2021 Kia Telluride Electrical System Problems

I have 2 issues going on with my vehicle. The trim on the outside of my doors is coming off which I know was a recall for some telluride vehicles about this old. Also ive been having some electrical issues/hot smell like something is burning if the heated seats get turned on.

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.

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.

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.

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.

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.

I recently brought this 2021 kia telluride used from a local dealership with 103,000 miles and everything was great , until yesterday i notice that when coming to a stop the car would sputter i thought maybe it was just a one off because i recently got recall work done at a kia dealership and they checked over the vehicle and everything was fine. so this morning im driving to work and it happens again so i check the oil and its completely empty i've went less than 3k miles on this oil change something needs to be done no warning to lights

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.

My engine started jerking when stopped. Then the electrical started acting up, like the windows wouldn't roll back up. Then the engine just shut off while I was driving.

Anytime going through the car wash the front and back parking sensors don’t work and gives an error. It is now permanently stuck with this error.

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.

Driver's side door will lose power while in park or while driving. This causes the locks to not work and windows (driver's and passenger's) will not go up or down. The mirrors will not fold in. Lights on the door goes out. Controls goes completely unresponsible.

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. )

Went to open sunroof and the plastic rail that Kia uses broke causing the sunroof glass to derail. Not able to retract the glass back in. In addition to the guide rail failing the wind deflector also broke.

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.

Harness and wires damaged and chewed by woodchuck causing multiple warning lights and malfunctions including headlight; turning signal and temperature to suddenly stop working, resulting in front wiring harness replacement and repairs costing over $7k in damage.

Here are some basic facts on what has happened: On August [XXX] 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. This safety recall came out on March 26th saying cars rolled away and they are updating software so cars do not move with car doors open. Kia is also stating there have been 16 cases not resulting in injuries. The Kia I had is a 2021 within this range and the VIN is [XXX] .

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!

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.
