“The alarm will sound randomly while driving or parked. We are not sure what is going on. It happens dozens of times a day and alarms my teenage driver. The button is not pushed, nothing is touching the car. Just random. We want this fixed because it is a safety concern, especially when she is driving and the alarm goes off for no reason.”

“My driver side sun visor flops down. It looks good, is not torn or appear abused, but it keeps flopping down when I drive and the angle blocks my view. I do not know why it happened, I simply tried to push it into the position that suits me best and some plastic fell from the end piece where it attaches to the frame. I was parked at the time, preparing to drive.”

“When car is placed in drive the gear shift display will show random gears. It will cycle through all the gears until you select to use the manual shift (+/-) to ensure that you are in the proper gear. This has been an issue on others car in the Sonata line up just not this year. This problem needs to be addressed and corrected. I am taking my vehicle to the car dealer today to get this problem fixed.”

“We bought a used 2009 Hyundai Sonata and after 9 months the navigatio system went blank. Very disappointed. It flashes th 33rd Hyundai logo followed by a blank white screen. Tryed rebooting. $100 just to find out what's wrong. Now we find out there were problems from the get go with tho s system. Very distracting and safety issue at night. We bought an extended plan which does not seem to cover navigation.”

“I started my car and as I started to turn the steering wheel so I could pull out of the parking space smoke spewed from my dashboard. I looked up under the dash and noticed the wiring harness in flames. I extinguished the fire. I then had the car towed to a Hyundai dealer. They examined the damage and said tat it would cost me $4000 to repair it as I needed a new wiring harness. …”
