2021 KIA Telluride electrical problems

ELECTRICAL SYSTEM

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 code P0597. And at a later date the app detected a 2nd fault code P0598 which went away a couple days later.

ELECTRICAL SYSTEM

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.

Bought car on a Saturday (6-20-26)and that night noticed the drive mode was broke and the forward Collison is broke and will go on and off. Dealership said they did the whole inspection on the car before they put it on the lot to sell. Also, oil was extremely low when I left the lot and had to go back for an oil change. Took it to them on 6-22 to repair and have had to call to ask about my cars status when they said they would call me. Never would get an answer as to what was going on.

I own a 2021 Kia Telluride with approximately 111,000 miles. I initially brought the vehicle to a Kia dealership for an oil consumption issue and engine noise. The dealership diagnosed and repaired a timing chain and tensioner issue, stating the vehicle was “working properly” upon return. After picking up the vehicle, I immediately began experiencing electrical warning lights, including the battery warning light and system alerts (blind spot and general warning indicators). I returned to the dealership, where they performed diagnostic testing and indicated a potential alternator issue, but stated it was in a “borderline” range and that the vehicle was safe to drive. Shortly after leaving the dealership, while driving with my family in the vehicle, the electrical system began to fail. Multiple warning lights illuminated, and the vehicle lost electrical function while in motion. The vehicle ultimately became completely inoperable and shut down in a parking lot, creating a serious safety concern. Prior to the dealership visit and repairs, the vehicle had no history of electrical issues, warning lights, or charging system problems. The dealership later acknowledged that the alternator issue was not present when the vehicle was initially brought in. I am submitting this complaint due to the sudden and complete electrical system failure while driving, which posed a significant safety risk. The progression from no prior symptoms to total failure immediately following dealership service and diagnosis raises concerns about vehicle reliability and potential safety defects related to the charging system.

I am submitting this complaint regarding my 2021 Kia Telluride experiencing repeated and dangerous electronic system failures while driving. Kia of East Syracuse (NY) diagnosed the issue as related to the backup camera assembly and communication/network failures. While driving, the vehicle experienced loss of power steering assist, instrument cluster failure, speedometer malfunction, incorrect gear indication, backup camera activation while driving forward, blind spot warnings activating incorrectly, flashing/blank temperature display, and multiple driver assistance system failures. The speedometer displayed 0 mph while the vehicle was in motion and later displayed approximately 40 mph while stopped at a traffic light. The vehicle also became stuck in reverse while backing out of my driveway and would not shift properly, leaving the vehicle stopped in the roadway. Multiple safety systems malfunctioned simultaneously, including Blind Spot Collision Avoidance Assist, Lane Following Assist, Rear Cross Traffic Collision Avoidance Assist, Smart Cruise Control, Parking Distance Warning, and Forward Collision Warning systems. The dealership documented multiple fault codes and stated the dashboard lit up “like a Christmas tree” while the instrument cluster stopped functioning entirely. These failures create a serious safety risk because critical driving information and driver assistance systems become unreliable or inoperative while the vehicle is moving. The failures occur unexpectedly and without warning. Photos and video evidence have been retained, including video of the backup camera activating while driving forward and the speedometer malfunctioning while the vehicle was in motion. I am asking NHTSA investigate these failures as a potential safety defect involving the camera system, instrument cluster communication systems, and CAN network communication failures in the Kia Telluride.

There rear parking sensors have come up with an error message. After I looked into this it looks like a wide spread problem. The Kia Dealership said it was the rear bumper harness was faulty. I am just outside of warranty and Kia is trying to charge $850 for a problem that they are well aware of and are not addressing. They are also claiming that the oil filter housing is damaged and I have only ever gone to a Kia dealership for oil changes. After researching, this also appears to be a widespread issue which they are trying to charge $450 for. These 2 issues are known defects and widely reported and Kia should be fixing these items.

ELECTRICAL SYSTEM

Cooling fans running continuously after the car is turned off, which drains the battery. The dealership has identified that this is due to a faulty fan relay that will need to be completely replaced. The battery has been replaced once and the issue continued indicating that it was not a battery issue. The car ran out of battery in a busy location and caused risk to the passengers that were then exposed to busy traffic. The car has been inspected by repair specialists at the Vaden Hyundai Service Center. There were no warning lamps, messages or other symptoms before the problem began.

