Hi all so recently my 2019 elantra gt n-line decided to go bonkers on me while the hood was open. Tracked the issue down to the plug to the hood sensor. Apparently at some pint it got so hot from the white wire it started to melt the plugs togeather ... so maybe check it out. Sure sign is the white wire begins to turn brown and your dash board lights up like mine in the video. I have to take the car to the dealer as its a fire hazard. Let me know if you notice the same issue and maybe we can hyundai to recall the sensor.

I fixed a similar problem on a ford escape. You can usually unplug the connector and by pass the sensor for now with a wire. The issue with the ford was the alarm going off randomly in the driveway since it though someone was breaking into the car (doors being locked, and the hood 'opening')

Hey, I don’t have the Elantra GT, I have the sedan in Limited trim but it started doing the same thing. This evening the alarm kept going off every couple minutes. I checked BlueLink and it thinks the hood is opening while the doors are locked. I sat with the car for a little bit and the dash would flash intermittently that the hood was open.

Yep would be the hood latch sensor. Mine was completly repalced but seems it did not fully repaiur the problem as it came back after a month same spot in my plug has burned out again.
I had the exact same issue with my 2018 Elantra GT hatchback. I ended up fixing mine. The issue can be (as long as the wires, and mechanical latch mechanism are in good condition and undamaged) the contact switch (this is what the hood sensor is) inside the hood latch. Its a contact switch worth about $2 at most. What I did is force down the hood latch in the closed position and then gently (and carefully!!) with a very thin flat screwdriver lifted up the flat metal piece (without breaking it) that contacts the switch in a better position. Afterward I just closed my hood and checked if the it sensed that the hood was in the closed position. Afterward I opened it up to see if it the switch still functioned properly and showed when it was open. Saved my self $400 at the mechanic.
