My 2025 Kia Sportage Hybrid EX suddenly lost power, shifted into neutral on its own, and became unresponsive. The turn signals stopped functioning during the incident, which posed a significant safety risk since I needed to use the car’s inertia to pull over to avoid being rear ended at speed. The vehicle had less than 5,000 miles. I was in cruse control at about 70 mph. This is the second time that this has happened, the first about 6 weeks ago on Rte. 118 in Connecticut at slower speed, no cruse control. A diagnostic check at the dealer turned up nothing. They cannot report this incident to Kia Corporate unless it occurs while they are checking it out, an extremely unlikely event. Has anyone had a similar power issue?
 
I would post a complaint to Kia CS ASAP and get a ticket open to start tracking it. Make sure you mention that it happened more than once and include as many details as possible, like which dealer you took it to and their feedback. You're absolutely right that this is a serious safety issue. Sounds like a hybrid battery/drivetrain issue. KIA corporate seems to be pretty good about staying on top of issues like this:

Strange, I thought I saw this posted somewhere else recently... In any event, that's an extremely serious and dangerous situation, and a safety concern. I want to be very clear: what you experienced is not normal in any way. A vehicle should never lose power and shift into neutral on its own while you're in motion, especially at highway speeds.

The fact that this has happened to you twice with a vehicle that has less than 5,000 miles is a huge red flag. Your dealership's response that they can't report it to Kia Corporate unless it happens while they are checking it is completely unacceptable, in my opinion. They have a responsibility to report a serious safety issue, and the way I see it, they're putting your life and the lives of others at risk by not doing so.

You should contact Kia Corporate's customer service line directly. You need to bypass the dealership and report this incident yourself. Be very clear and firm about what happened. Explain that the car lost all power, the turn signals stopped working, and that you had to use its inertia to pull over. You should also tell them that the dealership is refusing to report the incident.

It's a serious electrical or computer issue, and it could be related to a faulty hybrid control module, a main computer, or a wiring harness. The fact that the diagnostic check turned up nothing is typical of an intermittent fault. A component can fail for a few seconds and then start working again, which would not leave a code.

You should also document everything. Write down the date, time, and location of both incidents. Get the name of the service manager you spoke with. This documentation will be very helpful when you talk to Kia Corporate.
