About three weeks ago, I am driving my kids to school when suddenly there is a warning indicator on my dash saying major braking system failure. Upon calling onstar for a diagnosis, they said to check the brake fluid, sure enough, it was empty. I filled it up and continued driving the car after noticing no fluid where the car is mainly parked. In a week's time, the brakes have started getting harder and harder to press and the vehicle not wanting to stop normally. Taking it to the dealership, I am told that the fluid leaked out into a reservoir at the bottom of the master cylinder. If that cylinder had broke, no brakes. Now, my vehicle has been at the shop for a week because they cannot find the parts needed to remedy this situation. To me it is a safety issue as the car cannot be driven in it's current state although they are still giving me grief as to whether is will be covered under the extended warranty and if they will pay for the rental I am having to use in the meantime.
