Checked my paperwork from 6/4 when my ICCU was replaced and it didn't mention SC311. Called the dealership and they said they didn't show SC311 as completed and that is currently not showing for my EV6 either. @alansh42 do these come out in stages based on VIN? I would think with it being available now that it should be showing for my 2023 EV6 GT in their system.

I just went out to charge, the light was on again. So…

PSA: If you didn’t get the last VSC update, SC273, do not get SC311. It reduces charging yet again.

If I had known about it or if they had asked, I would have said no. I’m down to 9.1 kW displayed on the dash, car scanner shows just 7.31 kW, and my CPH 50 shows 8.17 kW.

What a mess. 😡

Thank you for the heads up. Back when I first asked at my local dealer about the previous VCMS TSB (ELE283), I was advised that it might throttle more significantly than using EV / Settings / AC Charge Current / 90% setting. So I choose not to have ELE283 done. I was experiencing charging interrupted events using my home 40A charger prior to changing the setting to 90%, and have not had any issues in the 9 months since I made the setting change....It is frustrating that Kia is not fully clear and forthcoming about exactly what changes they are making with ELE283, and now SC311.

So, I dunno. It's showing as a service campaign, not "on request" like the previous TSB so it should be indicated for any EV6 in the date range.

Yeah that's what I was thinking too. But it's not showing for my VIN. Another EV6 brought theirs in to the same dealership today though and the dealer called me back saying it showed for theirs, so maybe it's a staggered release.

 

[alansh42]

What's the manufacture date on your GT? SC311 is for cars built 12/27/2023 or earlier.

I wonder if they are doing this in an effort to delay any outcome of the class action lawsuit. To me it sounds like they are stating that the issue is being caused by faulty owners L2 charging connector. I doubt they'd ever admit it was an issue with the charge port on the car itself unless someone could prove otherwise. Either way... if they are saying the problem is being caused by the charger connector they are full of BS

I tend to agree. It sounds as if they’re building in a higher tolerance to the charging parameters that will halt a session. To me that most likely equals reduced amperage and slower charging. That seems to be the go-to for most updates. Maybe that’s not a bad thing but it has the appearance of the engineers having to address the company’s desire to differentiate themselves from the competition - higher/ faster charging - with continual “retrofits “ that address hardware issues (theirs or owner’s) with software solutions.

 

[TechnicallyJeff]

Mine is an early 2023 build

 

[WindyWA]

The Kia has average L2 charging speeds, which is why the problems are somewhat surprising. The F150 (some models) can do 19.2kW compared to the 11kW Kia - although Ford dropped that feature for all but their fleet trucks this year.

I'm sitting at a VBRO far from any fast charger, charging at 1kW and it is working pretty well, with a few short trips during the day I have still rebuilt the charge from 30% to 85% without even trying.

 

[Eternalhope]

I've read through the various pieces of paperwork and as I understand it, SC311's goal is to reduce charge interruptions. A worthy effort IMHO. The way by which KIA is going about it confuses me though.

The TSB and the attached Q&A states (bold mine):
"While charging using a 240-V AC (“Level 2”) charger, the subject vehicles may experience an interrupted charging session or a lower charging speed due to a degraded electrical connection from exposure to a damaged charging cable connector. To improve charging speeds and reduce interrupted charging sessions due to this condition, Kia is conducting this Voluntary Service Campaign to have the latest VCMS ECU software installed on the vehicle."

I keep re-reading the part that leads up to and says "...damaged charging cable connector." That part is what puzzles me. Are they referring to a physical issue with one or more of the AC charge port connectors? Or are they referring to a problem with an owner's L2 charging cable connector? Either way, wouldn't that necessitate a physical repair (or at minimum cleaning) rather trying to overcome it with a software fix?

It seems like making the connection, for lack of a better term, power through a faulty/damaged connector to keep the charging session going could lead to bigger problems. Or am I misunderstanding? Be kind.

