Brake System malfunctioned. Brakes making horrible grinding noise at 25000 miles. Took to dealership under warranty and was told ‘that is just the sound that GM brakes make’ and they refused warranty repair. Assured noise wouldnt worse, but continued. Paid to have brakes replaced and the SAME exact noise continues today. Brake fluid leaked everywhere and totally disabled the entire braking system while driving on the interstate. When the brakes went out, i loss power and it was difficult to steer. Tried receiving assistance from Chevrolet on many occasions until i gave up Car flashed a message suggesting vehicle was experiencing loss of power while driving down interstate, cleared the message and vehicle power remains weak. Code suggested turbo was going out. Car honks 2-3-4 times while in park only 5 minutes. Oil has to be changed constantly. Last oil change took 2 weeks before now having only 81% oil life. Forward collision warning warns when nothing is in front or around you. Lane keeping assistance cuts in and out and dsn’t always work. Backup camera shows upside down often, and distorted. ECM warranty reset has been completed. Lane departure warning signals hazard where there is none and sometimes lane keeping assistance disallows me to remain in the middle of my lane so i have to cut it off. interior and exterior lights and radio have remained on for hours after locking vehicle and going inside my house.
