2003 Infiniti QX4 4WD 3.5L V6 from North America
A great SUV, if you do not anticipate having anyone in the passenger seat
Not a whole lot. But there are some common problems associated with this vehicle.
The catalytic converter near the exhaust cracks at the seams - needs to be welded.
SES light comes on - in my case it is either the fuel cap or the post cat O2 sensors (apparently this is a common problem, and replacing O2 sensors will help, but it will occur again unless the ECU is programmed).
The BOSE CD system will keep skipping CDs after a couple of years, and installing an aftermarket system is not that easy.
The IVIS - Infiniti vehicle immobilizer system is very sensitive to interference from other RFID sources (access cards etc.). It intermittently fails to recognize my key, and then starts working again.
Brake pedal travel is a common complaint with Pathfinders and QX4s; needs getting used to.
This is a very good looking sturdy SUV, and a great second hand buy. It is basically a luxury Nissan Pathfinder, with an auto (AWD) mode, although the AWD mode is not that effective.
Love the cargo space, and the 3.5L V6 seems responsive.
Compared to a Lexus or Acura, the suspension is stiffer and the cabin noise is higher.
My biggest regret with this vehicle (which I should have checked when I bought): The rear seating is very uncomfortable, there is hardly any headroom and the seats very high. If you plan on using a car seat, DO NOT BUY buy this SUV. The passenger door entry is narrow and the seats being high, moving a toddler in and out of the car seat is not a pleasant affair.
Would you buy another car from this manufacturer? Yes
