I called Hyundai regarding the brake lamp recall issue in my car. I have the same issue of my brake lamps. When you depress the brakes the lamps are always illuminated it only goes off when the car is turned off. This causes several people to mistake if I am braking or not. I have read several peoples complaints on the recall website, and all of us are told that " the recall has not affected your car" after giving them the VIN. Well I say it is. I have the very problem spoke of in the recall. Second the recall does not say the car must also be unable to come out of park. There are three separate issues. I want this car looked at how can several cars in different states have the same problem, with the same year car"??"

Emergency flashers on my 2004 Hyundai Sonata began flashing for no apparent reason and could not be turned off (ignition was off), this continued for 15-30 minutes from the time it was noticed (neighbors knocked at the door to report that the flashers had been left on). The occurrence repeated several times throughout the night and the next day. Accessing the vehicle using the keyless entry, the doors re-locked themselves, and this repeated each time I unlocked them. The flashers stopped when the door was open or the car was turned on, but when the door was opened there was a clicking noise in the dash (at the same rate as the flashers had been flashing). We took it to the dealer for repair and they said it is the emergency flasher 4-way switch (part #937903C000) -- which is on national back-order for one month! this part is apparently not covered on the gold plus protection plan!

Emergency flashers began flashing for no apparent reason and would not be turned off. Then trying to use the keyless entry door opener, the locks began locking and unlocking. When the car was running this stopped. We took it to the dealer and they replaced the etac module, then the entire fuse box. After returning home, the hazard lights again began flashing while the car was parked. This would stop and begin again intermittently. Returned to the dealer and left the car for several days. Finally a switch was replaced and the problem ceased.
