The " service trailer brake system" light has been coming on for about 3 yrs in my truck. I have asked the dealer about this, and all I hear is it will cost me about $200 just to find out what is causing this. I was also told I could clear this just by pressing the dismiss button, which I have been doing. I don't feel this is the way to fix the problem. Since I do a lot of towing, I feel this is putting both mine and other lives in danger, since I don't know if my brakes are going to work or fail. I have recently discovered that this is a very common defect in this vehicle and is due to a faulty wire harness, which could fail at any time and cause a brake failure. I am truly afraid to operate this vehicle, and feel ALL 2017 silverado's should be recalled, and this faulty wire harness replaced, before people die.

I was driving north on Hwy 60 just south of the Hwy 73 turnoff in Arizona. It was a windy mountain road. I was approaching a vehicle from behind and took my foot off the gas and hit the brakes. Nothing - Nothing. I started pumping the brakes to the floor - still nothing. I was able to adjust my position on the road and travel between the two lanes of traffic - one northbound and the other southbound. I did slightly clip another vehicle. My truck rolled into a stop several miles later. When I was almost at a complete stop - the brakes finally engaged and the vehicle stopped. From where I stopped - it was a flat drive into Showlow, AZ and there was no cell service where I was. I drove at appx 40-45 mph with my emergency flashers along the right side of the road. The truck is sitting on my lot in Lakeside, AZ and has not yet been taken to the dealer for service. Several things to note: I have no recollection of the incident after the initial brakes failed and I took corrective action. My next memory was rolling to a stop on the side of the road. Right after the incident, which driving into town, I suffered a stroke and drove to the hospital. I was released 24 hours later and have since returned to Phoenix. The truck is still in Lakeside awaiting repair.

Service trailer brake warning consistently flashing and dinging, every 1-4 seconds. Taking away my ability to see any digital read out on the screen, not safe to drive with this consistant relentless chiming and flashing on the screen. This issue has ready cost me a battery.

My brakes weren-??t working very good. And when I backed out my driveway I had no brakes at all and almost hit a vehicle. I took my truck to Smith Chevrolet where I bought it in Turlock Ca 95380. Upon arrival they checked it in an provided me a loaner vehicle. I purchased the vehicle with every extended warranty available.. I was within my warranties. I-??m still in my warranty limit. I received a call and was told they need the loaner vehicle back for other customers. I asked if they fixed the issue. The service tech manager and service tech said there was no issue with the brakes. I asked if they got in the vehicle and tested it. They said yes. Problem is I knew they were lying. I arrived to the dealership and I met with [XXX] the general manager cause I had conflict with service manager and service tech. I asked a 30+ year mechanic named [XXX] landers to jump in the truck to test the brake. He said there-??s no reason the brake boosters are defected and should be replaced. But I insisted he still test the vehicle. When tested the vehicle had severe break issues. I was still left with no loaner vehicle and given my truck to take home with brake issues. Come to find out the service manager and service tech were fired. But [XXX] the general manager was the one that let me leave with my truck and no loaner vehicle. It has been a nightmare for a couple years now. I think outside of this I will seek a serious lawsuit against Smith Chevrolet and [XXX]. The brake booster is still not fixed.

1. I lost power steering, power breaks, all dash lights/power and I believe air bags. The truck is available for inspection. 2. The first time I was traveling at 65mph in moderate traffic, it was very difficult to pull over to safety. The second time I was traveling at 50mph on a very windy road with heavy traffic. I almost hit another vehicle head on with several vehicles traveling in both lanes. The last time I was backing into my carport and almost bumped I to my house. 3. No, I called onstar the first time, they did a system check and said everything was good. I called a dealership the Second time and they confirmed I had no open recalls and explained it would be difficult to troubleshoot because it was intermittent. 4. I will be calling back to the dealership in the morning to make an appointment. 5. I got the audible chime, the airbag light came on and the "trailer break" message came on the info center. But everything goes back to normal.

Stabilitrac light and anti-lock brakes lights on.

My Service Trailer Brake System light comes on. This is the 2nd time that I have had to take my truck in for this issue. The first time it was fixed it lasted for about a year. I am not sure what the issue is, but there seems to be a lot of people with this same issue that is very concerning especially when you are pulling a heavy load and the trailer brakes stopped working.

- Ia - North Liberty, IA, USA

Trailer Brake system message comes on multiple time. Have never pulled a trailer. Also when going 75mph on cruise control the "Stabilitrak" message comes up and kicks off my cruise and completely blanks out my screens. This is extremely bothersome and is DEFINITELY a safety issue with this wiring problem.

- Independence, MO, USA

No trailer hooked up and "Service Trailer Brake System" appears. Will dismiss but the chime continues. Would believe this would cause an accident if equipped with a heavy load requiring trailer brakes. Will not be hauling anything with trailer brakes at this point.

- Pooler, GA, USA

Trailer Brake system warning keeps flashing on my display even though I am not towing anything behind my truck. Now I am worried to tow my camper or my boat behind my truck do to this unknown issue, I was told by GM that it may have something to do with a cable assembly harness. I have only owned this truck for 8mos and I dont tow anything on a regular basis. What is going on?? I will get more info when i bring my truck back from GM.

Reporting a common issue in GM vehicles. Trailer Brake Service signal digging on my 2017 Chevy LTZ. CONSTANT DIGGING. Causing distraction while driving, and takes an update to trailer brake modules to fix. This is a common issue, and people need compensated for the money they spent to fix something that is not their fault. This constant service reminder does not go away, and causes a distraction while driving, until the issue is fixed.

Pressing the brakes can cause the trailer brake system alarm to go off. Sometimes it causes the truck to die while I-??m driving. Very dangerous. I have seen numerous posts online of the exact problem.

- Athens, AL, USA

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated while driving approximately 30 MPH, the brakes started to grab while depressing the brake pedal. The contact stated that during stop-and-go driving, the vehicle lost proper braking functionality and occasionally the contact had to depress the brake pedal to the floorboard to stop the vehicle. The power assist service warning light was illuminated intermittently. The contact had taken the vehicle to an independent mechanic to be diagnosed and was informed that the power brake booster needed to be replaced. The vehicle was repaired. The manufacturer had not been informed of the failure. The failure mileage was 60,777.

Brake pressure seems to lose the ability to stop wall at low speeds I have already taken it to the dealer to have a recall done but only a software update was done the problem is still there while braking in low speeds it triggers the ABS and it's hard to break pedal gets really stiff

- Spring, TX, USA

When driving at low speeds and trying to brake, my vehicle's brake pedal fades and fails to stop properly requiring increased stopping distance. This happens when pulling into parking lots, stopping at a traffic device, or in a drive through. There is a current recall for this exact problem that I am experiencing within my model year, however my VIN number does not have the recall. The campaign numbers for this recall are 19V645 and 20V603. I want me vehicle added to the list so I can have it repaired by the dealer before an accicdent occurs. This event has occurred multiple times in my vehicle over the past 18 months/30,000 miles.
