NHTSA Complaint #11614674 — 2018 KIA OPTIMA

I’ve had the 2018 Kia Optima for a little over a year. I purchased it as a used vehicle. I’ve noticed that the car is utilizing an excessive amount of oil. Each time I get an oil change for the vehicle I am having to purchase oil to refill the vehicle about 2weeks to a month after. I’ve made multiple road trips where I’ve gotten the oil changed before leaving and I drove around 350 miles; halfway through the drive the oil was half empty on the dipstick. The first time this happened I was unaware of this issue and when I arrived to my destination after around 350 miles of driving, the car had little to no oil. I will provide store receipts of each time I had to purchase oil for the vehicle. I will also provide service interval receipts upon request. Dates of oil purchase are as follows: 1.7/18/23 2.8/16/23 3.10/20/23 4.12/18/23 5.2/7/24 6.2/29/24 7.3/18/24 8.5/4/24 9.5/11/24 10.7/9/24 Service intervals for oil changes are kept up with every 3-5k miles and can provide maintenance receipt.
