Tl* the contact owns a 2015 GMC yukon denali. The contact stated that the brake lights failed to illuminate. The brake light was replaced by the contact but failed again a few days later. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 45,000.
The left brake light failed with 57k miles. The right one then failed at 61k miles. The dealer wanted $735 each to fix them, as they claim they need to replace the entire LED housing. The dealer is well-aware that this is a common problem, and it would appear based on googling the issue that many others have experienced this failure from GM.