After owning this Telluride for a year the engine started stalling. I took it into the nearest Oil change company, and they informed me that the oil was completely out and dry. I always stay up to date with my oil changes, so this was a huge shock. There was no light that ever came on stating an oil concern and there was no light that came on even when the engine stalled. This company sent me directly to Kia stating they have seen this several times with this vehicle and they have oil consumption issues. I went to Kia and they had me do the oil consumption test. When completed they stated I was within the "standard" oil consumption levels. I asked why the car didn't even have an oil light or engine light come on as a warning and they had no answers for me. Had a light come on I would've taken it to be looked at prior to having the engine stall on me which was a major safety issue. Fast forward, I ended up and purchased another car and gave the Telluride to my husband. I drive a lot for work and he doesn't, so it made more sense to help with the oil. We are now having to put at least 3 quarts of oil in it in between oil changes. And he has still experienced the engine puttering. Both times with our kids in the car, steering becomes difficult and he has to pull off the road. Once he turns it off and restarts, it seems to be fine. Another mechanic told us that they anticipate a recall to come out with the 2021 Telluride soon since they have already recalled previous years for the same issues. It is absurd to have to put in 3 quarts of oil in between oil changes. The fact that no warning lights have ever come on is safety concern. The car randomly stalling is a safety concern. Kia needs to do something about this before someone gets injured.

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. Sounds like a scam to get another 5,000 dollars out of their customers. Won't be buying a Kia again.

I am reporting a serious and ongoing electrical and transmission issue with my 2021 Kia Telluride (VIN: [XXX] ). The problem began under 20,000 miles and has continued intermittently for years, progressively worsening. My vehicle is currently at ~99,600 miles and under extended warranty. The key safety concerns include: Transmission Lockout: The vehicle intermittently becomes stuck in Park and will not shift, even with the brake depressed. No-Start Condition: The vehicle will randomly become completely unresponsive—no dash lights, no infotainment, and no engine start. Electrical System Failure While Driving: Multiple safety systems fail mid-drive, including: Loss of power steering and air conditioning Random activation of ESC, TPMS, Collision Assist, Blind Spot, and Parking Brake warnings Infotainment screen turns off while in motion Component Failures Due to Electrical Shorts: Both the radio and the backup camera were diagnosed with shorts and had to be replaced under warranty. Brake Lockout Post-Shutdown: The brake pedal becomes very firm and the vehicle will not restart until hours later. Most concerning, my wife and children have been left stranded in the disabled vehicle on multiple occasions due to these issues. The car has been in the shop several times — around 50,000 and 80,000 miles — but no permanent resolution has been found. This is a clear and escalating safety hazard. The failures affect critical systems while driving and leave the vehicle unpredictably disabled. Kia has been made aware and an escalation is underway, but I am filing this report to ensure the NHTSA is aware of the pattern and potential danger these failures pose to others.

Child Safety Lock Failure. At random times something within the rear doors will make a constant clicking noise for roughly 20 seconds. When clicking stops the dash will display child safety lock failure. The clicking noise sounds as though it is coming from an electrical component such as an actuator or solenoid.

My main screen on my 2021 Telluride goes out suddenly, turning off the backup camera and collision warnings. Sometimes when I start the car it never turns on, sometimes it starts to boot and then goes out and sometimes it works for a few seconds/minutes and then turns off. Once and a while it turns on and stays on for days before going on randomly again.

My infotainment/navigation system has failed before the 4 year anniversary of my car 1/13/21. The screen freezes with larger vertical magenta colored blocks in the foreground with an olive green and brown background. Sometimes the screen is completely black. The color on the screen often oscillates between blue and regular functionality. When the system temporarily worked, I updated the software. Yet updating the software did not correct the chronic, safety issues with the screen. This very flawed Kia Telluride 2021 infotainment system presents a real safety hazard to every driver who has purchased this car. Today I am in Capitol Kia replacing a 3 year old infotainment system on my own dime. I counted there should be a class action suit and a recall.

Sunroof started to open and came off track and bent the tracking system beyond repair. Sunroof stuck in half open position and tilted or wedged in open position. Concern that it would fly off when driving and could not shut it to protect the interior in case of rain. There has already been a recall on the Kia Sorento sunroof moving tracking system in the recent past. This should be taken into consideration to have this be a recall on the Kia Telluride.

