If you own a Tesla you know that charging is a critical part of charging… No charge and you are not going anywhere.

With a Tesla Model 3 one of the first Model 3 releases some of the systems may have been questionable in their design.

Being able to charge whether it be at home or on the road is critical, being able to charge using 110, 220 is critical to EV’s.

For some reason Tesla has stated that the Power Conversion System is not covered under the battery warranty, although it is a critical component of the battery.

Having done the majority of charging using Tesla Supercharging may have impacted the PCS failures.

The other issue is that the PCS failures appear as messages that basically make no sense.

The PCS is composed of three models that are 16amps each, when one fails your ability to use AC charging drops from 48amps to 32amps, when two fail you charge max is 16amps. Which is where we are at.

It’s been quite sometime since we noticed the cryptic messages displayed on the app stating that there is a grid issue or that the wiring in our home is not supporting the charging at over 16amps. I finally had enough and not only took our car to a neighbor who has a Tesla charger and experienced the same issue, then had an electrician come out and confirm that our wiring is good, that we should have no problem charging at 48amps.

Extremely concerned I opened a service request with Tesla. They have quoted a repair estimate of over $2600!  Yes $2600 to repair something that is critical to the charging of our Tesla.

I would think that Tesla having run a variety of diagnostics and upgrading our original HW 2.5 to HW 3 would have detected these issues and advised that there was a failure, but there was no mention.  And these warning with charging limitations have been present for a very long time. Even before the HW 3 upgrade. So I estimate that the vehicle was most like still under the mfg warranty at the time.

Regardless the vehicle has less than 50,000 miles and a critical charging component has failed.

Supposedly there is a Technical Service Bulletin