Yes, that sentence in particular has me puzzled too. Actually, when I first read it I thought that is WAS talking about my personal EVSA cord or connector. But yeah, it has to be the connector in the car. If that is so there's no way they could fix that with software.

We've had the charge interrupt problem now for almost a year. It's not really that big of a problem as I can typically charge at 40 amps usually on "maximum" and we usually aren't in a hurry. I'm glad that my CPH50 has updated the app so that I can easily change the amperage on my phone.

I want to try a regular cleaning of the connections when we get the car back from the body shop. SUVs do get a lot of dust on the back portion of the car on the road we live on.

 

[jtespi]

So is the new SC311 change to AC charging a "one-strike" behavior per charging session? As in whenever overheating happens, throttle the AC charge rate until the session is over. Or, is it dynamic in that it only throttles the charge rate until the AC inlet temp cools down then it ramps up to the full 48 amps?

I'm hoping for the latter but anything would be better than the current behavior where I'm getting interrupted charging every 10-15 minutes overnight in hot New Mexico 🌡🏜
It took an extra 1-2 hours to do a deep charge from 20 to 90% due to all the times charging was halted and I was imparting 0 kW.

Received my letter today as well. Earliest appointment I could make my dealer was July 17th. Probably all of the software updates as a result of SC302 and now this one.

 

[windracer]

Since my EV6 was already at the dealership, I've already gotten SC311 applied (along with SC302).

This one’s pretty straightforward and shouldn’t take much time.

 

[MYKEV6]

Is 11kW the maximum power the EV6 can take on a level 2 charger? I just received the ECU Voluntary Service Campaign today and want to test if this software update actually fixes the "charge interrupted" error. In order to test this out, i just want to confirm what is the highest KW setting i can set my Home charger to. Thanks

 

[alansh42]

Yes, 11kW/48A is the maximum.

It sounds to me like lawyer speak to try and keep them of trouble from having a potentially crappy charge receptacle on every car. I notice when plugging in the charge cable there is no mechanical resistance that you can feel, and it feels a bit sloppy. I was always surprised at that. Given that it's supposed to be able to handle up to 50A, it doesn't instill confidence in me. Plugging in the 240V 50A NEMA plug on my wall charger takes a significant effort because the blades of the connector are a nice, tight fit with the wall receptacle.
It also doesn't seem like the J1772 connector pins are very large at all (not much contact surface area), but that's a standard that everyone is stuck with for now. All the more reason for those pins to make a nice, snug fit in the receptacle.

Agreed. In the end it sounds like there are three weak points in the first gen EV6, the charging port, the ICCU and the OE 12v lead acid battery. One is an easy fix. We'll see how things go with the other two, but I really don't like the "what if" that's always in the back of my mind whenever I drive our otherwise terrific EV6.

My SC 311 outcome on a 2022 KIA EV 6 Gt-line RWD. Built Jan 2022. No failure/ issue found so just did a software update. I was at the dealership about 2.5 hr but in that time they also washed the car and check a few codes for me. In never noticed an issue since I owned the vehicle just do the suggested service campaign recommendations. I charger 99% on oir home’ s Clipper Creek Level II So max 32 amp in 40 amp breaker. Since I amver in a ruch I reduce my charge amperage down to 60%. And do the KIA recommended 100% full charge once/ month. My range is great. My KIA Connect and Recurrent battery health reports are great!🤞 Safe travels!

I had my 40k mile service done last week ahead of time, since I am planning a road trip soon. My EV6 GT-Line was built in 12/22. The SC311 was performed although I never had any issues. I took the car to a public Tesla Destination Charger afterwards. Normally, all attempts to charge there failed unless I use the remote 'Start Charge' function of the app. This time, I plugged in via the Tesla-2-J1772 adapter and the friendly lady, who seems to be living under my dash, announced 'Charging Started'! Wow! To make sure it wasn't a fluke, I stopped the charge, waited a minute or so and plugged in again - same thing - 'Charging Started'!
Anyone else having a similar experience?
