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)

My 2025 Kia Telluride is suddenly shutting off in traffic. It first happened 6/24/26 I was pulling away from a stop light when my vehicle shut off. I received a red dash as you would for collision warning and a message to shift into park or neutral to restart the vehicle, I tried to restart it started but without RPM's then would not restart my husband had to push the vehicle off of the roadway. I then tried to restart it again it started and shut off in less than 20 feet. I had it towed to the dealership after keeping it 1 week they say they can not recreate the problem. I picked up my vehicle yesterday and it again shut off before I made it 2 miles down the road, I had stopped at a stop light to make a left turn accelerated to make to my turn and the vehicle again shut off I coasted into a parking lot was able to restart it and drove it back to the dealership. The vehicle is currently with them. The vehicle had no warning lights prior to this happening everything was fine in fact when the vehicle shuts off the radio and Air Conditioner stay running like nothing happened. I have searched the internet and found many others having this issue with their dealerships also saying they can't recreate the problem.

The contact owns a 2025 Kia Telluride. The contact stated that while driving at an undisclosed speed, there was a loud sound coming from the sunroof glass before the glass shattered. There was no impact on the sunroof glass to cause the failure. Small glass fragments fell into the second and third row seats. The vehicle was taken to the dealer; however, the vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 22,000.

While braking in slow traffic at about 11-15 mph, the vehicle hit a pothole/road irregularity and the ABS appeared to activate. The brake pedal vibrated, but the steering wheel also began shaking rapidly left and right. Braking effectiveness was greatly reduced. Even with firm brake pressure, the vehicle did not slow as expected and continued toward stopped traffic ahead. The brake pedal pushed back against my foot. I tried to steer around the vehicle in front of me, but the steering wheel vibration interfered with my steering input and made the vehicle difficult to control. A rear-end collision was avoided only after I shifted the transmission into Park, which brought the vehicle to a stop. All driver assistance systems were off, including adaptive cruise, lane keeping, highway driving assist, and steering assist. This occurred during normal low-speed braking, not aggressive or high-speed driving. I have had similar but less severe ABS behavior before when braking over potholes, bridge joints, or rough pavement, with excessive ABS activation and reduced braking performance. Dashcam footage is available showing the pothole/road irregularity, vehicle speed, steering/hand vibration, my avoidance attempt, and the near-collision. This appears to involve unexpected ABS activation, reduced braking effectiveness, and steering interference during routine low-speed braking, creating a serious safety hazard.

I am the owner of a 2025 KIA Telluride. The engine shuts completely off with a Warming stating "Engine OFF! Shift to P or N, then restart engine". Car has no power and creates a dangerous situation in traffic. You are on a highway and you have to stop the car to restart. The traffic flow is dangerously interrupted. This issue happens randomly on it's own time and the reason is still unknown. The dealership usually cannot duplicate this Warning and several 2025 Tellurides are experiencing this dangerous condition.
