i recently just purchased a used 2013 g37 journey with 66k on and the dealer gave me a 200k power train warranty so anything goes wrong with anything power train up to 266k they will replace for as long as i dont break warranty and keep up with regular maintenance. i do not know how long i plan on the keeping the car but i would like to modify it but also dont want to break the warranty didnt know how reliable the trans and stuff were. what do you guys think?

 

Replace the wheels, cat-back and sway bars... no warranty issues there. They might bark at you if you replace the cats, use an aftermarket intake, or if you drop the car and change the suspension geometry. They shouldn't because that's silly, but they might. Depends on the management team at that dealership, and even then you could challenge them if need be.

What are you thinking of that might compromise your warranty?

 

anything engine wise would probably do it idk i can call and ask but i know the sales person was talking about how people have put intake's and it voided it lift kits on trucks etc. like you said tho pretty much the only main things would be exhaust and intake and maybe the sway bars and just little cosmetic things. i know i can give them a call and ask if certain things will void but i dont plan on doing anything for probably a couple of months if i do end up doing anything just depending cause it would be nice to be able to fall back on the warranty if anything ever did go wrong i couldn't imagine what a 7 speed auto would cost lol

 

If you do anything that you may be wary of regarding warranty work, be sure to keep the OEM parts in case you have to get it back to stock form.
