Here are the reasons for engine vibration in a new car: 1. Improper air-fuel mixture ratio in the engine compartment. 2. Poor fuel quality. 3. Faulty electronic control system. Below are precautions for driving a new car: 1. Maintain smooth and stable starts. 2. Start in low gear. 3. Shift gears promptly while driving. 4. Choose good road surfaces. 5. Use high-quality fuel and engine oil.
I just got a new car and it's already experiencing engine vibration, which seems quite common. The causes of vibration are usually minor faults in the ignition system, such as improperly installed spark plugs or excessive gaps, leading to unstable engine operation. The fuel system could also be problematic—low fuel pump pressure or clogged injectors can result in incomplete combustion of the air-fuel mixture. Additionally, loose engine mounts can transmit vibrations directly to the body, a common issue during the break-in period of new cars. Carbon buildup is another factor; though rare in new cars, poor fuel quality or improper refueling can quickly accumulate and affect cylinder efficiency. If you notice vibration, don't delay—visit the dealership promptly for a diagnostic scan to ensure safety. The inspection process is straightforward: first, observe during a cold start, then check the spark plugs and fuel filter.
