On June 16th 2019 I drove down to atlanta, ga for a baseball game. Midway I stopped for gas. When I turned back on the truck, I realized that I had lost a and if I get an amount of my braking ability. However, I had no lights on mu dash to indicate a failure to the braking system. I read on a GM forum that other owners experienced the problem, turned off the vehicle for 30 mins, turned back on the vehicle and the brakes worked again. They, however, had lights indicating a brake failure. I followed the forums suggestions and after 30 mins with my truck off, I drove the truck again and had no further issues. I took the vehicle into the service department, but as I expected they could not replicate the issue. I wanted to start a paper trail though incase the issue reoccurred. On July 10th the same braking issue occurred again. This time I was near my dealership in greenville, SC. I took the vehicle to the dealership and they were able to confirm a loss of over 50% of braking but no lights or check engine code (past or present) indicating a brake failure. I am very concerned and believe this truck is unsafe because of the braking issues and lack of confirmation of service lights on the truck dash. It is a death trap. They are not able to confirm a fix either due to not having a service error code to fix and turn off. Vehicle was in motion when issues occurred both times. On both occasion as, serious car accidents almost happened due to lack of braking ability.

My truck has an issue when at low speeds 30mph and under all check warning lights will come on my ESC (electric steering control) will come on when this happens I loose power steering and when that happens the steering wheel returns to center. This has happened three times since buying the vehicle new I had not had the vehicle for a month when all the issue started to happen. When I loose the power steering the power for brakes go out as well I have almost been in an accident because of this it's a very scary situation when it happens. After all the warning lights would come on, power running boards would also cycle up and down on there own, the only light that would stay on was: Service trailer brake system.

With only 500 miles on the truck/engine oil pressure has been dropping drastically while going from drive to idle. It drops frim 60 to under 30. Also battery power gauge drops well below 14 when originally was over 14. This also began at the same time oil pressure issues began.

On trucks equipped with the cheaper low trim backup cameras anytime I touch the brakes while backing up the camera cuts out. It's usually a white flash or solid white line but on occasion will cut out completely to a black screen.

Pulling out of a gas station onto a highway my dash display showed "service power steering drive with care" I noticed I had no power assist to my steering and the steering was extremely hard to steer at best. I also received the message "service ecs" at this point I had little control of the direction the vehicle was going and managed to pull over. I also noticed the following functions stopped working, cruise control, traction control, lane assist, auto stop, etc. I let the vehicle sit about 20 minutes and restarted. No errors remained and I went on my way. Scary situation to be in on a highway.

Multiple warning screens appear on the instrument panel and infotainment screen. They flash on and off, like a light show, and are extremely distracting while driving, especially at night. Each time they flash on they cause me to look down at the instrument panel. I am concerned this distraction will cause me to get in an accident. There is nothing I can do to turn them off. These warnings randomly appear whenever the vehicle is running, be it stationary, in motion, on a city street or a highway, turning, braking, pulling a trailer, not pulling a trailer. This safety risk has been ongoing ever since I purchased the vehicle new one month ago. I live in Minnesota. I have brought the vehicle to a dealership for repairs twice, but the problem persists. I have been told that GM has been aware of the issue since last fall, but has failed to resolve the problem. I took photos of some of the warnings that have randomly appeared and will upload them with this report.

In cold temperatures, this truck constantly throws error codes 'trailer disconnected' 'lane change alert disabled', and 'rear cross traffic disabled'. these errors are extremely distracting and have nearly caused me to get into accidents clearing the errors. GM is aware of the issue but has no solution. Please help.
