Air conditioner went out unexpectedly this week. Front seat usb charging ports went out as well. A few days later I attempted to stop the car by breaking but the brakes would not engage. The pedal felt very hard as if pressure was acting against the cars ability to brake and stop. I had to push down with all my force to keep the car from crashing into another car on 1-95 in Florida. This occurred on November 21st. I was able to manage to get the car back home after traveling for the holiday but the brake failure occurred a dozen more times on both the interstate, surface roads and parking lots by the time we got the car home. The brake assist notification also showed up on the display panel. My family could have been seriously injured or killed! this car is only 3 years old and is not driven that frequently. No reason I should be having these issues. Dealer thinks it is the vacuum pump. Having diagnosed.

The contact owns a 2015 Chevrolet Suburban. While driving approximately 40 mph, the contact attempted to apply the brakes and the brake pedal would not depress. The contact had to apply the emergency brake to get the vehicle to stop. The vehicle was not taken to the dealer. The vehicle was driven to an independent mechanic where it was diagnosed that the master brake cylinder and brake booster failed. The manufacturer was notified of the failure. The VIN was unknown. The failure mileage was 100,000.

I was on slope hill. My brakes are not responding. I put in new brakes 2 months ago and brakes not responding? my car almost went down the hill. I called roadside assistance and had them towed my car to dealership. They found the issue vacuum pump broke. Also my transmission having issue since 2 months. They still haven't found issues. I can't control my speed and engine gives a kick when entering highway. They won't repair this issue because their "mechanics" cannot find the issue. This is this worst vehicle to drive andunsafe for drivers and passengers.
