NHTSA complaint #11757927

Owner complaint summary

I am reporting a safety concern involving my 2022 Kia Telluride EX with approximately 95,000 miles. The vehicle has experienced intermittent rough running, significant loss of engine power, stalling, and recurring check-engine warnings. During one incident, the vehicle started, sputtered, and shut off. The engine oil level was found to be extremely low despite the vehicle having received an oil change approximately 2,000 miles earlier. After adding approximately one quart of oil, the vehicle was able to start and remain running. The check-engine light subsequently illuminated and Kia Connect reported diagnostic code P000A00. The warning light has intermittently turned off, but the fault remained stored in the vehicle's computer and was later confirmed by a Kia dealership. I brought the vehicle to an authorized Kia dealership because of the oil loss and drivability concerns. The dealership documented that no external oil leak was found and stated that the engine was likely consuming excessive oil. An oil-consumption test was initiated. According to the dealership's subsequent documentation, after approximately 1,000 miles the engine was more than two quarts low on oil. During this process, the vehicle continued to experience drivability concerns including rough running/stalling and poor engine power. I am concerned that the vehicle may stall or experience significant loss of motive power while being driven in traffic. I routinely use this vehicle for commuting and transporting my family. Kia ultimately declined warranty coverage based on insufficient maintenance documentation. I am not submitting this complaint to dispute the warranty decision. I am reporting the underlying safety concern because the vehicle has experienced stalling/loss of power together with substantial engine-oil consumption, and the underlying mechanical cause has not been clearly resolved.
