Tesla has agreed to replace the MCU1 in my CPO 2015 S 85D, which is excellent. But they've been trying since about April to get the part, to no avail. I've been getting weekly email updates that indicate the part is outstanding, with a ship date "pending". Anybody else getting MCU1 warranty replacements in a timely manner? The car is drivable, but fairly annoying due to the quirks.
