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.
To effectively diagnose the gas smell in your 2016 Buick Verano, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the area under your vehicle for any visible gasoline leaks, as this can provide immediate insight into the problem. Next, ensure that the fuel cap is securely tightened, as a loose or damaged cap is a common culprit for gas odors. If these initial checks do not reveal the source, proceed to examine the fuel lines for any signs of cracks or damage, as compromised lines can lead to fuel leaks. Additionally, consider the condition of the fuel injector, as a malfunctioning injector may also contribute to the smell. Don’t overlook the fuel tank itself; any leaks or damage here can be significant. Finally, if the smell persists, investigate potential issues with the exhaust system, as leaks or failures in this area can mimic fuel odors. By following this diagnostic approach, you can efficiently identify and address the source of the gas smell in your vehicle.
If your 2016 Buick Verano has developed a gas smell, it’s crucial to investigate the underlying issues promptly, as they can pose serious safety risks. One of the most common culprits is a fuel leak, which can occur due to a cracked fuel line or a faulty fuel injector, allowing gasoline to escape into areas where it shouldn't be. Additionally, a loose or damaged gas cap can lead to fuel vapors escaping, creating a noticeable odor inside the vehicle. It's also important to consider the possibility of a malfunctioning high-pressure fuel pump, which may leak fuel into the crankcase, resulting in a rich fuel mixture that can cause the exhaust to smell like gas. Other factors, such as a failing air-fuel mixture or issues with the vehicle's exhaust system, can contribute to this problem as well. Given the volatile nature of gasoline, addressing any gas smell immediately is essential to prevent potential fire hazards and ensure the safe operation of your vehicle. Regular maintenance checks and being vigilant about any unusual smells can help you catch these issues early, keeping your Buick Verano running smoothly and safely.
Addressing a gas smell in your 2016 Buick Verano is not just a matter of comfort; it is a critical safety concern that demands immediate attention. Ignoring the odor can lead to severe consequences, including the risk of fire or explosion due to gasoline leaks. Additionally, the health implications of inhaling gasoline fumes are significant, as they can cause dizziness, headaches, and nausea, with prolonged exposure potentially leading to more serious health issues. A gas smell often indicates a leak in the fuel system, which, if left unaddressed, can result in further damage to your vehicle and costly repairs. Therefore, it is essential to prioritize this issue and seek professional assistance to diagnose and resolve the source of the odor promptly, ensuring both your safety and the proper functioning of your car.
