What Causes the Abnormal Noise When Accelerating the Xingrui?

[DiJohnny]

The reasons for abnormal noise when accelerating the Xingrui are as follows: Abnormal noise from the fuel pump motor: When there is wear or impurities inside the fuel pump motor, it can produce abnormal noise as the driver accelerates. This issue requires replacing the fuel pump. Abnormal noise from the throttle: Modern throttles are electronic, and the motor controls the opening and closing of the throttle valve. When the motor gears are worn, insufficient engagement can cause abnormal noise. Excessive carbon deposits or sludge in the throttle can also lead to noise. The throttle can be cleaned, but if the motor is damaged, the throttle needs to be disassembled to replace the servo motor. Abnormal noise due to poor lubrication of the accelerator pedal bearing: You can apply grease to the bearing for lubrication.

I just started driving the Xingrui not long ago, and one day when I stepped on the accelerator, I suddenly heard a 'squeaking' sound. I thought the engine was broken and was so scared that I immediately stopped to check. It turned out to be a loose engine belt causing friction at high speeds; a friend said it could also be an air intake system leak or aging shock absorbers, as these parts are prone to making strange noises during acceleration. Paying more attention to the car's condition and regular maintenance can prevent such issues, like tightening the belt or replacing aging parts. Don’t make a fuss like I did—just handle it simply, and don’t let small problems affect your driving mood.

Having driven for many years, I've encountered similar situations quite often. The most common causes of throttle noise in the Xingrui are loose or aged drive belts, or noise from the turbocharger at high RPMs; it could also be mechanical friction from worn pedal connecting cables. I advise against attempting DIY disassembly - it's best to go directly to a professional repair shop for diagnostic equipment inspection. Regular maintenance of the fuel system and engine is recommended to prevent the noise from worsening and leading to higher repair costs.

As a car enthusiast, I find the throttle noise of the Xingrui quite interesting. It's most likely vibration noise caused by high-speed rotating components like the turbo or drive belt. If it's not these, then we need to check for leaks in the exhaust system or intake manifold. Regular cleaning and oil changes can reduce such issues, and maintaining smooth engine operation is crucial. Listening carefully to the source of the sound while driving can help quickly locate the fault point.

When driving with kids, the most dreaded thing is strange noises, which are definitely a warning sign. The noise when stepping on the accelerator in the Xingrui could be due to worn parts like the pedal bearing or loose chassis connections. Delaying repairs can lead to serious issues during sudden acceleration. I immediately scheduled a check-up, emphasizing safety first—no delays. I also took the opportunity to have the interior wiring and tires inspected to ensure peace of mind for family trips.
