Does adding rims and window tint void any warranty?

Keeping Your Mod's Warranty Intact - For Dummies

Pls take no offense to the "dummies" part but this actually breaks down in detail what you are asking

 

You live in the US, so the the Magnuson-Moss Warranty Act applies. It prohibits manufacturers from denying warranty claims from aftermarket parts unless the manufacturer can prove the aftermarket part damaged the part you are making the claim on.

See the paragraph Will using 'aftermarket' or recycled parts void my warranty?

 

Window tint is legal or illegal under state law, you will want to understand the state law of every state you drive in.

Tint Laws

 

Many dealers have a tinting service they partner with should you request tinted windows. Jimbopalmer makes a point that some tint may be illegal. But Illegal or not, it will not affect your warranty.
I just had my windows tinted and went through the dealer I bought my car from. They give the local tinting facility so much business and receive a mass discount that I actually had it done cheaper than I could have by shopping around on my own.
I have the same wagon as you do and had it done for $170. The lowest other shops would go was starting at $190 and as high as $250.

 

well if for example the window motor broke, the dealer may pin it on an installer that had to take the trim apart to access the window and then fried a wire or something. Same with rear defroster, i've seen some poor tint jobs mess that up. Otherwise you should be good on tint. As for rims, if they are same size/offset you should be okay but different offset or size may effect suspension (most of that is considered wear and tear and not under warranty anyways)

 

No warranty problem in CA.
Any issues that arise while under the original manufacturers new-car warranty are burdened by the manufacturer; who might presumably argue that your "add-on" product somehow caused the warrantied auto, or its parts to fail.
Wheel upgrades and window tint won't muster such argument. Both items are often offered by your F&I closer. So....it's not like you're modifying an engine or drive train...
