Anyone seen this error before? Just popped up today.

OMG! Never seen that in my EV6 w/ @ 3300 miles on it. Let us know what you find out.

I think this is the same issue. Didn't come up in a search on the error code.

EV6 Motor Control Unit

We had our EV6 for 24 days before a message appeared mentioned a problem with the motor control unit. We were advised to bring the car in immediately to the dealer. Now after two weeks we are still waiting for a resolution. Has anyone else had a problem with this motor control unit?

www.kiaevforums.com

 

U028500 is "Lost communication with active grille air shutter module B". It sounds like an issue with the air flap under the bumper.

 

No kidding?

 

I am unable to find reference to it anywhere.

My dealer is insisting that I bring the car in (which of course I will) to run a full diagnostic next week and won't tell me anything over the phone.

 

The custom DTCs are in the service manual at Kiatechinfo.com (subscription). I subscribed to look some things up.

 

I sent you a private message.

 

Completely unhelpful for your issue, but as a new owner, how do you get that space background?

 

I think that he forgot his duster

 

Update: Today the error went away! After reading that this could be related to the active shutter, I got down there and exercised the vents lightly. Turned the car on and the error has not returned.

 

Just keep an eye on it. Could just be the motors are very sensitive to resistance in movement to keep from burning them out.

 

Had the car checked out today. A full system check revealed nothing wrong. Go figure.

 

I just got the error. Had it in the morning and then it went away. What does "exercising" the vents entail?

 

 

 

YES, The same exact same thing happened on mine yesterday. Less than 400 miles. 2022 KIA EV6 Wind AWD w/ tech package. Its been at the KIA dealer in West Hills Bremerton, WA. They are waiting to hear back from KIA Tech Support on what to do.

 

Mine just went away and hasn't come back. I'm hoping its just software bugs.

 

How did you get the vehicle health report? Showing U028500

 

It was in the phone app. I can't recall exactly where now, but I believe the app had a notification indicator.

 

No alerts or health issues on the app or going thru dashboard of car vehicle diagnostic. Must be a stupid idiot light. Now I need to decide whether visit dealer that seems to have little knowledge on car.

 

I never did it, but someone suggested getting a OBD reader to get any codes. An auto parts should be able o do that.

 

This thread was very helpful to us. We were just about to leave on a road trip after charging to 100% for the first time. Got the Check Electric Vehicle System warning light after pressing start. Ran diagnostic and it was the Motor Control error message.

After reading this thread we realized that one of the front grill shutters was not opening. We left on our trip and booked a service appt in the other city, “when convenient”.

Yesterday it was hot so we started climates using the phone app. When we reached the car both grills were open. We started the car and the error message cleared after 5 seconds. Ran another diagnostic and all good.

Might be unique to our glitch but there you go. Good luck to all!

 

I just had this same issue occur to my EV6 wind + tech package yesterday. Error code on Kia Connect app read U028400. The car is just about a month old with 1200 miles. This morning I pressed on the front grill gently, and when I started the car, the error was no more! Strange things....

 

When I first saw that there was a motor operated air shutter in the front grill, I thought to myself that this is likely going to be a problem in the future. I'm thinking that in winter, ice and/ or snow could easily block or jam up this whole system. What was KIA thinking? Not everyone lives in southern California. There are months in New York when the roads are full of crap (ice, snow, salt, sand) that can (and likely will) jam up this system... This looks like a system that's going to present widespread problems for all EV6's (and maybe Ioniq 5's if they have the same technology).

 

Not that it matters but add me to the list. U028500 at around 4100 miles. Gonna go fiddle with it and see if starts working.

I can deal with stuff like this and I know that gen 1 vehicles are gonna struggle with things more than iterations will. But as the secondary driver of the car it doesn’t matter how I feel. My wife is the primary driver and stuff like this is almost seal breaking. She doesn’t handle stress well and things like this make her feel that car is broken. She also doesn’t do well with a MIL in a brand new car. Just doesn’t look good for the brand or my ability to sell her on an EV6 over a minivan.

 

I did not have the error, but I did have a small branch of a tree that got stuck in the vent when it closed. I was able to tilt the vent a little and remove it.
It could be that something got in the opening and prevented the vent to corretly open/close. Just guessing. But this could explain why error resolved itself

 

Follow up: Trouble cleared on its own with no intervention from anyone ¯\(ツ)/¯

 

Note that there are four additional shutters above the ones highlighted in the photo in post #21 as well...

 

Good point!

 

Got this one tonight. Freaked out when I turned my car on and saw this ominous warning!

Jiggled the bits, but so far the error is still there. Happened to have an appointment scheduled for Monday to drop off for something else so we'll see what they say.

Morning update: warning is cleared.

 

elaborate Phil elaborate what do you mean exercise

 

Elaborate ,elaborate what does exercise mean

 

Please read the thread. Particularly, post 21.

 

Had not seen this until now and know what problem was but exactly same message which did not impact vehicle. Managed to get it in at dealership and problem was exactly as described with air shutter being partially obstructed by unseen small debris. Removed and warning resolved. Will be sure to inspect there again if recurs.

 

Thanks! Just happened to us this morning (Chicago area, and it has been a mild winter and the car is mostly parked indoors so I was wondering what could be wrong. Only 1400 miles on the odometer too!)

Will try checking the vents tonight and also wait it out a few days, glad to know I didn't just go to a dealer right away.

Update: did this while in a parking lot and the error immediately disappeared

 

I didn't realise that I had this problem till I took my EV6 for its first service. The dealer told me that the harness connector to the front grill was loose and all they did was tighten it up.
