car shakes when braking. at slower speeds brakes slip

I dont have enough time right now to list the multiple silly problems this car has caused me. I understand its had 6 recalls I dont think any of them have been done. This model and year is terrible and cadillac she be embarrased to allow people to drive that car. I've dumped thousands upon thousands into this car and I ran out of money to even fix the several problems I still have. I'm sick over it I always wanted a Cad but it was a true let down and hs restricted oppertunites in my life over the last 6 years. I'll neer buy one again makes me miserabe to even think about it !
