I have a push button ignition. Three times this past week, my car has failed to start. When I press the button, all of the lights come on, but the engine does not turn over and when trying to press the break in conjunction with pressing the push start engine button, the break pedal is stiff and does not press downward. The third time this occurred, I was stranded for 1.5 hours. My brother came to give me a "jump" as he thought it was my battery only for sparks to come from my battery and for his cables to get so hot that they melted. I had my car owed to allen samuel's Hyundai in North richland hills, tx the next morning only to be told that because they are unable to "recreate" the issue, there is nothing they can do. I also reached out to Hyundai and was told that since there are no recalls, there is nothing they can do. This is a safety issue and because they are unable to recreate or do not have any recalls, then I am stuck with a lemon car. The second issue I have been facing (which has been ongoing) is the sensor in my gas tank recognizes my tank as "full" when I fill up with gas but this is not indicated on the gas hand readout. Again, this was brought to Hyundai's attention and because they can't "see it", "recreate it" and there are no "recalls", then there is nothing that they can do. Again, this is another safety hazard as I may think I have a certain amount of gas in my car when in reality I do not. The first issue occurs when the car is stationary. The first time I was at home, the second time I was at work and the last time (most recent) I was at a restaurant. I believe the cause of both issues are sensors with the break that connects it to the push button and a sensor in the tank that connects it to the gas hand. The gas hand issues occurs each time I put gas in my car.

Had a near death incident at freeway speeds in heavy rain when the car lost total control, hydro-planed from the 2nd to left lane and hit the cement barricade on the left and in the process the steering wheel is locked along with the brakes and with that impact, ricocheted all the way to the right hand shoulder of a 4-lane freeway before coming to a stop. Freeway is 280 S (san francisco to san jose). Location was palo alto, just a few miles after sand hill rd exit (menlo park) where the freeway is just straight for miles without any steep curves. Have driven so many other brands over the last 20 years in heavy rain on the same freeway without an incident. The car cannot handle freeway speeds and became very unstable. Could be defective tires, their technology controlling the wet traction which caused hydroplaning etc fortunately there were no other cars in proximity else could have been a bigger accident.

I was traveling East on us I90 in charlton MA in heavy holiday traffic keeping a safe interval as cars kept braking off and on and someone a dozen cars up slammed on thier brakes causing a chain reaction. I hit my brakes hard also but did not slow down fast as if I was still pressing on gas pedal I was slowing but not (right ?) or fast enough as I was standing on brake but still keep moving faster ahead then seemed right? this had happened a month or so before and I thought maybe my rug had slipped under brake petal and over my gas pedal as it seemed the harder I pressed on brake I still kept moving forward as if both were being pressed at the same time it seemed very odd or erie as I just kept moving forward. I did manage to stop just in time before I hit his bumper. Like I said I thought at the time maybe the rug had slipped or something because it had slipped off the hook on the floor but it had not realy moved that much and I secured it with hook on floor and checked to make sure it was still secure the second time in July 3rd and it was. Since then I have read about 2014 Sonatas having problems with thier brakes that fits what happened exactly on over 800,000

100 % brake failure. 45 mph, moderate traffic, 6:30pm Thursday May 7th 2015, dry pavement and approaching traffic that which made an abrupt stop ahead. Stepped on brake pedal, pedal fluttered as if anti locking brake activity was be activated. Car continued to free wheel forward, I stepped harder on brake pedal and pedal began pushing back to me. The harder I pushed the brake pedal the more it pushed back (there was no braking action).the vehicle failed to stop, and had enough distance to stop (I had a minimum following distance of two car spaces) but brakes failed to do so which caused me to crash into the vehicle in front of me. I have owned many cars such as Dodge charger 2006 SXT/Chevy Malibu 2009 to name a few and never had this problem when applying the brakes. I'm the first owner of this car and this is the first Hyundai I have ever bought.
