NHTSA Complaint #11712068 — 2016 CHEVROLET SUBURBAN

There are 2 components of the vehicle that I believe are malfunctioning. The first component would be the brake system. At first the problem presented itself when going down a parking garage it was approximately 5 miles an hour while applying the brake and the brake suddenly got stuck and really sticky, I had to apply extreme pressure to the brake to get the vehicle to stop completely. It was only after I put the vehicle in park, turned it off, removed the keys from the ignition, open the doors, and then restarted the car afterwards where the brakes would become unstuck. Since that first incident in summer of 2024, there has been other similar incidents when I am breaking in a parking lot at lower speeds, on side streets at lower speeds, or any other circumstance where I would be applying the brake at lower speeds. The brakes would get very sticky hard to press and would not come to a complete stop unless using extreme force. This is a very scary incident because if there was a vehicle a pedestrian and we weren't able to stop the vehicle then we would have crashed and potentially hurt someone. We brought this up to our mechanic and he was not able to reproduce the issue. The engine light does not turn on for this issue and we are not able to produce any engine light codes for the braking issue. This issue continues to happen until this day and it is scary when it does happen. The second component that we believe is malfunctioning has to do with the suspension system, the air ride system. We have taken this problem to our mechanic since 2019, 2020. They've been able to temporarily repair the issue but after some time the part breaks down and we believe that this is a manufacturing issue. There is a warning lamp that appears. What happens is there is air constantly being pumped into the suspension and is drawing electricity from the battery and ultimately affecting other parts of the electronic components.
