1. Unexpected car breakdown after reaching a milestone with the Tesla Model 3.
2. Issues with charging the car and receiving error messages related to the charge port and 12-volt battery.
3. Car required a repair for the Fast Charge Contactor assembly for the High Voltage Battery.
The author recently wrote a review of their Tesla Model 3 reaching 100,000 miles, highlighting its Total Cost of Ownership. However, after writing the review, the car experienced an issue with the fast charge contactor assembly for the High Voltage Battery, leading to a breakdown and confusion with error messages. Despite communication via the Tesla app, the author had to wait a week for the car to be repaired.
It was speculated that the car’s 12-volt battery would continuously try to charge due to the seized up fast charge contactor, draining the battery. The repair cost DKK 3,480, raising questions about the initial “12 volt battery needs replacement” message. The author theorized that the contactor issue may have been caused by wear, moisture, or low voltage coil failure.
This incident serves as a reminder that EVs can experience breakdowns too, with error messages sometimes indicating a different underlying issue. The author emphasized that the incident may be of interest to all EV owners, highlighting the importance of understanding potential points of failure in electric vehicles.
