Nah real problem, especially on smaller cells like 18650 back of the day is balance or temperature cable welds that randomly pop off, rendering entire pack useless and very laborious to repair. Rest of the things are very rare. If you crash hard enough to damage battery usually entire car is written off.

I've been looking for used Tesla in Eastern Europe. Battery repairs are so rare (I think I found 2). Post-crash rebuilds are basically 95% of cars sold here. 100% if car is from USA.
