Not really, Your pack has a few percent less capacity than others comparable. 4% I believe from other's calculations. I don't personally believe that makes it faulty, but that is not my determination, or any other owner to make.
If your battery is truly defective, it will continue to degrade rapidly. When your range loss puts you out of the norm from other owners, then I believe your argument will be received and acted upon. Drive your car and see what happens. If you stabilize at your current range, enjoy it for what it gives you.
Degradation curves for these batteries has always been ~3% the first year, then 1% for every year following. YMMV !!! Charging to 100% and leaving it there will cost you in this curve. I don't believe it is just the number of range charges that is detrimental, but also the time that the battery sits at 100% SOC.
I personally don't charge to 100 % very often, and when I do, I time my charge so I can leave within 1/2 hour or so of the charge finishing!
