Yeah I've had it a few times now. It pops up when you're indicating. I worried it was an indicator out, but they are LED, but I checked them, all working fine, and the message cleared pretty quickly.
I assumed that as LED has very low draw it perhaps gives a false reading now and then. I'll check it when I'm in for a service (Sept), but not too worried otherwise at the moment.

 

For me right turn only, momentary single chime and flash of a warning. Service dept. at dealer “ unable to duplicate”

 

Yeah it's literally been happens on one activation and stopped, a couple of months apart. Hadn't been something I could duplicate, and didn't appear to be any stored errors, so I left it as it's still working.

 

I get this for headlights, turn and stop signals all the time. And there are other chimes that go away faster than you can see what's on the display. My wife calls the car the chimer.

 

I got a headlight alert recently when I started the car in a store parking lot. We drove to the store in the rain. As we drove a quarter mile, the alert dismissed on its own. I am guessing the rain had to do something with the sensor.

 

right turn signal. nearly impossible to duplicate and not on long enough to take a picture. Hopefully if enough of us bring this up to Hyundai, they'll open an investigation

 

I had this happen once when turning left. The turn was kind of bumpy and sloppy so I thought for a moment the car was warning me about something. It went away after I quickly reactivated the turn signal.

I had a similar error for my head lights in the garage, so I got out and saw that the left head lamp was out. I toggled through the headlight controls and the error and light outage corrected.

I’ll keep an eye out for both (only a couple weeks and 400 miles into ownership)

 

I asked my dealer to look at this and they said that the connection was loose and they fixed it. “Tech removed connector R44 and checked pins for bumper harness. Found pin #4 loose and not making proper connection for pin ground. Adjusted pin #4 tension and verified it was no longer loose. Road test and no more warning light. Verified repair.”

 

/ Did the dealer charge? I am having similar issues.

 

I have a 2022 Santa Fe PHEV and had the exact same problem, multiple times. Has happened a few times and it is quick. I will note that comment above and have Hyundai check it next time it is in for service.

 

Same issue with 2022 Santa Fe PHEV, warning chime and extremely quick flash of digital description of problem. The only time I was able to catch it was indicating left rear turn signal and I have seen one quick flash that in all likelihood was right rear turn signal (almost to brief to document). Dealer check and "unable to fault". Problem shows on an irregular basis.

 

I’m still getting the alert but it’s different now. It only shows for a split second instead of staying on for a minute, and it seems to be the rear right one instead of the rear left one now.

 

I have the exact same issue/alert. But it is very intermittent, and it resolves itself fairly quickly.

 

Same here. I think I have it identified to happen when I briefly put on the blinkers and then cancel quickly.

 

Today I got a message saying to check my headlight LED! This also went away after a minute or two. I’m worried these lights are wired properly or the sensors are too sensitive.

 

I had rhat message come up 1 time dealer tech sent case to hitech waiting for response from hitech as per a fix

 

Seems lots of people are getting warning messages when there is really no problem. Just a guess on my part … but I’m wondering if the connectors used to hook up all the sensors are sensitive to vibrations and momentarily lose contact causing the warning messages to trigger???

 

So I did the dialetric grease on the pins that didn't fix it so the dealer just replaced both rear tail light wiring harnessess. Hope this fixes my issue if ur still having it happen tell them to replace rear tailight wiring harnessess.

 

UPDATE: duh duh duh it didn't fix the issue...
The wiring harnessess were replaced and didn't fix the issue. It still comes up started same day I got it done.
Called dealer Thursday afternoon and they transferred me to the SM who told me to fill out this report and send it back as they didn't want to throw parts at it. I'm sorry am I mechanic now cause if so I charge 150/hr.


Does anyone have any idea what to look at next it keeps coming on and disappearing. NO CODES OR STORED CODES IN SYSTEM

Hyundai canada corporate is aware and flabbergasted as to the SM wanting me to do his job. They told me not to do what he said and wait till we get a answer back. I have a sinking suspicion I won't be allowed back to the dealer lol.

 

Had this on a few occasions on my 2023 PHEV. It normally flies away if I cancel the indicator and then out it back on

 

Have the dealer do what I did

 

Only happened once with right turn signal. Went away in seconds.

 

It will come back I thought same thing then bam always came on some times more then not

 

2023 Santa Fe PHEV Limited. I encounter the same thing with the turn signals. Comes on briefly, most times we are talking milliseconds, where it makes the chime and flashes on the right side where the charge/eco/power gauge is located. Last week I was in a drive thru and it came on for more than a minute, advising that the left rear turn signal was out, when I had not even turned on the signal. Annoying at this point. Purchased March of 2023, noticed this around 2000 miles or so. Only 6500 miles now. Also had intermittent airbag light appear at 1300 miles, but that appears to have not come back on since at least the last 2K miles or so. Wish there was a verified fix for these issues. I was curious about the airbag light when it was happening. Unbolted the driver's seat and pulled apart the yellow connector, based on some Youtube videos I saw for Sonatas. The connectors on the male side appear super thin, compared to connectors on other makes I have seen over my lifetime. Wondering if these needle thin male connectors are the cause of continuity issues. Metal expands and contracts, so temperature could increase or decrease contact of the pins on the male and female sides of the connectors. Going over rough terrain or bumps could probably cause continuity issues I would think as well. Just a theory.

 

Have the dealer check the I.C.U. junction box(fuse panel) I'm waiting for my panel to arrive which could in theory fix alot of the electrical gremlins km having. The dealer found the fuse panel was giving false readings. The fuse panel was on back order jn November should be here first week of February.

 

I have had this as well as a number of other similar warnings pop up and then quickly disappear. The most common is telling me to put hands on the steering wheel when my hands ARE on the steering wheel

 

That's a weird kne that means the steering wheel movement sensors aren't working properly. The wheel isn't touch capacitive

 

Anyone eith signal issue get the dealer to check the I.C.U junction box and have them order a new one. Mine took 3 months to come in. It seemed to have fixed the signal issues

 

Issue has come back

 

I have a 2020 Sonata Limited and getting the 'check left turn signal'.

Has been happening on colder days (30-40⁰ F) seems to go away as car cabin starts to warm up
