NHTSA complaint #10892238, filed 2016-08, 25,000 miles“This vehicle has hid headlight assemblies that have constant issues with condensation/water entering the housing and causing the ballast and bulb to fail. This is due to a faulty seal between the outer and inner shell assembly. This is a huge safety issue, as the vehicle may loose all headlights and cause the driver to crash. The assemblies are very costly to replace and the issue is very very common on all 2011 though 2017 Regal and gs models with hid. This is dangerous and should be fixed by the manufacturer. New assemblies will result in the same safety issue in a short amount of time. …”
