There's only two things that might cause one car to turtle at 350V and another to turtle at 290V.
1. A software problem. No further explanation needed here.
2. At least one cell-pair with significantly lower capacity than the rest - one cell-pair hit the low-voltage limit and the BMS shut the party down. Should be easy to check with a Consult by taking this car down near turtle.

If we know the voltage at which a battery with all good cell pairs goes to turtle, then anyone with Gary's SOCmeter can run to turtle and check pack voltage. If it's significantly higher than normal, you have one or more bad cell pairs, which would be a warranty issue.
Or that the pack is out of balance. Need to charge and not drive right away, at least occasionally.
