I have concerning issues with the transmission of this vehicle since purchase 8/27/2010. The transmission has major hesitation when accelerating, slowing down and with everday use(jerky feeling in city traffic) no matter what drive mode is used I.e sport, normal, eco, snow modes. Whether you pull out to pass on the freeway or,pass bicycle on a narrow 2 lane road, at residential speeds, the transmission hesitates dramatically(2-5 seconds),actually to the point I don't feel safe with this vehicle. I have taken the vehicle back to the dealer 4+ times to address this issue,contacted Infiniti consumer affairs, and was told by all, that it was "normal" operation.... Which it is not!!! *tt

I have noticed problems on multiple occasions with my m37 not accelerating when I hit the gas. While getting over into another lane to pass a vehicle my car stalled for a few seconds while trying to accelerate and I was almost rear ended by another car. Two months ago I went to accelerate on the freeway and the engine just revved up until I took my foot off the gas. My mom was in the car and she agreed that this is not normal! On two occasions I have also noticed while coming to a stop my car would jump forward but thought it was me until I saw other posts regarding this. And yes I have discussed this with our Infiniti dealer and they can't seem to figure out what the problem is. I have driven many cars and have never experienced issues like these. *tr

Sunvisor does not fold back far enough blocking tall driver's view of road. Left edge of sunvisor hits edge of trim preventing proper adjustment. Note that 2012 visors have been slightly redesigned and work properly. *tr
