I still have yet to have an issue, but within a week of purchase I swapped my LCI US spec tails for ROW amber versions.

The M2 i rented for a day before I purchased mine had this issue.
Fast forward to 6 months later and I buy my LCI M2. Within 2 months of ownership I get the right rear turn signal malfunction. Take it to dealer and they have to replace the whole right rear assembly under warranty.
One month later I am driving and the left turn signal goes out!!
Take it back to same dealer, replaced the entire left rear assembly all under warranty.
This is a common issue that every dealer should take care of.
I will post my receipt of work later if anyone needs the info to take to their dealer.

Having same issue on my 18 LCI for about a month now. As soon as it happened the first time I booked it in with the dealer - they said they would need the car for a day to do a fault finding discovery, however it seems to me like this is a common and therefore known fault.

Right after I booked my car in the issue went away and didn't come back for over a week, by which time I had cancelled the appointment with the dealer, as I thought I would be wasting everyone's time.

The issue seems to be intermittent and irregular but thankfully for the most part the indicator works fine. Every now and again the fault comes back for a short period of time and then usually resets itself after the car is switched off for a while. At the moment this is probably only happening for about 5% of the time the car is in use. I will be due a service in April so I'm thinking of waiting and getting it checked then - unless it gets worse in the meantime.

Turn signal faults are stored. Technician should be able to review the history and confirm the malfunction. My dealer knew my light malfunctioned 4 times and replaced it under warranty even though it has been working perfectly for a week.

This thread busts so many BMW Driver stereotypes: It's not the loose nut behind the wheel that isn't indicating, but a technical problem with said ultimate driving machine...

Hmmm I've had the issue before but if they need to replace my lights that means I'll need to somehow swap over my reverse light overlays!

My dealer just worked on my wiring harness. Seems to have worked so far. I havenít had a problem since.

Their service bulletin said to start with the wiring harness.

Thanks. Please let us know if you ever have the turn signal malfunction again. Because my understanding, and my dealer's understanding, and other's in the thread's understanding, is that replacing the taillight assembly will not rectify the problem.

In my M2, I can go over a month without the issue showing itself, so it may not be immediately apparent it's resolved for you.

Checking in to state just had this issue on my 2018 with 7k miles. Right rear. Chime. Fast signal beep and warning light. I turned it off and repeated without the warning. Will take a pic next time and wait for service

Just to add that to this list, about 6 months ago my right rear turn signal failed and I got it replaced under warranty. Recently, my left rear turn signal failed as well. Booked in next Friday to get that replaced too.

Seems to be a very common fault. What frustrates me is that, in warranty, this wastes my time. Out of warranty, this will cost a lot of money (replacing the entire light unit). I just hope BMW honour replacements outside of warranty because it's a clear design fault. On top of that, I hope they are being sustainable with regards to the units and refurbishing/repairing them. If they are chucking all these units on the dumps simply because of a grounding wire issue, that's just wrong. I'm not even a "greeny" but the thought bugs me.

Do we know or understand if repairing the ground wire will make the original light unit work? Or is the fault damaging the entire unit.

Good to know if out of warranty....
