On the day of the Mid-Autumn Festival, the reverse camera and 360 stopped working. I went to the 4S shop the next day for recalibration to fix it. Because the steering wheel was vibrating while driving on the highway, I did a wheel balancing and four-wheel alignment. Today, while driving on the highway, I noticed that the speed range at which the steering wheel vibrates has expanded, and now the seat also vibrates above 124 km/h. Can any expert provide some guidance?
