Has anyone seen this error before? I'm trying to avoid the dealer but it may be inevitable. I'm running 100% stock bulbs at the moment, and all of them are working properly. I removed my LED AEs to see if that would make it go away - nope. I also tried replacing front and rear turn signal bulbs. This alert doesn't come up every time I start the car, probably about 40% of the time. Sometimes it will disappear when I start driving. It started happening out of the blue about 2 months ago.
