This week my vehicle experienced a fuel line crack where the low pressure fuel pump connects to the direct injection fuel pump. The smell of gas was evident within the cabin while both stationary and in motion, and I could see vapor rising from the proximal portion of the hood while sitting in the driver's seat. The gas leak could be visualized upon starting the car. Upon opening the hood, I noted the gas leak around the cracked plastic connection. The fuel line was the original genuine Hyundai part. The Hyundai dealership replaced it with a superior (non-plastic) fuel line. The lack of quality in the original fuel line is concerning because it placed my family directly at risk to experience a dangerous and possibly fatal fire. It appears that the Hyundai dealership was also aware of this problem with the original line which is why they replaced it with a different part. However, there is no current recall campaign for this unsafe scenario.

On March 10 I took my Sonata to get an oil change at superlube. I also took the car on the 11th to the Hyundai dealership to check for a knocking noise I had heard in the car. They ran tests and told me my engine was fine, and I need brakes, an alignment, and tires. So I spent $800 getting these things done on my car including the oil change. Well on the 18th of March in traveling my car stopped in the middle of the highway. I crank up it drive for a minute and cut right back off again. So I had the car towed to my house. They ran tests, could not find anything wrong with the car, thought it was my pulley, but it was all right. So the mechanic said let's try another oil change. Started draining the oil, it was black as tar as if I had not gotten an oil change. Treated the gas and the fuel injection system. Still a knock in acceleration. Went back to superlube to give them a piece of my mind only to find out that the manager had been having problems with gdi engines and the fuel injection system. Told me that they knew about it and-and not saying anything. I was only mad because I had taken my car to Hyundai twice since I had the car in a year for engine inspection and not one time did they tell me this.
