Automatic Emergency Braking problems of the 2016 Chevrolet Tahoe

Hello, I has problems driving my car like by brakes braking out of nowhere. There was even a couple times I felt like the car swerved, even though I did not do anything to the steering wheel. Then I found out I had a recall that said not to drive the car because it was dangerous so I parked it in my driveway and I have not driven it for many months as I’ve been getting rental cars. Eventually, I brought it into antelope valley Chevrolet and they told me they were going to fix it but then they actually told me that I had to pay around $1000 for a part that I found out later only cost under $100 and takes three minutes to put in. This is apart from Chevrolet and not some knock off from china that I found for under $100 online. So I’m a little upset that I came in for a recall and they’re trying to get me to do a repair for almost $2000. They never even offered me a rental car and they’re threatening me saying that if we don’t move forward with it, they’re gonna charge me $50 a day for storage. I feel like they’re intimidating me to try to make me traded in for a new one, but I am not ready to get a new one. I just want to get my car on the road again.

-malfunction---while driving, when I press the brakes to come to a stop, it seems as if the brakes catch but then releases and then catches again. As it releases, it continues to roll. Vehicle is availabe upon request. -safety risk--- because the brake releases and/or eventually not catch at all, this is unsafe because I can roll into traffic -reproduced and/or confirmed--- I have brought my vehicle to a service center to repair a recall and was told to that the issue should be resolved once the recall was complete. The issue was temporarily resolved for approximately one month or so, and now it is back to breaking and releasing. -one can only assume that the vehicle and/or its components have been inspected given that I brought the vehicle to the service center, stated the issue, and was told that the issue should be resolved after it has been serviced.  -there were no warning lamps, messages, or other symptoms of the problem prior to this issue.

I was driving down highway and saw a wall of cars and brake lights in the distance, so naturally my foot tried to push the brakes. The pedal was hard, and I panicked because my Tahoe was not stopping at all! I continued to stomp on brake pedal all the way until my car actually hit 3 vehicles and then the guardrail! my brakes did not work , because if they did then I would have easily prevented this accident!!.

Its seems that the abs computer stopped working and the break and traction control assist also.
