Vehicle Details

"For sale: 2013 Tesla Model S P85 with 105k miles. Enjoy complimentary supercharging and premium connectivity for the life of the vehicle. Recently underwent an infotainment upgrade from Tegra MCU to Intel MCU, accompanied by a retrofit MCU jumper harness for improved functionality and firmware updates. Seeking a buyer with Tesla experience. This generation 1 model is out of warranty. Note: there is an issue with the contactors not contacting, causing a drain on the low voltage battery (12v). To prevent battery depletion, it's disconnected overnight. While the car remains drivable, I lack the expertise to diagnose and repair the issue.
