My tail LED lights went out as well, just over 50k and this post is very discouraging. I thought it would be a simple bulb replacement. I am going to call my dealer to find out how much. I have 100k warranty by 3rd party and 100k extended maintenance, I wonder if any of this will cover it...Will update.
