Getting a service engine soon light and code says to replace catalytic converter
I just bought this car. The check engine light is on. When I check the codes from the computer it states a problem with catalytic converter. I was told there is a recall on this item. How do I get it fixed?
Check engine light came on last week and took car to dealer the next day. They checked and said that they would have to order part, waiting on call to see if it came in.
Well, part finally came in and I took car to local Nissan dealer. Took the tech about two hours to change the converter and while he was at it also replaced master cyl under TSB that I didn't know about. I noticed a vast improvement while leaving the dealership as far as pep. I took the car for a long test drive and noticed more than a 4 mpg difference. Best of all, it didn't cost me a cent!
I was told the same problem but I don't know who to trust. Where should I take it?
check engine soon light came on. They said it was 1 of 4 things. Large vacuum leak, fuel system fault, ignition system fault and failed bank 1 catalytic converter.
Service engine light came on, took to a shop who hooked up the diagnostic tool and it said it was the catalytic converter. Have to replace total cost 660.00
One day I saw my check engine was on and went to go take it in. At the shop they told me my catalytic converter needed repairs. I was just wondering do i get it replaced or fixed?

Bought this car 4 months ago and the service engine soon light just came on. Turns out the catalytic converter's bad and i'm looking at a $600-$700 bill to repair it. Been driving beautifully, but I wonder how long I have to make this repair before that changes? I don't understand why this issue hasn't prompted a recall by Nissan if so many ppl are having it.
check engine light code was identified as the front catalytic converter by a third party.
We took the car to the dealer. Found out there is a service bulletin dated 2009.
they will verify on Wed. If cat. is found to be defective dealer will repair at nissan expense.
I have had to have 3 catalytic converters replaced on my 2008 Nissan Altima because of this issue.
Check engine light went on. I took the car for a code check and it came up with the code in this article

code p-0420 cat-converter problems
Had Engine code P0300. Investigated problem. Found coil packs that go to spark plugs not seated tight enough to wiring harness. Used plastic tie straps to hold coil packs tight to wiring harness. Check engine light has been out for 3 weeks now.
Catalyst converter needs replacement.
