2015 Yukon alternating brake lights

There is a manufacturing flaw in the brakelight assembly that has broken. One of the threads on this site gives a suggested self-repair, but in my experience, it is a flawed repair, and will break again (I've repaired a few that were repaired in this manner. GMC will want about $850 each to replace them, and in spite of what they will tell you, it is not an "improved" taillight you are buying. Give me a call at 480 213 7730, we can discuss the better and more lasting repair that I offer. Thanks!

I just repaired both of my father's that were doing the same thing. If you feel like DIYing it you can tap out the areas on the black plastic and see where it flickers. My suggestion is to Dremel out only that area and find the broken circuit. There are only two spots it can really be anyway so it should be fairly easy. Once you find the broken area I recommend soldering a jumper wire NOT just soldering the circuit back together. A wire will flex but if you just solder the circuit with no wire it will break the next time you hit a pot hole. Once you have the wire soldered on you can JB weld that area back together and voila. If enough people need help with it I I've considered just starting a repair service for it. I'll probably do $75 a light.

GM has finally acknowledged the problem and has issued the following... https://static.nhtsa.gov/odi/tsbs/2019/MC-10169653-9999.pdf My driver's side failed in 2018 and I had the ebay fix done. Been waiting for the passenger side to fail ever since. My truck has 80,000 on it so it is past the 72,000 mile limit in the special coverage. I brought receipts to my dealer showing I had the problem since 2018 and well before the 72,000 miles. The regional aftersales manager was contacted and agreed to do it for half the cost, which was $172.45 out of pocket to have both tail lights replaced. I figured it was worth it since the I thought the passenger side alone would cost over $400 if it failed, even at a discount, since the list for the part is about $700 each. Well after I had them replaced today I looked up the part numbers on the receipt and found them to be as cheap as about $130 each https://www.gmoemautoparts.com/oem-parts/gm-f-lamp-84721531 (right) https://www.gmpartsxperts.com/oem-parts/gm-f-lamp-84721530 (left) They require a core charge so these must be refurbished parts and I guess i didn't get as good as a deal as I thought, but it was still cheaper than paying for the two so not a total loss. If you are past the 6 years/72,000 miles and not able to get GM to offer any coverage at least you can order these direct for far less than the new tail lights.
