Apparently, there is no fuel door release button in the Chevy Malibu. But there's no big fuss about this because you can simply push on the fuel door until it pops open. 

For some, it may be bizarre for Malibu to miss this important part because a fuel door release button could come in handy, specifically on keeping your gas tank secure. A fuel door release button somehow helps to lessen the possibility of thieves siphoning on your gas. 

Also, it gives you the reassurance that your fuel door is closed or opened correctly because it's kind of hard to see it from the driver's seat. 

Luckily, the capless gas tank system equipped on the Chevy Malibu has an anti-siphoning feature that has various mechanisms in the neck filler that makes it hard to stuff in a garden hose and drain the tank. 

For the standard cap system, an alternative to keep your gas safe is to purchase a locking gas cap to guarantee you the safekeeping you need for your fuel. 

Rovike's locking gas cap is compatible with the Chevy Malibu. Although made of plastic, it is a great tool to replace it with Malibu's standard cap that has no lock. It is durable and complements a lot of other types of vehicle models.

What Does It Mean When Gas Tank Isn't Opening?

If you're having trouble with opening your Malibu gas tank despite doing the following instructions accurately, then it may be possible that there are problems within the car. 

Gas is one of the most essential materials to make your car run, and so when a gas tank door isn't opening, this calls for great concern because it can greatly affect the functionality of your vehicle. 

Here are a few reasons as to why your gas tank door isn't opening: 

Damaged Fuel Door Hinge

This can be caused by loose or rigid pins and bushings. Like all doors in your vehicle, it relies on a hinge to help it open and close which is why it's hard to open the gas tank door once its hinge goes bad. 

Exterior Damage Near Fuel Door 

In cases where your car's exterior has encountered a great impact, it is possible that it will also damage the fuel door. A small gash where the hinge is located can squash this part and keep it stiff when opening. The best way to handle this is to immediately repair the damaged part and have the fuel door checked. 

Broken Fuel Door Release 

Some vehicles have fuel door release buttons to open the gas tank door. This is usually a button on the car keys or a lever to be pulled near the driver's seat. When this is broken, of course, it automatically makes the gas tank door impossible to open as it will need the signal of the door release button. 

If one of these problems persists, it is highly recommended to consult a mechanic as they have the skills and knowledge to thoroughly examine the fuel tank door and find the accurate diagnosis of causing the inconvenience.
