I have a Launch Edition 2022 R1S Quad. Last year, it would not charge at either Rivian or Electrify America Level 3 chargers along Hwy 395 between Los Angeles and Mammoth Lakes. This was in August 2024, and I didn’t have the adapter yet. Since it’s about 300 miles to my house, I needed at least one charge along the way.

I stopped at the Olancha Adventure Network charger and tried all three stations, assuming the site was down. I tiptoed to the Inyokern RAM chargers and experienced the same issue. I called Rivian Service and was told to perform the usual reboot, but it didn’t work. Rivian and I agreed that maybe a Level 2 charger was the solution, so I switched to Conserve Mode and drove 45 mph to Palmdale, where the hospital had a faster 21 kW Level 2 charger.

Unfortunately, due to the 110-degree heat, the chargers had been downgraded to 8.6 kW. We ended up sitting there for five hours, ordered Uber Eats, and went into the hospital to cool off. My wife and I took turns holding our Catahoula Leopard Dog under the shade in the drop-off area. After drinking about a gallon of bottled water each, we were back on the road.

I dropped the R1S off at the El Segundo Service Center for a “Sunshine Treatment” so they could run diagnostics. I was given a rental car—thank you, Rivian. It turned out the HV battery and/or the BMS was defective. They installed a re-manufactured HV battery pack at no cost to me.

Now, almost exactly a year later, I had the same problem on my way back from the Bluesapalooza. I started charging at the new Tesla V4 chargers in Coso Junction—no luck. I tried three other stands, then went to the EA chargers next door. Still no luck. I performed four hard reboots, waiting five minutes each time. Nothing worked.

Back on the road to Inyokern, limping along with the GOM (guess-o-meter) showing just 4% battery left upon arrival. Again, no luck at either the Tesla or RAM chargers. I hoped the Level 2 Rivian chargers there would save the day—but they were out of order. Now I was stuck in what felt like hell.

Rivian set up a tow for the next day and arranged a taxi to Lancaster, followed by an Uber home. The total was close to $600, which they said they'd cover, but they only provided a $300 Uber voucher. I had to pay $250 for the taxi out of pocket.

The next day, I met with Rivian at the Havenhurst Service Center and explained the problem. We hooked up to a Level 2 charger in the lot—it charged just fine. They then took it to Burbank the following day, which has a Level 3 charger, and again—it charged without issue. They comped the tow and inspection, but nothing was resolved.

Anybody have an answer???

The only things I can come up with are:

  • Something to do with the altitude (from 8,000 feet),
  • The extreme heat,
  • A software glitch,
  • A fault triggered by the new Tesla V4 chargers,
  • Bad luck,
  • Or maybe the Bermuda Triangle…
All of my payment cards were up to date on Tesla, EA, and RAN.

So far, I’ve used Level 3 charging successfully about seven times without issue. One other oddity: I’ve seen my motor temps spike over 200 degrees while going down the mountain to Bishop. This only happened once and was noted via a data drop to Rivian for review.

Any ideas would help. Rivian hasn’t reached out since, and I get the sense they’ve swept it under the rug because the vehicle is “working now.”

p.s. thanks chat GPT

One more point. I noticed that after trying to charge at the NEW Coso Junction Tesla charger I pulled out the charge cable and went to another stand, the app told me that the bank of #4 -A, B, C and D were out of order. I was at 4 A. I don't know if the Rivian caused it or they were already out of order.

When it does not charge, make sure to press your name on the screen to save whatever is going on to the service log. This might help Rivian diagnose exactly what is going on at the moment when it will not charge.

It's RAN. Rivian Adventure Network. Not b'aaaaah... RAM.

Extreme heat and electornics don't play nice. Plausible. Altitude very unlikely. Fault triggered by V4 Tesla Supercharger very unlikely. Which Supercharger adapter are you using?

Each time it failed, did you try a hard reset? Press and hold far left button on steering wheel and hazard button overhead at the same time until both screens go blank and reboot commences.

When my HV battery was starting to fail I had similar issues, with it not wanting to L3 charge, but then while driving it in the weeks before my service appointment it would charge fine for a couple weeks before having the same issue again.

I hesitate to say that is your problem now since you already had that replaced, but I suppose it’s possible lightning could strike twice? Maybe the BMS this time?

Or, something else in his is causing HV pack to go bad and bad again. Bad 12V messing up BMS, which in turn messing up HV pack?

Yep, also possible. Seems like almost anything can be a symptom when the 12v is going bad.

Used the Rivian adapter sent to me. Yes Hard reset about 8 times with a wait before charging. There was a 40 minute lapse of time from Coco Junction to Inyokern so that should have left enough time for the hard reset to finish.

2 months have passed since this happened. No 12 volt notices.

What adapter are you using at the V4 SC? There has been discussions about the early A2Z had a pin issue where one was too short to use on the V4. I have not heard of it being an issue on other adapters or causing a persistent issue.

I have had no issues with the newer A2Z or the Rivian supplied adapter.

I’m sure you would have checked this but I’ll provide it anyways. I typically charge to 80% and that is what my charge level is always set to. On one of my trips I pulled into a Tesla SC that I had used previously and it failed to start charging. Tried both adapters and a couple of stalls to no avail. Checked and found an EA 5 miles away at the next exit so decided to go there. Same issue, just would not start charging, just as I was about to call Rivian support I happened to see my charge limit was set to 20% and I had 28% in the battery. I never figured out how it got set to 20%, I assume I must have accidentally set it on my phone. Since then it is the first thing I look at if charging does not start.

Good point but I was down to 4% and don't use the scheduling.

You shouldn't be doing that many hard resets in succession. 3 types of resets. And deep discharging of Lithium packs is generally not great for health of battery.

Another thought was the lock mechanism that locks the charger head in the port, so I was careful to push in the charge plug fully. Remember I tries at least 10 charger stands in those few hours. Another point is that i was getting the flashing red light after failure to charge each time.

Getting some great info from the group. I hope this turns into a checklist for Rivianosos, (is that a word?) to follow when this happens.
