2001 INFINITI QX4 consumer reviews

Good Mostly reliable vehicle. Poor gas mileage. the O2 sensors have a tendency to go bad. Solid vehicle and very comfortable. The headlights can be pricy to replace. Used only. We have over 178,000 miles on it and still going strong.

This has been such a great ride for me. Perfect size. I got it at 40k and currently at 205k. Still runs great. Wish I could find something similar to buy as mine is on it's last legs. Trying to keep it going, but it needs a new rear main seal and rack and pinion which might force me to retire my favorite car. The engine still runs smooth though. Pros: Been very reliable. Comfortable seats Great medium size Cons: Poor MPG O2 sensors go out Bose 6disc change is a defective piece of junk

Bought in 2005 till present. Over 130k miles put on it myself (183k total). O2 sensors are the worst problem. Prepare to fix them every 18 months. Seat motor went right away. Rough ride, invest in good springs and shocks. Now the (possible cause) motor mounts needs to be replaced, because the engine shifts when the gas is pressed or released. Great truck for 8years though.

We bought a used 2001 Infinity QX4 and were thrilled with the deal we got from a private seller, seemed like a slamming good value. It had everything we wanted, 4wd, leather heated seats, xenon headlights, a very well tuned motor and the transmission is the creamiest smooth of any car I've owned. The tolerances are tight on this vehicle. It was purchased from a 1 owner older woman, who was a real estate executive and she had all the paperwork for all the maintenance that was done at the Infinity dealer no less. This was our impression for the first 6 months. We bought this vehicle based on reviews by "a leading consumer magazine" (wink wink) supposedly one of the "best used vehicles" when it comes to reliability. Well, maybe we had a lemon but everything went to h*ll in a handbag within a year. First, the 6-disc Bose stereo quit working, then the drivers power seat motor went out, then the passengers drivers seat motor went out. OK, we could get along without these creature comforts for the time being without paying an arm and a leg to have them fixed. Then went the O2 sensors and of course 1 went one month, the next one the next month, and the third one was maybe 3-4 months later (there are about 4-5 total 02 sensors on this vehicle). The last straw was the head gaskets at 80k miles. In order to work on this "race inspired engine" they had to completely remove the ENTIRE engine to remove the heads. This was per the Nissan (Infinity) dealer who was going to charge us $5k for head gaskets, but also confirmed by a local mechanic (who charged us $3k). The irony of all this is we traded in our "recommended used vehicle" for a 2003 chevy suburban which was a "used car to avoid" per the "leading consumer magazine." We bought the Suburban with 50k miles on it and now have 230k miles on it and have not spent more than $1k in repairs. I am not biased for domestic cars, and have owned many domestic and foreign cars. If you are thinking foreign, I strongly encourage you to look at Lexus or Acura vs. Infinity! I acknowledge there is always the luck of the draw. IMO, stay away from any Infinity's unless you can afford to fork out the cash when it needs repair or can afford to buy a new one with a bumper to bumper warranty and even at that be sure to get rid of it once it's out of warranty!

The only bad thing to say is O2 sensors, and rough in the rear. Other than that, this is a GREAT suv. I have 160k miles now, and I put over 100k on it myself. It's a stylish car that doesn't need more than the basic maint. (oil, tune up). Work horse, I load up at HDepot and still have room left.

This is one of the best vehicles out there; not too big, not too small. Bought this used; had one owner previously. Great vehicle for the money. This drives like a Big car in a smaller frame and has power too. I love it!

We bought this 2001, Infinity, Qx4, in January 2012. Has a great road feel. Has all of the appointments of an expensive car. Paid $7,000. Rides like $30,000. I highly recommend the car.

I purchased this car about 3 months ago from a dealer for $7k. For a 10year old car, it has been kept well, except for some rust from up north. I had to have the running boards reaffixed as the piece holding them was all rusted. There was some rust on the hood, which the dealer took care of. I notice now though that there's quite a bit of rust underneath which is giving me an uncomfortable feeling when I hit a bump that I could be in trouble with the chassis. I need to replace a belt, screeching, and change out the fluids, but otherwise, it's been great. My two 100 lb dogs have plenty of room in the back with a human family of 4. I haven't tried hauling anything yet, so curious on that since I've heard mixed reviews on it's ability. Tons of gadgets-navigation, video (vhs), 6 CD changer, electrical outlet under the seat, etc. My one big gripe with this car is the gas mileage. This baby is guzzling like crazy....

This was one of best vehicle purchases I have ever made. I had a 95 Pathfinder and loved it (still going strong I might add-passed it along to a family member), tried an '00 Jeep Grand Cherokee in between and couldn't stand it-no comparison-and thankfully moved up to the QX4. The QX4 is very reliable, gas mileage is much better than the Jeep, it has a much smoother ride and drives more like a car yet you have the features of a truck, the height, and the 4X4 quality. I now have over 100K on it and expect it to go another 100! Maintenance costs have not been excessive at all and no problems. Definitely recommend it for a dependable vehicle that is comfortable and has great features.

I recently purchased the 2001 QX4 because I wanted a luxury smaller SUV. That is exactly what I got. It has all the "fancy" features, rides great and has a large enough engine to pull my 19 foot boat. I especially enjoy the inside with the heated leather seats, Bose audio, etc.
