| Engine And Engine Cooling problems |
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.
