I saw some threads about this. I have my car in for service and they indicate that I can't charge over 32 amps with the RWD. However, I know for sure it used to charge at a higher rate. Did they update the software to limit to 32? This seems insane.

2018 Model 3 LR RWD Charging limited to 32 amps?

Since you have the LR, it should charge at 48a. They are making a mistake because currently, they sell no RWD cars with the large battery and 48a charging. However, in 2018/19, they did.
It might help if you referred to your car as an LR instead of as a RWD.

You likely have a failed module in your power conversion system (PCS).
(moderator note)
Thread title amended to add "LR" so that it correctly reads "LR RWD", as that is a configuration of the car that is no longer sold but that exists, as pointed out.

Tesla telling you that "RWD cars can only charge up to 32amp speeds" is unfortunate, especially if it was in for service at the time. That means whomever told you that (on the tesla side) was simply "going off what they knew".
I mean, I sort of get it, because I am sure they get "hey why is the wall connector only charging at 32amp on my RWD tesla model 3?" as a question only slightly less than they get "how come I drove 7 miles and 10 rolled off my battery meter????????????", but that still doesnt excuse them not checking to verify what they were telling you before they told it to you.

A 2018 LR RWD (like mine) will charge at up to 48 amps regardless of what others say. Mine does. Yours should too.

I have a 2018 LR RWD Model 3. Just bought the Tesla Wall charger. Car will not charge past 32amps. Why?
- If you're using the mobile charger, even on a 14-50 plug that is limited to delivering 32A. (car displays 32/32A)
- The wall charger you're using might limit power to 32A (car displays 32/32A)
- One of your onboard charger modules could be bad. Since each of the three modules handles 16A each, you'd only charge a 32 instead of 48A.
EDIT: I just saw (re-reading) you bought the Tesla wall charger. Assuming this is a Gen3 (latest), you need to configure it through its wifi connection otherwise it defaults to something low.

Either the wall connector you're attached to is limited to 32a as suggested above, or your car's on-board charger has a fault. When charging, on the main screen you should see two amperage numbers separated by a slash like 32a/32a or 32a/48a, etc... The first number is the number of amps you're charging at, the second is what the wall connector is reporting as max. If you tell us what your car says we can tell which situation you're in.

Unless they recently changed it, it actually defaults to a 60 A circuit.
Everything else was spot-on.
LR RWD here. We can hit 48a via Tesla home charging station. It’s nice! I charge at 32a at home via mobile chargers.

Yeah, same here. 2018 LR RWD charges as fast as a Dual Motor, 32 amps on the mobile connector and 48 on a destination or home charger.
