What 329 owners told NHTSA about the 2021 Kia Telluride

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.

Windshield developed a multipronged crack that does not resemble a normal road hazard crack. After having tried a mobile windshield repair, the results are not successful as the cracks seem segmented and will not accept normal repair. Files include a photo of outside and inside vehicle pic of windshield.

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.

Bought the vehicle in February. The vehicle is burning oil too fast. In 1 week 5 qts. I don't drive much as I work from home. Kia dealer wants thousands of dollars. I paid for extended warranty.

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.

1) What component or system failed or malfunctioned, and is it available for inspection upon request? The panoramic sunroof assembly — specifically the sunroof panel and its track/mechanism — failed. The sunroof panel came off its track and damaged related components (e.g., guide rails/wind deflector arms). The damaged sunroof and broken parts are available for inspection upon request. 2) How was your safety or the safety of others put at risk? The sunroof panel dislodged unexpectedly during normal use. This could have caused objects or glass to fall into the cabin or onto the roadway, presenting a risk of injury to occupants or other road users. Sudden failure of the sunroof mechanism also poses a distraction while driving. 3) Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The dealership/service center inspected the vehicle and confirmed the sunroof panel was off its track and broken. (If the dealer refused to acknowledge it as a defect, state: “The dealership inspected the failure but did not classify it as a warranty defect.”) 4) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle/sunroof was inspected by an authorized Kia dealership service department. (If applicable: “Insurance representatives were not involved.” / “Kia corporate has not inspected the vehicle.”) 5) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages prior to the sunroof failure. There were no abnormal noises or operational symptoms immediately before the sunroof panel disengaged from its track.

Rear shocks unstable. When on rough roads or small imperfections in the road it’s hard to control vehicle and items/people get abruptly jostled.

The oil filter housing is made of plastic and it cracked causing a major oil leak. There were no warning lights on the dash. Our family had just gotten into the car to visit family for Thanksgiving. I ran back into the house to get something and when I came back I first saw a large puddle of oil where the car was parked then I looked at the car and could see oil streaming out. At first I thought the filter or the oil drain plug had come loose. We had our local mechanic look at it and he said it was a common problem they see with plastic housings instead of metal. We called the closet KIA dealership and they said it was a known problem but KIA has not issued a recall. I searched online and found many complaints. If I had not noticed the leak we could have either had a fire or major damage to the engine.

The door belt molding trim detached. It is available for inspection. If not caught before it completely detached it would have caused a road hazard. Models from 2023-2025 have already been recalled but not my 2021 model which has the same issue. The vehicle was inspected by the dealership I bought it from but they were unwilling to take responsibility since the recall didn't encompass my 2021 model. Kia Corp also was unwilling to take responsibility after I brought the issue to their attention. I noticed the trim pealing off the car. It took little effort to remove it completely and I'm glad I did because it would have fallen off while we were driving.

On 11/01/2025, while traveling on the highway traveling at a speed of 80mph, my vehicle suddenly would not accelerate beyond 60 mph. I managed to exit safely, but this created a dangerous situation for both me, my daughter and other motorists . The next day, Firestone inspected the vehicle and informed me the engine contained zero oil—yet no oil light, check-engine light, temperature warning, or sensor alerts were triggered at any point. There were no visible oil leaks, suggesting internal oil consumption, which I had reported to Kia in October of 2024. On 10/21/2024, I paid $3,300 for a flywheel/ignition repair at a Kia dealership. When I dropped off the vehicle for that repair, I specifically reported abnormal oil consumption and requested it be checked. Kia did not diagnose or remedy the concern. The combination of: -Complete oil loss -No warning indicators -Sudden loss of power and inability to accelerate -Occurring at highway speed constitutes a critical safety defect. Drivers cannot take preventative action if the vehicle provides no indication of catastrophic engine failure until it is already occurring. This defect exposes drivers, passengers, and surrounding motorists to severe risk of collision or injury. Additionally, the dealership later provided a Carfax entry simple stating "car maintenance" on 10/22/2024. No record of what was repaired, indicating inaccurate or incomplete documentation. I am requesting that NHTSA: -Review this incident as a potential engine safety defect. -investigate whether other 2021 Kia Telluride owners are experiencing similar catastrophic oil -loss or lack of warning indicators. -Assess whether current recalls adequately address this failure pattern. -Determine whether an additional recall or investigation is warranted.

I tried to open the sunroof and it made a loud "popping" sound then would not close. I took it to the Kia Service center in SC (Fred Anderson Kia Greenville, SC)and the tech informed me this would be a $7000 fix. They also informed me to report this incident since they have also had numerous sunroof issues with this make and model. KIA also released a technical service bulletin " This bulletin provides information to perform a partial replacement of the sunroof wind deflector and mechanism arms on some 2019-2022MY Telluride (ON) vehicles produced from February 15, 2019 through January 19, 2022. The affected vehicles may experience the sunroof open/close operation inoperative and/or the sunroof wind deflector function inoperative. " A this is a known defect, this should be issued recall as it could result in sunroof glass break, causing injury to drivers, passengers.

After having a rear brake replacement on 10/14/25 - was driving to work on 10/28/25, hear a clunk noise that repeated at random. When pulling thru a parking lot I lost my brakes completely. When I parked the car I looked at the brake and the newly installed caliper had fallen apart. Towed to shop to have the vehicle looked and then replaced the caliper with the same brand caliper from the dealership.

After warranty work was performed on my Kia Telluride at an authorized Kia dealership, I discovered that the rear driver-side seatbelt had not been bolted back down. It was completely loose and hanging under the seat. This means my family could have been driving with no seatbelt protection at all. This is a serious safety failure and clear negligence. A seatbelt is one of the most basic, life-saving components in any vehicle. For a dealership to return a car to a customer without confirming all seatbelts are installed correctly shows a complete breakdown in safety inspection and quality control. When I contacted the dealership, I received no apology, explanation, or acknowledgment of responsibility. No one followed up or offered to inspect the vehicle. I also contacted Kia America Customer Relations, but I have not received any response. If such a fundamental safety step can be missed, I am extremely concerned about what other oversights may occur during Kia service work nationwide. This situation should be formally investigated by the NHTSA. I’m requesting a full investigation into Kia’s service procedures, technician training, and inspection protocols to ensure that no other vehicles are returned to customers in unsafe condition. Please treat this as a formal safety complaint. A loose seatbelt is not a minor error, it’s life-threatening negligence. I want this fully investigated and documented under my VIN, with confirmation of corrective action. My family’s safety, and that of other Kia owners, depends on it.

I drive a Kia Telluride and while driving down the highway two pieces of plastic fell down into the passenger seat. Next the window flew up into the air. I had to physically hold the window down while driving with children in the back seat. No warranty will cover the sunroof and I was quoted $6000 to fix it. Upon searching this information I found that this has happened to multiple people and Kia is not trying to fix it. I spent all of my savings on this car to be able to transport my family safely. This did not happen.