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. (I can't get my images of the 2 page dealer invoice for Cluster Assembly-Instrument $2600 that did not solve the problem to download on this form. )

The sun roof has only be used several times during the year. The sun roof plastic mechanism parts are broken. This causes the sun roof to be unable to close. With the sun roof slightly open and unable to close, my fear is that it may flip open in the highway and hit another car behind me. The car has been brought to the dealership to inspect and it will cost over $5,000 dollars to fix and replace the whole sun roof assembly. I feel this is a manufacturer defect as many other Telluride owners are having the same sun roof issue. There were no warnings or symptoms prior to this issue.

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. Also, the mirror function on my vehicle where the side mirrors fold/unfold when locking/unlocking the vehicle, the mirror(s) don’t fold/unfold every time I press the lock/unlock button on m key fob. Another issue, my windows don’t roll/unroll when I try to use that function. I can sometimes roll the front window up/down while the rest of the windows won’t roll up/down. I then have to shut my vehicle off, open the driver door, then turn the vehicle back on. Sometimes the windows will work, sometimes they won’t. It’s an ongoing issue.

Well, what I thought to be a solid build has succumbed to the known issues with this vehicle. The car has 17,7862 miles on it. I always follow the ‘severe’ maintenance schedule along with babying the heck out of it. I was driving the vehicle on city street, roughly 35-40mph when I got the Xmas tree of death light up on the dashboard (all the indicators went crazy), and a slight loss of power with engine and transmission. I shifted the gear shifter into manual so I could at least control the car and make it safely back home. Once I parked, I shut off the car and then turned it back on. The indicator lights turned off, however the check engine light stayed on. I swapped out the battery for a new one and that fixed the problem for a few hours until later that day the same thing happened again. At this point I know there is something more happening electronically that is not right. Hence the problem: The UB module assembly behind the dashboard needs to be replaced because it is defective (full disclosure, this is what I believe to be the issue, but will be scheduling appointment with dealer to have them look). Ah, but thank goodness for the Telluride forum that has brought to my attention many issues that I also experience with my vehicle. I too have a crack in my windshield that happened three months in (thankfully I have a film on the windshield that has kept it from spidering), I too have to hand wash or touchless wash car due to nightfall trim peeling (thankfully I have car ceramic coated so hopefully that is helping the longevity), I too feel the binding and slipping in my AWD system as I try to accelerate a turn from a stop. It would behoove Kia to address the ongoing issues with their ‘top selling SUV’ as clearly there are still many vehicles popping up with problems. I will say pay attention to the warning signs. Roughly a month ago, the forward parking sensors failed due to ‘blockage’. I should’ve known it would lead to a larger problem. This could’ve been bad!

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. In addition, the fuel performance reset to zero. She turned off the vehicle, and we could not reproduce the issue. From a safety perspective, this was very unnerving as it involved our children in our car, but also that the car started on its own after five minutes. If we were not at home and the car could have been running in the garage without our involvement. All regular maintenance and satisfaction of recalls had been completed by a Kia-authorized dealership before this event.

While at a red light after exiting the highway, the vehicle lost all power and functionality. The car was in drive, and the brake was pressed in. No buttons had been pressed to shut down the vehicle. I had no power and no ability to restart the vehicle. I placed the vehicle into park and attempted to turn on my hazard lights. Unfortunately, there was no response from the vehicle, and though I was interrupting traffic, I could not provide any visual indicators to oncoming traffic. After moving the vehicle into park, I was unable to move the car into neutral. After approximately five minutes, without the brake being pressed or any button is pressed, the vehicle turned on its own. I was able to move the car into drive and continue to function as expected. Prior to this, I had used the vehicle to drop off my kids at daycare (which required turning on the vehicle, driving, and turning off the vehicle). This event occurred roughly 40 minutes after a mix of highway and city driving. From a safety perspective, this was very concerning as I had no way to indicate to other drivers that my car was not driveable. Fortunately my children were no longer in the car. I was very concerned that not only the car lost all power and functionality, but was more concerned that the car started on its own. I was also concerned that if I had not moved the car to park and somehow it turned back on if left in drive what potential damage could have been done to me, another vehicle and potential injury 30K service and all recalls had been satisfied prior to this by an authorized Kia dealership.
