I had my catalytic converter replaced last year only to be told I needed another one this year. Shouldn't it be covered under the warranty? Could you help me?

I have seen up to 3 converters, all depends on the engine style, 2 pre converters and 1 main. As far as warranty that all depends on where you bought it, after markets usually 90 days, some dealerships will cover it for 12 month or 12000 miles, but not all. So you need to find out what converter was replaced, and which converter is bad now. If the converter that was replaced is the same one that has went bad, then you need to find info about the warranty. Then you need to find the real problem as to why it is going converters.

Titans have 4. One built onto each exhaust manifold and one below each of those.In canada the warranty is 8 years and 130000 km. may still be under warranty.


We are having issues with our 2009 Titan, which he fell in love with the first time he test drove it.. My husband did alot of research first with all the trucks ever made test drove all of them see what deals they can give considering we are Military. Ford was the worse even though we like there truck alot and went back and purchased the 2009 Nissan Titan with only 15 miles on it because not only did they take care of Us they also, gave my husband a huge Military discount and we paid 12 grand less on the sticker!! Well, 5 years later, he took his truck to Nissan to get diagnosis. Not one but BOTH catalytic converters went bad because of there sensors. Hubby called me and said that Nissan said that it will cost of 3 grand to replace the converters, that almost gave him a heart attack. I told him to hold on and I was going to call Nissan. I recieved a call back from a young lady who told me she would do her 'investigation' and get back to me in 3 days. Well, I got the call this morning which is the 3rd day and said no can do on helping us on the cost because we are over 2,000 miles on the warranty. My argument to her is, converters are suppose to last the lifetime of the vehicle and we can see replacing one but two with two bad senors? Doesnt make sense whatsoever. Im highly upset and her answer was," Im so sorry." No compassion nor no other offers of an options besides, your screwed. I hate Nissan and I dont like the way they do business. I was highly upset and hung up on her.

I would suggest going to an independent garage to get a second opinion, try to find one that is ASE certified, talk to your friends find who they use, check the reviews of shops in your area. They may have an alternative instead of the dealer. That price seems to be quite high to me even for a dealer. Sometimes it turns out to be something else.

I had to replace two on my Titan as well.What I found out is the faulty fuel pump burned them out.It would sputter when gas was at quarter of a tank.Wish I had known to replace the fuel pump before that ct converters burned out, a lot cheaper. The titan would only stall when the fuel pump got hot, on trips over 100 miles so they never were able to diagnose the problem on atest drive


That sounds about right I have a 2004 titan i just bought with 103k miles on it and I just got the code p0420 so I have to replace mine even though not all are bad while they have the engine out im gonna replace all 4 I've had two prices 3k and 2.2k the 3k was from nissan and the other a private garage
