Actually, copying data off a failed ECU is a BIG issue.
For those that have had MCU failures, this may be of interest. There's at least *some* possibility that the cars could be recalled for free (or reimbursed) replacements of the original eMMC chips. If you've replaced an MCU, you might be well-advised to add your complaints to the NHTSA database as they're only reporting 11 (!) complaints.
Mine hasn't failed, yet. Its showing all the signs (rebooting, laggy, audio tracks get stuck and skipping). I wonder if I could file one even though it hasn't officially failed yet? If enough complaints pile up, maybe we can force their hand on a recall.
This is not caused by an "electronics malfunction," this is caused by Tesla's excessive overwriting of the eMMC coupled with a cheap chipset. Tesla knows it, and anyone with electronics background knows it.
It's incredible to Tesla has doubled down on their incompetence by shortening the warranty to two years now.
I have contacted Hagens Berman, the law firm that handled the $5M AP1 lawsuit and have asked them to initiate lawsuit with me as the lead plaintiff. Anyone wanting to join in let me know.
Well I guess we'll see. This is a known problem and has been for quite a while and the NHTSA investigation adds further fuel to this fire. Regardless of the actual cause, the read/write cycles and the expected life of the chips IS, at the very least, a contributing factor. This is an integral part of the car that, in many cases, causes failure of the entire system. Tesla should have stepped up and fixed this and chose not to. This is almost a perfect example of why class action suits exist.No, we have a number of people working on replacing the chips that think a lot of the failures are the controller portion of the chip and not the flash memory failing from excessive writes. (There are likely multiple root causes.) It is entirely possible that there was a bad batch of chips in the 2015 time frame, which is why we are seeing so many of them failing now, where we haven't seen the same failure rate for older cars. They have also significantly reduced the volume of log writes which should make replacements last longer, assuming that they don't suffer a controller failure.
The warranty for the MCU that comes with the car hasn't changed. It is still 4-years/50k miles. The part, if you buy it out of warranty, used to come with a 1-year/12k mile warranty, then they upped it to a 4-year unlimited mile warranty, now they have dropped it to a 2-year/25k mile warranty. Still better than it was originally. (I think it better than the norm for the auto industry too.)
Good luck with that. If anything is going to happen it will likely because of the currently active NHTSA investigation.
Ok good luck. Pleas don’t inundate this thread trawling for plaintiffs. It is annoying.Well I guess we'll see.

Getting the MCU upgraded/replaced with MCU2 in a week or so in the 2015 S85D ....the unit definitely showing telltale signs of impending doom (flickering screen, spontaneous reboots, laggy browser); the service tech looked at the log and said it was like 90% done with life expectancy based on data files, etc. I have a Dell laptop that must be at least 12 years old that runs perfectly, but go know. Hope eventually TSLA steps up and corrects this issue for these early adopter cars.....
