So, on delivery one of my door handles needed to be replaced. That was back in 2013. Within a few months, another went. Replaced under warranty.
Over the past month, another one bites the dust. This time, no warranty. $400. Even just stopping there, the fuel efficiency gains of a retracting door handle over the lifetime of the vehicle are wiped out.
But get this... the door handle replacement required an MCU replacement. Yes, you read that right.
Because of Tesla's widely documented MCU design flaw that chews through SD cards with excessive logging, my MCU stopped accepting firmware updates back in 2017. No big deal to me, really, I bought a car, not an arcade machine. So I didn't really care about running pac-man or space invaders on my car. I just wanted something I could drive.
Unfortunately, that's not where it ends. It turns out, the MCU needs to "accept" a number of other items in the vehicle -- including door handles.
BTW, this also extends to drive units. So while our drive unit is still under warranty and has failed (for the second time), we can replace that but not without replacing the MCU first.
FWIW, back in 2016 I was told that the issue with MCU freezing was due to "NAV locations and trip metes (sic) were taking up a lot of memory." This was quite the foreshadowing for the flash issues. But even back then, I (practicing computer engineer) thought to myself, what kind of grade school drop-out amateur engineer develops a system that runs out of memory updating the trip meter and recent NAV locations?
Out-of-warranty ownership of this vehicle is going to be expensive!!
