Charging Not Exceeding 24A - Troubleshooting recs?

[Texarado]

My house has a gen 1 wall charger. It has always charged at 40A, but now, when I plug the truck in to charge, I’m limited to 24A. It will not let me increase beyond that. Has this happened to anyone else and do you have any recommended troubleshooting steps?

Also, I checked my Model 3 and it’s not having any issues at all. Still charging at 40A. My truck is running on 2025.26.8.

I had the same issue with my truck a few months ago. I took it into service and they had to replace the power conversion system.

Definitely take yours in for an inspection.

Did supercharging work at a higher rate? I haven’t tested it out at a DC charger yet.

I didn’t test on a supercharger but tested various L2 chargers. Wouldn’t go past 24A so that’s when I made the appointment with the service center.

Schedule a service appointment

Supercharging should not be impacted.
There are two AC/DC conversion modules, each does 24A to get to 48A . If one dies, then you're limited to 24A AC.
Supercharging bypasses the onboard converters.

Interesting, my truck just started doing this as well….

I have the same problem. Scheduled service

Happened to me today also. Coincidence?

Any chance this is a software update issue?

Possibly, if they added additional checks, tightened criteria, or maybe tweaked timing for efficiency and some units can't support it.

Mine started early August. I messaged Tesla and they said they would look into it. Then they closed out my message with no answer. Now they told me to schedule service.

I charge regularly at home and work 2 separate charge cords both 220v, 50 amp and am seeing 24amp rates in both locations not sure exactly what it was doing before but was at least 32 a, I also have the PowerShare wall connector, I need to try that one as well.

Sounds like all of this is a truck hardware issue. Odd that this is happening to everyone and hopefully there is a software update to fix and that it wasn’t a lot of things bugging out at the same time.

Sounds like after software update we all got the same problem
