Default Turn signal flasher too fast 2016 LS AWD

Hi All,
First time posting to this forum - THANK YOU for having such a place.
The left turn signal flasher started going too fast so I assumed that the flasher was bad. I bought a fresh one from a dealer. Through grit and determination (certainly not skill) I got the old one out and replaced with new. All good, right? After driving for about 5 minutes the left turn signal was blinking too fast again, right turn signal is normal???
Help!
I know that it is not affecting how the car drives but I'd like to fix. I have done no modifications to the vehicle.

Did you check to see if your turn signals light up. One of your bulbs could be burned out.

I just found out this morning that if your battery's almost dead all the signal lights flash fast, had the car on a ctek mxs 5.0 for about 3 weeks and all the lights were on like it was charged but it would barely turn over. piece o crap

Are there any led's in the front signals burnt out? there are 15 on each side. You could check if the rears are lit up all the way across too.

One of the bulbs might be on the way out (resistance too high) but still work causing hyper flash.

can you replace just one at a time or are they all done at once?

Well, after looking through different part sources - it does not seem like these bulbs are replaceable? Does that sound correct? As they are integrated with the headlight assembly.

Dang! That is impressive.
I'm not convinced I have a bulb burnt out though.
Should I try a different flasher?

Does your car really use 81980-50030 flasher relay? I thought it was an integrated flasher. If it does then can always modify the flasher so it doesn't care about load.

I don't think it's the flasher if the other signals are working fine, so it's left front and rear correct ?
