Fast turn signal issue
I have a 2012 GS convertible with a fast turn signal problem. Both sides are fast. I checked all the bulbs and connections and all seems to be good. My hazard lights flash at the normal rate. I have 20k miles and no led bulbs installed. Any ideas would be greatly appreciated!!

I have twice and a third time. Super frustrating and now took it out this morning and one minute they both are fast and now normal?? I heard on another forum that bcm I believe could have a broken copper wire causing intermittent issues.

The broken wire idea seems plausible. A broken wire would appear the same as a broken filament in the bulb to the BCM.

Drove it this evening and have discovered that they only blink fast when my headlights are on. When they are off, they work normal. Any ideas?? Thought about changing all the bulbs to rule that out even though they seem to work.

Well i bought all new bulbs and started in the back. No change and then the front. I had no idea but it had led color changing bulbs!! I've only had the car two weeks and assumed it was all original style bulbs. Replaced them with the standard amber bulbs and now it's working perfectly. I did like the look of the led bulbs going from white and amber but not worth the fast blinking. I've kept the led bulbs and maybe at some point it install the necessary resistors to make them work properly. I can sleep at night now that I know it's back to normal!!! 😂
