KIA Motors review: mohave screen unit including gps, dvd, bluetooth is not working only after 12, 000km

I bought the car in January 2015 . from the start I found remote not working for the baggage, windows glass not closing with remote although the car is the top options in KSA. the front tires always covered with black greasy material and in customer service in Jeddah; KSA told me it is the normal of Kia models, this is coming from break. the main problem happened when the screen unit including ;GPS, DVD, Bluetooth stopped functioning only after 12, 000km and the local maintenance agent in Taif city failed to know the cause. it is disappointing to buy a new car with large sum of many to enjoy and then you have to run after maintenance in different cities. also I found in forums this complaint about Kia Mohave screen is common and some of comments that they are using bad quality one.
