Review of the 2001 Infiniti QX4

  • A capable and luxurious truck. But so is the less expensive Pathfinder.

  • Safety
  • Pros

    Powerful V6 engine, advanced four-wheel-drive system, Infiniti warranty and service experience, excellent on-road manners, optional on-board entertainment system, available heated rear seats.

  • Cons

    Lacks sufficient tires for hairy off-roading situations, rear seats could use more legroom, some interior parts and pieces aren't refined enough for an Infiniti, navigation system hard to navigate with teensy-tiny control buttons, most of what makes the QX4 worthwhile is optional on a Nissan Pathfinder.

Simply admirable.

Vehicle: 2001 Infiniti QX4 4WD 4dr SUV (3.5L 6cyl 4A)

Pros: The reliability of Infiniti. (engine/transmission never let you down) The classic design. (never get tired of the look) The quiet city cruiser. (car-like luxury-smoothness) The able muscle on demand. (whenever necessary @240hp) The attractive interior. (quality leather all around) The choice engineering. (switchable Auto-2wd-4H-4L system) The convenient features. (4 seat heaters/2 auto seat adjustment) Cons: The gas guzzler. (15-17mpg) The tiny legroom in the back. (not easy to get in/out as well) The rust issues underneath/fender areas. (questionable building quality?) I live in a rural area where it's 60%highway and 40% off-road driving.

Vehicle: 2001 Infiniti QX4 4WD 4dr SUV (3.5L 6cyl 4A)

170,000 kms and the only repairs have been engine coils at 150,000 ($900.) emissions sensor (2 @ $150 each) and air mass sensor ($300). The machine is excellent to drive in all conditions. The 4x4 system works very competently in snow and mud. The vehicle is well appointed, powerful, quiet and smooth. Extremely reliable. Poor fuel economy & premium fuel Cramped back seat (legroom) Poor rust resistance ***** Anyone considering one MUST insist a shop remove the plastic covers over (esp. rear) wheels. EASY. A perfect looking vehicle can have BAD rust issues behind these Must spray inner front fenders and under front of hood. These areas rust from behind & will ruin vehicle

Bought new in 2000, still

Vehicle: 2001 Infiniti QX4 4WD 4dr SUV (3.5L 6cyl 4A)

I bought this car new in June of 2000. I owned a 1998 Qx4 which lacked power so the added 70 horsepower was a much needed improvement. I expected to keep it 10 years, but it at 12 years (155k miles ) and it hasnt given me a reason to get rid of it. I've kept the scheduled maintenance up on it, and the only thing I've had to do outside of that, was replace items that would normally need replacing, like brakes, shocks, etc. I got my money's worth on it. Pros: Very reliable. Does good with towing, towed 4 sportsbikes from AZ to Cali and up and down hills didnt notice any drag. Aged well for the most part, still quiet, still comfortable, nothing leaking. Cons: Not the fastest SUV out there

Unibody rust

by on
Vehicle: 2001 Infiniti QX4 4WD 4dr SUV (3.5L 6cyl 4A)

Right side unibody rusted out - the engine and front differential are connected to the frame which cannot effectively be repaired. Extreme safety hazard. If the unibody could be repaired, it would be temporary and pose a safety hazard for the next buyer and potential liability for the seller. Infiniti refuses to assume responsibility. Infiniti has repaired the driver's side strut tower housing, but does not acknowledge sever unibody rust. Dealer indicates other owners have same problem.

Rust machine

Vehicle: 2001 Infiniti QX4 4WD 4dr SUV (3.5L 6cyl 4A)

The QX4 has been very reliable for me, but it's not my everyday drive vehicle. Ride is real rough in the back and the cabin is a bit small, but at the time that i purchased it, there were not a lot of options in mid-sized SUVs. For a vehicle that mostly sits in a garage, around 6 yrs old it has had a lot of rust issues, mainly behind the fender flares and the running board. Infiniti would not do anything for me and wanted $1100.00 for new running boards. So I had a body shop redo the metal for the running boards for around $200.00 each. I do think I will by infiniti again, because they did not stand behind the rust guarantee. A $40,000.00 vehicle should not have rust that much so soon.

Why did they stop making

I am a very particular buyer and I have to say my QX4 has exceeded all my expectations! I cannot say enough about this vehicle! Start with the engine, 240hp will move; no traffic conditions will deter you from going where you want to go! The 4 wheel drive system is excellent as well, just a click of the dial and you are good to go. It handled flawlessly last winter in a heavy snowstorm, while other cars on the road were crawling along at 25mph, I was instantly up to 40mph and felt like I was on dry pavement. Very confidence inspiring! The Infiniti gets looks everywhere I go and there's not a lot of these on the road which makes it even more unique! I love this SUV! Buy one, you'll thank me!

What's New for 2001

For 2001, the QX4 gets a substantial power boost from a brand-new V6 engine. Cosmetic updates include the addition of standard xenon high-intensity headlights, revised exterior styling, new alloy wheels and a more upscale interior. A navigation system is available, as is an onboard entertainment system. A less costly 2WD model is offered for the first time, and Infiniti's signature analog clock has been added to the dash, along with electrofluorescent gauge illumination.
