Do upgrades void the warranty?

[Erik The Red]

I assume the answer here is yes. But, would installing after-market parts void the warranty? Such as performance suspensions or does it only void the warranty on that particular subsystem?

Only if the upgraded part could realistically alter the affected part. Look up the

Magnuson-Moss Warranty Act​

Also the dealer has the burden of proof that said part did in fact cause an issue with the rest of the cars systems and parts.

this is also available in Europe? I'm thinking to upgrade my coils for a softer ride, but I'm afraid of warranty void.
