    I opened my sunroof to let the heat out as we were getting back in after seeing a movie and the track popped and the sunroof glass was not broken, but not able to close because of the track. Kia dealership claimed not a warranty item and $7,000 to have fixed since it was the track that was faulty. Full mechanism needs replacing. Charged $250 for the diagnostic review and disabled the use of sunroof and moon roof until I pay to have the whole thing fixed. We were not driving when this happened. We were parked in a parking lot.

    After having a recall, performed on the emergency parking brake it would engage while parked, but when trying to put it in drive or reverse, it would not disengage this began happening approximately two weeks to one month after the recall was performed. It isn’t happening constantly, but it does happen often. On occasion, while driving, it will engage and pull the car to the side nearly pulling me off the road. After looking for other instances of this online, I came across a post that stated it happens to their car, but only when it was over a certain temperature. After watching more closely, I had figured out that it only happens above 70°F and it would only happen occasionally it was not every time it was above this . I have also brought it to the repair shop and they have no idea is what is causing it. I have found other postings about people having this issue with their Telluride same year. It is still occurring now and they are unsure of why or what is the cause.

    After receiving a Kia-issued transmission control module (TCM) software update, my 2021 Kia Telluride experienced a severe and dangerous transmission malfunction while descending a high mountain pass in Colorado. When I attempted to downshift for engine braking, 3rd gear completely disengaged, causing the vehicle to accelerate uncontrollably downhill. None of the lower gears would engage or hold as they had prior to the software update. This forced me to slam on the brakes and ride them continuously down the mountain, creating a serious loss-of-control hazard and risk of brake failure. Downshifting is essential for safe descent on steep grades, and the vehicle’s inability to do so created an extremely dangerous situation. The issue was duplicated by the Kia dealership technicians, and Kia field engineers have confirmed awareness of the problem. Despite this, Kia Corporate refuses to authorize transmission replacement or reversal of the software update, leaving the vehicle in an unsafe condition. This is a critical safety defect involving gear disengagement, loss of engine braking, unintended acceleration, and brake-dependent descent control. The vehicle is unsafe to operate on mountain roads, and Kia has declined to perform the necessary repairs.

    I had recall 26V430000 service performed at: Regal Kia [XXX] After the work was performed, both front power seats were inoperative. I was never informed by the service rep that the power seats were inoperative. I received a text of the multi-point inspection which included a quote for $546.87 for both front seat power switches. Never had the service rep discuss this with me while I was at Regal Kia, but reviewing my invoice at home I saw where the technician stated the power seats were inoperative after performing the recall SC374 service. The technician stated after following the applicable TSB for the recall they recommend replacement of both power seat switches at a cost of of $546.87 which Regal Kia wanted me to pay. It appears the TSB maybe doesn’t resolve the issue or perhaps a technician error during installation. I contacted Kia Customer Care ([XXX]) to see if I could have a local repair shop review the repair. They said only a dealership could do recall repairs. They recommended the next closest dealership in [XXX], but it is a one hour drive for me. They assigned case XXX and said they would contact Regal Kia and someone would call me back. I received no return call. I share the vehicle with my wife and she is now unable to adjust the driver seat to a comfortable and safe position. Why I was never informed prior to leaving Regal Kia is unacceptable as seat position is very important while driving. As both fronts seats were operative prior to the recall work, I don’t believe I should be responsible for the cost of new switches. As my power seats no longer work, I do not believe Regal Kia resolved the recall 26V430000 issue without cost to me. I would like to formally file a complaint against Regal KIA for not correcting the recall issue without cost to vehicle owner.

    Vehicle sunroof came off track on July 22, 2025. Possibly by the fault of the customer. Customer sought repair. Authorized Kia dealer recommended complete replacement of sunroof. On August 29, 2025, Customer paid authorized Kia dealer to replace sunroof with official Kia parts. On June 25, 2026, sunroof broke again through no fault of the customer. Wind deflector arms broke, got stuck open, and caused the glass to go off-track, rendering the sunroof inoperable and completely ruined. Took the vehicle to the same Kia dealer that repaired the sunroof originally. Even though the vehicle was within the 12 month warranty, it was over the 12,000 mile warranty, and Kia would not fix the sunroof. We opened a complaint with Kia Customer Care, and they did not resolve the issue for two months. Our claim was denied. We cannot afford to fix the sunroof again after 10 months, and if we do, we are concerned about it malfunctioning again. I am concerned that the sunroof glass could come dislodged while driving and strike another vehicle or cause a collision.

