The daytime running lights (DRL) have failed in the passenger side. After some quick research, it's apparent that this is a widespread issue with the "Signature" halo lights in the Defender headlamp assembly. Reddit discussion: [XXX] ) Here is a Youtube video showing the issue and "fix". So many people have had this same issue that this guy figured out the problem: [XXX] ) The original warranty would have covered it but my warranty just expired earlier this year and the extended warranty will not cover it. The dealership is telling me that the entire headlamp assembly will need trashed and replaced all because this small "chip" within the unit has failed. The cost to repair is close to $3,000. Seeing that the issue causes the DRL's to fail which could lead to a failed vehicle inspection, the issue should be reported more widely and a recall should be issued. Thank you for your time!
