Took car to dealer for oil change, front brakes and check engine light... was told tech wouldn't touch evap canister or purge valve because fuel lines were too corroded in the vicinity of the needed repair that they may fracture... this car is only 12 years old... coincidently my mother-in-law had a 2004 Hyundai xg350L in which the fuel tank and fuel lines were corroded to the point that they were leaking and she had to replace the vehicle D/T the cost of repairs... I too am now faced with replacing my vehicle D/T high repair costs... I have driven many automobiles, of note a 1967 VW beetle (during the years 1997 thru 2002) in Chicago with the snow and salt and never had issues with corrosion of any lines and I did all the work on that car! it was clean... what materials is Hyundai using for it's fuel lines and fuel tanks that they are corroding/rusting out... my car, the 2003 Hyundai Sonata was 100% garage kept!

The contact owns a 2003 Hyundai Sonata. The contact stated that gasoline spilled out of the contact's vehicle while refueling. The vehicle was taken to the dealer for diagnostic testing. The dealer stated that the fuel pump assembly valve would have to be replaced. The manufacturer stated that the VIN was excluded from NHTSA campaign number: 04V178000 (fuel system, gasoline). The vehicle was not repaired. The failure mileage was 80,000.

In 2005, I purchased a 2003 Hyundai Sonata. After purchasing my car, I found out that it had a recall on the fuel valve that the company had to re-install. This recall information was not on my carfax report. Later, the manufacturer had a recall on interior door handles that peeled and cut hands. Their solution was to wrap my handles with electrical tape; after my objection, they installed the same recalled handles. I've had my interior handles replaced three times because the manufacturer didn't make the handles out of a different material and chooses to reinstall the same recalled handle. On November 22nd, I went to capitol Hyundai to have them replace the recalled fuel valve, and interior door handles on my 2003 Hyundai Sonata. A service rep informed me that once the company replaces any recalled items the first time, it is the customer's responsibility to pay for them if they fail again. Surely, this cannot be correct! recalls do not expire and as long as the owner has the vehicle, the manufacturer/dealership should be responsible if their materials are continuously failing to meet safety requirements. What are folks making payments or can't afford another vehicle now supposed to do" drive around in a dangerous vehicle" be it 1 time or 1 million times, I want capitol Hyundai to indefinitely honor their recalls--at their expense.

I was informed this vehicle has a one-way safety valve in the fuel filler neck that when working properly will prevent fuel from escaping should there be a roll over. This valve must be stuck in the partially open position since if causes a significant restriction when fueling the car. When fueling the car, fuel does not flow properly and only accepts half gallon at a time before the fuel handle shuts off. Then I must wait for the gas in the filler neck to drop before I can continue to fuel vehicle and then continually repeat this process. Though very time consuming to fill it up, this is a safety issue since the valve does not operate as designed. I was informed it would cost over $600 to replace this valve and I would think it should be a manufacturer's defect. The consumer has no control that would influence the valve's proper functionality.

I was having great difficulty getting fuel into the vehicle. I took it to the Hyundai dealership in annapolis, md. They replaced the valve-canister cl, canister assy., and valve-purge contr. When I picked up the vehicle, the issue had not been resolved. I took it back and I'm not sure what other parts they may have replaced because I never again received any paper work. When I picked it up again, I was able to put gas in it, but it was leaking fuel all over the road afterwards. They had punctured a hole in my gas tank while working on it. It took approximately a month & four trips to the dealership to get this all resolved. And then on Aug. 4, 2014 I filled my gas tank up & fuel started leaking in the driveway again. Whatever they patched the hole in the gas tank with instead of replacing it, had blown. I contacted the dealership on Aug. 5, 2014. When the new serv. Mngr. Finally agreed to look at the vehicle on Aug. 12, 2014, he told me that it was in fact their fault & that he would order a new gas tank & it would arrive in 3-5 business. He also told me that they needed to replace all of the parts that I had already paid for back in Feb. I told him they already replaced them & he simply said ok & scratched them off the estimate of which he will not provide me a copy of. I have contacted them numerous times, but they still have not replaced the gas tank. I emailed the serv. Mngr. & copied the CEO yesterday hoping this might incite a response. The assist. Serv. Mngr. Emailed me this morning & asked me if I could drop it off next wed. I told him I had 2 appt.'s that day & could only do so if they could provide me with a vehicle. I have not heard back. I believe the issue of not being able to get fuel into the vehicle should be a recall as well from all of the people that I have seen on the internet searching for resolutions to the same problem with their Hyundai's.

Like many other complainants, for the past month, I have experienced problems filling up my gas tank. After only 1 gallon or less, the pump automatically shuts off as if the tank is full. It has taken me approximately 10 minutes just to put 1/4 tank of gas in my vehicle. When this first happened, gas overflowed and spilled on my shoes, my car, and the ground. Thinking there was a problem with the gas pump, I went to a different gas station and had the same problem. In viewing forums throughout the internet, this appears to be a problem that's been ongoing for several years now for this car model. It is a safety hazard due to the potential for gas to overflow onto a person and the outside of the vehicle, which could lead to a fire under certain circumstances.
