The brake lights were staying on... simple fix, there is a rubber grommet on the brake pedal where it contacts the brake light switch. The grommet has worn, indented, and doesn't depress the switch in far enough to turn the lights off... new rubber grommet solves the problem...
Like others, the parking lights stay on instead of going off with the ignition. Headlights do go off.

Has anyone figured a fix for this, short of paying 600-700 dollars for the dealer to replace the fuse block?

Seems like a standard automotive relay, turned on by the accessory power, could be inserted in the parking light wire. When the ignition was off the parking lights would then go out. Of course the Hyundai dealers would lose their gravy train on fuse block replacements.
Parking lights stay on, even when switched off, key removed from ignition and doors locked.
Battery has drained several times. Currently must rotate light switch back and forth between Auto and Off positions, until I hear relay click off. Extremely annoying and may cause stranding with a dead battery. Not acceptable, and a safety issue. None of the fixes I've heard sound promisisng.
kept coming out of house to dead battery and parking lights on and I knew I hadnt turned them on, only having driven during day, didnt even turn them on, and later on in night noticed they were on... this has made me nuts, dead battery four times in two weeks, I thought I was going crazy, now I see they are coming on on their own, hen I didnt even turn them on. They should be doing a recall on this, its ridiculous. Now I bring charger with me everywhere, afraid of getting stranded.
Parking lights turn on by themselves, when the car is off and the light switch is in the "off" position. Has happened several times.
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."
Same situation as others report. I sit in the garage turning the switch on and off, after the engine is off and my key removed from the ignition. Sometimes I get lucky after turning the switch 25 or 30 times, but a few times they haven't turned off until 75 or 80 times. Doesn't seem to make a difference whether I've had the switch set to "auto" or to "on," or whether I turn off the engine first or try to turn off the lights first. HELP!
I have the same intermittent problem with the dashboard lights and parking lights not turning off once ignition is off. I brought it to the dealership when I first noticed, and of course they couldn't diagnose the problem as the car was intermittently working properly at the time. I'm at 92,000 miles on my car now, but learned that taking the first two fuses out of the box located at your knees on the driver side. This is only temporary fix for those who are draining their battery. When driving the car at night, remember to pop the fuses back in. I've been doing this until I found a solution rather than handing good money over to the dealership. I'm hoping the suggestion to switch out the fuse box will work... if I can find one for a couple hundred bucks, it's worth a try.
Same issue with my car. I sit for about 10 min. every night trying to get my lights to shut off otherwise I have to jump it in the morning. I have taken my car to the dealership several times and they were unable to diagnose the problem. Today, I was told it was the body control module so I looked it up and found that I am clearly not the only one. This needs to be a recall!
same problem and i just replaced the whole headlight assembly switch and it still fails to turn off a failed relay problem
ALERT !!!!!!!!!!!!!!!!
i fixed this problem by a fluke
the relay is the faulty component as noted above.
i had ordered led bulbs for my car earlier and when i installed them it fixed the relay issue.
reason might be that the relay is worn out that it can only handle less loads.
Park lights remain on after keys removed from the ignition. I'm going to try to leave auto lights off for a while and see if this helps.
Parking lights stay on even when turned off and key removed from ignition. The auto light function does not function properly. Have had to dealer 4 times and they say "do not know what the problem could be." I think they might find a solution when the warrenty is completly expired. I too think that a recall should be made on this problem for several reasons.
The headlights remain on after the car has been turned off. If I do not notice it at the time, I will come back to a car with a dead battery. The only way to get the lights to go off is to repeatedly turn the car on and off until the lights stay off. I have read some reports that if I change out the fuse box, then the problem will be solved. I am trying to find out if it is the fuse box, or if it is the bcm (body control module). My research so far indicates that the fuse box and the bcm are separate units in the 2007 sonata, but they are combined in later models. Any help with this would be appreciated.
Same issue as everyone above. Lights will not always turn off when you switch them off. Driving lights will stay on and have caused the battery to drain twice. Have jumped the car and ensured the lights were not on. The following day the battery was dead again. Took to the dealership and was told the BCM body control module has failed and it is going to cost me $600 to fix.

Honestly looking into fixing this myself, doesn't look to difficult and I wont give a dime to the dealership due to poor customer service, and completely rude attitudes from the shop manager, and the general manager.
this really pisses me off I bought the car used and it just now started doing this there with 25000 miles on the car and now I cannot cut my lights off unacceptable never would buy this car again
parking lights stay is possibly the cheapest car ever built.
so many issues with this vehicle due to cheap manufacturing practices.
i shoulda bought American !!!
