I will look into the law in Florida on used cars. The sales manager did call back. He stated he spoke to their affiliate GMC Service Manager and they said that it was not a safety issue. Yes, it was about $900 to fix and no way to cover under the warranty. I told him that I had 2 different people that have told me it WAS a safety concern and I will put in a dispute with the credit card company. He told me he would speak with his boss and get back to me. In the meantime, I am going to look up Florida laws to see what I can find. So much help, soooooo grateful! Thank you again
