unfortunately those engine mods definitely void your warranty and likely are the cause of your problems...

Remove them and bring your car to a different dealer and you should be able to get service under warranty....

 

that is not correct. Nothing can automatically "void" your warranty. The dealership must prove the mod was the cause of the problem before they can deny it as a warranty claim.
Stand your ground

 

That is technically true... however a plenum spacer with a faulty gasket could easily be blamed for the problem. And it depends on the dealership, but there is a magnuson law that protects you... just as brocken states...

however, if they can even find a reason (the improperly installed mod or the act of installation caused the failure) other than an actual failure of a factory part, they can go back and charge you for everything from diagnostics to breaking the engine apart to replacing it....


Honestly, do you think your mod may be the culprit? If there's a chance it might be... then the above statement can go into effect... If it was me I wouldn't risk it and return my car to stock engine and then have them trouble shoot it... you could always put the mods back again afterwards....

btw I'm only talking about the plenum spacer.. the air intake rarely voids warranty unless it was leaking and allowed unfiltered air into the engine...

my 2 cents..

 

well, called the dealership on friday, they told me that they had most of the problems fixed? I was told my car would be ready by friday, but come saturday and still no response from dealership...i will call them again on monday.

 

What were the problems that they fixed?

 

ok.. got the car back today, had to pay 215 dollars for them to check the engine. here is what they wrote..
"found codes for multiple misfire. test drove and verified misfire. found intake spacer bolts loose and intake repositioned. retorqed all upper intake bolts cleared codes and test drive was ok"
well, i got the problem as soon as i was on my way home. called them and i am sure now that they have no idea what they are doing... im kind of pissed.. and dont know what else to do, i will take it in again tomorrow and see what they say...
grrr...

 

remove your mods and take it to another dealer.

 

I agree.. Dont take it back there. Take it to Advantage nissan in bremerton, TRUST ME, its worth the drive. Enterprise is right next door, and they might be able to get you in a rental.
