I've had my 2006 350Z for about a month now (bought it used from a Porsche dealership) and I've had no problems whatsoever. I brought it to my local Nissan dealership for the routine 7,500 mile maintenance. When I got it back, and driving it the rest of the day, I noticed the steering is significantly looser than it was before the maintenance.

It wasn't low on PS fluid before the appointment, plus I've driven a few other Z's that all have the normal tight steering. I've contacted the dealership and am awaiting a response.

Has anyone else experienced this or have any suggestions?
