NHTSA Complaint #11712551 — 2013 TESLA MODEL S

While charging my 2013 Tesla Model S, the vehicle experienced a charging system failure and would no longer charge. Upon inspection, I discovered water intrusion and corrosion on the lower portion of the charging-related electronic circuit board at the bottom of the charging port and right where the High Voltage cables are located as well. The affected electronics are located in an area that is not normally exposed to water and is not owner-serviceable. Later model Tesla Model S vehicles (2014 and newer) include a drain in this exact location, which this vehicle does not have. This design change appears to directly address the same water accumulation issue that caused the failure in my vehicle. The failure results in loss of the vehicle’s ability to charge, rendering the vehicle inoperable. Tesla declined to repair the issue, stating the vehicle is out of warranty, despite acknowledging the design change in later models. This appears to be a latent design issue related to water ingress into critical charging electronics, which presents a safety and reliability concern due to loss of propulsion capability and water exposure to High Voltage parts.
