don't know if it's one or both on the right side. Will cost well over $400 to fix. Have heard of several other having the same issue.

My 2000 Tundra trd 4X4 V-8, auto trans developed an engine noise within the first 10,000 miles and first year of ownership. I took it to the dealership, godfrey Toyota of Cadillac, mi and they were unable to identify the problem. At approximately 78,000 miles, the O2 sensor failed, as identified to me by the check engine light. The dealership service department replaced my sensor, and initially billed me for the work. When I asked the mechanic, he identified the occurrence of an extended service bulletin on the O2 sensor. He further identified the reason for the noise was the cracked manifold, that had apparently occurred within the first 10,000 miles of driving. He indicated the noise was worse when the engine was cold and that after driving awhile, the cracked tended to close up and reduce the noise. He further indicated that if the O2 sensor had not come out, that Toyota would have replaced the manifold and sensor at the same time, at no charge. My chief concern with the cracked manifold is the possible reduction in life of the engine due to exhaust leakage, secondarily to vehicle occupants during any extended idling, something I personally do not often do.

: the contact stated at 20,000 miles while applying the accelerator at various speeds there was a spewing noise and the odor of fuel coming from the vehicle. The vehicle was taken to the dealership, which determined the exhaust manifold needed to be replaced. Although, the exhaust manifold sensors on the passenger side were replaced three times the exhaust manifold had never been replaced. The odor became worse and now is causing dizziness and headaches to the occupants. Updated 7/3/2006 -

The headers near the engine have little holes in them allowing there to be an exhaust leak and a loud noise.

Having to replace O2 sensors with regularly, 5000 miles intervals. Dealers states this is common problem with this truck. Need to investigate and recall. Very expensive part.

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.
