KIA Complaints

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.

I bought my Kia ev6 new in October 2022, I have had problems with the charging system. I had the ICCU replaced on 9/12/2024 60,488. I just had to have it towed to the dealership because the same issue came up on 1/2/2026 92,943. It went into check electric system and pull over, then went into limp mode got it pulled over to the side of the road and it died. Dealership has it now and will give updates. I don't charge at DC only charge at home on a level 2 charger.

The checked engine light came on with Code: P219C00. Vehicle was taken to the Kia Perris dealership for maintenance inspection. This happened after the vehicle had to be taken back to dealership for an oil leak post oil change service. The issue has been reported by multiple owners on Reddit. Seems like a manufacturer issue that should be addressed.

My Kia EV6’s ICCU failed while I was driving, leading the car to completely lose power while on a busy street.

Erratic behavior before pulling out of parking lot: STOP vehicle check power, check 12V battery Stop safely engage parking brake. All dash lights started flashing, going black, power couldn’t be maintained, thankfully not on highway yet. Complete car failure, had to have 2025 EV6 jumped 4 times, battery still showed 41% charged, couldn’t keep charge to even get car in neutral for tow or doors locked. After each jump from tow company, power would last for less than 3-5 seconds, then dead, completely dead vehicle nothing worked.

The contact owns a 2014 Kia Optima. The contact received notifications of NHTSA Campaign Numbers: 20V10000 (FUEL SYSTEM, GASOLINE) and 21V331000 (SERVICE BRAKES, HYDRAULIC). The contact stated that while driving at an undisclosed speed, there was an abnormal fuel odor coming from the engine and entering the cabin of the vehicle through the A/C vents. The check engine warning light and ABS warning light was illuminated. The contact stated that on a separate occasion, while driving at an undisclosed speed, the vehicle stalled. The contact became aware that the vehicle was out of fuel. The contact added five gallons of fuel, and the vehicle stalled several miles down the road. The vehicle had again run out of fuel. The contact noticed that fuel was leaking from the vehicle. The vehicle was towed to the dealer, but was not diagnosed or inspected. The contact was informed that the fuel leak had nothing to do with the recall. However, the contact was informed that the battery portal was damaged and needed to be repaired before the recall repair was completed. The dealer asked the contact to pick up the vehicle. The vehicle remained at the dealer unrepaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

Car suddenly slowed from 55 mph to 25 mph because of issues with the 12v battery and the ICCU system. The car is only 1 year old. From looking online, this seems to be a fairly common issue/problem. The dealer is working on it now, but it seems likely that this issue will happen again. If it happens on a freeway, certainly a safety concern.

I own a 2020 Kia Sportage that is currently within the 100,000-mile power-train warranty. The vehicle has been experiencing EXCESSIVE OIL consumption, requiring oil to be added between scheduled oil changes, despite no visible leaks or warning indicators. I have consistently maintained the vehicle according to Kia's recommended maintenance schedule. Oil changes were performed regularly, including some done at home. For those oil changes, I have kept vehicle maintained with regular oil changes and more the last 9 months. There is NO evidence that improper maintenance caused the oil consumption. Will be reaching out to Kia customer service to see what next steps are. Maintenance dept constantly wants to fix things on car that are not needed yet will not report issues with Engine. Very disappointed customer.

While attempting to park the vehicle in an angled parking spot I was pressing the brake and slowing to a stop. Prior to stopping with my foot still on the brake the engine revved and the vehicle surged forward hitting the car in front of me. The emergency braking did not seem to activate nor di my foot on the brake slow the car. The car has been in the shop at least 4 times totaling nearly 30 days for electrical issues. The vehicle had a full charge prior to the drive which was about 6.5 miles. The vehicle was operating in automatic mode utilizing electric only during the trip. What component or system failed or malfunctioned, and is it available for inspection upon request? Powertrain gas and electric emergency braking. It is at repair shop can be inspected How was your safety or the safety of others put at risk? Car accelerated without warning Has the problem been reproduced or confirmed by a dealer or independent service center? Dealer has video of engine surging when switching to electric only mode. I also have many videos. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Dealer only in service shop. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Had check engine light multiple times shorting after buying vehicle. Also has burning wire or rubber smell when charging. Engine RPM's surged when manually switching to electric only mode. Dealer service tech has video and I have multiple videos of this happening. Other items. Car dash says to place hands on steering wheel while hands are on steering wheel. Have video of this. Car has a surging sensation while driving slight gyro sensation. Automatic wipers slow to activate or reactivate during light rain. Have video. Electronics related to android auto and heat AC do not work right flicker disengage and reengage over and over. Have multiple videos of this.

While driving the vehicle and selecting EV only mode the engine RPMs surge to about 3000. This happens frequently and I have it on Video. Kia has had the car multiple times for electrical may electrical related repairs but say the vehicle is normal. The tech line person even had the dealer drive a similar car for a baseline. I would expect they had a baseline prior to manufacturing the car. This is an ongoing unrepaired issue. Date below is first reported date of electrical concerns.
