When opening the door to the 2025 Malibu LT, this odd noise seems to come from the trunk area. I thought I heard that this might be the fuel pump priming the system, but I wanted to know if others experienced this and what this might be. The attached video shows the sound coming from the rear area when the door is opened. I noticed it also happens when the car is unlocked with the key fob. The odd noise doesn't happen all the time, but if the car is sitting for a while, and then the door is opened, the sound occurs.
