Affects the following:

2019 CHEVROLET MALIBU HYBRID Complaints
The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that the vehicle experienced various intermittent electrical failures while driving at various speeds. The contact stated that the power locks and windows either failed to operate as needed or independently operated while driving. The vehicle was inspected by a friend, and a potential issue with the ground fault cable was found. The friend recommended that a dealer inspect the vehicle. The contact stated that the instrument panel intermittently displayed the messages, "Steering Column Lock Needs Service", "Check Engine", and other unknown messages. Additionally, the brake pedal depressed to the floorboard while attempting to start the vehicle but resumed normal operation after the vehicle was started. The vehicle was taken to a dealer but has not yet been diagnosed or repaired. The failure mileage was approximately 80,000.;
2020 BUICK ENCLAVE Complaints
My car starting making a loud noise upon start up and continued while driving, sounded like a GoCart exhaust system and was not normal. It just sounded loud and would get louder when accelerated until the car ran for awhile. I first noticed it at about 83,500 miles. I took to the dealer for checkup at 83,950 miles when I could get an appointment. The dealer (Elco Chevrolet) confirmed the problem upon hearing and looking under the car, there is a bracket broken on the exhaust system and the catalytic converter has a hole/crack in the molding. Our safety is at risk if the exhaust with the crack would create fumes harmful when driving the car and risk of injury if the exhaust would fall off upon driving due to bracket broke. There were no warning lamps or messages from the car. I am submitting this problem as upon discussion with the dealer and investigation online about this, appears that this is a problem with GM vehicles with this make and model, Enclave and Travers, however, my year was not flagged for a recall already established. When I tried to investigate with GM they stated it was because my car was not identified likely due to parts or timing. I am asking to further investigate as there may be a problem with the design of this exhaust system that caused this issue early in the mileage of this car. Asking for further investigation into the make and model of this year for the year 2020.;
