Is your charging randomly stopping?

[demon_ge]

Update on my service. They ended up having me bring my truck in. Told them it occurs after more extended charging of about 15% or greater. Brought it in at 50%. After about 7 hours Rivian called back and said they determined it to be the adapter, A2Z NACS to J1772, which I brought along. They said the adapter had a “strong hot electrical smell”. While it does have a metal/plastic smell I wouldn’t describe not classify it as how they did. I had my buddy who also has the same A2Z adapter and he says his smells similar and isn’t having any issues.
Also Rivian kept saying they do not support NACS to CCS 3rd party adapters, which this isn’t and I kept saying that but they still continued to say it to include it saying that on my invoice.
To top it off, checking the charging it appears they stopped the charging twice instead of letting it charge a long time.
I’m am frustrated and feel like it’s Rivian just passing the buck and blaming outside influences. In today’s EV market adaptors are a thing we all need to use until everything is NACS which isn’t going to happen for a long time.

Sorry for the long ranting post.

If you have the option, take it to another service center. Maybe your service center is too busy so they bullshit on your request to close it out. My adapter also smells the same and never had an issue. I had to push it pretty frequently before they actually assigned someone to probe around the charging system.

There’s way too many posts about this. There’s a bug somewhere. I’ve used the Tesla universal with that adapter and my A2Z. Stops charging after about 30-40 minutes here at home. My Tesla on the same exact charger? Full 48 A without any issues. Ever. These Rivians hate adapters. Why? Because Rivian thermals suck ass. Always have. Always will

Unfortunately the next closest one to me is Normal Illinois which is 2 1/2 hours away. I’m typing up a reply in the Rivian app now calling out their errors. It’s not a CCS adapter and they didn’t continuously charge it. Also going to borrow my buddy’s adapter and see if I get the same problem.

I have this same problem every time I charge at home with my tesla charger. I have two different adapters and same problem with both.

Does anyone using a Rivian home charger have this problem?

I’m betting that anything that DOESN’T use an adapter is not doing this

So I lowered my amps from 48 to 40 when charging, and no problems now. Charges consistently at about 9 kwh until fully charged.

Same issue here. Tesla home charger with A2Z adapter keeps stopping. Never a problem in the past, just started 2 weeks ago. Saw the post about lowering the amps from 48 to 40 and successfully got it to charge up to 80% yesterday, thanks for the tip! I'll be putting in a service ticket.

No adapters here… hmmm what’s the constant with these issues?

I'm seeing this issue now as well despite not ever seeing for the first 6 months with the same charging setup. It's summertime and very hot in the garage.

Does the Rivian display have any sort of data logging that would shed any light on this error?

I've experienced this on two separate Tesla wall chargers. One a universal and the other a gen3. With and without an adapter (Tesla universal has the right connector).

I talked to Tesla charging support and they say what is happening is that the wall charger gets too warm and talks to the car to slow down charging. The car doesn't do this properly and the wall charger throws up its hands, stops, and does the 7 blink error.

This obviously will only happen when the charging environment is too hot, which is what I'm seeing.

I'm guessing there is a protocol error on either Rivian's or Tesla's part.

My vehicle is currently in service and the service center is escalating to someone else at Rivian.

My guess is an OTA will be required from Rivian to fix it.

I've been experiencing this error, and it is NOT a thermal issue at the EVSE.

Started charging last night at 35%. Everything started at the ambient temperature, 97 F (Houston)

Charging temps after five minutes:
Tesla WC: 109
Cable: 98
Plug at car: 125
NACS/CCS adapter: 115
Car receptacle: 108

At this time the fender on the passenger side was at 108 as well.

Reached 58% and then got the 7 light overcurrent failure:

Tesla WC: 110
Cable: 98
Plug at car: 127
NACS/CCS adapter: 116
Car receptacle: 110

At this point I opened the garage door to cool things off a bit. Dropped ambient temperature to 89 F and finished charging.

Of note: charging proceeded from 35% to 55% at 11.1 kW, at which point charging (per the app) dropped to 10.9 kW. That is, the current drawn by the car dropped BEFORE getting the overcurrent alarm from the TWC.

The TWC is not overheating.

Tesla support looked at my logs and told me what is happening, at least on my wall charger.

2026 R1T with native NACS ports charging on my Tesla Wall Connector (Gen 3) that I never had a single issue with my Model Y in 3+ years, and now I don't know if my Rivian will be charged in the morning because almost every night the charging errors out and stops. I'm always sleeping when it happens, so not really sure what the deal is??

I will say that I did not have as many issues with 2025.22 software, and with 2025.26 it happens almost every night.

I've been having issues with my 2025 R1S where it randomly stops charging usually around 50%. Tesla Gen 3 charger + A2Z adapter. Have had car, charger and adapter since September, this is the first time this issue appears repeatedly. Went to service center today and while checking in the driver next to me reported the same exact issue but with a different charger. My Tesla charger reports 7 red blinking LEDs which according to the manual is a "vehicle overcurrent" issue.

Is anyone else dealing with this?

Be careful how much information you share with the SC. They will tell you that an A2Z adapter with a Tesla home charger is not “authorized” and potentially “violates your warranty”.
If possible, find someone with a non-NACS charger that will let you charge or a public ac (slow charger) to test with…
