Brought my 2016 July built Model S in due to occasional blank displays. They ran the MCU auto diagnosis and found eMMC errors but won’t replace eMMC chip. Here is what they replied:
The eMMC was not replaced. It did not fail at all. This is what my technician wrote: "Could not verify customers concern. Preformed MCU auto diagnosis. Found maps missing. eMMC-related errors found together with map missing alert. The errors could come from navigation storage device instead of the Tegra eMMC. Vehicle showing maps up to date but a new maps is available. Both online and offline banks 0. Firmware is up to date develop/2020.36.11-155-ccacdb181f. Reset board cache, Reset maps, OTA maps .Customer to place car in good wifi, Customer to monitor."
I have them keep the car for the 3rd day to download maps which required 8-10 hours.
Is this typical that Tesla tech just keep finding excuses instead of fixing the problem and keep charging customers for the $195 diagnostic fees and wasting their time?
