dealer closed today so have a question

Cv joint on front left started taking a shit a few weeks ago…factory clamp came off outter axle side of boot. Clamp still intact but it slide off boot and obviously compromised joint. Put a hose clamp on for now to milk the joint a lil longer since i dont get time to ride much…just clicked 400miles in 14months of ownership.

Last fri rode for 27 miles at new to us park. Finally got time to clean up both machines and seen something spinning on right rear outter cv boot….this time a clamp popped off the right rear diff cv boot that attaches to axle….wtf.

Is this a common problem having these cv boot clamps pop/slide off?
Is any of this covered by the extended warranty…pisses me off to buy $200 in half shafts over 2 $0.10 clamps somebody didnt cinch down…and now im wondering if the other two axles will succomb to this also…may e a bad batch from china and a pissed off worker with no phucks given the day he got the clamp job?

Just asking until i can talk to dealer tomorrow for a definative answer
