Why does the Elantra make abnormal noise and shake when braking in D gear?
1 Answers
Abnormal noise and shaking when braking in D gear on the Elantra may be caused by excessive carbon deposits in the engine or a mismatch between the engine oil quality and the engine. Specific reasons: Excessive carbon deposits in the engine. This situation mainly occurs when gasoline is not fully absorbed into the engine, leading to the formation of carbon deposits, which causes the car to shake and increases fuel consumption. Once the engine oil viscosity is too high, it can lead to increased fuel consumption and carbon deposit formation. Solutions: Check the car's spark plugs. If a certain cylinder's spark plug cannot ignite normally, it will cause the engine to run unevenly. At this time, the vibration at idle speed will be very noticeable, and it will also be accompanied by a decrease in power. You can go to a 4S shop to find relevant professionals for maintenance.
