Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
NHTSA complaint #11228279, filed 2019-06, 60,000 miles“Brake lights are failing intermittently. Dealer has recommended replacing both tail light housing assemblies at a significant cost of $750 each.
