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.

When diagnosing a gas smell in your 2009 Lexus RX350, it's essential to adopt a systematic approach that begins with the most accessible components. Start by checking for fuel leaks, as these can often be the primary source of the odor. Inspect the fuel lines, tank, and injectors for any visible signs of damage or leakage. Next, ensure that the fuel cap is securely fastened, as a loose cap can allow gas vapors to escape, creating a noticeable smell. If these initial checks do not resolve the issue, turn your attention to the fuel filter; a clogged or damaged filter can also contribute to gas odors, so consider inspecting and replacing it if necessary. Additionally, examine the Evaporative Emission Control System (EVAP) for any leaks or malfunctions, as this system is designed to prevent gas vapors from escaping into the atmosphere. It's also wise to inspect the exhaust system for leaks, as these can sometimes mimic the smell of gasoline. Lastly, if the problem persists, consider the condition of the catalytic converter, as a failing unit can emit odors similar to gas. By following this diagnostic approach, you can effectively narrow down the potential causes of the gas smell and take appropriate action to resolve the issue. If you're uncertain at any point, consulting a qualified mechanic is advisable for a thorough inspection.
If you're detecting a gas smell in your 2009 Lexus RX350, it's crucial to understand the common problems that could be at play. One of the primary culprits could be a fuel leak, which may stem from a damaged fuel line or a malfunctioning fuel injector, leading to fuel escaping into the engine compartment or under the vehicle. Additionally, issues with the evaporative emissions system can contribute to this odor, as this system is designed to manage fuel vapors from the tank. A faulty or improperly sealed fuel cap is another frequent issue; if it's loose or damaged, it can allow vapors to escape, creating a noticeable smell inside the cabin. Furthermore, an exhaust system leak, particularly near the engine, can also result in gas odors infiltrating the vehicle. Lastly, engine performance problems, such as running too rich, can produce excess fuel vapors, intensifying the gas smell. Addressing these issues promptly is essential for safety, and while some DIY diagnostics can be performed, consulting a professional mechanic is advisable for a thorough inspection and resolution.
Addressing a gas smell in your 2009 Lexus RX350 is not just a matter of convenience; it is a pressing safety concern that requires immediate attention. Ignoring this warning sign can lead to severe consequences, including the risk of fire or explosion due to gas leaks. Additionally, inhaling gas fumes poses serious health risks, with symptoms ranging from dizziness and headaches to more severe complications with prolonged exposure. Beyond safety and health implications, neglecting a gas smell can also result in increased fuel consumption and potential damage to your vehicle's engine and components over time. Therefore, it is crucial to prioritize a professional inspection to identify and rectify the source of the gas smell, ensuring both your safety and the longevity of your Lexus RX350.
