Decal Problem

^This.
Otherwise, in general, vinyl decals suck over the long haul. Great for selling rigs, don't last in the sun.
If going for warranty isn't an option, honestly, I'd use some elmers glue or rubber cement, in the shade. Get it applied, immediately squeegee out the excess and clean up the mess right away.
Never done this myself as peeling decals are typically old and brittle.

With such a new rig I'd be calling the manufacturer for replacements. I know decals peel and disintegrate over time but during the first year isn't a good sign for the rest covering your rig.

Your best to remove them and start over. Call the factory about replacements if you like the look.
