   We noticed the passenger side taillight was out. It’s not a simple bulb replacement but an entire assembly. It was put back in place and it lit up again. A few weeks later it wasn’t working. Pounded and tapped on it and it works again. We're guessing there is some sort of short so we asked for an estimate on getting an assembly replacement when it was in for a regular oil change. Shocked that a necessary part would cost $1,112.77!!! Whatever happened to changing a bulb for a…

   Rear LED taillights circuit boards broken. Disabling both Stop tail lights causing serious safety hazard. We had no clue driving around and we didn't have any brake lights another driver had to tell us. So we googled this problem and it turns out that all of 2017 GMC Yukon have the same issue. There's even multiple websites to repair them as well as auto supply stores selling replacements for $1,000 and the dealership wants $1,500. This is a real problem and GM needs to make…

   Rear (Tail/Stop) lights on both sides, would work intermittently. Turns out it’s a known issue with the LED circuit boards. They consistently break in 2 places, leaving the vehicle with no tail lights/stip lights. GM knows of the issue , but since it’s NOT CONSIDERED a Safety Issue, they do nothing. It’s clearly a safety issue, as following drivers may not see lights, on the rear. Clearly, it is definitely a safety issue, as it can easily cause an accident, not knowing a car…

   Rear brake lights fail due to an issue known by GMC - MULTIPLE GMC YUKON and YUKON XL have this issue. All within the same year. The metal connector in the Brake housing fails and requires it to be soldered or a complete replacement costing consumers $800+ for replacement. A severe safety issue as the Brake Lights quit working!!

   The right side break light works intermittently. It is out more than on. I was informed that there is a shortage in it and the entire assembly has to be replaced. I see countless GMC Yukons with the same light out. This is a huge safety issue.

   I purchased a 2017 GMC Yukon Denali brand new off the showroom floor. I have maintained the services thru GMC dealership. I had to replace the struts and rear and front shocks due to hydraulic system leaking and locking up my brakes and causing extra pressure on my braking system to stop my vehicle. This cost me over $5000 to replace out of my pocket and I saw there was a previous recall in 2019 for similar problem but i was told my issues were not covered under the recall.…
