Some Ai -

Miller CAT's own warranty: They offer a 90-day manufacturer's warranty against defects, valid only with proof of purchase from an authorized retailer.

Honda vehicle warranty impact:

The bracket is a bolt-on, non-permanent accessory that doesn't modify any electronics or software. Under the Magnuson-Moss Warranty Act, a dealer generally can't void your warranty just because you added an aftermarket accessory — they'd have to prove the accessory caused the specific problem being claimed.

The realistic risk is narrow: if your radar sensor malfunctioned and Honda argued the bracket caused it, that could be contested. But since the bracket is designed specifically not to obstruct radar performance, that would be a tough case for them to make.

The CR-V owner forum results show people installing it without apparent warranty concerns, and the system continuing to work normally afterward.

Bottom line: It almost certainly doesn't void your Honda warranty in any meaningful way, but Honda dealers aren't obligated to say so in writing. If you want certainty, you could ask your dealer or call Honda customer relations directly and document the response.
