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 you detect a gas smell in your 2017 Cadillac ATS, it's essential to approach the diagnosis methodically to identify the root cause effectively. Start by inspecting the vehicle for any visible fuel leaks, as these can often be the most straightforward issues to resolve. Look under the car for any signs of fuel pooling or wet spots, which may indicate a leaking fuel line or injector. Next, check the fuel cap; a loose or damaged cap can allow gas vapors to escape, creating an odor inside the vehicle. If these initial checks do not reveal the problem, consider using a diagnostic scanner to check for error codes that may point to issues within the fuel system or the evaporative emissions system. Pay particular attention to components like the charcoal canister and purge valve, as these can also contribute to gas smells if they are damaged or leaking. Additionally, inspect the exhaust system for any cracks or leaks, as these can sometimes mimic a gas odor. Finally, monitor the engine's performance; if it is running too rich or if there are issues with the catalytic converter, these could also be sources of the smell. By following this structured approach, you can effectively diagnose and address the gas smell in your Cadillac ATS, ensuring a safer and more pleasant driving experience.
When you detect a gas smell in your 2017 Cadillac ATS, it’s crucial to identify the underlying cause to ensure both safety and vehicle performance. One of the most common culprits is a fuel leak, which can stem from damaged fuel lines, a faulty fuel injector, or even a cracked fuel tank. Additionally, issues with the evaporative emissions system, such as a malfunctioning charcoal canister or purge valve, can lead to gas odors inside the cabin. Another frequent issue is a faulty fuel cap; if it’s loose, damaged, or not sealed properly, it can allow fuel vapors to escape. Furthermore, problems within the exhaust system, including leaks or a damaged catalytic converter, may also contribute to the gas smell entering the vehicle. Lastly, engine-related issues, such as a rich fuel mixture or malfunctioning sensors, can exacerbate the problem. If you notice a persistent gas odor, it’s advisable to conduct a thorough inspection or consult a qualified mechanic to diagnose and resolve the issue effectively, ensuring your vehicle remains safe and reliable.
Addressing a gas smell in your 2017 Cadillac ATS is not just a matter of convenience; it is a pressing safety concern that requires immediate attention. Gas leaks pose a significant risk of fire or explosion, particularly in a vehicle where flammable materials are present.

Furthermore, neglecting this issue can result in more extensive damage to your vehicle's components, leading to costly repairs down the line. Therefore, if you detect a gas smell, it is imperative to seek professional assistance from a qualified mechanic or dealership without delay.
