The most common reasons a 2017 Chevrolet Cruze smells like gas are the gas cap, the fuel system, or the emissions control system.
  • Gas Cap: A loose or damaged gas cap can cause fuel vapors to escape, triggering the check engine light and potentially affecting fuel system pressure.
  • Emissions Control System: A faulty emissions control system can lead to increased hydrocarbon emissions and trigger the check engine light due to malfunctioning components like the EGR valve or O2 sensors.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

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.

What are the potential causes and diagnostic steps for a gas smell in a 2017 Chevrolet Cruze?

When faced with a gas smell in your 2017 Chevrolet Cruze, it's essential to adopt a systematic diagnostic approach to identify the root cause. Start by visually inspecting the fuel system for any obvious leaks, focusing on components like fuel lines, injectors, and the fuel tank. Next, examine the evaporative emissions system, particularly the charcoal canister and purge valve, as these can often be culprits in gas odor issues. Don't overlook the exhaust system; check for cracks or damage that could lead to gas smells escaping. Additionally, ensure that the fuel cap is secure and in good condition, as a loose or damaged cap can allow vapors to escape. If these initial checks do not reveal the problem, consider using a diagnostic scanner to look for engine codes that might indicate fuel mixture or emissions issues. Finally, monitor your vehicle's performance for any changes, such as decreased fuel efficiency or unusual engine behavior, which could signal deeper problems. By following this structured approach, you can effectively diagnose and address the gas smell in your Cruze, ensuring both safety and vehicle reliability.

What are the common causes of a gas smell in a 2017 Chevrolet Cruze?

When you detect a gas smell in your 2017 Chevrolet Cruze, it's crucial to identify the underlying issues 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 or faulty fuel injectors, leading to a noticeable odor both inside and outside the car. Additionally, problems with the evaporative emissions system can cause fuel vapors to escape, contributing to the smell. A simple yet often overlooked issue could be a faulty fuel cap; if it's loose or damaged, it can allow vapors to escape. Furthermore, an exhaust system leak, particularly near the catalytic converter or muffler, can produce a gas-like odor that infiltrates the cabin. Lastly, engine-related issues, such as malfunctioning sensors or problems with the fuel injection system, can also lead to a gas smell. If you encounter this issue, it's advisable to conduct a thorough inspection of these components or consult a qualified mechanic to diagnose and resolve the problem effectively. Addressing these concerns promptly not only enhances your vehicle's safety but also prevents potential hazards associated with fuel leaks.

How urgent is it to address a gas smell in a 2017 Chevrolet Cruze?

Addressing a gas smell in your 2017 Chevrolet Cruze is of utmost urgency due to the serious safety risks involved. Gasoline is not only highly flammable, but a persistent gas odor may indicate a fuel leak, which can lead to a fire hazard if left unchecked. Additionally, inhaling gasoline fumes poses health risks, including headaches, dizziness, and nausea, which can affect your well-being and that of your passengers. Ignoring this warning sign can also result in more severe damage to your vehicle's fuel system, leading to expensive repairs down the line. Therefore, if you detect a gas smell, it is crucial to act immediately by consulting a qualified mechanic to diagnose and resolve the issue, ensuring both your safety and the longevity of your vehicle.
