The engine cover shakes when the Excelle is fast.

This should be caused by the aging of the rubber pad of the hood or improper adjustment of the rubber pad. After you open the hood, there are two spiral rubber particles on the top of the front bumper. Spinning the colloidal particles out a little higher can solve the problem. I hope I can help you. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
