Is it normal for the accelerator pedal to have slight vibration?

It is normal for the accelerator pedal to have slight vibration. In some automatic transmission cars, when the gear is in D and the brake is pressed, both the accelerator pedal and the brake pedal may experience some vibration. If the vibration becomes more noticeable or severe, it may be caused by damage to the engine mount, which needs to be replaced as soon as possible. The car's engine is not directly connected to the frame; there are rubber engine mounts at the connection points between the engine and the frame. The purpose of these mounts is to absorb vibrations, preventing the engine's vibrations from being directly transmitted to the car body. Rubber products can age over time, and when the rubber engine mounts age, they may harden, causing the engine's vibrations to be directly transmitted to the car body.
I've been driving for over a decade, and slight vibration in the accelerator pedal is actually quite common. During normal driving, especially when going over uneven roads, engine vibrations traveling through the body to the pedal are normal—just like the natural vibration of a mobile phone. However, if a high-frequency tingling sensation suddenly appears when the RPM is stable, then it's something to pay attention to. Last week, my neighbor's old SUV went into the shop for this very issue, and it turned out to be amplified vibrations due to aging engine mounts. I recommend observing the vibration patterns more closely and maintaining regular checks on tire balance and engine mounts. After all, vibrations are both the vehicle's way of communicating and an alarm for potential problems.
