Speed Control Springs problems of the 2012 GMC Acadia

I bought my car at the end of April. June 27. 2019 was the first time that I had the stabilitrak issue. At 102206 miles, took it to the dealership and was told it was the rr and rf speed sensors and right front and right rear passenger wheel bearings. Today September 9, 2019 and at 103003 miles it happened again. I was driving both times, and both times the brakes grind and I could feel looseness in the gas petal and it squeaks like an old spring bed. I am a disabled veteran and I only use the car to get to va appts, grocery store and general errands. I can't afford to spend another $1,200 to get this fixed. I have read online many of the same complaints. There seems to be an issue with this stabilitrak system and no one seems to know what to do to fix it. Please let me know what steps will be taken to fix this issue before I contact a lemon law lawyer.
