I have very bad experience with Kia I have a Kia Forte 2018 and still under warranty,1st I run out from oil engine because Kia dealerships services are not close screw will wile changing oil & that cost me 1 day sending the car back to fix the issue without say sorry even it s not my mistake, 2nd I have leakage oil from the caliber rer brake once I call to take nearest appointment it was after 2 days and I m using the car for my work & it s not safety to still drive with this safety issue,I decided to change it on the nearest mechanic shop and I brought the old replacement to refund 160$ only from them with invoice & they refused to do.
That was with kia401 Dixie,
This is last time to have Kia car. I m very unhappy with service.
