Selected complaints filed with NHTSA by 2021 Kia Telluride owners, lightly cleaned up (personal details are redacted by NHTSA).

My wife had placed our two children in the car in their car seats. She attempted to start the vehicle by pressing the brake and the starter button. Though all the dome lights and other normal electrical items were on at the time, as soon as she attempted to start the car, it instantly went dead. There was no power to anything, and all the interior dome lights did not work. No matter how often she attempted, she could not start the vehicle, even with accessory mode. It was almost as if the battery had been suddenly removed from the vehicle. At no point was the car moved outside of park. My wife removed our two kids from the vehicle, and shortly after, they were secured in our other vehicle; without my wife being in the Telluride, the car turned on itself. All interior lights were on, and the car was functional. She found that while the radio was on, the HVAC that had been on was now off. …

As I was driving down the highway in the rain, my check engine light came on and I was unable to accelerate my vehicle over 30mph and the speedometer stopped working. I was turning onto the road I live on, so I was able to make it home. I then shut my car off and turned it back on about 5 minutes later, and that issue was no longer happening. I had an upcoming appointment for an oil change at a Kia dealership, so I told the dealership about the issue. They told me that they hooked their computer up to the car and it was showing that there weren't any issues showing and the only way that they would be able to see that there was an issue is if the vehicle was brought in while it was malfunctioning. …

Here are some basic facts on what has happened: On August [redacted] I was in my driveway, in Mt Pleasant, SC, when my car rolled down my driveway with my two kiddos inside, resulting in me reacting and getting knocked over by the driver side door and the car running over my chest. I had 5 broken ribs, 4 are now titanium, several broken bones, a punctured lung and a torn acl. There is a police report but do not have to upload right now This was reported and Kia had my car for about a month to investigate it and gave us a very brief response stating "After the preliminary investigation results indicate that the vehicle functioned as intended, no issues found with the parking mechanism." Because of the trauma this has caused me, I made my husband make the car disappear and he sold it to a local CarMax in Charleston. …

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. …

The child safety locks will randomly start latching and unlatching until the button is disengaged. I have videos of it and the dealership has been able to reproduce the issue multiple times. If the button is not on, the issue does not occur. This is a problem since I have a 3 year old and he has had opened the door while I drive on at least 1 occasion. The issue began October 2021, I took it in for service in December and had to wait for the replacement part until almost March. At this point I have taken the car in for service 6 times for the exact same issue, they have replaced multiple components, actuator, master key lock system, etc. The issue will be fixed temporarily but will then reappear within as little as a day to a week or two. There are multiple reports of this happening on Kia forums and the issue is not model specific. …

I attempted to use my sunroof today 2/18/26 and I heard a popping sound and it sounded like something broke. I rolled the sunroof back closed and now the back of the sunroof (moonroof) is now propped open and won't close. I have tried the manual overide for 10 to 15 seconds and it just makes a clicking sound. I am pretty upset as I have only used my sunroof maybe 10 times in the 4 years I have had the car. After research there is a TSB 319 that clearly documents it is a known problem on 2019 to 2022 Telluride models yet, no recall. While it is not a major safety issue, it is now a concern that when it rains, it will get into my my vehicle causing further damage. This should be a covered repair on Kia's behalf especially when it seems it is happening most often after factory warranty or 60,000 miles for most who are reporting it. …

The alternator fails causing the battery to drain and die while driving and permanently kills the battery. When this occurs all power is lost to the vehicle and in rapid succession multiple warning lights illuminate and a cascading series of messages related to the vehicle saftey features appear one after another. While the engine remains on power steering, headlights, and all other saftey features shut off in rapid succession causing unsafe driving conditions and leaves the vehicle inoperable. The vehicle was towed to a local kia dealer that refused to diagnose the alternator problem until I agreed to pay $350 for a new battery and a $150 diagnostic fee. …

While driving the Kia Telluride, the forward collision avoidance warnings started flashing, then said it was failing, then the tire pressure system did the same, then the speedometer and tachometer failed as did the turn signals, gear shift, and lights. The car was becoming unsafe to drive. The car has been at the dealer for 3 weeks now, the dealer changed the Cluster Assembly-Instrument at at cost of $2600. Within 1/2 of leaving the dealership the same problem noted above began happening, again making the car unsafe to drive. In researching on line at the KiaTelluride forum there have been a large number of similar unsafe occurrences by other Kia Tellurides as reported by owners. This is a serious safety problem that has been noted numerous times. …

What happened: The analog speedometer and digital speedometer were not working. I was driving the car and I would be moving but my speedometer and digital readout remained at 0 mph even with my RPM showing as moving. All other gages and read outs were working except for speed. Safety risk for myself and others: I was unaware of how fast I was driving Problem also happened once prior a few weeks ago I put the car into Park and put back into Drive and it fixed it. This time however when I tried that it did not fix the issue. I even tried turning the car off and back on and it did not fix the issue. The issue was fixed after waiting until the next day to drive and when I got in to drive it worked again. Unable to repeat the issue as it is happening sporadically and does not seem to have a specific cause. …

While in drive, the battery discharge warning was displayed inconsistently, similar to what had occurred sporadically on January 21 and January 23. Without notice, multiple indicator lights started flashing, including low tire pressure, Safety features such as check forward collision assist system, and more. Power steering failed, and ultimately had to coast into a safe location. This resulted in a tow to the dealership, where after multiple days, the dealership found that the alternator failed and replaced it under warranty. This could have negatively impacted not only my safety but the safety of others as the vehicle safety features were not operational and I lost full functionality of the vehicle such as power steering loss. All regular maintenance and satisfaction of recalls had been completed by a Kia-authorized dealership before this event.
