2015 chevy 3500 hd has 65,xxx miles on it currently. Truck periodically and usually randomly displays a "service trailer brake" message which constantly goes off when nothing is being towed. Now about 1 in 15 times driven will it not display this message. Ive had the towing brake module replaced and that did not fix this problem. I'm at my wits end with this truck. Chevrolet / gmc need to step up and make this widely known problem a recall. Thanks

As I am driving I am routinely warned about the trailer brake system with or without a trailer hooked up. It is distracting and could cause potential danger while driving. It has been going on for some time and progressively getting worse.

There are several problems I’ve noticed some I fix myself! First of all, I was driving my truck at night on the country road and all of a sudden it starts losing power shut down on me on a little road with no pull over spots in Kentucky and just dies completely. My service charging system light came on. I worked on this forever. I noticed it. All of my grounds were completely nasty and pretty much not making contact. I fix the ones that I can find only two I know there’s more, I’ve changed the generator three times and the battery once, the problem happened again and again and again the only way I can stop my truck from dying is when that light come on if I got out and I took the negative wire off of my battery and then put it back on it would run again for about another three days and then if I didn’t see it, I’m stranded very dangerous. Finally I took it to my mechanic up the road and he basically did the same things. I did something about a door switch also though not another battery another generator and he added new battery cables so far it hasn’t done it again. Now my truck when starting to slow down, it will vibrate and shake you to death. You hit a little vibration in the road say a rumble strip. This thing will shake you through the roof in about make you run into another Vehicle , also, it’s hard to fill up the gas if you have to turn the gas nozzle almost straight up and down if you’re low on gas to make it except it or you’ll be sitting there for 30 minutes putting gas in your truck. I noticed also all of my wheels are having rough spots on them everywhere and they are rusting into . Another thing that happens this truck eats breaks for breakfast. I have put in the past two years at least have the change the brakes, calipers rotors and all twice a year sometimes three times a year. Also, the trailer brake system light comes on nonstop along with a service stability track on when happen. No Wasey no cruise control. I am a masterelect. Maintain truck it ju

Engine loss power while pulling a loaded horse trailer around 10,000 pounds. Error message saying power has been reduced. The top speed while on a hill was abiut 15 miles an hour.tractor traillers had to manuver around me due to the low speed on an expressway with 70 mile an hour speed limit. The dealer said cause was fraying of the wiring harness probably around the turbo. After research on the internet, I found this was a frequent problem. Truck only has 43,000 miles on it. I have requested the old wiring harness for inspection.

I never received a recall on my chevrolet truck which is the same year make and model as this one. Took it to a dealership and had it fixed. They said it wasn't recalled so we had to pay the bill. Isn't their a way to find the recall and get reimbursed for the repair bill and all the associated costs? We have called and made a complaint to the federal safety agency. Nothing came of it. It still is a safety defect that should be repaired with no cost to the customers.

I would notice white smoke coming out under the hood of my vehicle. I would mainly notice it when I would turn on the AC . This would happen either parked or in motion. I would open the hood and the smoke would only last a few minutes, which caused the alternator to catch on fire.

I remote started my 2015 silverado 3500hd duramax. After about 5 minutes of idle time I began driving the truck. About 3/4 miles down the road I detected the smell of something burning or very hot. My first though was it was coming from the outside. Before I could figure out what was burning heavy white/gray smoke starting exiting from lower weather stripping on the rear center sliding window. Before I could take action I heard a loud popping sound. I looked back again and the rear passenger side window was entirely shattered. At this time I killed the rear window defrost and the smoke quite. I was traveling at roughly 20-30mph on a paved city street. It was 35 degrees with a light mist and fog.

Randomly with no needed instance the instrument cluster reads service trailer break. With or without a trailer connected. With the trailer connected the trailer breaks fails to operate causing a very serious safety concern. After pulling to the side of the road as safely as possible with an approximate of 20k pounds with no brakes on the trailer and turning the truck on and then back off the brakes resume as normal. Other service prompts randomly appear on the info cluster on this particular vehicle, but none as serious as this particular one. Such as service front camera, service stabilitrac, and service def system. While these may all be related to the same cause I feel my life and the lives of the general public are being gambled with while the cause is guessed at. I have taken my truck in for these related issues for a total of three times now. Each time I am sent back out to be the test [xxx] in this potential [xxx] trap. The videos were to big to upload to this form. But I have videos of this issue with and without a trailer connected available upon request. Please excuse my profanity!
