As far as the 'eaches' goes for returning a can't-be-fixed computer, the OP is out of luck.
However, if there is a systemic issue, the firm is liable.
Some years ago, around late 90's, early 00's, Uwatec's TEC or Z Computer (IIRC) had an algorithm issue in that once you set the Nitrox level, the algorithm assumed you continued to breath that same Nitrox level during you surface interval.
A few divers (about a dozen, again, IIRC) got bent because they dove aggressively and were back in the water to dive deep again to the second.
Uwatec recalled the computers and issued new ones. The management left or was fired, because the engineers reported the problem and the management just said, "Meh."
Just like why the Challenger blew up.
