Hey guys i just got my 2014 Q50 with 103k and a week after getting it i got a check engine light which ended being the P0420 code i know its the catalytic converter but is there any way i can fix? I have a warranty on the car but I don’t know if that will cover will have to look into it car drives fine but worried because i have emissions in a month i will probably end up taking the car to a infiniti dealer

According to the link above, it could also be a dirty air filter or an O2 sensor. Those are certainly cheaper. I’d check the air filter myself real quick, should only take a minute to make sure it’s not dirty. It shouldn’t be hard to check the O2 sensors yourself either. You’ll have to get under the car, unplug the sensors and read their resistance with a voltmeter. I’ll have to look up later what the resistance should be, unless you search it out yourself or someone else here knows off the top of their head.

If all those are alright, then yeah, it’s gonna be the bank 1 catalytic converter (and it probably is I’m sorry to say). In that case, don’t go to Infiniti unless you want to sell your fist born! Go to a local muffler shop and tell them you need a catalytic converter. Unless your warranty covers it, it’ll still hurt, but Infiniti will buttfuck your soul over it.

Correction: this is not a roadblock, it's an opportunity. Get a FDP + tune, unleash the power of this platform.

Pretty sure the US has emission regulations that cover Catalytic converters for extended periods but that may be only for around 80K Miles.
But yeah exhaust shop over a dealership if the cost is going to come out of pocket.

If you're in a state like commiefornia, be sure to get the correct cats that have 50-state CARB-compliant or else you will be wasting your money (will fail visual smog). Sucks, but way it is here. Believe at least NY is similar, perhaps other states...not sure but worth checking into.

I put hi-flow cats on my X and they worked well enough to not trigger the CEL, but would've failed the smog test. Shame, 'cause they were way cheaper than the "legal" ones and especially the ripoff stocker prices (new).

That was my first thought. Don't spend money to 'stay the same.' Whether subdued or raucous, improve the car in the process.
Damn pinko's in California aint gonna tell me what I can do with my truck!!! FREEDOM!!!!!!!

Small correction to your vernacular, if i may. To best describe your feelings in a healthy debate, i think 'commie pinko f%g' is more appropriate, with the gentle, but direct answer of 'because F$CK you, that why', if rollin' coal is your gig.

At this point, I would like to extend a formal invitation for you to join the Republic of Texas.

But only if he signs a binding contract agreeing to leave California in California 😂

Only if I get to dump Abbott and Cruz in the Gulf of Mexico.
Sooooo many things to say, but I don’t want Dad to close the thread ( ;) ), so I’ll just leave it at: they’re both establishment hacks, I could agree to that.
