Check the deck lid latch to ensure the wire harness did not get pulled off somehow... That would be the only thing I can think could cause the boot ajar light to stay on.

The sensor/switch may have gone bad, disconnect switch wires and tape them together and see if it goes off.

My trunk latch won’t work on my 2017 Hyundai Sonata. I hear it click but it won’t pop open. The back seat unlock is inside the trunk!

The cable came loose in the truck. It is probably under warranty, the dealer will replace whole cable. If not, then look and you will see a bracket that the cable has come off of. Just push back in.

HOW TO TURN OFF THE TRUNK OPEN ALARM


The 2012 Camry's trunk lid has a 'trunk open' alarm that shows up on the instrument panel as 'door open' red icon. It also turns on the door open beeping sound so long as the trunk lid is open. This is normal and is usually not a problem..

However, if you should need to carry a large item in the trunk and can't close the lid, be prepared to listen to the incessant door open sound with no means to turn it off!!

The trunk lid alarm 'switch' is operated by the trunk latch when you open or close the lid. By manually operating the latch to it's closed position, you can temporarily silence the alarm.

Using a small screwdriver, you can easily press the actuator and turn the alarm off.

Picture 1: trunk lid latch in the OPEN (Alarm ON) position.

**WARNING**
YOU MUST RETURN THE ACTUATOR TO THE OPEN POSITION (ABOVE)
(ALARM ON) BEFORE YOU CLOSE THE LID. FAILURE TO DO SO MAY DAMAGE THE LATCHING MECHANISM
**WARNING**

DO THIS WITH THE TRUNK OPEN LEVER OR WITH THE REMOTE TRUNK OPEN BUTTON.

Picture 2: trunk lid latch in the CLOSED (Alarm OFF) position.

IF YOU TRY TO CLOSE THE LID WITH THE LATCH IN THIS POSITION YOU MAY DAMAGE OR BREAK THE LATCHING MECHANISM

Trunk struts need adjusting 2007 Sonata

Not if they are gas charged struts, but could be replaced. Take both struts off at one end and see if that was the problem with difficulty raising the trunk lid.

Trunk won't open

Lower the back seat and crawl into the trunk and see what the latch is doing when you activate the key fob. the trunk lid will have to be open to enable any repairs. Also an emergency release cable is probably visible (yellow handle) inside the trunk and will Open the trunk lid.

Check trunk lid warning light comes on even though it is closed

Hi there,

Most likely that the trunk switch has either moved (needs adjusting/tightening) or is faulty.

Have someone test the swicth terminals for continuity. Replace if faulty.

Cheers,

2007 Hyundai Sonata - Trunk is very hard to open

Is it stuck or just feel very heavy? If it is just feeling very heavy than the trunk struts need replacing. Your local part store might be helpful and install them for you if you purchase them there. If it feels like it is getting stuck on something the latch might need a little adjusting on the ring part. If this is the case then to adjust you usually loosen so it can move with little force but not too loose and open and shut trunk a few times and open one more time slowly and then tighten bolts being careful not to move latch. Hope this helps.
