I imagine they were making a nice profit forcint people to pay $2000 for a reman mcu1
Many people here have a view point as though they were standing at a large construction site peeping in to the building area through one little observation hole in the wall protecting the bystanders. They see one thing alone. They don't know the effort that came before and they only see a narrow field of view. Its easy to bash Tesla at any given point and ignore any changes they are making.
As recent as winter of '18 and early spring of 2019, the cost to replace MCU1 was $4,000. Tesla was no longer putting MCU1 in new cars, so what was "on the shelf" was dwindling with no re-replenish coming. nVidia was no longer making the Tegra boards that were customized for Teslas either. So Tesla was not making new ones. Owners with out of warranty cars paid $4,000 to get their car fixed. Its in posts on TM and TMC, if you look. Tesla had no process for re-manufacturing used parts. There were no cores, there were no re-manufactured units Anyone with a problem paid for a brand new MCUs. They started keeping the old ones and found a way to refurbish them. In just a few months Tesla had a small supply of re-manufactured stock as the supply of new MCU1 decreased.
There still was no increase in new units, as they re-manufactured old ones. The price of re-manufactured units was ranging from $2400--$2700. (My guess is they were proud to have found a re-manufacture source and got a contract up and running in a few months. They brought the price of getting a car back on the road down from $4,000 to $2400-$2700.) The demand was growing as more failed with more active time on the MCUs. Cars were coming out of warranty so owners were paying more often. Yet in Feb 2020, Tesla had managed to bring the cost of swapping out a MCU at the SC down to $1300. (Probably leveraged their position to negotiate a better price.) For roughly the last four-five months, there's been more reports of failed MCUs going in to their SCs. And there's been such a shortage that people are waiting 4-8 weeks for a repair. I'm going to say that again for the hater's - the price on re-manufactured MCU1 came down from $2400 to $1300. They didn't have to find a way to do that. They could have just keep the extra money and not saved anyone a nickel. In a few more months MCU2 started becoming a common upgrade items and grow the MCU1 stock. But instead of keeping the re-man MCU1 high, they brought the price down.
Now we have new MCU2 going into cars removing MCU1s. Tesla keeps the core unless the owner demands it then they pay the core charge, as other manufacturers often require. The MCU1's going back to Tesla will help with the quantity available. I believe MCU2 will soon be available for '15 AP1 and older cars. Good.
But Tesla doesn't defend itself and remind people of how they are improving their own processes. Slow? Not fast enough for you? Sorry, that's the way it is. But better than nothing.
I applaud their efforts. 45 years ago, I used to work in the dealership and jobber parts business. Tesla moves at lightning speed compared to most.
