   Defective wire harness between 2 body control modules, causing alarm to go off repeatedly "Service Trailer Brake System" and also "Stabilitrack" will come on randomly and lock my brakes up and all of the features in my dash. This has been very scary to drive and has brought the vehicle close to collision more than a handful of times now.

   My "Service Trailer Brake System" messages comes on periodically for days at a time with and without my trailer. The loud chime rings consistently for the duration of the drive. It makes driving unbearable. When connecting my trailer to it, the brakes do not seem to function correctly when towing. This is very dangerous. I found out that a lot of my fellow GMC SUV drivers have the same problem.

   LED Brake Lights fail due to design error typically on both side of the vehicle. I have found multiple reports of a failure on a circuit board that was poorly designed. A copper tracing is very narrow and fractures due to vibration resulting in Brake Light failure. Because the entire module must be replaced the repair costs $800-$900 per side.

    LED brake light on drivers side fails to illuminate (noticed first at about 72,700 miles). Upon further research, this appears to be a recurring issue with 2015-2016 Yukon and Yukon XL vehicles. The LED taillight assembly is a sealed housing and the individual brake light bulbs are not replaceable. There appears to be a design defect that is causing premature failures of these assemblies, which results in a safety hazard because the driver does not receive any notification…

    The air in our 2015 yukon has went out and is constantly blowing warm air. Itwill not hold freon. The temps in las vegas get into the triple digits. My 78 year mother constantly uses the vehicle to get places. I have researched the problem and seems to be a constant problem with the design of the ac condenser and hose design. We have been smelling freon for some time so it must have been slowly leaking out. This should be a recall problem since so many people have had the…
