Tail light assembly is melting around the connector for the brake light bulb. The connector and bulb get so hot that surrounding plastic and connector plastic melt causing the brake light to fail and making replacement impossible. Hyundai replaced two melted brake light assemblies on the passenger side and one brake light assembly on the drivers side in less than 4 years. Now the driver side brake light assembly is melting again. This is a fire hazard and a safety hazard because the brake light stops working when the connector melts. Hyundai replaced two assemblies under warranty. I paid $250 for one brake light assembly and now Hyundai wants to charge me $250 for the fourth brake light assembly. This should be recalled by NHTSA. Googling the Hyundai 2011 brake like assembly list many other people with the same issue. This is a manufacturing defect that is causing a safety hazard for 2011 Hyundai drivers and other drivers that encounter cars with the failing brake light assembly.

Experienced issue with my Hyundai Sonata 2011 not starting and heard a clicking noise. Towed vehicle to local Hyundai dealership (where purchased). Service report on April 21,2015 indicated starter fork had failed. Cost of labor was $112.50 and plastic fork $8.13. Plus towing cost this is needs to be investigated for root cause and corrective actions. Per service department this was not covered under drivetrain warranty. This part should not be failing after only 77,213 miles. The long term reliability of this vehicle is a concern with rising and mounting labor cost. How long will this fork last" how did this part pass the Hyundai development and product validation automotive testing? or is this a manufacturing defect issue after release " this is another known issue that is being reported by Sonata 2011 owners and not being addressed it is poor when the towing service person knew what the issue was. As he has towed several Sonatas with same issue.

In mid--August 2015, my car began to have odd things happen such as the car alarm randomly going off. I replaced the battery thinking it may be the cause. That did not help. The alarm still randomly went off. I did not think this was a serious problem until my daughter was driving at highway speeds. On Aug 14th she reported to me that her steering became erratic regardless of what she did. After she pulled over, she noticed the fuel gauge went to zero and the low fuel light began blinking despite having recently filled the tank. When she got back on the road, the cruise control suddenly stopped working. Finally, within the next couple of days, the brake lights came on and would not go off. This caused the left tail light assembly to completely melt! then, on Aug 24th, she drove the car to O'brien Hyundai in ft myers, fl. They replaced the steering angle sensor, sending unit, brake switch, brake switch stopper, and tail light assembly. They could not tell her or me what the root cause was for this electrical issue that nearly caused a accident.

While driving on a highway in the middle of traffic my 2011 Sonata completely stopped and the engine totally seized up endangering my entire family. There was no unusual engine sound prior to it stopping and no warning whatsoever. We had to coast to the side of the road, avoiding oncoming traffic. This is totally unacceptable as it endangered 5 lives. Thank goodness we were able to get to the side of the road. We are told that the engine would need to be totally replaced at a min. Engine cost of $5800 not including labor or other parts. In estimating costs, probably $8000 or more. It looks like there is a defect in the rotating assembly that causes sudden and catastrophic engine failure. Hyundai is aware of this problem and has done nothing to prevent it. Now I have no car to drive, and must somehow come up with the above costs or rent a car. The car is out of warranty but was well maintained. This is a serious problem and needs immediate attention.

Intermittent flashing and blinking dashboard and exterior light while turn signal or wipers are engaged after this incident happens the battery is drained of power. Battery test full load and alternator test good. The battery is wearing down because of this malfunctioning electrical problem. Last night (8/21) something new happened. When I went to start the car I found it dead again; yet the " lights on" indicator light was visible on the dash buy the light switch was in the off position. I have others witness this crazy malfunction over the past 4 months and yet the Hyundai dealership cannot replicate the problem and therefore will not replace the combo switch (as diagnosed by my corner mechanic)
