9 Gasoline Fuel System problem

Failure Date: 08/31/2011

Loss of power, car shuts down, 'check charging system' alarm/chime with alarm symbols on dash display for battery, check engine and wrench icons. Have to pull off the highway somehow (in midst of heavy traffic) to shut car completely off and restart. On third incident (one day after second), car would not restart for 10 minutes and check engine icon remained lit. Every incident has been while traveling at high rate of speed in commuter highway traffic. Very frightening and dangerous experience for driver and safety hazard to others when it occurs.

10 Gasoline Fuel System problem

Failure Date: 08/26/2011

The vehicle (2011 Hyundai Sonata 2. 0t) leaks gas at the rear of the vehicle after fill up. This can continue after 2 bars removed off from fuel gauge. It has leaked in the garage, which inturn has got gas fumes in the house. There is also an extremely strong odor of gas in the cabin. We have to drive with the windows down to clear the fumes. This is an extremely dangerous situation that the Hyundai dealership is not taking serious. Will it take an explosion for someone to do something about the problem. I have read numerous complaints about similar issues. This needs to be investigated before someone is hurt. This problem happens every time that we fill up the car. The vehicle has been into the dealership 3 times for this complaint.

11 Gasoline Fuel System problem

Failure Date: 04/08/2011

There is a smell of gas/engine fumes notable in the vehicle on occasion. The problem does not happen consistently, however there are some common factors to when the smell in noticeable. These factors include: 1) the engine must be hot, generally having been driven for at least 15 minutes or more. The smell is never noticeable when the engine is cold, such as after sitting overnight. 2) the vehicle must be either moving at very slow speeds of <25 m. P. H. , or sitting still. Examples would include driving through parking lots, sitting at an idle for a long period at a stop light, when first starting the vehicle after sitting in a parking lot for awhile, etc. 3) when the gas / fume smell is notable with greatest intensity, it seems to occur after a hot engine soak of 15~45 minutes at ambient temperatures of 30 degrees fahrenheit or above and in conditions of moderate- to high-humidity. Examples include during periods of heavy fog, rainy days, snowstorms, etc. On occasion, the smell is strong enough that it is no longer comfortable to remain in the vehicle. Rolling down a window at speeds >25 m. P. H. To clear out the cabin air, followed by activating the hvac recirculation button will lessens immediate recurrence the smell to some extent. Finding ways to "mask" the smell are of lesser concern than determining why the smell exists in the first place. The vehicle has been in for this concern twice, with neither trip to the service bay having resolved the concern. While it does not appear to be an issue causing immediate danger (no noticeable fuel leaks or signs of fire), the smell of gas and engine fumes entering the passenger cabin is a bit concerning, both from a potential fire hazard in the future, and/or exposure to carbon dioxide and other noxious fumes while operating the vehicle. I will return the vehicle for a third visit to resolve this concern.

12 Gasoline Fuel System problem

Failure Date: 04/07/2011

I agree with the other complaints about the fuel fumes. My husband had mentioned to me while I was warming my car that the smoke coming from the tail pipe was very strong. I then begin to notice fumes inside the vehicle and thought I was just imaging things. The highway safety commission need to look into to these complaints before someone get killed. I get sick and tired of going to the dealers and they claim nothing is wrong with the car. Hyundai need to wake up and look into these complaints.
