NHTSA Complaint #11535693 — 2021 NISSAN ROGUE

Started noticing the difference with the vehicle around 7,000 miles while driving at different speeds traveling to and from work. it did get worse over time and at 17,000 miles it was at the dealer and they stated that no issues were found or present. Vehicle will have excessive sway / bounce and will dip to one side depending what imperfections you will drive over during the trip. I have no idea how they test the vehicles at the dealer as there is an issue with it when stated to the personnel but at the end it seems to be nothing wrong. Does it take an accident to happen with severe injuries nowadays to have them take something serious. As a service technician my self by bouncing the rear bumper downwards it seems very bouncy, indicating bad shocks. If dealer's technician cant seem to see this then i have no words beyond the quality of service people get once they purchase the vehicles.
