unkel wrote: » The issue we are talking about here - a very common issue on older Tesla Model S - is the flash memory chip failing because it simply has been written to too many times. The part was not fit for purpose because the software excessively wrote to it and these memory chips can only take so many writes before they are likely to fail. Part is being replaced (free of charge) with a better part and the software was long since changed to no longer log data as excessively. Problem sorted. Not a big deal.

That said, it must be in exceptional cases only, never heard of that before and any MCU1 failures typically give signs / artifacts / freezes etc. for several months before a serious failure happens. Plenty of time to get it fixed Anyway storm in a tea cup, free fix by Tesla and the problem will never happen again (as there is no longer excessive data logging on a memory card too small that can't handle it) Big problem is the few people that paid big bucks to Tesla to have this fixed. They should be compensated. If I were one of them, I'd go get my money back.

unkel wrote: » I doubt some of the stuff he is saying. I can't see a single cell failing having any impact on the overall battery or render the car grounded. The bricks are something like 6S80P so if one parallel cell fails, the voltage stays the same and the capacity just drops by a bit over 1%. No big deal. If it shorts, it is fuse wired, so doesn't impact the rest of the battery Also $5k is insane for that repair. What you do is remove the battery, test each brick, locate the faulty one and replace it with a second hand one (they cost about $1k each). Labour maybe $200-$300 for that and you keep the faulty brick. Either sell it on for a couple hundred or fix it and use in the above repair. So more of a $1250 job than a $5000 job:

unkel wrote: » Not quite correct. Tesla take out your whole battery pack and replace it with a refurbished pack. That's these days, in the past you might have got a brand new pack. We don't know yet how much Tesla will start charging for this job when the warranty is up, as all battery pack replacements worldwide so far have been done for free under warranty But I think it is reasonable to assume that if they charge too much, independents will pick up on this and offer a battery fix for much less money (that's exactly what happened when Tesla charged $3k to fix the MCU1 problem).
