What to do if the fuel tank cap of Mercedes-Benz GLE won't open?

This situation is relatively common. You can insert a small wooden piece into the gap of the fuel tank cap to pry it open. Remember to pull the fuel tank cap's latch switch while prying. You can open the trunk. On the side of the fuel tank cap, there is usually an interior panel that can be opened, typically secured with just a few plastic clips, making it easy to access. You can install a small spring (not too soft or too long) on the protruding rubber pad of the fuel tank to increase the elasticity between the fuel tank cap and the locking mechanism. Apply lubricating grease to the hinges and the engagement points of the fuel tank cap.
Last time at the gas station, I encountered a situation where the fuel tank cap of my Mercedes-Benz GLE wouldn't open, which was really frustrating. The first thing to check is whether the car doors are locked, as some vehicles have the fuel tank cap linked to the door locks—try unlocking the doors. If that doesn't work, it might be an issue with the electronic system, such as a stuck button or dust blockage. Gently tap around the cap opening with a small tool, but avoid using too much force to prevent scratching the paint. In winter, low temperatures make it more prone to freezing; pouring some warm water can help open it. If it still doesn't work, I suggest not forcing it and contacting a Mercedes-Benz 4S店 immediately. They can use professional equipment to diagnose whether it's a circuit or battery issue. Trying to fix it yourself might damage parts, wasting both time and money. When parking, make sure not to let debris accumulate around the fuel filler opening—keeping it clean can reduce the chance of malfunctions.
