NHTSA Complaint #11503350 — 2016 CHEVROLET SUBURBAN

I am wanting to report an issue with my 2016 Chevrolet Suburban, yesterday no January 23,2023 as we were driving on the highway my suburban suddenly stopped going into drive and the RPM's shot all the way up. We were going 65mph and were almost hit by an 18-wheeler that was behind us. We got to an exit and had to stop it scared our kids, the check engine light came on and were only able to drive 20 mph to make it home safely. We had the check engine light that came on checked and it came back with codes P0796 & P0700 we have looked it up and were not able to find a solution to these codes but i was able to find multiple people with the same issue and no solutions for them as well. Prior to the incident the car would accelerate on its own while you were driving. I Have called and searched for a recall but there is nothing listed, I think a recall should be placed since there are so many other people with the same issue. My vehicle has 107k. miles the others have a lot less miles on them.
