My drive side tail brake light works inconsistently. What I
am reading, it seems that I would need to replace the
whole light. However I have also been told that the other
brake lights are not working. Has anyone else had this
Common problems. More than likely you need to replace the bulb sockets in the back end. You do not have to replace the hole lens assembly.
I have the same problem brake lights are out on both sides. I was told by the dealer,that the whole assembly has to be replaced at 650.00 per side
I've had the same issue with my 2015 yukon xl Denali. Easiest and least expensive fix is to remove tail light and ship to get fix for $120 at a ebay seller site that specializes in this particular issue. I know the bad side is you have to stop using your vehicle for 2 to 3 days while you get it repaired, but if you have another vehicle and don't want to spend the ridiculous amount the dealer charges for a new one, then it's worth it.
