Problem Reports

Same situation. The parking lights stay on even when i turn the lights off and open the door and leave. My battery has died several times because of this. I do check every time I leave the car but its hard to tell by the dash lights or car lights in bright daylight.

This should be a recall because it could well be a safety issue, involving the electrical system. a stuck relay could cause a fire.
Here is the fix i found but haven't done yet:

" I managed to convince a friend with identical Sonata to let me swap the driver side fuse box (part number: 91950-3K050).
I took his passenger compartment fuse box from his fully working Sonata and put it into my car. Indeed the problem went away and everything started working as it should.
The fuse box is located in front of the left knee of the driver, under the face panel and just above the lever for opening the engine lid.
It is not the easiest thing to remove, but not impossible and with some practice it can be done relatively quick. Once you pry out the center garnish (2 clips) you can easily remove the lower panel (4 screws and 4 clips). Then remove the metal plank (4 screws) to get easy access to the cable connectors. The fuse box holds to the chassis with 2 nuts and to a plastic cable holder with a screw. The screw face is towards the engine and is a pain getting a hold on the screwdriver.
Anyway, this fuse box indeed seems to be the problem. Now off to find one for less than the dealer price $385.60
I want to make a point that despite the fact the dealership service department tried to sell me a $800 part which would not solve my problem, saying it was a Engine compartment fuse box. Not True."

My 2007 Sonata has a problem with the parking lights and tail lights not turning off. In order to turn them off you have to switch the stem to off and then back to auto, this does not work all the time or fail all the time. You have to replace the cabin fuse panel assembly $650, this is the first real problem I have had with this car, it's just the price to repair is way out of line for a known problem.

Parking lights would not turn off. Like the others, I had to turn the light switch repeatedly, sometimes for 10 minutes, to get the lights off. Disconnecting and reconnecting the battery didn't work. This problem started immediately after the Hyundai dealer replaced the stop lamp switch under a recall. I had another garage replace the entire fuse panel for about $700 which solved the problem. I'm thinking of small claiming the dealer as they took no responsiblity for the problem but I have no proof they caused it.

The 2007 Sonata has a problem with the parking lights not turning off. In order to turn them off, sometimes it takes up to twenty times of turning the light switch on and off until they finally go out. This causes non-use of the auto light system, and dead batteries when forgetting to check if the lights actually turned off. According to my research the relayu for the control of the lights is integrated into the cabin fuse panel which costs around $750 for the part alone. Hyundai is not warranting this faulty fuse panel.
