I too, didn't find any information on PIT5728B. My truck is still at the dealership. I will call and inquire today.

I have a 2019 Chevrolet Silverado 1500 ltz. I purchased it new 35 days ago. I recently encountered a very dangerous situation. While driving 25 mph, the vehicle lost it's braking ability. The brake pedal was fully depressed but would not stop. The vehicle coasted until it came to a complete stop. The display indicated Service TraiIer Brake System, Service ESC, Brake System Failure, and CEL. I powered the vehicle off and restarted it. The CEL remained on. The other lights went away. The brakes appeared to work better, but when I applied them I experienced a jerking motion. I called my local Chevrolet dealership. I scheduled an appointment that yielded no resolution as my check engine light remained on when I left the appointment. I was told that the problem "might" be a result of starting my vehicle using the "My Chevrolet" mobile app. Further, I was told that nothing was done to repair the issue as they didn't know exactly how to fix the problem. I was informed that the tech did find a service bulletin and based upon the contents thereof, I "should be okay" if I didn't use the app anymore. Further, I was told that I would receive a call when a solution was determined. I was perplexed as to how there appeared to be a lack of urgency/concern regarding a malfunction of something as important as the braking system. Fast forward to three days ago... While driving in traffic, I pressed the brakes again and they were unresponsive. After nearly having a heart attack, I quickly pressed them again and they engaged. (Thank God) However, this is definitely unacceptable. I immediately called GM and my local dealership as I refused to get behind the wheel again. Between the two of them a tow was arranged to the dealer and a loaner was issued as they work to repair the problem. I have been a long time advocate of GM products. However, their quality and service has become subpar as of late. The mileage at the initial brake failure was 2400. The mileage at the second was 2800
