What causes the vibration in the Arrizo GX accelerator pedal?
2 Answers
The reasons for the vibration in the Arrizo GX accelerator pedal are: 1. The engine mount rubber of the car has aged or worn out; 2. Resonance caused by vibrations from other components of the car at certain speeds being transmitted to the accelerator pedal. The Arrizo GX is a compact car under the Chery brand. Taking the Arrizo GX 2019 Pro Manual Jinshe Edition National VI as an example, its body dimensions are: length 4710 mm, width 1825 mm, height 1490 mm, with a wheelbase of 2670 mm. The Arrizo GX 2019 Pro Manual Jinshe Edition National VI is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 156 hp, a maximum power of 115 kW, and a maximum power speed of 5500 rpm.
My Arrizo GX's accelerator pedal has been vibrating lately, feeling like a tiny motor is bouncing under my foot—really uncomfortable. I suspect it might be an engine issue, like aging spark plugs causing excessive engine vibration that transmits through the pedal. Alternatively, there could be a driveline imbalance issue, making the vibration more noticeable during turns, or maybe the pedal's sensor wiring is loose, disrupting the signal. During my last maintenance visit, the mechanic reminded me to regularly check tire pressure since unbalanced tires can also cause whole-car vibrations that affect the pedal. I suggest first inspecting the engine bay—replace dirty spark plugs promptly, or the shaking will worsen. If you're not confident handling it yourself, take it to a proper repair shop to check the entire drivetrain system to avoid compromising driving safety.
