2021 Kia Telluride

On Friday, October 16, 2026, while traveling approximately 70 mph on I-94 in Wisconsin, the smaller, operable sunroof above the front seats of our 2021 Kia Telluride suddenly exploded without warning. The sunroof was completely closed and flush with the roof, not tilted or vented. The sunshade was open, and the outside temperature was approximately 50–55 degrees. We heard an extremely loud bang resembling a gunshot. There was no apparent impact, no vehicles close enough ahead of us to have thrown debris onto the roof, and no bridge or overpass overhead that could have dropped an object onto the vehicle. The glass appeared to blow primarily upward and outward. When we stopped to inspect the vehicle, the remaining glass around the opening was turned upward. Glass fragments were scattered throughout the passenger compartment, including across all the seats and the floor. I have filed a complaint with Kia Corporate but the vehicle is in our driveway at the moment. I am waiting for further instructions from Kia. We were traveling with three passengers and a dog. We had to remove glass to protect everyone from injury and did not retain the fragments that fell inside the vehicle. As we slowed down and searched for a safe exit, several other motorists pulled alongside us and gestured to make sure we were all right so clearly it was visible from the outside. Fortunately, I maintained control of the vehicle. However, the sudden failure was extremely frightening and created a serious potential hazard at highway speed. A driver could easily be startled or distracted enough to lose control. I am concerned about a potential defect involving the front sunroof glass or its assembly, particularly given reports of similar incidents involving Kia Tellurides. I request that NHTSA document this incident and evaluate whether it may be part of a broader safety defect affecting these vehicles.

Alternator died and had to get replaced at 80,000 miles. Car died while driving on the highway. Had to pull over and get the car towed. Had to get the alternator replaced and paid out of pocket.

NHTSA Vehicle Safety Complaint – 2021 Kia Telluride I am the original owner of a 2021 Kia Telluride with approximately 78,000 miles. My vehicle has experienced recurring mechanical and drivability concerns, including an intermittent check-engine light, a previously reported camshaft-related diagnostic trouble code, and hesitation during acceleration. Of particular concern, there have been instances when I have pressed the accelerator pedal and the vehicle has hesitated before responding. This delayed acceleration creates a potential safety concern, particularly when entering traffic, merging, or navigating intersections where predictable engine response is essential. Additionally, the vehicle has exhibited rough operation while reversing and unusually harsh engine behavior when the automatic engine stop-start system engages. Despite multiple visits to a Kia-authorized dealership, including a monitored 1,000-mile oil consumption test, these concerns remain unresolved. The dealership advised that the vehicle passed the oil consumption test but subsequently recommended a dynamic engine cleaning procedure. I was informed that the technician was approximately 85% confident this procedure would resolve the issue. However, no definitive explanation of the underlying mechanical problem was provided. I have requested written documentation of the diagnostic findings and the basis for the recommended procedure. I have also opened a formal case with Kia America Consumer Affairs regarding these unresolved concerns. I am submitting this complaint because I am concerned that the recurring acceleration hesitation and related engine symptoms may indicate a safety-related defect that has not been adequately identified or resolved. I respectfully request that NHTSA document these concerns and evaluate whether similar complaints involving 2021 Kia Telluride vehicles indicate a broader safety issue.

NHTSA Recall Number 26V430000.

I was attempting to accelerate on the freeway and the rpms kept going up but it felt like the engine didn't want to shift gears. Suddenly the rpms shot all the way up and then dropped to nothing and I was forced to coast off the freeway, thankfully we were by an exit. The vehicle had zero power and we were unable to move it off the road, despite assistance from passersby. The wheels were locked in place and would not move until the tow truck driver showed up and looked something up online to manually force the car into neutral. (Though it was displayed as being in neutral) This is a 2021 vehicle bought brand new and has been properly maintained. Approximately 2-3 weeks before this, my husband randomly checked the oil and it was about 2qts low. It was filled and seemed to be running perfectly fine so we didn't give it another thought until this happened but now we're wondering if this particular engine is prone to the excessive oil consumption that has been noted in several other kia motors.

