I purchased a brand new vechile on Dec 24th. My tires were given me problems and issues. they had to download software again and replace the sensor on the tire. Still one of my tires had pressure issues. I then took my vechile back the second time and they found a nail in my tire. I have called the saleperson twice and left message. He will not return my call. it seems that my tire was defetive at the time of purchase. I want my tire replaced. Please have it replaced and someone call me at 313-581-7399
