Most Recent Complaints
The ICCU went out on the vehicle.
ICCU failure
While driving in the evening with an estimated 180 miles range remaining a "pop" noise was heard. About a minute later a vague warning message the car had not displayed before appeared. We tried to make it home but concerning (and still vague) messages kept appearing quite rapidly. The car slowed down and came to a halt and died in an intersection. This all happened within five minutes of hearing the "pop" noise. Once the vehicle died the head and taillights went off and the car would not allow the emergency flasher lights to be turned on. It would not allow it to be put into neutral to allow it to be moved out of the intersection. It also would not allow any of its doors to be locked (manually or otherwise) except for the driver's door until the vehicle was repaired one week later. We found out following that the 12 volt battery had not charged due to a DC/DC converter input voltage sensor fault related to ICCU failure. The popping noise had been a fuse. As the applicable ICCU parts were replaced by the dealership I doubt they will be available for inspection. The safety of my family was put at risk by: - the car's warnings not clearly explaining what the issue was. - the car not giving clear indication of how quickly it would die. - the car dying in a busy intersection. - the car being unable to be shifted to neutral. - the car's warning flashers not being operational when it died in the middle of the intersection at night. - us being left without warmth in outside temperatures around 6 degrees Fahrenheit. The ICCU problem was confirmed by the dealership we purchased the vehicle from. The vehicle was only inspected by the dealership acting on behalf of Kia.
With no warning except a pop, the vehicle iccu will fail and leave you stranded, very dangerous if you are driving on the parkway
ICCU blew along with the fuse
