Example complaints

Engine: “Fuel smell coming from the vehicle when parkied in the garage. Has been check out twice. 1 st time Infiniti could not find any issue, but told me they were looking into it under engineering review. 2 months later after living with the smell brought it back they had a Infiniti engineer look at it. Now they are telling me they acknowlegde that there is a issue with the crank case ventalation system. Still no fix waiting on engineering review to come out with new bulletin could take up to 3 month. The smell of gas in my garage is a health hazard to humans. …”

Condensation was so severe that water was actually dripping from my windshield onto the dashboard and dripping from the sunroof onto my seat. …”