Vehicle was sitting all night and entered the garage in the morning and found the radiator fan at full speed. Car was not running, so backed it out, turned it off and the fan turned back on. Took it to a KIA dealer and kept it for a few days and just stated they couldn't duplicate the issue, although I couldn't get them to tell me technically what they checked. I kept the car parked outside for fear there might be an electrical issue and something overheats. Then was recently out and came out to my vehicle to find the fan running again. This time took multiple videos and it now consistently doing it. Took it home for the evening and disconnected the battery, and in the morning as soon as I reconnected the battery the fan started up to full speed again. Dropped it off to another KIA dealership and it was still doing it and showed it to the service advisor and gave him the videos. They are currently looking at it now. Also, there were never any warning lights or alarms that anything was wrong. There are so many postings out there on this issue on forums, FB, Telluride sites, etc., that I'm shocked there isn't at least a KIA TSB on this problem.

On September 4, 2026, my son was driving our 2021 Kia Telluride on the highway at approximately 70 mph with cruise control engaged when the vehicle suddenly began making a clicking noise, followed by a catastrophic engine failure. We observed no oil-pressure warning or other advance dashboard warning before the failure. The sudden failure at highway speed created a significant safety risk. I am the original owner. The vehicle had approximately 115,000 miles at the time of failure. Its most recent oil change was performed on June 4, 2026, at 112,613 miles, approximately 2,400 miles before the incident. The servicing Kia dealership reported that the engine had a hole in it and essentially no oil remaining. The oil filter and drain plug were in place, and the dealership reported no external oil leak that explained the missing oil. An oil-filter-housing leak had previously been repaired in January 2026. The cause of the oil loss and engine failure has not been conclusively established. I am concerned about possible excessive internal oil consumption and the absence of an advance warning before catastrophic failure. I request that NHTSA investigate whether this condition affects other Tellurides and creates a risk of sudden engine failure or loss of propulsion at highway speed. Kia denied my initial request for goodwill repair assistance. The case has been escalated, but remains unresolved. The vehicle and failed engine are available for inspection through the servicing dealership.

Unfortunately, beginning in June 2025, I experienced a serious engine problem. While driving, the vehicle began sputtering and stalled twice in traffic. I immediately brought it to the dealer, where I was told the engine had no oil, despite no prior warning of abnormal oil loss (no engine warning lights and no leaks). The service department added oil and initiated an Oil Consumption test. On October 4, 2025, the same problem occurred again. While driving, the Telluride began sputtering again, and the dealer again determined that the engine had no oil. I was charged for another oil change and instructed to complete another Oil Consumption test. During this process, the maintenance supervisor acknowledged that excessive oil consumption was a known and serious issue affecting Kia Tellurides and other models, and explained that engine replacement was the appropriate solution. I also observed another Telluride at the dealership undergoing the same type of engine repair. After completing the required testing, the dealer ultimately installed a rebuilt engine in my vehicle to address the excessive oil consumption problem with the original engine. I am now back in the same situation. On September 8, 2026, less than one year after the rebuilt engine was installed, my Telluride once again began sputtering while I was driving. I brought the vehicle to back to the dealer on on September 9, 2026. The service personnel again told me there was no oil in the vehicle, despite it being well within its recommended oil-change interval. More importantly, I was informed that the rebuilt engine currently installed in my vehicle is suspected of having the same excessive oil-consumption problem as the original engine. After following the instructions on yet another engine recheck and Oil Consumption test, I 've been told that the engine is burning oil at an exponential rate.

