That's not the fault of the subs, it's the sleep deprived and overworked crews, and inexperienced and also sleep deprived officers manning them. Our ICBMs will work perfectly when they are accidentally launched.
Or it may be because the military has shrewdly shifted their priority from operational capability to ensuring peoples' feelings don't get hurt.
Maybe the technology will work a little too perfectly so the generals will helpfully circumvent the civilian government and phone their friends in the CCP to warn them ahead of time so they won't feel offended.
