NHTSA complaint #11670914

Owner complaint summary

My 2020 Tesla Model Y Long Range/AWD vehicle has 46,000 miles and can no longer recharge its battery (engine) with an approved charger (L2) due to a commonly failed part inside the battery. This part is called PCS (Power Conversion System). This device attached to the Tesla battery is used to convert power from a charger which is AC (household alternating current) into DC (Direct Current) the battery can understand. This error appeared for the first time on [XXX] at [XXX]. This critical part has failed in thousands of Tesla vehicles, some multiple times easily verified by thousands of customer complaints online. The PCS is NOT a consumable part - such as a tire, wiper blades, brake pads, etc. There is nothing the vehicle Owner can do to prevent the PCS failure. The Cost to repair/replace the PCS part(s) is ~ $3,000 and may fail again after replacement. As required by Tesla, I scheduled a service appointment through their phone app, and received an estimate of ~$280.00 to repair my vehicle on June 26, 2025 at the Irvine, CA Tesla Service Center 2801 Barranca Pkwy. After diagnosis, I was informed the cost to fix/repair the PCS part in my vehicle so that I could charge and drive it, would be ~$3,000. The Manager Ryan Sutherland (949) 404-2989, further stated the repair would not be covered under my Vehicle Tesla Warranty (Tesla battery or drive unit warranty that does not expire until [XXX]). I tried to contact Tesla corporate for assistance at resolutions@tesla.com and did not receive a response but instead was contacted by service manager Ryan Sutherland via email confirming Tesla's warranty position. Tesla is essentially the only service/repair resource available for these vehicles. This repair is obviously due to a faulty/defective PCS or faulty design by Tesla affecting thousands of vehicles and should covered under my vehicle warranty so that it can be driven.
