Kia Niro Electric

""When I recently updated the maps I got a message that the maps had been updated. I then got a low 12v battery warning and all displays died. Nothing electrical worked, not power locks or windows. I removed the 12v battery and put it on a trickle charger. Everything worked OK after that, but because the 12v battery shouldnt be depleted by running a map update, I took the car to the dealer. They cleared the integrated charge control unit (ICCU,) which I suspected to be defective. They said the battery was only at 13% charge and should be replaced. The dealer wanted $330 to replace the battery, so I replaced it myself with an Interstate Battery H5 AGM battery ($180 at Costco.) The car has only been in service 2-1/2 years in a mild climate, so thats much too early for the battery to fail. Ill be keeping an eye on the health of the new battery and for any recalls on my car.""

"Phantom drain on 12v battery -- died and had to be replaced 3 times. Kia dealer unable to diagnose. Rendered car inoperable."

"Three times in the past year the keyless entry on my car has failed to work. This seems to be related to the problem Ive been having with the 12v battery not maintaining a full charge."

"Blower stopped working completely. This kept the air conditioning from working. I purchased a new blower and installed it myself. It works fine now."

""I think it was the evaporator that had to be replaced. This happened last May, just beyond the 2yr point of ownership. The dealer replaced the faulty part under the car's warranty.""
