I JUST bought my car brand new 3 weeks ago. Yesterday as I was driving, my whole brake system just went out. About 6 lights came on the dash and maintenance was flashing. I got it to the nearest Chevy dealer and the Master Cylinder is bad. On A BRAND NEW CAR. A cylinder should last the lifetime of a car…not 3 weeks. The car is not drivable and I am told the parts are back ordered until the end of July. What if my children were in the car when this happened or if I was going 60 mph?? Unacceptable and someone needs to be aware of this!
