I bought my 2016 Model X in Jan. 2020 and started having problems almost immediately with some memory functions. Took it in later (delayed due to covid) and they replaced the central body controller under warranty. I just had to take it back in because the touchscreen died and the car wouldn't charge. After all that, rather than replace the eMMc, they performed a "refresh." I was told that the part couldn't be replaced under the new warranty adjustment because the memory hadn't yet been "consumed." I said, "you mean yet." It is aggravating to no end that they are going to let this keep happening until it actually dies. It's unsafe--the mirrors wouldn't even unfold until I'd gotten halfway to the dealership; I couldn't use my backup camera, the car wouldn't charge so I had to drop it off 4 days early. So far this seems like a joke. I still haven't even picked my car up yet and they won't just replace the part that is clearly A) causing the problem and B) covered under this program.
