2021 Kia Telluride electrical system problems

“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.”

“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”

“While driving this vehicle in route to Philadelphia airport JFK, i experienced a total malfunction of the instrument cluster. All of the warning lights continued to go on and off and were illuminating on the cluster non stop along with a audible chiming, all of wich lasted the 3 hour trip. The car is available anytime. Warning lights/alarms were not only distracting but affected the spedometer which would shut down totally. No dealer or service center has been contacted yet.”

“CATASTROPHIC FAILURE TIMELINE (13 DAYS) XXX: Delivery taken at 105,439 miles.XXX: My boyfriend noticed a cloud of smoke from exhaust as I pressed the accelerator pedal to leave the parking lot. I didn't notice because it was almost dark outside when leaving. He didn't notice again so he didn't stop me and told me when we got home. XXX (Day 12): Check Engine Light (CEL) on. Dipstick found dry. 2 quarts of oil purchased and added. Which brought the level right above the L line. Sent texts to both salesmen (Freedom and Driveway). Went to work in [XXX]. XXX (Day 13): Got home with Odometer: 106,974. Plugged Code reader into the vehicle and got Code P0597 logged at 1:04 AM. Tried both salesmen again through texts, email and or call. Have yet to get a reply from either. XXX posted review updates on both of my previous posted reviews for Freedom and Driveway. Received my first response from the Driveway review team only. XXX rear brake pads had been cutting into rotors a few days prior. I had to purchase a tool and pads to replace. XXX Documented loss of an additional 4 quarts of oil across 4 dates. XXX subscribed to Kia connect and the app also detected issue fault…”

“The Telluride was parked in my driveway on a hill. When the car was started by pushing the ignition all of the lights on the dash panel started flashing. The car was shifted into reverse to back down the driveway however the brakes didn’t work. We captured this on video via CCTV footage. You can see the vehicle reversing and the brake lights are on as the pedal was pushed but not responding. As the vehicle went on to a lesser slope it slowed some but was about to crash into my neighbors home when the parking brake button was pushed and the vehicle came to a stop. The evening prior when starting the car on a flat surface the lights all flashed upon starting but the vehicle had operated normally.”
