it all started with a flat tire and the PSI light lite up on board, had the flat tire fixed and took car to shop where I got the tires replaced, within a year into ownership I was told that all four tires needed to be replaced due to them being bubbled GM replaced them for free; took car to (Just Tires GM recommendation) with free tire balance and rotation and they also did front end alignment, after that lights was still on and shop rep said to drive the car a couple miles and it would reset itself so I did and still light was on drove to church on 4 lane hwy 85 n bound and I felt a slight tug on the right passenger side of the front of the car and decided to move out of the lane behind a 18 wheeler as I attempted to move out of my lane the car made a sudden jerk back in the lane which i was in and the wheel locked and i could not control or unlock it and the car began to spin and slide into the rear end of the 18 wheeler, the sonar system was engaged and it did not respond to what it was designed to do, nor did the lane departure indicator, nor the anti braking anti skidding work as it was designed which caused the accident which lead me going to the hospital with a diagnosis of muscle inflammation. The sonar failed was illuminated on the dash. My 2014 Q50 sedan was equipped with sonar, lane departure, blind spot indicator.. it was fully equipped. I am very sure that the steering and anti braking anti skidding did not engage as it should. Infiniti will send an inspector to the totaled car and pull the black box/or chip and check out what went wrong. Waiting on the result on or after June 14 or 16 as of their decision.
