My check engine light came on, so I took the car to the mechanic, they told me that I had an error p0402 catalytic converter malfunction. They told me that this is a known issue with the Nissan Altima and that Nissan knows about it and does not care to anything about it; he told me to google it and see the number of complaints online from Nissan Altima owners. I did just that and was amazed at how many complaints there were. The repair shop said that they won't fix it for fear of making it worse and told me to get rid of the car!.