    I believe my engine to be defective and Commonwealth Kia to be neglegent in finding the defect dispite having been tasked to repair an issue while my car was under warranty. I first mentioned the problem on the XXX visit at $85,000 miles. Asked them to check the filters. Mentioned again at the XXX visit at 92,000 there is not documentation of the complaints on either of these visits but it does say ont eh XXX visit that the car "STILL LACKS POWER..." indicating that there have been previous discussions about the issue. The car was at 99,000+ miles at the XXX visit (still under warranty) I returned on XXX and XXX and was told on 1/20 that they FINALLY found the problem and that I would have to pay to have the entire engine replaced. I have since done some research and the issues that I am having are very similar to the Class Action Suit against Kia and the THETA II engine. [XXX] I have also seen on multilple owners boards on social media and in reports found on the internet that 2020-2023 Kia Tellurides have been having the same issues as THETA II engine models. [XXX] I find it difficult to believe Commonwealth Kia Service have not heard similar complaints nor have the ability to diagnose the problem on the first or second mention of the problem (which was while the car was still under warranty) I have called Kia USA who can not help me due to the fact that I am the second owner. The car was sold to me as "Certified Pre-Owned" by Kia. I believe Commonwealth Kia willfully misdiagnosed my problems so as to push the replacement cost to me and not the warranty INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    I purchased this 2021 Kia Telluride new and have had it routinely serviced and maintained by authorized Kia dealerships. At approximately 60,000–80,000 miles, the engine began consuming excessive oil. I reported the condition to the Kia dealer at approximately 80,000 miles, while the vehicle was still within Kia's 10-year/100,000-mile powertrain warranty. The dealer initially recommended a tune-up, but the oil consumption continued. During a later visit, the dealer identified an issue involving the OEM oil-filter housing and replaced the affected component. Despite this repair and continued maintenance, oil consumption progressively worsened. The vehicle now has approximately 160,000 miles and requires approximately one pint of oil every 2–3 weeks. The current diagnosis indicates potential internal engine damage, including cylinder-wall scoring that may allow oil to bypass the piston rings and burn in the combustion chambers. I have been advised the engine may require replacement at an estimated cost of approximately $13,000. My primary concern is that this condition began and was reported to Kia while the vehicle was still under the powertrain warranty, but the repairs did not correct it. Continued excessive oil consumption and internal engine damage create a safety concern because they could result in low oil pressure, engine seizure, stalling, or sudden loss of propulsion while driving. The vehicle is available for inspection, and its maintenance history, prior complaints, dealer repairs, and current condition are documented through Kia dealership service records.

    My 2021 Kia Telluride has suffered two consecutive component failures of the rear suspension's self-leveling shock absorbers. This component is the exact subject of Kia's August 15, 2024 Extended Warranty Program (WTY040), which acknowledges a widespread engineering defect causing premature rear shock failures. The factory-installed original shock failed previously. The official Kia genuine replacement part (redesigned by Kia to permanently address the original defect) has now failed prematurely under the exact same mechanical conditions. The failed replacement component bears a manufacturing date stamp of 11/2023. Kia America Corporate is utilizing an administrative loophole regarding the component's manufacturing date code to deny safety coverage, actively refusing to honor or remedy the failure of their own redesigned replacement part. The local Kia dealership service manager inspected the vehicle and formally endorsed 100% replacement coverage due to this premature safety failure, but Kia Corporate has completely stalled the repair (I have had a formal 100% goodwill coverage request submitted since 7/21/26 without resolution), leaving a known vehicle stability defect unaddressed on a public roadway.

    Sunroof broke when trying to open it. Now it’s in the open, venting, position unable to close. Dealership can’t look at it for a week so I’m risking water damage. Vehicle only has 31,000 miles on it and is just past the 5 yr warranty of course
