KIA Complaints

My 2025 Kia Telluride has experienced seven engine overheating events across three separate incidents, all under identical conditions: air conditioning on while climbing in altitude on Colorado mountain highways. Incident 1 (XXX: Driving from [XXX] to [XXX]. Engine temperature gauge reached H and the "Engine Overheated" warning displayed. Pulled over and allowed engine to cool. Vehicle taken to Kia dealership; diagnostics found no fault. Incident 2 (XXX): Driving to [XXX]. Vehicle overheated twice on the same trip. Dealership kept vehicle for multiple days; reported no issues found. Incident 3 (XXX): Driving to [XXX]. Vehicle overheated FOUR times during the trip, including in an area with no cellular reception. Occupants included an infant and a [XXX]. Had the engine failed completely, we would have been stranded with no ability to call for emergency assistance. The failure is consistent and reproducible in real-world conditions (sustained grade + AC load) but has not been reproduced by dealership diagnostics performed at the shop. No fault codes were reportedly stored. The pattern is consistent with a cooling system deficiency under high load (cooling fan circuit, condenser airflow, or thermostat), and similar complaints from other Telluride owners describe the same scenario with dealers unable to replicate. Safety concern: repeated loss of propulsion capability on steep mountain grades, risk of engine failure and stranding in remote areas without cell coverage, with young children aboard. Two dealer service visits have not resolved the defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Unknown it makes a ticking noise check engine light came on and oil isn't low. Recently bought it.

The transmission is not shifting gears correctly. The engine revs loudly and hesitates for a few seconds before shifting. There were no warning lamps. The vehicle has not been inspected yet. This causes a dangerous situation when driving and accelerating in traffic.

My vehicle has an active Supplemental Restraint System (SRS) airbag dashboard warning light. A professional diagnostic scan has confirmed the active fault code: B143100 - "SIDE AIRBAG REAR DRIVER RESISTANCE CIRCUIT SHORT TO GROUND This exact physical failure matches the known manufacturing defect detailed in NHTSA Campaign 23V-035 (Kia Recall Code SC262). While my specific VIN does not currently show up as part of the official recall population, the vehicle is suffering from the identical manufacturing defect and active short, resulting in a disabled passenger safety system.

Hello. I just started smelling gas fumes when my car has been running. I see no drips , etc. It happens everytime I drive it to the point where someone pointed it out to me. I had a new engine put in by KIA for my old engine "going to sleep" about 4 years ago. I have been told that this is a on going problem with the Model I have. I want to know what I should do at this point. Im [XXX] and [XXX] so I dont have the money to take it all over the place if this engine issue is covered. Could you please let me know and how to proceed? [XXX] [XXX] Cell [XXX] THANK YOU FOR ANY HELP ps....You should have record of KIA replacing the engine on file??? Is this a warranty issue since I do have a newer engine? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The airbag light randomly came on 2 weeks ago and stayed on , indicating that the airbags would not deploy in the event of an accident. I called my mechanic, who confirmed it was not a warranty item. My car only has about 45,000 miles on it and is well maintained. it has never been in an accident. I dropped my car off with my mechanic, who is waiting on the needed part, but noticed after I dropped it off that other Kia models have been subject to a recall for this same issue. My guess is that not a lot of people purchased Kia Cadenzas, so maybe this flew under the radar. I am looking at a repair bill in excess of $2,000 because of the cost of the part and the time it takes to access and diagnose the problem. Kia must be aware of this.

My engine has suffered a mechanical failure that makes the vehicle stall or lose power while driving, creating a massive highway safety hazard. Kia is using a software update loophole to deny fixing a physical, dangerous manufacturing defect.

2026 Kia Carnival Hybrid – Purchased 9/5/2025 Mileage: 8,450 April 2026- While driving over 60 mph, the vehicle's acceleration failed. A "Hybrid Failure" warning appeared on the dashboard, and the vehicle quickly decelerated. I had seconds to safely cross 3 lanes, and the vehicle had to be towed. The vehicle was at the dealership for 13 days, during which no problem codes were reported, and diagnostic scans appeared normal. No safety feature or diagnostic system reported this failure! I was told to take the vehicle because they had nothing to fix without a diagnostic report. May 2026- I drove the vehicle for a few weeks before this occurred again, with the same warning and complete deceleration. The vehicle was brought to a 2nd dealership, nearest to this incident. They have had the vehicle for 29 days with no safety or diagnostic issues to report and no ability to duplicate the problem. During this occurrence, my daughter was able to video the dashboard and deceleration from the passenger seat. I have provided this video to KIA. The national KIA team is refusing a buy-out option for this vehicle after my family and I have repeatedly been put in danger on the road. It also puts drivers around us in danger as we frantically attempt to proceed to safety while quickly decelerating. It is also extremely alarming that the safety systems and diagnostics do not show that these problems are occurring. While the local dealership has been understanding and professional to date; however, the National brand and its refusal to put safety first, especially on a brand-new vehicle, is unacceptable. We can provide the video and any other documentation you would like. We will be engaging with an attorney after Kia National declined our buyback

I am reporting a spontaneous sunroof glass failure involving my 2022 Kia Telluride. While driving at normal highway speed, I suddenly heard an extremely loud bang that sounded like an explosion or gunshot. I did not see or hear any object strike my vehicle before the incident. After safely pulling over, I discovered that the panoramic sunroof glass had shattered. The glass appeared to have blown upward and outward from the vehicle, and by the time I stopped, most of the glass was already gone. There was no prior damage, cracking, or warning that the sunroof was compromised. The failure occurred unexpectedly and created a significant safety hazard due to the loud noise, the potential for shattered glass to enter the passenger compartment. I had my 14 year old daughter with me. I man diagnosed with anxiety and ADHD and this had severely affected me because I was the driver and it occurred while operating the vehicle. Luckily, I had the shade closed, because that could’ve been really bad. At the time of the incident, the vehicle had approximately 91,000 miles. I am requesting that this incident be documented and evaluated as a potential safety defect, as I understand other Kia Telluride owners have reported similar spontaneous sunroof failures.

The contact owns a Chico Car Seat, Model Type: Fit 360, Model Number: 08087216240070, Manufactured Date: December 2025, and used in a 2025 Kia Carnival. The contact stated that the magnetic chest clip failed to remain closed as needed. The manufacturer was contacted and provided a replacement chest clip. The manufacturer stated that the chest clip operated as designed and was designed to come apart. The contact was concerned that the replacement chest clip was defective, and in the event of crash the car seat would not perform as intended. The contact requested a nonmagnetic chest clip from the manufacturer.
