The "Service Trailer Brake System" pops up on the dash and makes noise every 45 seconds. Its distracting and dangerous to be driving while this is happening.

On Wednesday, 11/15/23, I was sitting in my vehicle while it was parked and running for several minutes. After a few minutes, the alert chime went off and the message "Service Trailer Brake System" was displayed on the dash notifications. This alert persisted for several minutes. Since this initial incident, the same alert has displayed 3 or 4 more times, but while driving. It repeats persistently, causing a major distraction, blocking my speedometer, and disabling bluetooth features. I nearly wrecked because of the distraction and have not been able to tow my trailer because of the risk of of the trailer brakes not working. I have an appointment scheduled with my mechanic on 11/28/23 to get this repaired, but have recently learned of several incidents of this same alert from other GM vehicle owners. This seems to be a defective wire harness and needs to be recalled as it is unsafe and renders the vehicle useless for many intended purposes.

While driving I periodically receive a notification on the dash to "Service Trailer Brake System". The message just randomly comes up with an abrupt warning noise which is a distraction and startles you until it goes away. I don't tow anything with the vehicle. The notification happens about once a month when driving and eventually goes away after a few minutes. I do mostly interstate driving and when the warning comes up, it startles you and you feel the need to pull over immediately. The notification noise is loud and a distraction. I will be taking it to a Chevrolet dealership. I have an appointment late August. This has been going on periodically for months.

Check engine light came on after vehicle starting losing power in steering column. Speedometer was moving up and down with some other gauges doing the same simultaneously. The vehicle provided warning of stabilitrak after dismissed, it gave another warning stating, -??Steering Assist is Reduced Drive with Care.-?? It became harder to accelerate and very distracting as the stabilitrak error continued to pop up with the speedometer and other gauges, such as RPM, going up and down continuously. These gauges would then stop working altogether then start to work briefly. Then, the gauges would continue to malfunction by going up and down with the stabilitrak error on screen. I got off the interstate and I have having issues with acceleration from first gear. Vehicle was hesitating which was terrifying. It was failing to engage. Transmission fluid rose from 187 to 208 degrees during a brief time period on the screen. Could not use the M gear at all.

Car died with no dash warning. Had battery and alternator checked, battery checked out perfectly fine but alternator needed replacing. Replaced brand new alternator. After replacing, message came up -??power steering drive with care-??. Steering went completely hard, no other messages or absolutely any lights on dash. Unable to drive due to car steering wheel being locked. The contact has stated that the dealership confirmed the recall and that this issue is common, yet they have not found anything wrong with the vehicle.

While driving home from corner store, power steering locked up with very little play left or right. My vehicle is undrivable and parked at this time until I figure out what to do. I understand that GM issued a recall for such safety issues in 2018. I just brought my vehicle a year or so ago. Please advise, thanks.

On several occasions at various speeds, both driving straight and turning, my 2015 Chevy Tahoe has turned off. During higher speeds the SUV will turn back on, instantly, by itself but during lower speeds and turning the car has to be manual turned back on by switching into neutral, pressing the break, and pushing the start button. The most recent time this has happened, it was dark outside and I was turning. I lost everything including my head and tail lights so it was hard for oncoming traffic to see me. I also almost hit someone coming in the other lane because I was unable to fully turn due to the loss of power steering. After this happens, I get many warning/action required messages across the dashboard but no check engine light or code have come up. I will be taking it to the dealer but since it does not happen every time the care is driven, I can only hope they can experience what happens.

1.) The wire harness between the body control modules are failing. 2.) When I tow my boat I could loose braking at any time. Display of " service trailer brake system" overrides all other displays on console. Repetitive chiming noise is very distracting and irritating. 3.) Yes, I took it back in soon after i purchased it (a lot of money) and the Chevy rep said it probably was something to do with loose wires concerning the towing. I showed them a picture of the the warning display that I took immediately. They supposedly plugged in a diagnostic reader and said that since the code was no longer showing that they were unable to determine what precisely the issue was, but it was safe to drive. 4.) Component was not inspected by anyone. I was told that if it came on and I was in the area; to bring it in so that they can see the display. 5.) Yes there was a warning message that showed up multiple times. 1 or 2 weeks after being purchased on 3/11/22. I feel that the Chevy reps know of the issue ( bad wiring harness between 2 of the body control modules) and acted as if the had no clue of the picture of the warning display that I showed them and they were able to tell me it was safe to drive even though they said they didn't know what the issue was. "??" I like Chevy vehicles; it would be nice to see Chevy stand behind their product. This is the 2nd Tahoe that I've owned, standing behind your work keeps and promotes customers.

While driving the children to school making a Right turn in the school grounds. The Tahoe completely shut down and restarted. In the 10 seconds it was down I was unable to steer the vehicle and there was absolutely no power. When the vehicle restarted itself the "service trailer brake system", "Service stabilitrac" message come over the display. I immediately took it to the Sun Auto who recently replaced the AC compressor, they kept the vehicle for one day and part of another and they could not find any issues. It seems as if there is battery drainage and this has been inspected by North Side Chevrolet and they have been There are no service indicators and or messages. This is the second time it has done this to me and I am concerned for one my life, the five year old twins I drive everyday and any other people that could potentially be harmed by such a terrifying shut down. Imagine if I am on the highway driving to my job at the hospital and this happens.

Have to researching online it is a very very common issue with the 2015 Tahoes and up. The radio/display screen constantly starts going haywire and scanning through stations changing stations as well as the screen on my gauge cluster which is going to end up causing an accident constantly trying to stop it from scanning and changing stations. It's like the whole screen has a mind of its own

The service break trailer system warning keeps going off when I-??m not towing anything. It-??s to the point that in a 10 Minute drive it goes off about 10 times. I-??ve been to numerous machanics and none of them are able to determine what is causing this issue
