general problems of the 2008 Infiniti M35

My wife and I purchased a 2008 Infiniti M35x which is still under a warranty from Infiniti and was inspected prior to us taking ownership. I drove the car and after two days I noticed the car pulling hard when changing lanes on the highway. It did it multiple times during a 30 minute trip. I again drove the car today and noticed the issue again. I have owned over ten cars in my life and none have had this steering / lane shifting issue like this. I have also had cars with tires with extreme wear and cars in desperate need of an alignment and still I never experiences pulling in the steering wheel like this. My wife also had a passenger drove the vehicle and both noticed it on a separate occasion. I have two children and am now concerned for their safety. Please look into this matter along with any other complaints associated with steering issues with Infiniti model M35, M35x, m45 and m45x from 2006 to 2010. It is my understanding that many complaints have been submitted with little to no effort to informed concerned drivers/owners of any progress or lack there of for possible recall for or around this extremely dangerous steering issue.
