I have the same car as yours
I remember when I picked up the new car from the dealer, before I even drove out the lot the check engine light came on
The fuel sending unit was faulty and the dealer had to order the part. What an experience for a new car! I had many subsequent trips to the dealer about electronic issues. I hate to say it, but you will experience more the same
Where as my G35 is trouble free for almost a year.
