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, -€œSteering 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 -€œpower steering drive with care-€. Steering went completely hard, no other messages or absolutely any lights on dash.

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.

Can I even monitor my speed because the message is constantly popping up. Oh Papa that my trailer bikes, don-€™t seem to be working. This could be very dangerous.

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

I purchased this vehicle a few weeks ago. I was told by the Salesman that everything worked in the car. I test drove it and the lane departure warning was working so I assumed the forward collision would be working. In real life driving, I have nearly run in to numerous cars as the forward collision does not work. In one instance, someone slammed on their breaks, my collision didn't alert me, thankfully I saw it, but I had to swerve off the road to keep from hitting them. In addition, the cooling seats work, but the heated seats do not work on either side of the front seats. Lastly, I have discovered that my Navigation system does not work. I can't get it to change to my current location and the GPS is X'd out. This is what I have so far, but sadly, I feel more things are going to happen with this vehicle. I am working with the dealership on the forward collision and heated seats, but don't know if I will get anywhere with them. They have said they will not fix the Navigation system, which is affected by the CAL (calibration) error message on my screen.

On several occasions the following warnings will pop up. Service Stabilitrack, Tighen Gas cap, Service trailer brake system, Automatic collision prep unvailable, and the check engine light will come on. Then the dashboard lights will flicker on/off, the montior will turn black, the doors will unlock and lock. It has happened when I am going 70 MPH down the freeway. And on several occassions the car engine will turn off/stall as i am either pulling into an intersection, parking spot or coming to a stop. I will take it to the shop and have the check engine code scanned/turned off and it will be fine for a week and then start again

Trailer brake system chime goes off constantly. Chevy refuses to fix the defective wire harness. It is distracting and I have no idea if my trailer brakes would properly function if i were to tow. We ranch, but have avoided using my vehicle for this reason. This has happened continuously since 2019.

I purchased a Certified pre-owned Chevy Tahoe, in 2017, for the past year to as of 2/18/2022, the Service Trailer Brake has been chiming. It isn-€™t continuous majority of the time, but I know it isn-€™t right and often alarms me when it does chime. I do not tow trailers behind my vehicle at all. I drive to work and home, take kids to school and sporting events..I would like to know if this has or when will this be recalled" Obviously something is setting it off?"
