Description of the safety problem On XXX, shortly after starting the vehicle and beginning to drive, I attempted to apply the brakes and discovered that they had essentially frozen up and were not functioning properly. At the same time the vehicle displayed the following warnings: Service ESC, ABS warning light, brake system warning light, "Trailer Brakes Disabled – Service Required," traction/stability control warning, and check engine light. I shut the vehicle off and restarted it. After the restart the brakes appeared to function normally again and most warning indicators disappeared. However, the check engine light remains illuminated, and I have noticed a slight hesitation when starting the vehicle. I have photographs of the warnings taken at approximately 21,029 miles. Relevant history This vehicle was purchased new. The original 6.2L engine suffered a catastrophic failure at approximately 18,685 miles while traveling at highway speed and was replaced under warranty. None of the current problems existed before that engine replacement. Since the replacement, the vehicle has experienced multiple electrical failures, including windshield wipers becoming inoperative while driving in rain, intermittent loss of electrical power and starting problems, steering-related and collision-system warnings, and tire-pressure warning discrepancies. During a recent dealership visit to Ourisman Chevrolet (service advisor [XXX]) for multiple electrical malfunctions, I was told the problem was simply that the battery needed to be charged. The problems have continued, culminating in the XXX braking malfunction. Request I am reporting this as a potential safety defect affecting the braking, stability control, and electrical systems of this vehicle, and I request that the federal safety agency record and review this complaint.

- Repeated check engine lights on for "traction control", "service ABS", and "ESC". - Repaired several components of wheel hub assembly, speed sensor, and breaking module. - Wheel speed sensor repaired 3x - Now dashboard messages are reading "service brake assist", "service steering column", and "service transmission now unable to shift soon". - Athens Chevy never called for a GM engineer and wont return phone calls. We have twin newborns and the vehicle is currently parked in a driveway because we are not confident in its ability to operate safely. I have stressed this to every GM service tech I've spoken to and the lack of concern is concerning in itself.

My car on the dash board said do not accelerate and was shaking and the gear would not go into reverse. When I tried the car would not move. I towed the car to local Chevy dealer and when I told them about N242454441 or related safety campaigns like N242454440 nothing came up for my VIN but was informed GM had this program specifically for my code ( check engine light on) reading P0776 and P0700. This was not covered.
