2021 Kia Telluride

The seat belt buckle in the driver position is failing to latch. It has to be pushed in multiple times in a row and very hard to get the seat belt buckle firmly latched. There has also been more than 1 occasion that I have been driving and all of a sudden the seat belt unbuckles and my seat belt not buckled light and dinging goes off. So it seemed it was fully buckled, but was not. This would be horrible if it unbuckled in a crash! This issues has been ongoing for about 2 months.

Component/System Failure: The engine and lubrication system appear to be malfunctioning. The vehicle has repeatedly experienced sudden engine shutdown while stopped at traffic lights and during low-speed operation. The dealership has identified oil leakage involving the oil pan and oil filter housing and has indicated there may be an internal oil leak within the engine. The vehicle is available for inspection upon request. Safety Risk: When the engine shuts off unexpectedly, the vehicle loses propulsion in active traffic. This creates a risk of rear-end collision and prevents immediate maneuvering out of traffic flow. The loss of engine power while stopped or moving at low speeds presents a serious safety hazard to myself and surrounding drivers. I am concerned that the suspected internal oil issue may lead to catastrophic engine failure while driving. Dealer Confirmation / Reproduction: The issue has been reported to the dealership multiple times beginning in January 2025. The vehicle has undergone multiple inspections and repair attempts, including partial fuel injector replacement, battery replacement, and an oil consumption test. The dealership has acknowledged oil leakage and has stated that replacing the oil pan gasket and oil filter housing may not resolve the suspected internal oil leak. The defect has not been permanently corrected. Inspection by Manufacturer or Others: The vehicle has been inspected multiple times by the dealership. The matter has been escalated to Kia Corporate for review. No police or insurance inspections have occurred, as no collision has yet resulted from the stalling events. Warning Lamps / Symptoms: During each stall event, the check engine light illuminates along with multiple dashboard warning lights. The stalling first began in January 2025. Oil-related concerns and possible oil loss were reported during prior service visits. The condition continues despite repair attempts.

The vehicle decelerated in the highway, from about 70mph to 40mhp with no warning, no check engine light, and no previous symptoms, sounds or other indicators. The vehicle was brought to the dealer who advised the high pressure fuel pump went bad as well as the solenoid and OCV harness, causing oil to be forced through the harness. KIA refused to cover the repairs at 74k miles and it was fixed at the owner expense, even after KIAs long history of failed high pressure fuel pumps in many other models. We were in the fast lane and were almost hit by a semi, who was thankfully able to move over at the last minute, narrowly averting the deaths of both my children, myself, my nephew and brother at aprox 4am.

On 12/24/25 the vehicle experienced the very same issue, on the highway, with my family in the car, coming from Christmas Eve festivities. The car decelerated and NO cel (check engine light) ever came on. when transporting to dealer, the car began rough idling like it wanted to die, but still no CEL. At this time, I am told there is a need for a new engine but no supporting documents or other diagnostic documentation has been shared with me and KIA at this time is refusing to resolve the issue under the powertrain warranty and the car is still under 80k miles (powertrain is until 100k) Additional Info: on Aug 5, 2025, the vehicle, with no warning lights or CEL present, the vehicle decelerated on the highway, putting me and my family in imminent danger (large truck behind us who narrowly missed hitting us) and after about 10 min the CEL came on. the vehicle would not drive above 45mph. Once the car was stopped, the CEL went off and the vehicle was diagnosed as failed high-pressure fuel pump, OCV harness, and solenoid, along with accompanying lines/gaskets/plugs and seals. After the repairs were done, I reported rattling noise to the dealer within 5 days of picking up the vehicle, when I had to bring it in for an axle joint replacement (aprox 8/12/25).

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.

I purchased the 2021 Telluride (former owner of a Sportage, Rio and Sorento). I have our local mechanic handle maintenance and service. After paying $1,400 for a tune up to address misfiring, we quickly concluded the transmission was shot and my engine was burning theough every drop of oil before it was due for a change. I went to Kia of Des Moines, since it is covered under a 200k/20-year warranty. They replaced the transmission under warranty, I shared my mechanic details for records, and they told me they were going to do an oil consumption test. They sent me on my way, asking for me to return after 1,000 miles. I did (and then my car began shaking, but we thought it was due to snow conditions) and they quickly said, "Yes, it is an issue!" My Telluride burned through almost 2.5 quarts of oil in 1,000 miles. I left on 12/15, being told they would have direction from Kia corporate on next steps and acknowledged I need a vehicle loaner during repairs (single disabled mother, who has to travel safely). I did not hear back, chasing for updates. Yesterday, Steven text me saying I would need to authorize $1,600 engine tear down fee in order to confirm issue. I asked for Denny, the manager to contact me. I also called Kia Care, who said it is up to dealer. I am seeing so many issues with Tellurides burning oil. And, I do not have $1,600 to make my vehicle safe - that amount would make me sacrifice my home or another necessity. Google said to fight it and to submit a form to you also. I have to fight this because I have no other choice than to sell an organ. I will stock up on oil to keep filling it so my engine doesn't blow up, but have incredible fear of being stranded and not being able to get my vehicle towed or us home safely. If there is anything you can assist with, I appreciate it. I just found out my parent's 2023 telluride is burning too much oil too - they haven't got the $1,600 sticker, but I know that amount will wreck them also.
