In the end the firmware updates didn't resolve my 32 amp charging limit and Tesla Engineering diagnosed mine as needing a new PCS and HV PCS Fuse. Back from service and charging at 48 amps again! They did say the vast majority of these cases were resolved via firmware however.

2020.36.15, and later .16 did not resolve the AC charge limit of 32 amps for me. Tesla Engineering diagnosed my particular case as requiring a new PCS. They did say >99% were of these were firmware related though. Car is back from service with new PCS and PCS Fuse - now charging at 48 amps again!

Car back from service. New PCS (ASY, PCS, 1PH, MDL3) and replaced HV Battery Power Conversion System Fuse. Charging perfectly again at 48 Amps!

Neither 2020.36.15 or 2020.36.16 fixed my 32 amp charge limit on my RWD LR M3. Tesla Engineering has now diagnosed my situation as h/w and scheduled me for a PCS replacement. So in my case it was determined to be a h/w problem that was being masked for a while by the known firmware bug. The...

Perhaps it is the PCS. Mobile Service came out today (because I had a low tone horn that needed replacement). The tech. re-pushed 2020.26.15 again ahead of his arrival - but still wouldn't charge over 32 amps. Tried to send 2020.40.3 but wasn't available yet for my car. Since so many cars...

Firmware 2020.36.15 did not resolve my charging problem. Still limited to 32 amps on a 2018 LR RWD model 3 and getting the Charge Rate Reduced notification consistently every day both at home and at 4 other public chargers I have tried. I’m glad for all those that the firmware update has...

Is anyone with firmware 2020.36.15 had their charging problems fixed? I got 36.15 two days ago and still cannot charge over 32 amps, but I've seen a couple reports saying it fixed the issues for some people.

My 2018 model 3 RWD LR was updated to 2020.36.15 yesterday. Still won’t charge over 32 amps. I tried to schedule service earlier with Mobile and Service Center and both said wait for a firmware fix. Unfortunately this firmware did not fix my issue. I may try driving over to another town...

Same. Had my appointment cancelled stating this is a firmware bug. I even stopped by my local Service Center - who had a technician check the logs - same conclusion. No ETA on when the firmware will be available, but this is the reply I got from mobile service. "We have spoken to engineering...

Thanks - That is great info. I dropped by my local SC today as well and the tech. pulled logs and investigated. I also provided the case # for the chat I had with Tesla Home Charging. The conclusion was the same - that the issue is firmware and we must wait for a fix. I wasn't able to get as...

Update: Tesla mobile service reviewed the Case# and is confident this is still a firmware bug that will be fixed with a new push. The inability to charge at 120 V on the mobile connector was just a scheduled timing issue - now charging fine on Level 1 120V with 2 different chargers. So must...

Update: I ended up calling Tesla Home Charging support (just follow the options from the main Tesla phone #). It took 90 min on hold but I got connected to a very helpful knowledgeable home charging specialist. He was able to remote to the car, see the detailed logs, and even call up a month...

Just happened to me also. LR RWD 2018. I get the "Charge Rate reduced" for anything over 32 amps. Local Service centre replied with: "We have spoken to engineering and they have determined the issue that is occurring with charging is related to a known firmware bug. They are diligently...
