2025 Kia Telluride

Multiple times while driving vehicle with shut off and light will flash on dash. Everytime take vehicle to deal to check always told that it can’t be duplicated everything is working. Started happen last summer and happen about 5 times since then. Last time it happen was in march took it to the dealer and they crash the car and still couldn’t figure out what causing it. Car been in the shop for about 3 months now.

The contact owns a 2025 Kia Telluride. The contact stated that on multiple occasions while driving at an undisclosed speed, the vehicle lost motive power with an EMS warning message displayed. The vehicle was able to restart after multiple attempts. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 25,000.

I lease a 2025 Kia Telluride. This vehicle has experienced three serious safety failures around the one year mark, all with young children in the car. Incident 1: accelerator failure and inability to shift gears approaching a freeway on-ramp — transmission was replaced. Incident 2: complete loss of steering control, brakes would not fully engage, and vehicle moved without accelerator input — dealership found nothing wrong and returned the vehicle with no explanation. Incident 3: accelerator failure and failure to shift in active traffic — another vehicle nearly rear-ended us — dealership said there was a belt loose that can cause issues sometimes. Kia Financial Services, as legal owner, has refused early lease termination despite these documented safety failures. The root cause of a loss-of-steering and brake-failure event has never been identified.

While driving about 35 MPH, the vehicle began to alarm and stated "the engine is off; pull over, put in park or neutral, and restart the car". I pulled over and found that the engine had indeed turned itself off in the middle of driving. When the engine turns off, both the braking vacuum system and the power steering go off, making it harder to brake and steer to safety. If I were going highway speeds, this would be a serious safety situation. I don't know exactly what caused the engine shut off, but it seems like a malfunction of the auto stop/start feature, which I had switched off during the incident (so the car should never turn off). The Kia website gives instructions on what to do in this situation [XXX] ), which would imply it is a known issue. There are forums of people reporting the same issue with 2025 Tellurides. My vehicle has not been inspected since the incident, but because it is electrical and there is no engine code, there is likely no evidence a mechanic could find. There were no warnings prior to or after the event. The vehicle has only 1650 miles on it. I expect it to happen again, and I will attempt to produce a video to document.

I am reporting multiple life-threatening safety defects with my 2025 Kia Telluride. The vehicle has experienced Sudden Unintended Acceleration, where it accelerates to excessive speeds without driver input. During these episodes, the braking system fails to respond, only allowing the vehicle to stop once its internal safety systems intervene. Additionally, the vehicle suffers from unpredictable stalling and power loss; the engine frequently shuts off upon parking—followed by the electrical system cycling back on without the motor—and the vehicle consistently struggles to start in the morning. These recurring mechanical and electrical failures pose an immediate danger to myself and others on the road.

Purchased a brand new 2025 Kia Telluride SX-Prestige X-Line on May 19, 2025. On or about December 20, 2025, my husband was driving (I was the passenger) in stop/start traffic when the engine shut off and the panel displayed “Put vehicle in Park or Neutral and Restart the Engine.” Since traffic was stopped, he put the vehicle in Park and restarted the engine. The vehicle started right up and we went on our way. However, on Saturday, January 10, 2026, the check engine light came on. I contacted the maintenance department at Buchanan Kia (where I purchased the vehicle). He asked if the vehicle was having any other issues. It was not, so we scheduled a maintenance appointment. I was told we could drive the vehicle, so we did. On our way home, doing 40 mph down, thankfully, a back road, the engine stopped, all systems shut down including steering/braking and the panel displayed “Put vehicle in Park or Neutral and Restart the Engine.” My husband was driving, he coasted the vehicle to a stop, put it in Park and the engine restarted. We were about 10 minutes from our house. In those 10 minutes, the engine shut off and displayed the message two more times. At this point the engine was running rough and would not idle. I again called the maintenance department and the vehicle was towed into the service department. The issue could not be replicated by the service department and we retook possession on February 3, 2026. I have sent a formal notice to Customer Care Center, Kia America, Inc. via certified mail, return receipt requested. I am filing this report as a precaution in the event something happens and someone is injured due to this malfunction.

While driving at highway speed and the adaptive cruise control engaged, the vehicle applied the brakes without driver input. The vehicle slowed gradually over several seconds even though there was no vehicle, pedestrian, or obstacle present in front of the vehicle. Road and environmental conditions were clear and normal, including clear weather, dry roadway, and unobstructed lane of travel. Traffic was flowing normally, and there was no lead vehicle. The driver was attentive and did not press the brake pedal. The braking occurred without any warning, alert, or collision indication and resulted in an unexpected reduction in speed, creating a risk of a rear-end collision from following traffic and on one occasion road rage (which has occurred due to this condition) as the driver thought I "brake checked" him. The vehicle has been inspected by the local Kia dealership (Spitzer Kia of Mansfield) and they could not replicate the condition. Kia has also been notified and a case number assigned (25773402) but with no resolution. This issue has occurred multiple times under similar highway driving conditions, indicating repeatable uncommanded braking behavior. Additionally, KIA issued a “Voluntary Service Campaign” for 2024 Kia Telluride’s on July 31, 2025 for the same vehicle behavior. Unexpected braking at highway speeds creates sudden speed differentials and increases the risk of rear-end collisions, even when deceleration is gradual. The driver has limited ability to anticipate or prevent the event. No warning lights, audible alerts, or collision warnings were displayed. CONCLUSION The vehicle exhibits repeatable false or uncommanded activation of the automatic braking system during highway driving, consistent with a potential defect in the AEB/FCA system. This condition poses a safety risk to vehicle occupants and surrounding traffic and should be reviewed by NHTSA
