Air conditioner blower goes on and off intermittently without any pattern. Sometimes it will work for days and then will not turn on again. There is no rhyme or reason to it. Without the blower working I cannot defog / defrost my windshield and gives me poor visibility. Brought it to the Kia dealership they said the fuse wire harness has melted and fused into the engine block. They went on say that it will cost around $5000.00 to fix. Because I drive frequently I am out of warranty. The service desk office manager said she has been seeing more of these come in. Sounds like a manufacturer defect and should be under recall.
The horn for this vehicle simply stopped working. The horn was used earlier in the day to prevent a different vehicle from changing lanes to avoid an accident. My wife has the same vehicle (year make and model) and her horn stopped working 2 weeks ago. The fuse is not the issue on either vehicle. My wife was informed by local Ki…

The horn for this vehicle simply stopped working. The horn was used earlier in the day to prevent a different vehicle from changing lanes to avoid an accident. My wife has the same vehicle (year make and model) and her horn stopped working 2 weeks ago. The fuse is not the issue on either vehicle. My wife was informed by local Kia that this issue has been common. I researched this issue online and several Kia customers have experienced the same issue. This does not seem coincidental, and poses a great safety concern! Customers should not have to front the cost for this as it seems to be a defect in the manufactured line.

Vehicle will occasionally fail to properly initialize its safety systems, causing ABS, Traction Control, FCW, warning, auto stop, auto hold lights to come on and the aforementioned systems to fail. This disables driver assist features and important safety systems. Kia Dealer does not attempt to resolve. Claims that “we parked too close to a tree and the vehicle thinks it was in an accident” would like further investigation from Kia to be performed regarding this issue.

The contact owns a 2021 Kia K5. The contact stated that while driving at various speeds, the Lane Assist feature would illuminate without other vehicles nearby. The contact also stated that the vehicle would independently switch lanes independently; causing the contact to forcefully adjust the steering wheel into the desired lane to prevent a potential crash. The contact manually disabled the features; however, the features independently reactivated. In addition, the defroster failed to operate as needed which obstructed her vision due to fog on the windshield. The vehicle was initially taken to a dealer, but the contact was offered no assistance. The contact then took the vehicle to Kia of Irvine (45 Oldfield Building B, Irvine, CA 92618) where two mechanics acknowledged the failure while test driving the vehicle. The contact was assured by the dealer that both safety features where disabled; however, within minutes of leaving the dealer; the features independently reactivated. The manufacturer was notified of the failure and the contact was given a case number. The vehicle had yet to be repaired. The failure mileage was 17,951.
