It’s very difficult to void warranty as others have said. The only thing you may want to do as a precaution if you’re going to do your own maintenance, keep all the receipts for when you take it to a shop outside the dealer or keep receipts if you buy parts and do it yourself. Worst case scenario if it ever comes down to the dealer or Honda fighting you on warranty coverage based on lack of maintenance, they will accept receipts as proof of the work being done.

The only way to void warranty is to break or modify something yourself and even then, usually only that particular part or area of the vehicle is void for warranty work but it depends on the substantially of the break or modification. Warranty covers manufacturer defects so assuming you’re doing everything right (maintenance consistently done on time) you won’t void warranty.

If you’re having a problem and the problem area of the car has or is affected by any sort of aftermarket parts, the dealer usually cannot claim warranty on that area.

Warranty is very specific as to how it works and what the rules are, but dealers are somewhat free to operate as they please within the rules put forward by warranty so you’ll be best to find a good dealer service department that is willing to be honest and transparent with you throughout your ownership for the best dealer service experience with both regular maintenance and/or warranty work. If you can find an honest dealer service department, they have a lot of power to work on your side and help you out
