NHTSA Complaint #11437904 — 2018 TESLA MODEL 3

Power Conversion System was defective when car brand new and replaced under 50k mile warranty. Now out of 50k mile warranty and Power Conversion System is failing again. Manufacturer service center says this item is customer pay and is just a defective item that is out of warranty for the 1-year replacement warranty, and refuses to cover this repair under the battery warranty where the Power Conversion System is located. Service center states there is nothing the customer did wrong or could do to cause this problem, acknowleges it is a defective part, and insists it is customer pay with no indication of an updated part. What happens when the Power Conversion System fails is the car is stranded and cannot recharge or operate its safety systems. This should be a recall item if it was updated to a newer part correcting defective design. The manufacturer should replace this high voltage and core functionality of the vehicle under its battery warranty where the part is located. It would be highly dangerous for the vehicle owner to replace this part and requires specialist tools to diagnose and replace or repair.
