Level 3 Charging (only) Not Working

[squinn61853]

Gen 2 R1T
On our way home yesterday, we stopped at an EVgo to charge up. After plugging in, and getting the payment confirmed, I got "Exchanging charging parameters with vehicle" (or something like that) and then, after a while, "Unoplug and try again". Multiple tries failed, on multiple different boxes, and also again at another EVgo location, and then also at a Tesla charging location Prior to leaving, I had been successfully L1 charging, and after these failures, I was able to L2 charge at a Shell. No go with L3 though.

We've been stranded in the Chicago suburbs last night and tonight at a hotel (we live in central IL). After much phone tag yesterday, last night, and today, finally got the truck towed and a rental (it was towed showing 2% SOC!).

Has anyone seen anything like this? Any thoughts on what might be going on? Also, any feedback on the Melrose Park, IL SC? Thanks in advance...

Happened to a few people. It's likely a hardware issue that will require replacement.

Really depends on the backstory here. Is this a brand new vehicle and the first time you tried to L3 charge? Have you ever used EVgo before? Did you try a hard reset? The answer is really different depending...

But yes, multiple failures in a row at an L3 station for whatever reason can cause the vehicle to prohibit L3 charging until a reset is performed (and/or maybe other actions - it's been a while since I last read about something like this.)

Also, L3 charging CAN technically break, or be DOA on delivery, but usually the failure happens one of the first times you use it, not 20k miles down the road.

Do you know for sure that the Tesla charger was open to Rivians? Maybe it was just the EVGo site that was broken.

I personally would have done an L2 overnight to get back to full, rather than tow the thing. If your hotel didn't have a charger (I always book one with a charger so I can get a charge overnight) then you can leave it at a charger and uber back to your hotel. Much less expensive/hassle than towing. And central IL is easily within range if your battery is 100%.

So if the L3 is broken you will need to take it to the service center, but if you can get it working by doing a reset then I wouldn't worry about it.

I didn't really give any details, so...
Truck is exactly 1 year old, and I've done many L3 charges. Yesterday, we tried two different EVgo locations, and multiple charges at each, with the same problem, and the Rivian location was open - got the same failure. We hadn't planned to be staying over night, so I had no hotel reservation, but I found a hotel with charging, we booked, and none of the chargers worked (they were Tesla). So at that point we really had no choice but to get it towed - after our driving around searching for a location to charge that would work, we were down to 5%. It was at 2% when the tow truck left.

Also, during this whole adventure, there were multiple soft and hard reboots while on the phone with Rivian. Oh, and yes, and I had used EVgo before.

I’ve had this issue and have had the truck in for service and Rivian said it’s fine. I’ve had it look at now 3x, I told them this happens at Rivian, Tesla and electrify America L3. The last time they said it was a bad NASC adapter. I asked what about when no adapter was needed and it still failed? They had no answer.

Same thing happened to me a couple of times. No reset would work to reset the charging software. Some think that a sleep cycle will reset it but I did not see that to be the case. For me, once it was stuck in a bad charging loop there was no way out. It did charge via level 2 but refused any level 3 charger regardless of brand. In one case, I fast charged the day before a big road trip with no issue but my first charging stop produced an error and I tried several other locations with the same result. The only thing I could assume was the first charger handle was a little worn and it must have fritzed the vehicle and some safety mechanism prevented it from fast charging. That is just a guess.

More than likely it’s a hardware issue that is sending the vehicle into a tail spin. You can have them look at the charging port itself and a module called the CGM module. I was very upset after the last occurrence and insisted that they change it. They were reluctant but complied. Knock on wood but it hasn’t happened since.

Look up a thread called “Fast Charging Broken”. It was very helpful to me and I documented my story more completely there.

All the best!

I haven’t read this whole thread so sorry if repetitive. I have a Gen 1 quad, and I was coincidentally in Illinois for T-giving. Got stuck at an EVGo at the beginning of my 700 mile drive home when it wouldn’t charge over 19 kw. Service had me hard reboot and screen reboot. That fixed it for 2 charges at EA and EVGo. Got to about WV when it wouldn’t connect again (another EVGo then a Tesla). Hard reboot worked again but I also worried that this was a bigger problem. Had to reset once more at about 4am but made it in with no real problems. Just anxiety.

 

[jlstan]

To balance my experience, should also add the plug and charge at Iona and Tesla is awesome. So easy. No problems on the 700 mile drive out.

Also, the Rivian service folks, I’m sorry I can’t remember her name, were excellent.

I was at Walmart EA charger that did about the same. With six available it was the 3rd one that finally worked. Seemed to be the machine not the vehicle.

I would seek out a RAN L3 station before taking it in.

Hi, I had this issue, and my gen 1 quad randomly stopped DC charging during a road trip as well. Would not charge at Tesla, EVGO, or Electrify America. Level 1 and 2 worked fine.

I’m from Denver but was closest to Salt lake at the time. It was a headache to get addressed.

I had to fight the service advisor because they initially tried to give me the truck back without fixing anything and said nothing was wrong. This is because they plugged into the DC fast chargers at the salt lake center and it worked, however those chargers aren’t similar to any charger you’d encounter on the road so, I refused pickup as I was back in Denver during repairs, until they took it to a public charger.

When they did that, it did not work at either EVGO or EA, and then they actually dug into the logs. Apparently there are data logs on the truck, and logs that can be accessed via the cloud and that is where they saw some issues.

The fix for my truck was doing a degassing procedure on the battery coolant and topping it off. The tech’s theory is the coolant was low enough it triggered a safety mechanism to keep the battery from overheating which caused the issue with the DC charging. To be clear I saw no warnings in the truck, and no specific code was thrown from what I was told. That being said everything has worked great since then.

That being said, when I had my issues I saw a number of threads that referenced the gcm module needing to be replaced. Unfortunately there doesn’t seem to be a well laid out testing procedure for this so you may have to fight for it.

I’ll post my service ticket. Good luck I hope you get it resolved, push the rivian support people to comp you a hotel stay and some charging/gas money. Senior leadership with phone support should be able to if you ask.

I agree with @VSG I would have looked for an L2 charger in the area and charged there, would have been slow but could have charged. L1/L2 use an on board charger that is different than L3 which is DCFC.

I’ve had the on board charger die on my Model S and was able to Supercharge while waiting for an appointment with Tesla to get it fixed. A buddy was just the opposite, on his Tesla DCFC stopped working and he had to use L2 waiting for an appointment.

Sounds like the fast charger module might be messed up. I assume you tried both a full system reset and let it go into a sleep cycle between attempts. If neither of those worked most likely a hardware issue.

Sounds like a failure of the charge control unit. Had a similar thing but the other way around, no AC charging but DC was fine. Rivian replaced the part and back to normal. Funny thing is about 18 later my BMW I4 had a similar problem, same fix.

Same happen to our 2022 pick up, played may games with techs over the phone. Like reboot, hit the any key, turn off blue tooth, walk away for 10 minutes, all very frustrating. Got it into San Antonio service center and they replaced a part and it is working fine. But the lead up to that was very #$$^^& frustrating!
