Consumer Description

While charging Model 3 the amperage went from 32amps and was capped at 16amps. This is a wide spread issue with Tesla’s model 3 Power conversion system (PCS). There is 3 controllers in the PCS system. When all 3 are working correctly it will charge at 48amps. If one stops it will drop to 32 amps or drop to 16 amps if two fail or not even charge if 3 fail. This is a known issue and and costly repair as Tesla refuses to fix these under the battery warranty.
