I was driving down the highway and when I went to apply my brakes the pedal completely broke off. It was just dangling on the floorboard. I had no brakes. I was forced to put my car in neutral to slow myself down and apply my parking break in order to stop. The road was very busy and I was going 60mph. I could have died. Luckily I was able to make it over 2 lanes and stop in the grass on the side of the road. I had the car towed to my mechanic and he had to replace the whole brake assembly. I have the broken parts and they are available for inspection. There were no warning lights

Brake failed
I was driving my car to my house an my car started acting funny. While driving randomly 2 lights came on saying service brake assist and service stabili track. It became extremely hard to steer, the automatic brakes stopped working and it cut off on the highway. I put it in neutral and got to the side of the road. When I cut it back on it had the following warning lights; service brake assist, service stabili track. I almost died and my girl had to pay for a tow truck for me to get home and I was right up the street. I feel like it dangerous and when I told gmc they said its nothing they could do. It is several recalls with vehicles just like mine that are the same year with the same problems but they said they would not help me. My car is not drivable and I can not afford to get all the things fixed that were recalls. I am immobile and it is causing harm to me financially. I trusted gmc and I feel like they should do right by consumers.
While going around curves the engine lost power several time. Check engine light came on, power steering failed, power brakes failed and engine restarted on its own after a few seconds.
When garcia buick in santa fe nm drove my car into their shop they said the brake pedal went to the floor and the car almost ran into a wall. They told me the problem was traced to a malfunctioning check valve in the power brake boster pump inlet pipe assembly p/n 20935438. This is a terrible design and a huge saftey problem. The loss of a vacuum assist device should never allow the brake pedal to go to floor and not stop the car.

Service brakes, hydraulic: foundation components: disc
- What is wrong
- General Motors LLC (GM) is recalling certain model year 2014 Buick Lacrosse vehicles manufactured January 29, 2014, through March 31, 2014 and 2014 Chevrolet Malibu vehicles manufactured February 7, 2014, through March 31, 2014, and equipped with 17 inch front brake rotors.

- Remedy
- GM will notify owners, and dealers will inspect the front brake rotors, and install the correct rotors with new brake pads, as necessary, free of charge. The recall began on June 20, 2014. Owners may contact General Motors customer service at 1‑800‑521‑7300 (Buick) or 1‑800‑222‑1020 (Chevrolet). GM's number for this recall is 14128.
