general problems of the 2007 Saturn VUE

I was driving on the highway going about 65 mph and the car started shaking,brakes. Got really tight car barely wanted to,stop transmissikn was overheating at the same time car wasnt passing second gear everything happened out of nowhere.

My Saturn Vue, year 2007, is making a screeching sound coming from the area of the transmission on startup and gets louder on acceleration. The rpm is overly amped. On acceleration if stutters or feels like it's skipping between gears. This takes place on starting the car to driving on city streets or the highway.

For the past year I have been having a very difficult time inserting the key in the ignition and turning the key to turn on the car. Once I get the key in I have to jiggle it over and over until the key is able to turn. Sometimes it takes me anywhere from 5-15 minutes. However lately when the key is finally in it gets stuck and it does not allow the key to be released leaving me stranded. I also noticed the airbag sensor light turns on and off randomly while I am driving the car and while there is a passenger in the car. My biggest concern is if the airbag fails to deploy in case of an accident. Another concern of mine is that sometimes when I am driving the car it accelerates itself for a moment or two and it is very scary. I am currently unable to drive my car because I am scared, especially because I drive my 5 and 1 year old everyday. I am unable to get the car looked at this time due to financial reasons. My Saturn Vue is not included in the recall however I really wish it were because all of the problems I am experiencing are very similar to that of the gm vehicles that were recalled. Please investigate the Saturn Vue 2007 ignition problem, airbag light problem, and accelerating problem. Thank you so much.
