I was disappointed with my 2012 infiniti m37x purchased on 1/3/2012 at infiniti. My safety was put at risk with this vehicle. I took delivery of my new m37x on the night of 1/4/2012. Upon delivery, I drove at highway speeds(65 MPH). The car was vibrating constantly, and I felt the vibrations prominently through the steering wheel. Within twelve hours of delivery, I contacted infiniti about the safety issues via email and telephone. On 1/5/2012, I brought the vehicle to the service department at infiniti. Infiniti diagnosed the vehicle and discovered two defective tires/wheels. I feel that my safety has been placed in jeopardy with this infiniti vehicle. My minimum expectation from infiniti is the delivery of a safe vehicle.
