As concerned Ford Explorer owners search for replacement tires, I found myself helping friends clean out a garage full of old car parts.

The reason car enthusiasts hord parts is so that when something breaks, the collector will have a spare on hand. Although these friends (aka the troublemakers) do have extra tires, some of which I hauled, they don’t have any extra Explorer tires. This is despite owning an Explorer.

Of course, after an afternoon of hauling dusty old boxes full of enigmatic scraps of rubber and metal, it was comforting to climb into the cushy luxury of Infiniti’s newly-reworked QX4 sport utility vehicle. This vehicle was way too nice to haul dusty old car parts.

The basic chassis is carried over from last year, as is most of the bodywork. But the grille and bumpers have been reworked. The most notable change is the high-intensity discharge Xenon headlamps up front. But this subtle change shouldn’t hide the bigger change underneath.

For 2001, Infiniti ups the power ante with an all-new 3.5-liter double-overhead-cam V-6, good for 240 horsepower and 265 foot-pounds of torque. This is a huge improvement over the 3.3-liter single-overhead-cam 170-horsepower mill that previously resided under the hood. Power is effortless and comes on strong from low in the rev range. It comes on smooth, with a solid exhaust note to remind you that you’re riding in a truck. But it’s not objectionable.

Power is fed through a four-speed automatic transmission to an all-wheel-drive system. The system is derived from the all-wheel-drive system used in Nissan’s Skyline sport coupe. It works invisibly with a simple twist of a dash-mounted switch, delivering up to 50 percent of the vehicle’s torque to the front wheels. A low range is included for low-traction situations. For the first time, a two-wheel-drive version is available.

Handling is quite adept for an SUV. This was always a QX4 strong suit, but the added power makes it more apparent. There’s an excellent balance between a comfortable ride and capable handling. Body lean is minimal, and there’s little front-end dive when braking. There’s some tire noise, but otherwise, the car is quiet. This is one SUV that has terrific on-road manners.

Overall, this is one the best handling SUVs I’ve driven in a while.

The interior sees some change, as well as the exterior.

Infiniti warms up the interior with generous doses of leather and imitation birds-eye maple. With a new analog clock at the top center of the dash, the interior does have a more opulent feel. The leather is of a better quality than previous samples.

The dash has easy to read gauges, although as is typical these days, information is limited to fuel and temperature. The test vehicle has the optional GPS system installed, which mired the otherwise ergonomically-correct interior.

Like all GPS systems, this one was distracting. The visual presentation is crudely executed, again, common to most systems o f this ilk. Uncommonly, this map was presented in a 3-D grid and didn’t seem very accurate. Worse, one has to use the GPS screen to adjust the climate control. Skip this option.

The center console had plenty of space for beverages. The storage bin had loads of space. A console and outside temperature gauge is mounted just above the rear-view mirror. Heated seats, auto up/down windows, seat position memory were all included. Despite the pretense of luxury, there were a couple items missing that are common in luxury vehicles. There’s no auto-dimming rearview mirror, rear seat climate controls or mini-computer to gauge fuel economy and other miscellaneous info.

The low-mounted front seats proved comfortable, although long-legged drivers will find leg room on the short side. Raising the power-activated seats doesn’t help, for head room is tight. It’s even worse in the rear seat. I didn’t fit. This cabin seems very tight for the size and mission of the vehicle.

Cargo room is ge ous and like any SUV the rear seats fold flat to provide 85 cubic feet of space. The CD changer is located in the cargo area behind a door. A piece of velcro keeps it from flopping about. However, there’s no provision for the CD cases, which must be carried elsewhere.

Fuel economy was about the norm for an SUV, 16.5 mpg in mostly city/suburban driving. Inifiniti recommends using premium fuel.

Yes, this quiet capable SUV was way too nice to haul old Packard parts. But it was nice enough to haul my aching body home to rest up for next week.

There’s still half a garage to empty.

  • Awesome car. Highly recommend buying.

    I bought mine in 2012 with 156,200 miles. I did regular maintenance oil changes, tires, etc. Had to replace an alternator in Jan of 2022. I loved my car until I was hit by 2 cars a pile up on garden of the gods rd in Colorado Springs, CO. Some 18 year old idiot and the person behind him hit me. No injuries to me other than a little neck pain. He just totalled my car July 3rd, 2023. It was going strong with 246,980 miles. I wasn't planning on ever getting rid of it. It looked as good as the day I bought it. The best $6000 dollars I've ever spent. Still dealing with his insurance. It's a good thing he was driving the company van. He totalled the 2017 Toyota Sienna. A total piece of s.......t in my book. Not built very well. The front was all smashed in. Oil and fluid everywhere. My bumper saved me. He hit me with such force that he bent the frame. That's the only reason why I can't get it fixed. I will be keeping this one for parts and eventually buying another one. Oh, mine is still drivable we just cut off the bumper because it was rubbing against the tires. NO MECHANICAL PROBLEMS WHAT SO EVER. Drives as good as ever. Just doesn't look pretty. I WOULD DEFINITELY RECOMMEND BUYING THIS CAR CAN'T SING ENOUGH HIGH PRAISES ABOUT IT.

  • Bought it for a VERY low price.

    I bought mine for $400 but did three times that amount of work on it. They are prone to having the Nissan Death Wobble ($900+ fix) always check by bringing it to a mechanic and ask them to check the stabilizer bars. After getting all the problems fixed tho, smooth ride, very reliable.

  • 311,541 miles and counting!!!

    Simply the most reliable car I've ever owned. I am the 2nd owner and bought this car in 2011 at 134,000 , give or take. My work has me commuting all over, and in a mere 9 years I have racked up another 180,000 miles. In the past, I would consider selling a car approaching that 200,000 milestone. But this baby is still running as strong as when i first purchased her. Nope...can't let her go now. She's been too good to me. If you maintain this car, (I run a 5w30 synthetic blend w/mid-grade fuel), it will run forever. I'm looking forward to the next 300,000...happy anniversary, baby!

  • Never let me down but that factory stereo is a tur

    Yes this infiniti has met all of my needs and then some , plenty of power , i live in new england and 4wd is a must and the 4wd is so simple no hubs to lock and HI-LO never fails knock on wood and goes through any amount of snow .. Only complaint is the 1st start of the day you have to keep the foot on the throttle until it warms up , must be a bad TPS but I can live with it , also love the fact its a timing chain engine not belt and engine is extremely quiet and smooth as silk . I would strongly recommend purchasing one

  • Great vehicle

    This is a great mid-size SUV. Plenty of bells and whistles for its age, good power, great ride and expected gas mileage. I put my 16 daughter in this vehicle as her first car and she loves it. I feel great about how well she is protected.

  • 255,000 miles and still runs great

    Our 2001 Infiniti QX4 has been a very reliable vehicle for 17 years and has never broken down. The engine and transmission have been trouble free because of a routine synthetic oil changes, There have been some repairs that have been performed including: O2 sensors. MAP sensor, radiator, valve cover gaskets, starter and a few other minor repairs. Hope to get 300 k miles or more.

  • My favorite ride so far.

    I own a 2003 QX4 and just love it. It had 14K on it when purchased in 2007 and is currently at 96.4K. It has been so dependable and I intend on giving it to my daughter when she is old enough to drive in a few years. Will definitely get another Infiniti!

  • Best car we have purchased.

    This is a great value. All luxury SUV. Was top of the line in 2001. We hate to see it go. The main reason we are selling is the car can't be flat towed behind our M.H.

  • A lot of bang for the dollar...

    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.

  • Still have it, 200k+ miles

    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
