It is normal for the accelerator pedal to have a slight vibration. Here is some relevant information about the accelerator pedal: 1. In some automatic transmission cars, when in D gear and pressing the brake, both the accelerator pedal and brake pedal may feel vibrations. 2. Slight vibration is normal, but if there is noticeable or severe vibration, it may be caused by damage to the engine mounts. Additional information: 1. The car engine is not directly connected to the frame. 2. There are rubber engine mounts at the connection points between the engine and the frame. 3. The purpose of the engine mounts is to absorb vibrations and prevent the engine's vibrations from being directly transmitted to the car body. 4. Rubber products will age over time, and when the rubber mounts age, they may harden.

Having driven for over a decade, I've encountered quite a few instances of slight throttle pedal vibration, which is quite common in certain car models. For example, there can be some feedback in power output when the engine is at low RPM, especially during idling or low-speed acceleration. If the vibration is uniform and slight, it's usually not a big issue—after all, some vibration is inevitable with mechanical components in motion. However, if the vibration suddenly intensifies, becomes irregular, or is accompanied by steering wheel shaking, then you should be cautious. Possible causes include unbalanced tires, warped brake rotors, or loose engine mounts. I recommend regularly checking tire balance and wheel alignment—don’t wait until the issue becomes severe before addressing it. A friend of mine ended up spending unnecessary money on part replacements due to neglect. Paying attention to changes in vibration while driving can help prevent major repairs down the line.

I have some experience in mechanical maintenance. It's by design that many cars have slight vibrations in the accelerator pedal, caused by minor resonance from the engine or drivetrain during operation. Normal vibrations typically occur at specific speeds, such as brief, mild shaking at 40-60 km/h. Abnormal cases like persistent vibrations or severe jerking can pose safety hazards, such as wheel imbalance, suspension system issues, or engine malfunctions. I recommend first checking for even tire wear and proper tire pressure. If that doesn't help, use professional equipment to test wheel balance. When driving, avoid sudden acceleration to test vibration patterns—prioritizing safety can save both trouble and money.

I just got my driver's license, and I've noticed slight vibrations in the accelerator pedal when driving my own car. At first, I was quite nervous, thinking it might be broken. Later, I learned that this is common in many cars—it's a normal minor feedback from the engine's power transmission, especially noticeable during slow city driving. If it doesn’t affect driving and there’s no noise, you can observe it for a few days. However, if the vibration suddenly appears or becomes strong enough to make your foot numb, go to a repair shop immediately—it could be a tire balancing issue or brake problem. Last time, I fixed this minor issue in time and avoided bigger trouble. Beginners shouldn’t guess blindly.
