Antenna fin blew off while driving. . And broke my back window too. I took to dealer wont cover under warranty yet I see all complaints that this needs to be a recall . Dealer wants 450. 00 to replace has to be full unit although radio works fine I need this replaced at kia costs or I will open a class action case for defect. It has happened to much and 2016 got the recall it's the same antenna shark fin cap.
Engine ( and electrical systems ) shut down (3 times) completely and unexpectedly , while car was in motion at highway speeds( twice) and once while at tolls. Also noticed that when you turn key occasionally , its like battery is dead. I believe that first and second times I was flashing hi beams at highway speeds. After these events happen , the mileage guage resets, and clock is wrong. Also notice that the radio flickers,, and or turns off on its own. Also, not able to reset trip mileage, and noticed that shifter button intermittently will not depress.
