    IIRC Toyota has a longer emissions control warranty. I had my scion cat replaced at 73K for free...Might be worth looking thru your paperwork/researching a bit (unless you have a line on some repalcements)

    There is a federally mandated warranty on emission components for all mfgs. Not sure if all parts have the same warranty but believe it's something like 8yr/80k or 100k.

    I had an o6 with the same issue, there's a TSB out there and your truck is covered to 96months/80k. Check it out its called ticking noise TSB I think. BTW, Im going to jack your title and start a thread of CAT's Failing. Hope you dont mind.

    As others have stated, the warranty on Catalysts and Computers (hardware) are longer than the base vehicle. The minimum is 8/80 and should apply to our trucks. Some vehicles, depending on emission certification level, will carry longer 10/150 and some states have regs that are pushing the numbers up.

    You said your Cats blew. What does that mean? Did both cats set a code at the same time? If so, I find that highly suspect. Just because a vehicle sets a code for a catalyst having low performance does not always mean it is the cat. How many miles do you have on the truck and how well has it been maintained? Do you have records of plug changes and so on? Your truck is able to set a code for each bank of the engine. To have both flag at the exact same time can indicate another issue.

    For extra information. If you ever see a check engine light that flashes at you, stop driving. That is a special mode of notification that a severe enough misfire is present that will cause damage to the cat. It can happen in a VERY short time turning a potentially small repair into a very large one. The warranty does not cover abuse, so if you take a vehicle in with misfire codes or no maintenance records the coverage on the catalysts could be rightly denied.

    I for one would appreciate more information from the OP on this truck.

    Thanks

    Use a can of SEA FOAM once a month in the gas, keeps everything clean and burns off the stuff in the Cat's (MEOW) I was told about it from a buddy that works at Lexus, they use them on those high dollar Toyota's, also keeps your mileage in check. Good luck.

    Thanx for all the tips ! to answer a few of the questions my truck has 114k miles on it and has never seemed to misfire not enough for me to tell anyway.
    The check engine light just came on one day so I took it to my neighborhood mechanic and we found it was one of the cats so we reset the light and he told me to come in if it came on again and note the millage when it happened just to be sure that it was in fact the cat, it came on again in about 200 miles and this time it was the other cat on the opposite side as well .
    As for proper maintenance I am the second owner so I cant be sure of its previous maintenance schedule but I definitely keep up on it. On thing I haven't done is change the spark plugs witch I herd suggested! I just don't know if its too late and the damage has already been done.
