2015 Hyundai Sonata: gas smell in the cabin

Filed Oct 31, 2026 · Fuel system · FL

The vehicle is currently at Greenway Orlando Hyundai for a fuel-system-related repair. During the dealership’s inspection, the dealership identified a crack in the fuel pump housing and a fuel leak. The dealership also provided photographs documenting the crack and the leak, and the vehicle has a very strong fuel odor. My primary concern is safety. A cracked fuel pump housing with a fuel leak presents a potential fire hazard. I do not believe it is safe to drive or operate the vehicle in this condition. The vehicle is being serviced in connection with Hyundai TSB 23-FL-004H, “Fuel Pump Filter Warranty Extension (TXXS), Inspection and Replacement.” The Prior Approval/goodwill issue is particularly important in this case. Note 2 on page 2 of TSB 23-FL-004H states that when a part not covered by the TSB is found to require replacement while performing the TXXS procedure, and that part is out of warranty, the dealership should submit a Prior Approval request for goodwill consideration before performing the work. When Greenway Orlando Hyundai identified the cracked fuel pump housing and the fuel leak, I asked the dealership to pursue this solution with Hyundai. Initially, the dealership refused to submit the Prior Approval/goodwill request. Because of that refusal, I personally contacted Hyundai, opened a complaint/case, and informed the dealership about the situation. I also insisted that the dealership submit the Prior Approval request contemplated by Hyundai’s procedure. Only after my insistence did Greenway Orlando Hyundai submit the Prior Approval/goodwill request to Hyundai. That request was subsequently denied. Therefore, I want to make it clear that I am not simply disputing the cost of a part that I chose to replace. The damaged component was identified by the dealership itself while the vehicle was undergoing fuel-system-related service. I asked the dealership to pursue the solution provided for under Hyundai’s procedure, but I had to take action directl

i've had my 2015 hyundai sonata now for A year. i took it to the hyundai place to have recalls on the security fixed. and told them about the valve cover gasket leaking. they said they fixed it. however every since i took it to the dealership i have had nothing but problems. my car makes a rattling noise when i accelerate, i smell a strong gas smell occasionally at random times but always while driving. my driver brake light has never worked, my driver headlight keeps blowing, my airbag light is now coming on randomly, my car has a bag vibration while going down the road, when i let off the gas it stops and i have replaced tires and still it won't go away no matter what i have done to fix it , and there has been many times after i return home the smell of something burning as off something is on fire is coming from my car. i have even been in panick thinking something today home was on fire but the smell was coming from my car. and others have even stated they smelled it as well. i've already taken out two loans to fix the valve cover gasket and the fuel pump filter, i can not keep taking out loans to fix problems that appears to be problems from the manufacturer and same problems others have had due to malfunctioning issues. i have children that ride in my car, i would hate for someone to get hurt or worse bc of manufacturing problems. then hyundai would have a bigger problem on their hands.

Vehicle is putting out a very strong gasoline odor, especially when sitting idle. I looked up previous recalls on the vehicle and seen where there was a recall I believe in 2022 for similar issues.

Gas smell on the passenger side front seat

Filed Sep 11, 2023 · Fuel system · AR

Noticed a smell of gasoline in the passenger compartment and took it to my local mechanic. Upon his inspection he found that the gas smell was caused by a crack on the plastic connector for the fuel line on top of the fuel pump. He showed this to me and recommended replacing the fuel pump as the connector is built into the pump and there was no proven way to fix the leak. Said leak caused gasoline fumes to fill the passenger compartment and therefore a risk of igniting a fire in the passenger compartment.

I have taken my car to mechanic and they have told me that my car is leaking gasoline. They recommended that I go to the dealer. When I called the dealer they told me that I would have to pay for the diagnosis. This is obviously concerning as gasoline fumes are toxic. There has been no warning lamps turned on this whole time but can definitely smell it when I finish my ride.
