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.

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.

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.

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.

I am the owner of a 2017 Chevy Silverado with a little under 50000 miles. I have had an issue with the computer system occasionally re-booting while driving. Also, on occasion, I will get a warning on my display for "trailer braking system" for a fraction of a second. I have mentioned this a several service appointments and inspections, but the dealership was never able to pinpoint the problem. On the morning of Monday, February 28th, I dropped my children off at school, pulled up to the edge of the building and the "trailer braking system" warning flashed for a split second on my display. I proceeded to the stop sign. As I was making the turn into traffic, the computer seemed to have re-booted several times in the period of a few seconds. However, this time, my steering locked in place while making the turn, putting the front of my vehicle just over the double yellow line into oncoming traffic. The doors locked and unlocked several times, several chimes went off, the display flashed a few times, and then, after a couple of seconds, I was able to steer and pull back into my lane. I promptly called Chevy support to report the issue, as I believed this to be an important safety issue that Chevy would be extremely concerned with. I was disappointed to find that the operator was not interested in taking my information, she suggested that I contact the dealership for service, which I already was in the process of doing. I explained that I was calling to report a safety issue to Chevy, not to merely complain, and offered my VIN number. She reluctantly checked the last 8 digits of my VIN number for known recalls and again suggested I call for service. Dealership said that my power steering module needed calibration updates. But, they are not sure that this will solve my issue. I see many complaints like this online and Chevy is not proactively scanning for this computer issue even though it could be deadly in traffic, especially on the highway.

Service trailer brake system is coming on due to faulty safety wire harness have heard of several of these incidents in the same model vehicle there should be a recall

- Waldron, AR, USA

GM already has a recall for brakes going out at low speed this has happened multiple times on this vehicle but there's no recall according to this Vin, the second is the transmission shakes the entire vehicle violently at higher speeds, commonly known as the "chevy shake." Multiple dealers refuse to look at the truck charging upfront fees and saying there's nothing wrong with it since there are no warning lights or other sensors on or reporting any errors, both problems have been recalled on similar vehicles just not for this Vin #, a truck with no brakes can put many at risk

- Houston, TX, USA

I was at a drive through lane yesterday. My truck became hard to slow down and stop. I had to push the brake pedal very hard to stop to avoid crashing the car in front of me. I had to do the same on way home approaching stop signs and traffic lights. When turning to and park at our driveway, it was hard to make stop and park also. I heard some noise from power braking system and felt the truck shaking.
