Is It Normal to Feel Slight Vibration in the Accelerator Pedal?

It is normal to feel slight vibration in the accelerator pedal. In some automatic transmission cars, when in D gear and stepping on the brake, both the accelerator and brake pedals may exhibit some vibration sensation. Minor vibrations are normal. However, if the vibration becomes noticeably strong or severe, it might be caused by a damaged engine mount. 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. These mounts serve to absorb vibrations, preventing the engine's vibrations from being directly transmitted to the vehicle body. Rubber components can age over time, and when the rubber engine mounts age, they tend to harden.

It's quite common to feel a slight vibration in the footrest when stepping on the gas pedal. I experienced it too when my car had just passed 20,000 kilometers, especially noticeable when accelerating on the highway. During maintenance, the mechanic mentioned the tire dynamic balance was slightly off, and after reattaching the balancing weights, the issue was immediately resolved. If the vibration occurs only at specific speed ranges, say 80-100 km/h, it's most likely a wheel balance issue. Worn engine mounts or drive shafts can also transmit vibrations to the accelerator. Don't ignore it—if the steering wheel starts shaking too, get it checked right away.

I've been driving a taxi for over twenty years, and whether the throttle vibrates depends on the situation. A slight vibration during the break-in period of a new car or after changing new tires is normal and may disappear on its own after a while. However, if the vibration is noticeable during cold starts or the steering wheel shakes during high-speed braking, it's likely due to warped brake rotors—get it fixed immediately! I remember one time when my car vibrated so badly during acceleration on a slope that my foot went numb—it turned out the universal joint on the driveshaft was completely worn out, almost leaving me stranded on the road.

Last week, while driving my child to school, I noticed a numbness in the sole of my foot when pressing the accelerator, which scared me into heading straight to the repair shop. The mechanic connected a diagnostic tool to the car's computer and checked for half an hour, finally discovering it was caused by a bulge on the inner side of the right front tire! After replacing the tire, the vibration disappeared immediately. They said a dirty throttle could also cause the engine to shudder, transmitting vibrations to the pedal like a phone vibrating. Now, when I encounter speed bumps, I go over them slowly, as scraping the tire sidewall against the curb is the easiest way to plant a hidden danger.
