2012 Buick Lacrosse stability control problems

I was driving my car down a interstate highway when all of a sudden the stability track can on my dash and the car freaked out and breaked really hard ! I stated to spin out and then a loud crack the lower control arm broke on the rear right side . We almost really lost our lives! This is the 12 time this has happen and the mechanics tell me nothing is wrong they can see!! I'm taking it to buick to see what they say this should be recalled asap! Somebody will get severely hurt soon omg

Takata recall. As I was driving on the highway my vehicle slowed down on its own in the midst of 70 MPH traffic and as I pushed on brakes my vehicle jerked. When I tried to speed back up my car slowly accelerated. I was terrified when it slowed down because the car behind me almost hit me. My car is now give me a warning sign 'stabilize track assist' but I had my breaks check and they were fine. Now I start to smell a burning smell sometimes when I'm driving
