Tesla has a fix for the Roadster 80A charging bug. This will enable Roadsters to charge from unmodified Clipper Creek CS-100 charging stations. The Roadster is still limited to 70A charging, as increasing that limit would presumably require hardware upgrades. Update January 16, 2014 The firmware update is now available. Yesterday, I got the update and a car wash at no charge for our out-of-warranty v1.5 Roadster. The details from Danny at the Seattle service center are: v1.5 firmware is 3.6.12 and is just the 80A fix. v2.x firmware is 4.6.8 which fixes the 80A bug and allows shifting from drive to reverse at up to 5 mph dsm363 confirmed the 80A fix on a 2.x Roadster. I've confirmed the 80A fix on a v1.5 Roadster.
