NHTSA Complaint #11470382 — 2015 CHEVROLET TAHOE

I purchased this vehicle a few weeks ago. I was told by the Salesman that everything worked in the car. I test drove it and the lane departure warning was working so I assumed the forward collision would be working. In real life driving, I have nearly run in to numerous cars as the forward collision does not work. In one instance, someone slammed on their breaks, my collision didn't alert me, thankfully I saw it, but I had to swerve off the road to keep from hitting them. In addition, the cooling seats work, but the heated seats do not work on either side of the front seats. Lastly, I have discovered that my Navigation system does not work. I can't get it to change to my current location and the GPS is X'd out. This is what I have so far, but sadly, I feel more things are going to happen with this vehicle. I am working with the dealership on the forward collision and heated seats, but don't know if I will get anywhere with them. They have said they will not fix the Navigation system, which is affected by the CAL (calibration) error message on my screen.
