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.

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 faced with a gas smell in your 2017 INFINITI Q50, it's crucial to adopt a methodical diagnostic approach to identify the source of the issue. Start by visually inspecting the area around your vehicle for any obvious signs of fuel leaks, such as puddles or wet spots beneath the car. Next, examine the fuel lines and connections for any damage, corrosion, or loose fittings that could be contributing to the odor. Don’t overlook the fuel cap; ensure it is securely tightened, as a loose cap can allow gas vapors to escape. Additionally, inspect the fuel injector for any leaks, as well as the exhaust system, since leaks here can sometimes mimic a gas smell inside the cabin. It’s also wise to check the evaporative emissions control system for any malfunctions, as issues in this area can lead to similar symptoms. If these initial checks do not reveal the problem, consider inspecting the fuel tank itself for leaks or other concerns. By following this structured approach, you can effectively narrow down the potential causes of the gas smell and take the necessary steps to resolve the issue.
If your 2017 INFINITI Q50 is emitting a gas smell, it’s crucial to identify the underlying cause to ensure your safety and the vehicle's performance. One of the most common culprits is a fuel leak, which can occur from damaged fuel lines, injectors, or even the fuel tank itself. Inspecting these components for any visible signs of wear or damage can be a good starting point. Additionally, a faulty fuel injector may leak fuel into the engine compartment, contributing to the odor. Another area to check is the evaporative emissions system; issues with parts like the charcoal canister or purge valve can lead to gas vapors escaping into the cabin. Don’t overlook the gas cap, as a loose or damaged cap can allow vapors to escape, creating a noticeable smell. Lastly, consider the exhaust system; a leak near the engine can sometimes mimic a gas smell inside the vehicle. While some of these checks can be performed at home, it’s advisable to consult a qualified mechanic for a thorough inspection to address any serious issues effectively.
Addressing a gas smell in your 2017 INFINITI Q50 is not just a matter of inconvenience; it is a pressing safety concern that requires immediate attention. Gas leaks pose a significant risk of fire or explosion, making it essential to act quickly. Additionally, inhaling gas fumes can lead to serious health issues, including dizziness, headaches, and nausea, which can escalate with prolonged exposure. Beyond the immediate health and safety risks, neglecting a gas smell can result in further damage to your vehicle, leading to costly repairs down the line. Therefore, if you detect a gas odor, it is crucial to stop driving, ventilate the area, and seek a professional inspection without delay. Prioritizing these steps will help ensure your safety and the longevity of your vehicle.
