thanks in advance
John Harden said:No. Don't confuse voided warranty with being denied warranty coverage on certain parts. On anything aftermarket, Nissan (through your dealer) might deny warranty coverage if they can prove that your mods directly resulted in failure of the warrantied parts.
Easy example:
You replace your factory brake pads and rotors with aftermarket ones you bought off E-bay = Nissan no longer has to honor their warranty on brake pads and rotors. Why should they? You removed their factory parts.
Less easy example:
You remove factory amp for stereo and replace with higher quality amp of same wattage. You wire it in correctly. Weeks later, stereo goes up in smoke. Is it your fault, or a problem related to stock unit? You'll have to argue this one with Nissan and dealer.
Tough example:
You lift truck and replace stock rims and tires with 18's and mondo, 37" tires. Drive train shows wear, front brakes show wear and rear diff blows. Dealer may claim that more weight on drive train caused failures. Most dealers won't argue this too much, but if they do, you may have a long road ahead.
Last two aren't all that different except for cost. Drive train and brakes cost a lot more than does a cheap, factory stereo.
