General motors Buick customer service Would not fix a continuing problem St. Francis, Minnesota

i have a 2008 buick enclave that was a problem since the day it was bought, they alway fixed everything under warranty till it expired and i was told that is the same problem still occured that they would honor it under warranty since the repair was done so many times, the problem has been with the steering column and it poses a threat to the driver as the steering could not respond, this to is pretty serious, but after the warranty ended, they said they have never heard of such a problem with the steering, but if you look at all the buick enclave forums that are all over the net, they have posts everywhere of the same problem,

my tax dollars bailed out these b*stards and they dont give a crap about you after they get your money, i am telling everyone not to buy from General motors, they make promises they cant keep, they had me take my vehicle into the dealer after the warranty ended to grt an estimate, well the estimate was over 3k with all the same problems that occured over the warranty period, they said they couldnt find any records of my warranty services, so i was left stuck to pay a big estimate fee for gm telling me to take my vehicle in, they will not pay it, even though they made the appointment, once again DONT BUY GM they only want your money, they wont help you in any way shape or form.
