I was driving my car and all of a sudden my power steering goes out traction control and park hill assist all flash. This is the second time it has happened traveling 70 mph. I was able to get off of the road but had a difficult time turning the wheel as it felt like it was almost locked. Please advise. Thanks

While stationary after turning on the vehicle there is a hard shift in gears from park to drive. While vehicle is in motion on the city street there is a hard shift around 35 mph to 55 mph. While driving on the city street after 5 miles the vehicle start sputtering and not shifting gears properly then there isn't any acceleration from a traffic light stop and go. And then it picks back up and drive high RPM sound. Or high rev sounds. In addition the gas cap unit is faulty I replaced it before and now it appears it has to be replaced again because it won't close properly. A P0171 code maf sensor came up along with transmission codes for the 5th and 4th gear ratio according to the diagnostics reported from the ob reading and some additional codes that I can't even describe. For the most part the vehicle stalls while driving city and highway which makes it very dangerous to drive
