WORST VEHICLE PURCHASE OF MY LIFE!!!

Since I bought my vehicle I have had problems. The vehicle has been send back numerous time but nothing has been fixed as it should be. For example I have send in my vehicle today because of my wipers not working, there seemed to be a short on the wiring. I was informed the my vehicle was ready and the problem was solved, but the driver delivered the vehicle and when he got out he said its still doing the same and that they said it will take a while before it will work. This is very dangerous as today it seems like its going to rain and I have to drive my vehicle with no wiper blades.... This is totally UNACCEPTABLE!!!. I would like top management to contact me about this matter.
