“March 2024 just before hitting 100,000 miles I started having oil consumption issues. Current milage is 137,300 About 10,000 miles ago my check engine light came on. I took it to an auto parts store and it was reading bank 1 O2 sensor. I took it for an oil change and never scheduled for the sensor replacement due to life events. I took it in for another service About 5,000 miles ago. At around 2,000 miles after the service the motor started stalling and sounded horrible. I took it to the dealership and it was 4.5 quarts low on oil. Took it back at 1,200 miles after top off and it was 2.5 quarts low. Started the new motor process which wasn't covered on the extended warranty due to manufactur defect. It cost me 500.00. Before the new motor was in my van started getting me stranded places. Motor wouldn't turn over at all. Got it started went to auto parts store and it was reading 4 bad sensors in bank 1 and 2 (O2 and air intake on the motor). Finally got it to KIA for the new motor told them about they sensors they were supposed to check/replace them when they put the new crate motor in. Picked my van up 3 days ago.

Power train
2 reports
“Oil consumption test failed. Told by dealer the first part of the repair is not covered under the power train warranty because my vehicle is not listed on the list of affected vehicles even though it has the GDI motor that is listed. It's a V6 and not a 4 cylinder and the V6 is not on the list. Dealership in knoxville has done the oil consumption test. Vehicle was bought new in November of 2019 and services have been preformed according to manufacturers recommendation. Van has 104,500 miles on it. Has a 200,000 power train warranty. Kia customer service said it is not covered on the manufacturer warranty because it ends at 100,000 miles. Dealership says its not covered on 200,000 mile power train warranty and Dealership ship isn't responsible because my vehicle and motor are not on the list. I wasn't even aware this was an issue until my van started acting up between oil changes and the oil pressure light came on and the van started stalling. At that time I put 4.5 quarts of oil in it and scheduled the Dealership visit just before 100,000 miles but was told to bring it back if the oil level dropped again. Now it's past 100,000 miles and they didn't register the…”
