The plastic trim on the steering wheel that is colored to match the other plastic trim in the car has cracked at the 2:00 clock position. The cracked plastic sometimes lifts when turning the wheel which I feel may cause an accident. I have not had it inspected by the dealer of manufacturer as I'm aware they won't repair it currently. There were no symptoms before it happened, it was just cracked/separated one day. Nissan/Infiniti should be required to repair this potential safety issue.
