2025 Kia Telluride Electrical System Problems

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.

The driver screen are all blacked out, when I start my car in the morning, cannot see the speed, fuel gauge and all ADAS functions not working. Car is only a month old with only around 430 miles.

The LCD instrument cluster above the steering wheel is all black and not turning on. The map screen to the right turns on, but not the odometer screen. Can’t tell how fast I’m going or how much gas is in the car. I’ve read this was an issue with the earlier models.

Rodent damage to floor harness of brand new car. Per service advisor this is a common issue with newer cars due to the use of soy based wiring which attracts rodents.

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

When I was driving in a parking lot on 10/03/25 my car displayed a warning light that my engine was off and I needed to shift to neutral or park. This occurred 2 other times. I was parked at a light on 10/10 and when we left dinner and turned at a light it also shut off. This is a huge safety concern and I have saw others reporting this same issue.
