2021 Kia Telluride

The problem first occurred at the end of May 2026. The digital instrument cluster completely stopped working while driving, cutting off all FMVSS 101 compliance indicators including the speedometer, fuel gauge, engine temperature, and RPMs. This problem has persisted on and off since May 2026. This is a huge safety concern because I am unable to determine my vehicle speed, etc. while driving. The issue occurs without warning and completely affects my ability to safely operate the vehicle. I took it to the Kia Stamford, CT dealer on June 5th and they were unable to replicate the problem saying when they turned the car on the instrument cluster was functioning normally. They said they "hard reset" it at that time. The very same day after leaving the dealership, the problem occurred again and has occurred intermittently ever since

Spontaneous shatter of sunroof. Danger to myself, passengers in the car, and others on the road. Insurance claim complete and the sunroof is now replaced/repaired No warning signs, no impacts prior or at the time of shattering. Glass puckered up as if pressure from the car caused the shatter rather than something external to the car.

My 2021 Kia Telluride has developed progressively worsening engine problems without any warning lights ever appearing that may present a serious safety concern. Approximately two months ago, the vehicle began experiencing significant engine shaking and rocking. Maintenance and repairs were performed, and the symptoms temporarily improved. The engine symptoms later returned. The vehicle began making a noticeable ticking noise that progressively became much louder and occurred both while idling and during acceleration. The vehicle subsequently shut off after being driven to an independent mechanic. Multiple warning/diagnostic alerts appeared, and the vehicle would not remain running when restarted. The mechanic checked the engine oil and found it essentially empty. Approximately 4½ quarts of oil were added. The ticking noise continued despite the addition of oil. Later that same day, the engine developed a pronounced knocking noise that continued while driving. There was also a hot smell, and I had noticed discolored smoke coming from the exhaust. The vehicle is currently parked and is available for inspection. I have stopped driving it because I am concerned about an engine failure and the possibility of the vehicle shutting off or losing power while being operated. The vehicle has been maintained and I have documentation of its maintenance and repair history. The underlying cause of the severe oil loss and engine symptoms has not been determined.

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.