I purchased my 2021 Kia Telluride S new, with only 22 miles from the test drive. XXX (approx. 53,000 miles, vehicle age 18 months): The transmission failed while I was traveling approx. 75-80 mph on a major highway in [XXX]. Upon failure, the vehicle suddenly lurched as if the brakes had locked or the parking brake had been applied, nearly causing us to strike our heads on the dashboard and creating a hazardous situation for other traffic. After the failure, the vehicle would only operate in approx. first through third gears and reverse, and would not exceed 25 mph. We were forced to limp the vehicle off a busy six-lane highway. XXX: Due to parts delays, the vehicle was not returned until November 2022 after the transmission work. XXX (approx. four months later): The vehicle developed engine knock and excessive oil consumption. Advised this may have been related to oil degradation while the vehicle sat waiting for parts. Since then, I had to regularly check and add oil between oil changes. Despite low oil levels, no oil pressure warning light ever appeared. XXX (exact date unknown): While opening the sunroof at a stop, a loud crack occurred and pieces of the sunroof track, plastic and metal, fell onto me and my passenger. The glass is intact but became partially stuck open without the track to guide it. XXX: The engine knock worsened and became a squeal while driving approx. 60 mph. The vehicle lost power, requiring me to turn on hazards and coast off to avoid accident. Dealership mechanic advised that the engine had thrown a rod and blown the oil filter housing gasket. The vehicle is currently at the dealership and available for inspection. Kia has denied coverage despite the failure of a component linked to excessive oil loss and a recently extended 180,000-mile warranty, even after the engine threw a rod following a sudden loss of oil pressure. The failed transmission has likely already been disposed of. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The sunroof on vehicle is not able to open/close correctly due to track/clips broken. Vehicle was purchased used January 2023. The sunroof has been used less than 5 times during this period. I spoke to a service advisor at the local dealership, Bulldog Kia of Athens , Ga. He confirmed that there is a continual issue with this and that He advises customers to NOT use the sunroof after 60,000 miles. With further research, Kia is aware of this issue and has yet to offer a solution. The cost to repair is $6000.00 for a new sunroof. There is a kit that could be used by dealers to repair.

I have owned this vehicle since new. This vehicle has never had an accident. In the last 3 months the FCAS started sending messages to the dashboard without a vehicle in front, in clear blue skies and the radar element in front is clean. The message lasts 2-3 minutes and disappears. Went to Kia Service At Greenway Kia at the Avenues in Jacksonville, FL. The first time they said no errors codes popped up. They said it it happens again, bring it back. It kept on the same and I went back. No resolution. Then I sent and email to Kia Customer Service and after two weeks called them and the rep stated she found the email. She said take it to Kia Service which I did. Still the issue is unresolved. Made a second call to Kia Customer Service and spoke to another rep and she sent me to an agent "higher up?". He said that he will let the Kia dealership know. I was under the impression he would call them with the "fix". No luck. Why have they not changed the radar element in front? Money? I have driven vehicles for 62 years and never needed FACS. I guess car manufacturers installed this to deal with the current drivers paying attention to their social media accounts instead of driving. There is Kia Telluride Thread I found and several others describe the same issue. All report no solutions. Perhaps a recall only for those vehicles that have this problem. Respectfully,

My wife and I purchased a 2021 Kia Telluride brand new a few years ago when we lived in [XXX]. We are currently active duty USAF and brought our KIA Telluride with us here, while stationed in [XXX]. The vehicle is currently under two recalls SC316R and SC374 and is a fire risk. Under these types of recalls, vehicle shipping companies will not transport vehicles on their boats. We know this because we had to have two recalls (SC247F and SC243B) completed before we could have our vehicle shipped from the [XXX] to [XXX]. I am looking for assistance on how to have recalls and warranty service during our assignment here in [XXX]. We've reached out to Kia, opened 3 customer service cases, and have talked to them shortly to try to setup a repair. Then Kia stops communicating and ignores our calls and emails.

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

Every time the wiper blades are in intermittent mode they randomly stop at various spots on the windshield. I have to switch to low or high or turn them off completely for the motor to engage and work again.

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 70F 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.
