I recently purchased my Mercedes from Auto Boutique in Pearland, Texas (713) 352-0777. 1.The vehicle's air suspension system is constantly grinding, and moving/adjusting while being driven. It feels like the vehicles fame is off balance. 2. The back camera system does not work unless the radio is turned on; which is very alarming not to mention dangerous. 3. All the tires are registering improper inflation errors even though no air has been added or removed. I took the vehicle back to the place of origin; but they are not Mercedes Certified to address the issues. I am terrified to drive the vehicle, and it stays parked in the garage
