NHTSA complaint #11470412

Owner complaint summary

After purchasing the vehicle in April 2021, 3 months later upon traveling home and entering an exit ramp the brakes completely locked while going 35-45mph into ongoing traffic downhill and would not allow me to press down on them so that I could come to a stop. I press the emergency brake and that did nothing. I had to glide through traffic into a gas station parking lot almost slamming into a gas pump. The sewer dip allowed the vehicle to slow up and come to halt blocking the traffic. This happened after midnight so I took it to the dealership in which i purchased. No lights appeared on the dash. They advised me the brake booster pressure sensor, brake booster vacuum hose and then after doing so they said non of it fixed the issue, I would need a new brake booster. All totaling over $2000 for a vehicle I had less than 6 months. Shortly after the month following July or August, stalled and the push to start button wouldn’t activate. I waited a few moments and then it turned on, with the engine light lit. I took it directly to dealerships service department and they had it a month, they eventually said it was the Oxygen Sensor and it needed to be replaced. I reached out to GM about all of the issues. They stated there were recalls but not for my VIN. CRAZY Now less than a month, a slight fender bender, another vehicle crossed into my lane, the sensors did not initiate, I had to swerve to dodge from causing any major damage and avoid on coming traffic. My vehicle sustained minor scratches on the front passenger side. Initially 30 minutes after it was running fine. Then the light sensors on the mirrors both sides remained on. No engine lights, no warnings. I’m traveling down the 5 lane Highway @75mph and the vehicle just shuts completely off. I had to get across traffic and avoid causing an accident. The vehicle would not start. Got it towed back into town. Back to the dealership and was advised I needed a new engine! Now I’m without a vehicle.
