Why 2017 and 2022 Nissan maxima have the same noise problem on the back side ?

Hello, first - if you have concerns with a vehicle you purchased, you should reach out to the selling dealership for possible assistance and guidance. Note that RepairPal does not sell cars. If you bought your vehicle rom CARMAX, see them directly. This is a forum to assist with vehicle technical and maintenance concerns - we cannot help with after sales issues. As far as a noise goes - a hands on inspection is needed to hear what is happening and trace it down to the root cause.
