I got a 2025 Kona se and have had it for a month now. When someone sits in the backseat and buckles in, the car doesn’t register that they have their seat belt on. I took it back to the dealership two weeks ago, and they said it was working fine. But today, the same problem happened again. I’m not sure if I have a faulty vehicle or if others face this issue too.
I don’t know if this applies to you, but usually when this happens, it’s because someone leaves a bag or something on another seat. I found it frustrating until I figured out that it detects any object over a certain weight, like shopping bags or a laptop. So, when someone gets in, I tell them to leave their stuff on the floor or use all the seat belts, even if no one is sitting there.

It does let me know if I have stuff in the back when I turn off the car, but when I have a passenger on either side in the back, the alarm still goes off for the whole ride.

My Hyundai won’t keep the seat alarm going forever; it only lasts a few minutes.
My wife had a similar problem. When she would drop off our kid at school, the car would beep like there’s someone in the back seat. I think it might be related to the back door opening while the car is still in drive. I suggested she put it in park before opening the door. She hasn’t had that issue since, and I noticed it when I used the car too.
I had something like this happen, but it was with the center seat alarm. A passenger put their bag on the middle seat and that triggered the seat belt warning.
Check the buckle and make sure it’s clean. Also, ensure it’s engaging properly. If it happens again, take a video to show the techs at the service center.
Mine knows there’s a grocery bag on the seat. I would definitely take it back and point this out.
I rarely use my back seat for passengers or anything heavier than a jacket, so I haven’t noticed if there’s a problem.

That’s helpful!

Same here, but when I do have someone, the sensor doesn’t detect them being buckled in.
@Victor0
For me, the issue is when someone sits in the back seat on either side, the car seems to detect someone is also sitting in the middle. You can check this by looking at the display in the lower front console. The red lights show who is detected with their seat belts. My solution is to keep the central backseat belt always strapped in, even if nobody is sitting there.

The one time I did have a family member in the back seat, I didn’t experience any sensor problems.

Do you have a SE or a Limited model?

I’m not in the US, and we don’t have the SE trim; mine is similar to the Limited.
