Brake Light problems of the 2014 Dodge Journey

This car has just a little over 33145 miles and I just found out that the rotors on the back have rusted so bad that they wore out the back bracks and cannot be turned down they have to be replaced. I had my grandchildren in this car less than 2 weeks ago and my car was inspected in August by a Dodge dealer and then I took it back on 8/28/17 because the brake light was on they said the brakes were fine I have it on the invoice front brakes 10/32 80% and 7/32 60% but they said they were fine there no way that rusted in 2 months to that point. I will have midas take a picture of those rotors when they fix my car tomorrow $600. 00 for car repairs this week alone. Dodge need to pay for my rotors and labor and they are refusing because I will not take it back to the dealer. I will not have mine or my families lives risked again. I am done with Dodge two brand new Dodge Journeys in 4 years and major problems with the brakes, low headlight beams and electrical issues not to mention 2 recalls. I just found out today all this.
