What Causes the Hyundai Elantra to Shake While Driving?
2 Answers
The reasons why the Hyundai Elantra shakes while driving are: 1. Severe engine carbon buildup; 2. Poor performance of the ignition system, suboptimal spark plug ignition; 3. Unstable oil pressure. Taking the 2020 Hyundai Elantra Sport model as an example, its body dimensions are: length 4610mm, width 1800mm, height 1450mm, with a wheelbase of 2700mm, a fuel tank capacity of 53 liters, and a trunk capacity of 458 liters. The 2020 Hyundai Elantra Sport is equipped with a 1.4L turbocharged engine, delivering a maximum horsepower of 130PS, a maximum power of 95.6kW, and a maximum torque of 211Nm, paired with a 7-speed dual-clutch transmission.
I've repaired many cars and seen this situation quite often. It's mainly due to ignition system issues, such as aging spark plugs or faulty ignition coils, which can cause unstable engine operation. Tire imbalance is another common cause, especially when the front wheels are misaligned, leading to steering wheel vibration. Suspension system components like damaged shock absorbers or worn bearings can also cause severe car shaking. If the engine mount rubber pads are cracked, it can make the entire vehicle vibrate. Carbon deposits accumulating in the engine cylinders can affect combustion efficiency and worsen the shaking. I recommend starting with a simple ignition system check—replace the spark plugs first. If that doesn't help, consult a professional technician to diagnose the electrical circuits or suspension system. Don't ignore it, as minor issues left unattended may damage the engine or compromise driving safety, such as sudden loss of control at high speeds. Regular fuel system cleaning and tire balancing can effectively prevent this. This advice is based on actual repair experience to help everyone avoid more trouble.
