NHTSA Complaint #11551005 — 2015 CHEVROLET SILVERADO 1500

#1- I had my truck in a few years ago for a brake issues that they said was a computer reprogramming issue and vacuum pump. They repaired and the issue slowly came back. Now it feels as if there is little to no assist with braking and stopping distance is growing. I feel like my family is at risk if there were ever to be a time I need to brake hard or fast. Theire are no warning lamps but obvious excessive braking effort and can feel the brake rotors through the pedal. #2- Intermittently, at low speeds, pulling into parking lots and parking spaces while turning the steering wheel, electrical power cuts out, steering wheel jerks out of hand, and a dash light comes on saying "service stabilitrack". This is a huge safety issue that could certainly cause an accident. I have Googled this very common issue with my year Chevy Silverado and personally checked the grounds on the left and right under the front dash panel by each speaker and found them to be clean and tight. This leads me to believe it is something else and electrical and a huge safety problem. Only issue is that it is very random and hard to replicate. Seems to happen on hot days when I've been driving a lot. I just got off the phone with the local dealership and they are saying there are no other recalls aside from the current one for air bag issues which I just scheduled. But these other issues I feel are definitely safety manufacturer defects/issues especially being that it has been in for the brake issue once already and the steering/electrical issue is such a common thing when searching the internet.
