Ioniq car alarm going nuts

[marley09]

Last night, my car alarm went off despite the fact that the door was closed. What could have caused this? How do I fix it?

It could be a problem with your 12V battery or a faulty sensor.

There could be a problem with your door switch. Did you take it to your dealer?

There could be several factors at play. If the doors were forced open or manipulated in any way other than using the key, it wouldn’t be surprising if the alarm went off. If you notice anything unusual, it’s a good idea to visit the dealer.
