First of all I'm 22 years old, and I have never owned an SUV before. I've toyed with nothing but sports cars, roadsters and rally cars but I fear it's time to enter new ground. I had actually originally been looking into a 2006+ Honda Civic, but I wanted something bigger and perhaps power to all four of my wheels

My current car is a G35 coupe...and as much as I love the car, I'm incredibly displeased with it. Not with its performance, I could keep this car forever. But for its reliablity. This car has had problem after problem since it hit 50K miles. So my question to you is, do any of your Pathfinders (2005+) exhibit these same problems? They are as follows:
Transmission rattle
Oil leak (several occasions)
Window motor failure (both)
Window regulator failure (both)
Gauge displays "slip" "brake" "VSC off" and all other kinds of misfires
And one other BIG question, how is the overall gas mileage? Not for an SUV...in general. I'm not impressed at all with the mpg on my G35, and I believe the Pathfinder gets the VQ35 also. I read the Pathfinder gets around 15 city/21 Highway...is this true?
Thank you to anyone that has done their best comprehending this, and especially to anyone that has an answer for me. Just do me a favor and be brutally honest about your experiences with your Pathfinder.
