On Monday, 3/9/15, I drove my 2011 Genesis with 61,000 miles over 200 miles. I refueled that evening when it had about a 1/4 of a tank. Went to the same station I have used for 18 years. Tuesday I drove about 20 miles before meeting my wife for lunch, the car ran super. Came out and the car would not start, engine turned over but would not catch. Had the car towed to the dealer and was told the gas pump was bad and a new one had to be ordered (over $400, thank God for my extended warranty). They replaced the pump and it still would not start so they told me there was water in the tank. This tank was a full tank with only 20 miles driven. They said they have a sample and I need to contact the gas station. They said if they reported this to the extended warranty company they would not cover the fuel pump. I was told that they had to drop the fuel tank and my portion of the bill was up over $500 so far and it still doesn't start. I did contact the gas station and they said there were no other complaints, my wife had filled our pick up the same morning at the same station and no problems. I contacted the Dept. of Agriculture (FL) and they sent a tech out who verified there was no problem at the gas station and no other complaints were received. As I had to take another long trip, the dealer got me a rental car on Thursday to return Friday. Friday the dealership called and said they replaced the spark plugs and needed to get a new fuel sending unit and to keep the rental until it is done on Monday 3/16/15. Obviously there was no problem with the gas. This car ran beautifully until it wouldn't start. Three weeks before, a check engine light came on and the dealer reset it but never said why it came on. It appears the dealer does not know what is wrong and is now replacing everything!! We love our Genesis and our family has bought 5 Hyundais from this dealership over the past 11 years. Any suggestions???
