I wanted to also give an update, I am still getting the intermittent error on my 2023 SE. I agree I get it more frequently on my drive to work in daylight than my drive home in more dusk/dark lighting. I did buy my set from VLand on Ebay. It was supposed to have the replaceable reverse bulb but doesn't. @methorian
I am curious to know if your set has the built in reverse bulb or the swappable ballast. If it is the built in then maybe they are not the same as the ones with the replaceable bulb and thus different causing the errors.
I also reached out to VLand and they responded on ebay saying they have a "accessory" that will fix the error. I asked for more details but haven't heard back yet. I am also thinking to order the set everyone else bought from Amazon to cross test to see if it is the actual taillight unit causing the error or the car/coding/harness. Fingers crossed one of these will solve the problem, it got pretty annoying this morning driving.
