I have a 2018 limited and have a problem with the drl. Approx 4 bulbs are burnt or not working on the drivers side. My dealership says they have never seen this before and of course it is not on any kind of warranty. Any thoughts?

 

its a sealed housing, the only way to fix it is to replace entire headlight.

 

Although you are correct, I certainly would "Unseal' it and investigate. Might be a simple bad led strip. If it were the high / low beams I'd reconsider, but drl, meh, get out the Dremel. That said, be prepared to replace and make sure stock is available

 

The DRL's aren't quite LED strips like you can buy off Amazon and eBay. If anything, you'll be looking at replacing individual LED's, and trying to suss out the proper color match... would probably be faster to replace all LED's in both assemblies, unless you can source a broken assembly.
