The horn started sounding for no reason in our driveway. The Hyundai dealership confirmed that the horn switch in the drivers side airbag assembly is broken and in the closed position. The part cost is a ridiculous $1,000. All airbag assemblies in all the local wrecking yards also have broken horn switches. How can this be allowed" the horn is a very necessary safety device that should last the entire life of a vehicle. Why hasn't a recall notice been issued for this condition" [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

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!

The ac/heating electric [fan] control comes on when it wants to but will not activate when turned on. When taken to a mechanic on 3 occasions, it activates and remains on for days then stops and will not come on again. Mechanics do not want to work on it unless it does not work at all. Everyone wants to "investigate" and charge me accordingly but no one wants to tell me the actual problem. This had been going on for many months on my car, as well as other Hyundai models. The unresolved situation remains dangerous because of window fogging and lack of air flow through the vent system in the front and rear. Last winter a partially fogged window, while the fan was running, contributed to an accident during a very heavy rain storm.

Drove car 3 miles from point a to point B. it was parked at point B for approx 45 minutes. Then driven 300ft to point C. when I got out of the car, I smelled something unusual but I thought it was the auto shop next door. When I went into the store, an employee looked through the glass window and shouted "someone's car is on fire." I looked and saw it was my vehicle. There was smoke coming out of the hood. The car no longer starts. I will write again to update on diagnosis from Hyundai.
