Consumer Reviews for the INFINITI QX50
Read recent reviews for the INFINITI QX50
Almost the perfect all-around vehicle
Doobster6, 12/29/2020
2017 INFINITI QX50 4dr SUV AWD (3.7L 6cyl 7A)
I had suffered for years with the exceedingly high annual operating costs of off-warranty European cars, especially BMWs, which are the worst. Being newly retired I wanted a vehicle that was satisfying to drive but wouldn’t cost arms and legs to keep on the road. With one glaring exception, this specific model-year compact SUV is that car.
THE BAD:
Gas mileage is mediocre at best. I see … 18 in non-highway driving and no better than 29 highway, and these figures are achieved only under a somewhat sedate driving style. Anyone pressing the right pedal hard enough to enjoy the awesome 325 hp V6 engine will see that drop, and by a lot! These days mid-sized SUVs get better mileage than that, although they can’t boast the power this car has.
Mixed Tech. While its NAV system is still useful (it was WAY ahead of its time when first introduced in 2007) it is not WAZE, which I still use. But it lacks Apple car-play or Android integration, so you’re stuck having to use the smartphone when modern cars would display WAZE on the car’s own screen.
THE GOOD:
This is a much longer list!! First of all, this was the last year for this model built on its original RWD architecture and the car’s handling match my 2008 BMW 335xi. This is abetted in my specific car which is a ‘fully loaded’ model that has the optional 19” wheels. But unlike that BMW, ride quality is also superb, matching the larger BMW 530xi I also once owned. I’m not sure how Infiniti blended both handling and ride into one car but they did. I prize chassis dynamics above all else and this car does it all!
The engine is awesome!! No turbo-lag in this naturally aspirated engine! It does have variable valve timing and lift and so it can re-tune itself to be anything you need it to be. It produces 325 relentless horsepower that pull like a freight train, falling just a smidgen behind that aforementioned 335xi. It’s fierce acceleration is surprising and almost frightening as it seems to accelerate harder the higher the revs rise. And it has no turbocharger(s) that will eventually fail and be very expensive to later replace. This VQ series of engine produced by Nissan have won awards for many years owing to their stout horsepower and reliability.
Interior space is more than adequate. A 4” chassis stretch in 2016 added rear seat leg room that allows 6+ footers to ride comfortably in this car. The seats are well formed and comfortable. A keen eye will notice that the bottom seat bolsters are smaller near the center console, so that a hand can fit between them to retrieve the wallet or sunglasses that just dropped there. This is a small but thoughtful detail that you may come to appreciate many times! Behind the back seats you have 18 cu ft of space; as much as any full-sized sedan’s trunk but fold the seats down and now you have 50 cu ft. This increases the utility of this vehicle way beyond any sedan you might choose to replace with it.
Real buttons!!! Modern cars have one or even two touch screens that bury common functions under several layers of screen menus. This car has ‘old fashioned’ radio volume and tuning rotary knobs, as well as six station buttons that I frankly prefer. Many other screens can also be instantly accessed via hard buttons conveniently placed in front of the display.
Modern safety tech! Being fully loaded, my car has the tech package which includes adaptive headlights, Bird’s-eye view surround camera, BLIS, LDW, LDA, FCA, FCA, Rear traffic cross alert and adaptive cruise. While some of these can sometimes be annoying, they are always a safety advantage.
Great interior look and materials! You will know you are not in a Honda or Toyota. It is a premium car and looks and feels that way. Chrome trim on the outside completes the effect.
AWD. Infiniti has improved their intelligent AWD over the years and it nearly matches Audi’s Quattro in responsiveness. Yet the car remains a RWD vehicle when AWD is not needed, improving handling and cornering.
In short, this is the best all-around vehicle I have ever owned. It combines the best features of many of the European cars I’ve owned with better utility and adequate technology. I love driving it as much as any car I’ve ever owned (well maybe not the stick-shift CTS-V!). Only the relatively poor gas mileage keeps me from giving the car a full five-star rating. Nevertheless, it looks like something I’m going to want to keep for many years to come. It does it all, does it all well enough for my needs!
Update 7-29-22
Still holding firm on all of the above. That said, gasoline prices have me side-eyeing SUV hybrids, although limited supply and high prices will likely keep me in the Infiniti for years to come, especially since I drive so much less now that I’m retired.
December 30, 2022
No real changes to opinions or future plans. Still love driving it every day, and now that gas prices are back down (and dropping) my interest in hybrid SUVs has dropped in concert. I’m only at 46k miles at the moment, relatively nothing for modern cars and so have many more years of high-satisfaction driving ahead. My wife’s car, the 2019 QX50, while an entirely different car based on a FWD platform, might be the only model I might wish to replace it with. What Infiniti really needs to do is appropriate some of the hybrid/electric technology from its parent company Nissan to offer a more gas-efficient model that’s still an Infiniti!
