Hello. I’ve got a new 2020 Acadia SLT... great SUV but there’s just one thing the dealer is struggling to fix after a couple of service appointments. The right turn signal operates and sounds fine, but the left turn signal operates fine but makes a high pitched beeping sound with the click. Any idea if these new vehicles are just like a windows computer that plays a sound file for every beep or click, maybe a corrupt sound file? Dealer tried a new front speaker and that didn’t fix it, dealer says grounds are fine. Anyone had this issue or any service guys have ideas? I have a video w sound I may be able to post.
