Let me explain, as you may be aware I took my ID4 from San Jose to NYC and back recently. Day 1 was fine. On day 2, while departing Green River, UT en route to Grand Junction, CO our SOC and GOM reading dived from 70 to 24% in a small number of miles. VW did not shine its self in glory - the SOS team was worthless, and my dealer has still not returned my calls. That said, VW has now (several weeks later) escalated the issue, and the car will be going in for an evaluation. Everyone was safe, we made it, but you can learn about it, and more importantly, see the data (I love @EVnotify) here in the video. The full EP2 Roadtrip video will post at the weekend. Thank you to VW for getting involved, it is appreciated - oh, and I love this car so much it's weird.

That had to be quite unnerving and frustrating to deal with. I watched part one of your trip (you even drove through some neighborhoods near our family).

I must say, as much as I love and support EV adoption, I think our Elantra Hybrid is better suited to longer trips simply based on time efficiency and the extra peace of mind. Driving over the hill to Sacramento (I’m in Reno) is a breeze in my Kona EV (and hopefully the same will be true of my ID.4 AWD), but for trips over 300 miles I would still rather drive a hybrid.

Keep us posted and stay safe out there!

If this happens to more than one person, agreed - a significant glitch. Although I guess to you it’s a significant glitch nonetheless. Sorry for your experience, but I am hoping it is not widespread and is limited in scope. I have had no issues (other than the current Car-Net issue not seeing the car) to date that haven’t resolved themselves with a reset or sleep cycle.

Great video!
I am with the earlier post.
VW Roadside would have been my first call.
as it turned out that call would not had been needed! So I would had made the wrong call😁
So I take it the battery ACTUALLY had a good SOC but the software was telling you wrong?
On a side note. Your wife sneezed a few times. Where on earth is your “bless you”😂

Ouch!

FYI, the SOS button will not work unless you subscribe to 'Safe and Secure'
We do have 3 years of free Volkswagen 24-hour Roadside Assistance, and we call them at 800.411.6688
Probably more useful to call AAA if you have it.
Will AAA pamper to our EV needs?
I believe VW roadside will bring a charge to you or a flatbed you to the nearest charging station?

Yow. I am eager to here what conclusion VW comes to.

Just out of curiosity, what was the ambient temperature when this was going on?

My money is on a glitch in the BMS, especially regarding balancing between cells and modules. It is hard to estimate the correct charge on Li-Ion cells already, it is even harder while you're trying to balance out and do other things. While EVnotify pulled data from the car, I doubt much of it was reflecting reality during the episode. Still, very troubling when you're out there and have no charger within reach.

It’s like onstar you have to subscribe nothing is free. I wouldn’t be too worried, Kyle Connor has drive all 3 models of the I.D 4 with no problems. He just did Florida to Colorado in the pro

Actually, for a longer road trip, you tend to be better off with a non-hybrid than a hybrid. Above about 65, the non-hybrid version tends to have better gas efficiency than the hybrid, in large part because it is 1,000 pounds lighter, and the hybrid loses its effectiveness at higher speeds. Additionally, most non-hybrids have a better gear ratio for high-speed driving than its hybrid equivalent.

In 2015 I drove from NY to Florida in a 2012 Camry. I traded that car for a 2015 Camry Hybrid and drove it back. On the way down I got about 32 MPG in the non-hybrid. Coming back in the hybrid I got about 37 MPG. If I remember correctly, the 2015 Hybrid was about 400 lbs. heavier than the 2012 non-hybrid. Both trips averaged well above 65 MPH. Although the cars looked different, the hybrid and non-hybrid drivetrains offered in the Camry were the same from 2012 to 2017. Other vehicles may have different results but this is a real-world observation.

In your Day1 video charging stops you mentioned a couple of times that your were receiving higher than normal GOM charging speeds. Could that be related to the software freaking out on Day 2?

BMS is my guess too, but I didn't think that balancing took place while you were driving.

It could also be a sensor that was glitching out. In the video it was clipped off - I couldn't see the apparent pack temperature.

I still have a Green SOS light and didn't pay beyond the 30-day suspense of add'l services. 🤷‍♂️
I haven't actually used the SOS however.

1, yes there were ions available, but the car could not see them.
2, not my wife, but a good friend. Possibly more nuts than my wife.
3, I am not quite the psychopath it appears, 9/10 times I have already decide what I am about to say, and while driving I just focus on safety and delivery. Nancy, mentioned it. When I am talking, I am essentially deaf through focus.

No, and I need to come back to that point, and ask some questions. EA is reporting charging at 145, while EVnotify shows only 125-129 max into the pack. However the total curve is better that ABRP alpha curves. We were consistently 5-7 minutes ahead of predicted charging models on 0-70% charges

@jongarusa I appreciated you coaching and cheering on your past self after the fact. Did you ever find out why the SOS button wasn't working? I would press it and call back to ask them just about that. I am planning a decently long trip next week (400+ miles each way) and I will press the button to test it first.
