What should I do if there is abnormal noise in Ming Rui's rapid acceleration?

There are two kinds of automatic gears in this model, one is a six-speed automatic manual at gearbox, and the other is a six-speed dual-clutch gearbox. I don't know which one you have.

If it is a double clutch, it is normal to have abnormal noise, because Buick's double clutch is not done well, and they can't solve this abnormal noise. This slight abnormal noise does not affect driving.

If it is an automatic at gearbox, it is wrong to have abnormal noise, which needs to be carefully checked.
