How To Open The Gas Tank On Hyundai Palisade

The Hyundai Palisade is one of Hyundai’s most popular SUVs. This modern vehicle is equipped with many modern features and technology. One improvement Hyundai has made over the years is in the area of security. With keyless entry, auto-locking, and plenty of other features, Hyundai works hard to make a vehicle that is as secure as it is well-built. They have improved drastically on gas tank security while keeping it simple to open and close.

To open the gas tank on a Hyundai Palisade, you just need to make sure the driver’s door is unlocked. When the door is unlocked, you simply push in on the gas tank cover, and it will open for you to access the fuel cap for refueling. When you are finished, close the cover while the driver’s door is still unlocked. Locking the driver’s door will then lock the cover to keep others from accessing it.

Why Is My Gas Tank Not Opening?

Your gas tank may not be opening for a number of reasons. If you are driving a Hyundai Palisade, there are a few things you can check. First, you can make sure your driver’s side door is unlocked. If it is locked, your gas cover will also remain locked and unable to open. This is for the security of you and your vehicle, so your gas tank can not be tampered with.

After making sure your driver’s side door is unlocked and the gas cover still will not open, try applying a little more pressure or making multiple attempts to click the cover open. If this does not work, try unlocking or locking your driver’s side door to see if this fixes the issue. If it still does to work, try manually locking and unlocking the driver’s side door.

Should the problem persist, take it to the nearest mechanic or Hyundai dealership so they can professionally diagnose and fix the issue. After all, you do not want to accidentally cause more damage to the cover trying to solve the issue on your own with force. Carefully try to fix the problem without damaging your vehicle and then take it to a professional if you are unable to fix it by following the steps we recommend above.

What Happens If You Leave Your Gas Tank (Cap) Open?

Leaving your gas cap or cover open can be extremely dangerous to your vehicle and you. If you see it open while driving, immediately pull over and locate the cap to cover it. Leaving the vehicle without a gas cap runs the risk of allowing foreign objects or substances to enter the gas tank. Anything other than gas in the gas tank can cause detrimental harm to your vehicle and quite possibly be dangerous.

If you have lost the gas cap and are unable to close the cover, avoid driving the vehicle if possible and find a way to cover the hole to the tank to keep anything from getting in.

What Kind Of Gas Does A Hyundai Palisade Take?

The Hyundai Palisade uses unleaded gasoline. You find this type of gas in almost all gas stations unless it a gas station specifically for vehicles that take diesel fuel. 

Since we mentioned diesel fuel, make sure never to put diesel in a Hyundai Palisade unless a newer model in the future specifies it requires diesel. Putting diesel in a vehicle only made for unleaded gasoline can and will damage the vehicle. More than likely, it will keep it from being drivable and end up costing a lot to repair.

How Much Gas Does A Hyundai Palisade Take?

The Hyundai Palisade holds 18.8 gallons of unleaded fuel. This is fairly standard for an SUV but less for a larger SUV. Luckily, the Palisade gets anywhere from 19 to 26 miles per gallon, which is good for the size of the vehicle.

Certain models may have bigger or smaller gas tanks, and there are pros and cons to both. The con to a bigger gas tank is a heavier vehicle which may result in worse fuel economy. But typically, the advantages lead to more miles on a single tank of gas. This means you may be able to drive farther on one tank if you find an older year model with a bigger tank. This may be a good trade-off for some people.


All in all, owning a Hyundai Palisade gives you peace of mind when your vehicle is locked, knowing the gas cover is also locked, and able to keep others from tampering with it. Another advantage is knowing how easy it is to access it when the vehicle is unlocked. All you have to do is push on the cover to pop it open and refuel. This type of ingenuity and integration into the rush of everyday life allows for security and efficiency to exist in harmony. This is a big reason why Hyundai makes amazing and popular vehicles.
