Consumer Description

The 2017 Tesla Model S we purchased has a known issue with the MCU. The MCU rewrites information in a log chip repeatedly and has been known to burn itself out after short periods of time. Tesla has agreed to replace the MCU owners when it malfunctions, but they will only do so when the chip has completely destroyed itself and will no longer boot. Ours was malfunctioning every ~40 mins...all of our screens would black out while driving. Tesla refused to replace it. Additionally, we purchased Full Self Driving from Tesla with a contract that stated "all needed equipment and software included." This was not a true statement. Those of us with the malfunctioning MCU1 were not included in the FSD program and were forced to bribe Tesla with $2500 to update our MCUs even when they were under warranty and should have been included under the FSD contract.
