Power Conversion System (PCS) failure
There are a few threads going here and on other forums for charging issues that turn out to be PCS failures. Most owners notice the failure when they are AC charging (Wall Charger or Mobile Connector). The charge rate will drop from 48A to 32A or 32A to 16A and give an error message saying...

You should have traded-in with a newer one once the warranty ended.
The newer M3 look the same, but they are very very different cars.

I have a 2018 LR AWD (at my primary house) and a 2023 standard RWD (at a bother home that we use 2-3 months a year and Airbnb the rest of the time.
I like my 2018 way more than the 2023. Not being able to adjust regen to low sucks in the cold. The heat pump sucks in the cold, the battery uses a lot more energy to “condition” itself in the cold, I greatly prefer the manual trunk to the electric opening one. The only improvement for me is range and that the 2024 has a steering wheel heater.
That said I live with the 2023 but my 2018 is here with me in Alaska. There is no way I’d buy or keep the newer model here as it is much colder for longer than where my other place is.

Thank you kindly linking it! rather than making me search for it. My car was build around that time per TSB July, 2018. So far charging at 48A using Wall Charger been okay, but now i know if something happens. Really appreciate it.

It is XCare EV Protection.
In my opinion (very debatable) - it is better to set certain $ (roughly cost of warranty) aside in High Yield Saving/SP500/Bonds/Mutual funds to gain money over time and if you ever end up needing it, you will have the $ to cover it. At least that is what i used to do with my ICE car. But with EV, there are less parts? and therefore can make repairs considerably more expensive.
For example, lets say it would be $4,000 for coverage over 4/5 years. Very hypothetically if you were to invest that money and you gain 10% YoY (very high return if stock market is doing well), then in 5 years you will have $6500 in your pocket. Is it worth the gamble to see if your repairs will be less than $6.5K over 5 years? need to search for high mileage Model 3s to check it out. This is just for reference, there is no need to argue about return rates, where to put money, etc.

Oh nice. Tesla only allows warranty if car' basic one did not expire. Those cars from 2018 did expire, therefore at least for now, Tesla is not an option sadly.
We @ XCare do know these vehicles are cheap to maintain but can be costly to fix... so thats where we come in! Check out our website for more info and a quote for your Model 3 @RSpanner . Let us know how we can help! www.evwarranty.com

Gotta say, I’m slightly concerned about this as well.
I’m just shy of 150,000km on my 2018 Model 3 performance.
In the last 6 months, I’ve had to deal with several issues.
- Had a restraint error and had to replace the center seat buckle in the rear seat.
Drivers seat occupancy sensor became faulty so the car and climate controls stayed on and the car wouldn’t auto lock.
12V battery replacement (my first)
A few of the wishbones/suspension linkages in the rear needed replacement, so I replaced all of them with mountain pass performance aftermarket pieces.
Front and rear windscreens both cracked spontaneously. This is by far the worst and most expensive issue I’ve had. Is the glass faulty in these cars or what?????
Finally when I was last at the service center, they said I needed to replace my front brake pads and rotors. I’m planning on doing it shortly, will definitely snag an aftermarket performance upgrade for those as well.
I’m so sick of seeing all the shareholders on Twitter claiming how reliable and low maintenance their cars are…. “All I have to do is put washer fluid and tires on it and I have 200,000km on my car…”. Yeah right.

ouch. I wonder how much of this is performance issues? Also I wouldn't count the 12 V battery since that's a low $ cost and not unique to Model 3
I did get the extended warranty. My 1st on a car.

The 12V wasn’t cheap in my case. I decided to get an aftermarket lithium battery. . Saved 17lbs though, and my hope is that it might last longer.
