KIA Complaints

The 3.8L Lambda II GDI V6 engine suffered catastrophic failure at approximately 102,000 miles. The root cause is excessive oil consumption documented by an independent repair shop well before the 100,000-mile powertrain warranty expired. At 81,207 miles, during a routine oil change, the mechanic checked oil level before draining and found nothing on the dipstick. Only about 3 quarts drained from an engine with 6.9-quart capacity, meaning nearly 4 quarts were consumed since the last change. This finding repeated at 88,408 miles, with the shop documenting it was the second time oil was critically low. Both events occurred within the powertrain warranty. Original invoices are available for inspection. At no point during ownership did the vehicle display any warning — no low oil level indicator, no low oil pressure warning, no check engine light — despite oil levels falling dangerously low on multiple documented occasions. The absence of any driver alert while the engine operated with less than half its required oil is a serious safety deficiency. The engine failed on while driving with passengers including three young children, causing complete loss of power and requiring an emergency pullover. Loss of engine power at speed creates serious crash risk. The vehicle was serviced at an authorized Kia dealer at 60,449 miles where a 60K service, multi-point inspection, and recall SC243B were performed. The dealer made no mention of oil consumption, did not reference TSB ENG222 (addressing excessive consumption across multiple Kia engine families), and did not perform an oil consumption test. Kia Consumer Affairs refused to submit a goodwill claim and closed the case, citing incomplete oil change documentation — despite the defect being documented within warranty. Excessive oil consumption in 2020-2021 Tellurides appears systemic based on numerous owner reports describing the identical pattern: extreme consumption, no dashboard warnings, and eventual engine failure.

On December 21, 2025, my vehicle experienced abnormal knocking/ticking sounds coming from the engine while driving on the interstate (60 mph), and it was difficult going up hills. The check engine light was intermittingly blinking, and there was a strong burning smell. The vehicle was taken to AutoZone and the code displayed P0304 indicating a cylinder 4 misfire. The spark plugs were replaced. However, the knocking sounds, blinking check engine light, and smell of burning happened again, and I took it PepBoys on December 26, 2025. After testing, they indicated that the fuel injector was cracked and fuel was found in the engine oil. I had AAA tow the vehicle to Cochran Kia [XXX] ). The dealership indicated that they would not be able to look at the vehicle until December 29, 2025. The dealership verified that the check engine light was still on and the motor was misfiring badly. They then checked cylinder #4 with a borescope and found that the valve had a crack in it and that the engine would need to be replaced. There was also damage/scoring to the piston and cylinder wall. The dealership corresponded with Kia (Case #25769914), Kia however indicated that there was no powertrain warranty and that this would not be covered under PI1803 and indicated that only applies to bearing failure, and that dealership should provide me with cost estimate to replace the engine. My vehicle has been properly maintained, and I provided the dealership with the additional requested maintenance records on February 14, 2026. I reached out to Kia Customer Care and they indicated to get the engine replaced under the warranty from the settlement, I had to work with the dealership. I contacted the dealership again on 3/12/26 and they said they can't do a warranty replacement because the warranty only covered if it was the rod bearing.

Vehicle began shifting really hard and the rpm meter started going way up and down really fast. The check engine light also came on. It caused difficulties with control of the vehicle. Vehicle was parked and taken to a mechanic so said the issue was the torque converter and that it needs a new transmission.

The Kia has an active recall sc347a because the side pieces can fall off. Two of ours already have, one of which flew off of our car and was definitely a hazard when it happened. Kia South Atlanta , 7310 Jonesboro road Morrow Road has repeatedly refused to fix it and have made it clear they have no plans to ever fix it despite the recall.

The engine is stalling, knocking and the check engine light will occasionally come on. You can smell carbon monoxide and hot oil. We are having to add a quart of oil weekly.

2019 Kia with approximately 64,000 miles. Engine failed without warning. Prior to failure, vehicle had been experiencing intermittent stalling on multiple prior occasions and had been brought to a mechanic for inspection before the final failure occurred. Vehicle stalled while being driven on a highway at night on [XXX] between mile markers 67-71 in Maryland, creating a dangerous situation for the driver and other motorists. The oil warning light appeared immediately prior to engine failure. Vehicle was towed to an independent mechanic who inspected it and confirmed the engine had failed. The mechanic noted that the engine was well maintained, ruling out neglect as a contributing factor. Mechanic stated this is a known issue with Kia engines from this era. Vehicle is available for inspection. Problem has been confirmed by an independent service center. Engine replacement cost is approximately $6,000. Kia's powertrain warranty does not fully transfer to subsequent owners, leaving this vehicle owner without coverage despite low mileage and what appears to be a manufacturing defect. Owner was advised by mechanic that Kia has covered similar failures as goodwill replacements due to the known nature of this defect.

The oil pressure light is coming on . Even after doing oil change at dealership it’s not going away. Confirmed that the issue was with the oil pressure switch at dealership, which is a common problem for 3.3L V6 engines . Similar issue was observed in other older models with similar engine and the warranty was extended to cover this issue (WTY026).

Car burns oil to the point it requires 1 qt/500 mile. Had oil consumption test when issue first started in 2024 by kia, was told there was no problem. Car has continued to have this issue and has now broke connecting rod due to engine starvation even through the oil is to the full mark. I lost all power while driving with no warning before hand. Kia has admitted these engines have oil consumption issues that can lead to this exact problem and many other consumers have complained of the same situation in which Kia will not replace the flawed engine.

My engine smells like fire and fuel my can will not start or do anything. There was smoke coming out of it. The van has had several issues since buying it. Now it’s completely disabled I heard a popping noise as I was driving and then it died and has not started since.
