Transmission Not Go Into Gear problems of the 2006 Nissan Sentra

Drove to work, end of day the vehicle would not go into gear. Called dealer and was told that coke had spilled near the gear shift which stopped it from working. I do not drink coke. I was told that this happens to a lot of ladies car. Bumper to bumper warranty will not cover. Tower came carry car to dealer went inside car, pull up cover unscrewed his pen pushed in hole put car in gear. Told me drive to dealer. Tuesday,was told "coke" in car have to pay $500+. Call service manager explain happens how car was diagnosed with "coke" problem before getting there. Did he test car why it did not go into gear his reply same " you spilled coke now it not work". Wednesday went something in car the manager said was sticky, asked did they check to see what it was they said no. Needed to know if I wanted to fix it or was I going to move it off their lot. Many questions no helpful answers all received was "give me the rental car and remove your car off the lot". I gave him the key ask for statement showing I returned car he said no. Asked for the key back to return car myself. I talked to Nissan manufacture turned complaint over to consumer affairs they made me feel less than a person. Asked did they know this happen to this vehicle they said yes. Why do they not tell people or put info on computer he was very rude. Asked why did I not ask if it was going to be a problem if "coke or something was spilled in the vehicle, he told me an economical vehicle not have luxuries of expensive vehicle. If I wanted a water proof vehicle I should have been able of purchasing a more expensive vehicle. I was hurt and asked why did they not have vehicle recalled cup holders in front of the gear shift. No one listen. Gear shift not working properly void emergency brake, have to crank in neutral. On incline car will roll backward out of control not yet no one has been kill yet I was told. Pray no one get kill before this is look into as a serious matter.
