I just got my 2022 refresh a few weeks ago. This is the 3rd time this has happened to me. I hit the right turn signal, it flashes 3 times like normal then goes into hyper flash and I get an error message on my gauge cluster.

"Check Right Front Turn Lamp"

Has anyone else had this issue yet? I tried some googling but didn't come up with much on the issue.

I've had that happen 4 times now. My truck is not a refresh though, it's a '22 LTD.
Mine was 2 x left rear failure, and 2 x right rear failure.
But...
I have switched my OEM tail lights to Recon tail lights, and these problems only started after the switch. This is 4 times over 3 months, and it only seems to last a few minutes each time.
Let us know if you figure anything out. I'm not planning to take to the dealer as I know exactly what they'll tell me.
 
The only thing I changed was the reverse lights and license plate lights to Lasfit leds. I hope those wouldn't impact the turn signals in any way.
 
I’ve heard GM does not recommend changing out the halogen bulbs to LED.
I changed all mine to LED and haven’t had any problems.
 
I just had the same thing happen right after an oil change. Came on here to see if I’m the only one. Front left turn lamp. Any ideas?
 
I can speak from experience that the voltage on the LED light circuits is VERY temperamental. I fuse tapped my tail light circuit to run amber grille lights and the voltage drop was enough to completely disable the left rear tail light. Once I removed the tap it worked again.
 
My 22 refresh did this the week I bought it about 3 times. Then never did it again. That was back in August. Mine is completely stock.
 
I managed to catch this issue happening twice while the truck was stopped, and both times although the signal was flashing fast and the "check lamp" warning was up; the signal was in fact working. It was flashing fast though.

Happened to me a few months back. I took it to the dealership and while it was there it downloaded a system update over the WiFi. Dealer technicians said that it was a normal thing. Should warn us about that IMO

Hey bro this happening to me now. What was the fix?? Same thing.
 
Anybody find a fix? I have a 2022 high country and it’s been in the dealer so many times for this and actually have TAC engineers at the dealer working on it….
 
Has anybody checked their blinker fluid levels? If low, will standard blinker fluid work, or does GM require a special certified formula? Asking for a friend.
 
if your running stock bulbs, seems that one is not working properly. Could be the bulb itself or the wiring. Older vehicles did the same thing (hyper flashing) to indicate you had an issue, just didn’t have a display to warm you what was going on.

Mine is still doing it occasionally, no clue why. Only thing different is the Lasfit LED reverse lights.

Are your lights stock?
