2016 GMC SIERRA 2500 Complaints

I keep getting a warning message "service trailer brake system". The warning may come on for a second or it may stay on for 10 to 15 minutes. It may do it once a month or 10 times in a 2 minute period. Whenever this happens I lose the electrical braking system on what I am towing. There is no set pattern or circumstance for when or how long it will happen. I was told if the alert is not on there is not a way to diagnose the problem and since I never know when it will happen I cannot schedule any type of diagnostic service. It does seem to happen more often when it is raining but has happened in perfect weather too. The warning has occurred both when I am towing and when I am not. I've done searches for possible causes and it seems to be a common problem. I regularly tow a 12,000 lb. fifth wheel RV with my family. I cannot afford to lose my ability to stop in a reasonable amount of time. I simply cannot do it when I lose my trailer braking system. The date below is the last incident.

While driving down the road pulling a trailer The steering wheel started to get sloppy it got up to 3 to 4 inches of play in the steering wheel before the wheels return either way The adjustment screw locking nut and clip all came loose and backed out and caused a slap in the steering gearbox The truck became unsafe to drive I had to park the truck until the parts were ordered and the whole gearbox had to be replaced at a cost of over $1500. GM has service bulletins out there on this problem they all came from one assembly factory but they said they would not repair the truck it was under my expense

Tire tread bulged from center line of tire tread to outside of tread approximately 1 ft long. I had been highway driving for about 4 hours at 70 mph. Truck started vibrating and was becoming worse. I pulled over and found bulge in tire. I took it about 5 miles to Matlock Tire in Lenior City Tn. But by this time the tread was cracking and separating. I was able to get a used tire to bring vehicle home. The service person at Matlock Tire advised me to replace all the tires. If one did it they probably all are bad.The tires have been very well cared for. They have 7/32 tread across all the tires. Very even ware. No dry rot. They had been rotated and inspected at McKenny Chevy in Gastonia NC aweek earlier. I had just come through the mountains on route 40 and if the tire had let go it could have been catastrophic. The DOT tire number is from one of the other tires on truck. Matlock Tire kept bad tire. Attachment is invoice for repair and picture of one of other tires on truck.

STEERING BOX ADJUSTMENT SCREW BACKED OUT CAUSING EXCESSIVE SLOP IN THE STEERING WHEEL. THIS IS A WELL DOCUMENTED PROBLEM WITH THESE TRUCKS WITH GM'S SOLUTION IS TO ADD LOCKTITE AND TORQUE NUT. I BELIEVE THAT THIS IS A TEMPORARY SOLUTION AND IT COULD BACKOUT AGAIN. SHOULD HAVE A MECHANICAL LOCK TO PREVENT IT FROM BACKING OUT.
