Complaint Review: General Motors & Chevrolet

I bought new 2016 chevrolet malibu in december 2016. On 7/22/17 was on interstate in VA from home in SC. Suddenly lost steering control. Because the wheels were angled to right was able to get off the road. After sitting for a few minutes I tried the steering again and it worked. Found a nearby chevrolet dealership who couldn't help me & said drive it home. I drove car home pulled in driveway. Grabbed the steering wheel to exit because I am handicapped, and the whole steering column came back out of the shaft and hit me in the chest. Talked to chevrolet & gm and they won't even give me a courtesy car till all their investigations are done. My son starts school on 8/17/17. GM investigator opened door and said "well this is a new one" never seen this before" How many more like this?? How many will die before the investigations are done??
