its very subjective bro, whatever you touch on ur car the SC can void ur warranty even sport rim they will void ur absorber warranty(example) its depends on SC at the end.

Solution not to void warranty;
As my Myvi just gotten not more than 3week~ its also under warranty, what u guys do is before u claim any warranty just plug it off the TAB and plug back the original hose direct back the place it was and its done. No problem occur then ^^ happy using with TAB ya
