The check engine light will illuminate any time there is a failed EVAP system test. This will be indicated by the various on-board diagnostics trouble codes that are stored in the vehicle's memory. Also, in some models, there may be a popping sound accompanying the check engine light, as the leak detection pump continuously attempts to pressurize the fuel tank. The canister may also cause difficulty starting the engine, a rough idle, and poor fuel mileage.
When the fuel filter begins to clog, the engine suffers from fuel starvation. This will cause a significant reduction in power and may also cause a misfire. These conditions may be intermittent, or constant and worsen over time. As the issue progresses, the engine may being to stall immediately after starting, fail to start, hesitate under throttle, or stall at particular angles on hills.

Also, in some models, there may be a popping sound accompanying the check engine light, as the leak detection pump continuously attempts to pressurize the fuel tank. A fuel tank leak may also cause difficulty starting the engine, a rough idle, and poor fuel mileage. When a fuel tank is simply corroded to the point of failure, the exterior tank condition rarely shows damage. The inside of the fuel tank will be rusted or corroded, and rust flakes or other debris may be floating in the fuel.
For most vehicles, the only symptom will be a check engine light or fuel tank filler cap light illuminating on the driver instrument cluster. This is to signal that there is an evaporative emissions (EVAP) leak. In some situations, the vehicle may take longer than normal to start, or, more rarely, the engine may not start at all. on-board diagnostic (OBD) trouble codes will refer to EVAP system failures such as a small or massive EVAP system leak. Lastly, the powertrain control module may notice a lean running condition, which could even lead to random and infrequent misfires.
When dealing with a gas smell in your 2013 Hyundai Genesis Coupe, it's essential to adopt a systematic diagnostic approach. Start by inspecting the Evaporative Emission Control (EVAP) system, as issues with the EVAP canister or associated components are common culprits. Look for any visible leaks or damage in the hoses and valves. Next, examine the Positive Crankcase Ventilation (PCV) hose, as a blockage or fault here can also contribute to fuel odors; replacing it may be necessary if you find any issues. Don’t overlook the Fuel Pump access cover, located under the rear seat, where a loose or damaged gasket can lead to gas smells. Additionally, inspect the fuel tank seal for any signs of wear or looseness that could allow vapors to escape. Finally, conduct a thorough check for any other potential leaks under the hood and beneath the vehicle. If these steps do not resolve the issue, consulting with a Hyundai dealer can provide further insights, especially if there are known issues specific to your model. By following this methodical approach, you can effectively identify and address the source of the gas smell in your vehicle.
If you're detecting a gas smell in your 2013 Hyundai Genesis Coupe, it's essential to investigate several key areas that could be contributing to the issue. Start by examining the fuel system, particularly the fuel pump access cover located under the rear seat on the driver's side; a loose or leaking gasket here can lead to fuel vapors escaping. Additionally, ensure that the gas cap is securely tightened and in good condition, as a faulty cap can also allow vapors to seep into the cabin. Next, consider the emissions control system, specifically the EVAP system, which includes components like the canister close valve and vapor vent hose; any malfunction in these parts can result in noticeable gas odors. Don't overlook the Positive Crankcase Ventilation (PCV) system, as a compromised PCV hose may also be a culprit, and Hyundai has acknowledged this issue in service bulletins. Lastly, if your vehicle is relatively new, remember that the exhaust system might emit initial odors that could be mistaken for gas smells, particularly from the catalytic converters. By systematically checking these areas, you can identify the source of the gas smell and take appropriate action, whether that involves tightening a cap, replacing a hose, or seeking professional assistance for more complex repairs.
If your 2013 Hyundai Genesis Coupe has a gasoline smell, it’s crucial to address the issue promptly to avoid serious safety risks and potential damage to your vehicle. A gasoline odor can indicate a fuel leak, which not only poses a fire hazard but can also lead to costly repairs if left unchecked. Start by checking the gas cap to ensure it’s securely tightened, as a loose cap can allow fumes to escape. Next, inspect the fuel tank and vacuum line for blockages, as fuel can seep into areas where it shouldn’t be, leading to unpleasant odors in the cabin. Additionally, examine the fuel pump access cover for any leaks or loose gaskets, as these can also contribute to the problem. If the EVAP system is malfunctioning, it may require professional testing to prevent further complications. Remember, driving habits can exacerbate the issue, so avoid overfilling the tank and be cautious with sharp maneuvers. If the smell persists despite your efforts, it’s essential to consult a Hyundai dealer for a thorough inspection. Ignoring these symptoms can lead to more severe consequences, making it imperative to act swiftly.
