Can you Modify a Car without Voiding its Warranty?

"The simple answer is: it depends. Modifying a vehicle can make it more difficult to maintain warranty coverage, though the Magnuson-Moss Warranty Act puts the burden on the automaker to prove that a modification directly contributed to the failure of a specific component.

What a dealership and an automaker cannot do, according to the Magnuson-Moss Warranty Act, is void a warranty simply because a modification is present."

This is true, and there are significant fines involved to motivate manufacturer compliance. On the other hand, if a manufacturer refuses a warranty claim based on a modification you've made you're only recourse is the courts, which may cost more than just paying the cost for whatever repair is needed.

The bottom line is there is ALWAYS some risk when you make a modification to your vehicle. This is especially true for modern vehicles micromanaged by computers. It's simply not possible to fully understand how any given modification will affect the various systems throughout the car.

My points, in a different way of putting it. It boils down to...do you want to fight it? How far are you willing to go? Paying a lawyer? In the mean time, your vehicle is at the dealership waiting on a warranty approval while you plead your case.

OP needs full explanation why fuse no.3 is unusable for this application
would schedule service mgr and tech both for meeting to discuss matter
check manual for amp draw on the sound system relay
make sure the tap was positioned correctly (not installed backwards)
if tap is installed backwards the device will operate unprotected
unprotected it will draw as much current as wiring and device allow
lastly do not leave without finding out which fuse is acceptable for this tap

And For anyone wondering, the bottom of #3 fuse slot is the 12v side

Been using no. 3 for footwell lighting no issues with anything. Only very unlikely way I see it could be an issue is if somehow voltage could transfer back through remote wire. But even then it's fused anyways.
