Coming home from OKC last and went to exit and press my brake and they weren’t responding. They felt super hard and i started just pressing them because I immediately started to panic. Luckily my exit was an incline and there was nobody behind or in front of me so it caused the car to slow naturally to where i could go to the ditch. Talk about scary! My car once in the ditch just turned off. So i started it again because it’s freezing here and when the tow truck driver came i tried to turn my car off and it wouldn’t shut off. Then i again tried to start it and it then wouldn’t start! Up until this exact moment nothing has been wrong. No warning signs on my dash etc! So then i googled this make and model and year and OMG this is a common thing! This scares me because I have kids. The last thing I need is to not be able to break going 70mph!!! It was towed today to a mechanic and is under warranty but i’m extremely stressed about keeping this car! Should I trade it in? does this continue to happen? I don’t know what to do and apparently GMC has zero recalls for this issue even though they’ve been aware of ALL the complaints!!!!
