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. I asked when they called if the engine light was off. They called me back several hours later and said yes. Picked it up at 5 pm 3 days ago. By 8am the next morning the engine light was back on. It's scheduled for 9am Monday. The van has now gotten me stranded 2 times in 3 days. Auto parts store ran the computer and the same 4 sensors are still showing bad. Sensors are in bank 1 and 2. The report on the old motor showed cylinder 1 and 2 oil fouling on the spark plugs (replaced at 100,000 miles by dealer) and excessive oil leakage in cylinder 1 and 2 into the crank case due to carbon stuck piston rings. I was told before the motor replacement that the KIA cares warranty may not cover these sensors. Even though the sensors are going out because they are gunked up with 7 quarts of oil their motor used and they didn't go out until the issue started.
