The contact was repairing a 2009 Hyundai Sonata. While driving various speeds, the ignition would inadvertently restart while the vehicle was in motion. The starter motor could be heard re-engaging. The driver was able to drift to the side of the road, shifted the gear into neutral, and restarted the vehicle correctly. After several minutes of normal operation, the failure recurred. The vehicle was taken to an independent mechanic and then to a dealer where it was diagnosed that a new key cylinder and ignition switch needed to be installed. The vehicle was not repaired. The manufacturer was notified. The failure mileage was 48,000.

The contact owns a 2013 Hyundai Sonata. While driving approximately 40 mph, the gear shifter would independently move from drive to first gear, causing the vehicle to decelerate. The failure occurred on numerous occasions. The dealer was unable to diagnose the cause of the failure. The vehicle was repaired according to NHTSA campaign number: 14v434000 (power train). Also, when attempting to start the vehicle, the key became lodged in the ignition and failed to turn. The contact had to make several attempts before the vehicle restarted. Lastly, the front driver and passenger seat heaters would independently activate. The vehicle was not diagnosed or repaired. The manufacturer was unaware of the failures. The approximate failure mileage was 17,000.

2012 Hyundai Sonata. Consumer states concern with electronic ignition system and the lack of an engine kill switch. The consumer stated he had no way of shutting down the vehicle if the computer system accelerated or if he encountered a stuck gas pedal. The consumer wants to know, that he has a positive means of manually shutting down the vehicle in an emergency situation. The consumer would like a clear explanation of the push button engine star/stop switch. He would like to know is it a computer function or a manual electrical disconnect to the vehicle electronics. Also, if it is a computer function, will the dealer install a manual toggle switch under the dash that will kill all electrical power to the vehicle.

3x the driver window button is inoperable. Would turn off car and then it would again work. The worst issue is this: started up car this morning 7-9-12 (this is the 3rd occurrence) and the doors do not lock, then I put it in reverse and it goes about 2 feet and it applies the brakes. I noticed each time the the gear console does not light up. The car actually does not go into gear. Each time I have turned off the ignition and restarted it and it works fine. It's going to the shop for the 30k check up and this will be brought up. The drivers window has been brought up and the dealer has said there was no problem. Wrong. There is when it doesn't work. I had one of these in 2001 and it too had electrical issues. My neighbor just sold their 05 Sonata due to electrical issues.

After getting to work and putting the vehicle in park, when attempting to shut the vehicle off and retrieve the key, the key would only go to off and would not go to lock or let me pull the key from the ignition.
The key gets stuck in the ignition after turning off the car and won't come out. The car is in park, but the key won't turn completely off or come out.
Ignition key does not turn at all. Steering did not lock up initially, but when I tried to turn the key along with steering, it got locked. . . . Even after that steering would move a bit (not really stalled). Called aaa, couple of guys came over, tried to unlock the ignition by putting it in neutral and moving(shift override), but of no help. Called one of my friend who has a Hyundai Sonata as well, he said it happens often on his car. . . He tried for 10-15 mins. . . Got the magical combination of brake, steering and ignition key turns and it finally worked. Did a search on internet and apparently its not uncommon for Hyundai's at all. Hate to spend money for a design flaw from the manufacturer, especially as the car is only 5-6 years old.

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 car does not start. I enter the vehicle, put on my seatbelt, then depress the brake and the ignition button. The console will state "press brake to start engine". My foot is very firmly placed on the brake. This occurred intermittently but now occurs 50% of the time.

The 2005 Hyundai Sonata GLS has several problems that should be under warranty and recalled, close to the 2006 recalls. We own a company and have purchased over 12 to 14 Hyundais. We have found that the Sonata GLS 2005 has problems with the airbag deployment, seatbelt restraint, the front tires are closer to the back & not centered on the wheel well (has been this way since purchased, but they do not correct. ), have electrical problems & that unibody type frame & so on. In an accident where a truck left the tail gate down & a ladder hit the windshield, the car was then parked, turned off , the keys taking out of the ignition & then began looking for the cell phone then proceeded to open the door to get out infer all that the driver's side airbag deployed which also caused the front driver's seat belt to lock up & can not be pulled out to wear. Hyundai states that this is not warranted even though it was deployed after the accident occured. Hyundai had a great warranty 10 years ago. They do not stand up to their warranty as before & I have found that some of the warranty has changed. I have switched to Toyota. Hyundai has done nothing so far to correct.

My 2001 Hyundai Sonata was bought new. It has given me nothing but problems from the time I drove it off the lot and as soon as I hit the 60,000 mile mark (the bumper-to-bumper warranty ended at this point), the car constantly has something wrong with it. I have spent thousands of dollars in repairs. The airbags were fixed by the dealer because there was a problem. The brakes had a loud squeak and dealer replaced (under warranty at that time). The side front window motors have been fixed twice and now the passenger side window motor is broken and I had to put tape on it so that it will stay up. The timing belt went out after the warranty. Some kind of coil broke and needed replacement. The engine light is always turning on. I stopped taking it to the dealer after the car broke down, had it towed, dealer in laurel, MD claimed to have fixed it, charged me $768, picked up car, same problem, engine light still on and took it back to dealer. Dealer said there was yet another problem. They said they fixed it and they charged me over $500. Still the same problem. I took the car to a mechanic and was charged $45 for the repair. There have been several other problems that I have had to pay for repairs. I just spent $435 on another repair. Now, after each repair, I just wait for the engine light to turn on again for the next expensive repair and yet I'm still making car payments. Absolute worst car I have ever had.

While driving at about 35 mph the engine stalled then restarted while in motion. Then the vehicle started hesitating form a stand still and felt like it did not want to accelerate. I contacted the dealer and the following day they found a faulty cam sensor which they replaced. Two days later the vehicle started hesitating from a standstill and then started stalling when at a stop I. E. Red lights. I contacted the dealer on 6/28 and they checked the car the next day. They agreed with the hesitation problem and said the history code for the cam sensor failure had not been cleared. Seemed a little fishy to me. I asked if this would remedy the problem. The response was if it didn't give them another call. I said what if I am on the highway and it fails. The dealer said " call the road service number and have the car towed to them" that seemed to me to be a very short sighted view of a very dangerous condition. I cannot call if I am killed because the car stalls on the highway or it is in the middle of the night and I don't have a cell phone?. They designed, manufactured and warranted t the car. Seems to me it should be emcumbent on them to backup their warranty and not leave it to the risk of the consumer's life and limb until the car finally fails at a very inopportune moment. As an observation, this problem fits the description of NHTSA campaign id # 00v259000 which I complied with.
