2001 Infiniti QX4 Consumer Reviews

Unibody Rust

Vehicle

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

Review

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)

Review

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 these?!

Vehicle

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

Review

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!

My experience

Vehicle

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

Review

Fun little rig to drive. The MPG is a tad low but the pep somewhat compensates for it. I bought it with 90K on it and for the most part it is in new condition. My biggest complaint is with the Bose/Clarion 6 CD/Cassette stereo. I had the car 4 months and got what is known as the dreaded err 2 message on the CD screen. With a bit of investigation I found this is a very common problem. This problem is peculiar to the 2001 model. There is a plastic gear in the CD changer that strips out. I have read of dealer quotes to $500 to fix this.

QX4 should be brought back

Vehicle

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

Review

When I purchased the 2001 QX4, there were not many car based SUVs - QX4 is a truck based rear wheel drive vehicle. 4WD was an option. The differential & drive shaft needed for rear wheel drive adds weight - for that reason gas consumption is a bit higher compared to contemporary non-SUVs. 2001+ models have the killer look - personally, I prefer it over the X5s and of course RX300 and M-Class. The front bezel and the wide three-spoke aluminum wheels (for 4WD trim) are both unique. The 4WD trim came with adequate and stylist standard features - Xenon HID head lamp, sun/moon roof, 6CD Bose, electro-fluorescent dash, everything-power, leather, simulated wood-trim ...

Electrical problems with our Q

Vehicle

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

Review

We thought this was one of the best values on the road as we previously had good experiences with Nissan Pathfinders. Unfortunately, electrical problems have ruined an otherwise good ownership experience with our QX4. We should have seen the early warning signs. Had to replace the entire radio/CD player at 25,000 miles (under warranty), have replaced batteries once a year for a non start - completely dead issue - something creating a slow draw from the car when it sits parked. The longer it is parked, the more chance it won't start. Now that we're out of the warranty, CD player is again not working and the car needs to be jumped once a week. Take it to the dealer and no problems can be found.

Worth the $

Vehicle

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

Review

I bought this vehicle used with 60,000 miles on it about 5 years ago. It drove great at first (even though the check engine light mysteriously came on, then off). Now that it's getting close to 100k mi, it needs some work (transmission solenoid kit & mass airlow meter). Also, the 6 disc cd changer has had problems since the day I bought it. Overall, it has been a very dependable SUV and handles great in bad weather.

Beauty Without Brains

Vehicle

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

Review

Although this SUV appeals to my senses it has become a disappointment from an owners view. I am a small (5'4") female but find this suv cramped both front and back. Driver's seat is small and uncomfortable on long drives. Back seat has no head room for taller people. Gas mileage is poor (wish they had not made it a 4wd I have yet to use it). Having mechanical problems 1120 miles. "Check engine soon" light comes on and auto will run like choke is stuck . Later it will correct itself until another time. I expected to get 200,000+ from an Infiniti with routine maintenance without any problems. Needs true engine reliability. Expected more from an Infiniti.

Best SUV in it's class

Vehicle

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

Review

Before purchasing my QX4, I test drove every SUV in that class. The QX4 is more powerful, but at the same time super luxury. You feel the class as soon as you step into one. The wood trim, analog clock and heated front seats are just a few items that make the QX4 a comfortable ride. The 4WD is great in the snow; I was able to outmaneuver a friend of mines H2 Hummer. Have had it for over 2 years now and can’t image life without it.
