When I was driving 70 mph with two bars left on the gas gauge (dashboard said distance to empty: 80 miles) , the car suddenly lost power and engine was turned off. When I try to start the car, I noticed that it was out of gas. I put a gallon of tank and it worked. Hoping that it was just one time problem, I was driving it carefully filling gas when it had three bars left on the gauge. A week later, while driving 25 mph, the vehicle shut off without warning when there were 4 bars (130miles to empty on the dash). Took it to the dealership and they told me be replace the fuel pump for $1,000 which I declined at the moment. I had 63,000 miles on the car and found out that many Sonata 2011 are having the similar problem.
I filled up my car on Thursday after filling it up the first time I started the car the gauge read full, later on while drive the fuel gauge said 3/4 full even though I had driven a few miles. The next day after taking my kids to school I stopped to run an errand. I get back in my car to start it up and the gas light is on and the fuel gauge says empty. After driving a few miles the gas gauges went up to 1/4 then eventually 1/2 tank. The gauge had been showing 3/4 full a few times in the past few weeks after filling up but this is the first time it's shown as empty.
