My first Infiniti and I'm very pleased with my choice of a Q 40. Fast, excellent handling, comfortable, user friendly/intuitive controls, fun to drive, and very affordable for this class of car. Great exhaust note; brings a smile to my face every time I get in the car and start it up!

The Infiniti Q40 is really what used to be the G37. The car handles crisply and when you accelerate you'll think someone snuck a V8 into the engine compartment. It does 0 - 60 in about 5.5 seconds. My previous Infiniti was a G35x, also an excellent car but with under-specd brakes. The Q40 has fixed that issue nicely. Although the car is great fun to drive, I decided to sell it and buy an EV. when Covid related stay-at-home behavior resulted in unusually clear Salt Lake Valley air, I could see the impact of automobiles on our air quality. To my happy surprise, my EV is as much, or more, fun to drive as the Q40!

I sold my vehicle as of May 20221. the new infiniti Q50 3.0t was purchased in late 2018 replacing the 2015 Q40. Although I do miss the Q40 excitement, but this Q50 i smoother ride, fast and more comfy designed for a longer ride and driving.

I read the bad reviews here on this site about this vehicle. Don't be fooled by them. They are quite ridiculous. This is a great vehicle in all categories except technology, and I'm really only saying that because the USB to the audio system is Apple proprietary, so no using your android phone (very disappointing). Other than that, great car.

Best car I’ve ever Owned

I have owned my 2015 Infiniti Q40 AWD since 35k miles in 2018 and I’ll tell ya something, if you take care of it it will last you a long time. I now have 218,460 miles on it and still drives like gold. I have only had 2 small coolant leaks, normal brakes and rotors replacement, just now changed my front lower control arms, and had an issue with my valve body which I also changed a few months ago. Other than those issues I have not had any problems. Drives amazing, super fast even at 218k miles. A lot of complaints about this car, but if you use premium gas at mobil or shell, get regular full synthetic oil changes, and keep up on the maintenance you will truly receive the best performance possible for as long as you want. This car online says it will only last 200k… I’m at 218k. Let’s get it to 300k!!!

I absolutely love my Q40 ! Seriously fast and handles extremely well . Have spoken with numerous G37 ( same car ) owners and invariably they report no maintenance issues . I even took my Q40 to the local drag strip and turned a very respectable 13.8 ! Wanted an Audi but so glad I bought my Infiniti instead !! 👍👍

I am a proud owner of 2 Infiniti q40 and love everything about my babies most people hate the engine noise at a high speed but honestly that what makes driving sports cars funnier. If you can’t handle that noise I recommend you to buy Honda Fit and enjoy it. The one thing which must be done and forgotten was the rim size at least they must have to come with 20-22’ rims coz when you hit bumps you feel how the rim size is smaller for the car, beside that I recommend everyone to give it a try.

Don't call this a luxury car

I have owned my 2015 Q40 for almost 2 years now and it is the most disappointing vehicle I have ever owned. I thought I was buying a Luxury vehicle as it as touted as one and the price matches or exceeds other comparable small Luxury sedans. The only upside is that the car does have a good amount of power and is quick but other than that really has nothing going for it. The interior is very cheap with plastic everywhere and everything squeeks and already seems to be falling apart. Technology in the car is reminiscent of a vehicle from 2000, the lcd screen looks horrible and barely has any features or control over it. The gas mileage is abysmal, I do about a 50/50 mix of highway/city and I have never exceeded 15.5MPG! My last car was a large four door sedan that weighed almost 1500lbs more and was from 2004 but it got around 19MPG. The Infiniti dealer network and support from Infiniti USA is just downright horrible. Purchasing the car was not made easy at all, and I cannot even get a response from Infiniti when trying to contact their support. If you are looking for a true Luxury vehicle and a Luxury experience steer clear of Infiniti as pretty much any of the other Luxury brands will give you a better product for a better price.

2015 Infiniti Q40 AWD causes me tinnitus and heari

I bought this new 2015 Infiniti Q40 AWD from Beshoff Infiniti (San Jose) on Feb 28, 2015. After driving this noisy car for three months, or about 3000miles, I started having ringing in both ears (tinnitus). It became more and more obvious after I drove this Q40, and I have trouble to sleep since then. I also start losing my hearing in both ears, especially for the low voice from a meeting in a group or in a noisy environment, or someone with bass voice in the phone. I have contacted Beshoff Infiniti in June 2015 when I noticed the tinnitus caused by the noise. They refused to take the car back with full refund and claimed that it’s normal car noise. I took my doctor’s suggestion to wear earplugs when driving this Q40 since then. After another 6 months of driving (total mileage is 10,000miles now), the tinnitus and my hearing didn’t get better, and it’s boring me a lot, both in my life and work. I contacted the dealer and the car maker again this month. They asked me to do a second road test and still claimed that it’s normal road noise. But this “normal” noise is killing me and I don’t think I can drive this car anymore. Because the dealer and Infiniti refused to help me with the problem, I did some noise tests and analysis myself, to figure out what’s going on. According to the result from Adobe Audition CC, a professional audio analysis software, the noise mainly from 100-400 Hz, that is the low frequency noise not sensitive to human being. This means, even if the driver didn’t hear the noise, the energy carried by this sounds will still go through the ear and damage the auditory nerve cells without immediate impact. The symptom is, you may not hear a loud noise (at 6000-8000Hz), but your ears are in the pain. The low frequency noise of this Q40 AWD carried much higher energy than another model made by Infiniti, the Q50, at this range. This indicates that the company has the technology and capability to reduce the noise, but they did not apply it to Q40 for some reason. I am in the progress of negotiation with Infiniti regional affair manager now. Infiniti remains to claim it’s the normal noise, and because it not the defect on any part of the vehicle, they cannot repair it or give a full refund as I requested, neither the compensation to the health damage on me. With no concern on the fact that this noise already caused severe and permanent health damage to the customer, Infiniti refuse to recall the cars and investigate the potential harm of the noise to the customers. It’s always difficult for individual to negotiate and reach desired outcome with the big company. So far, total 8574 of Infiniti Q40 were sold in U.S. since Jan 2015 ( Infiniti sales stats: http://www.goodcarbadcar.net/2011/01/infiniti-g-sales-figures.html, the sales dropped from 1000 to 38 by Nov. 2015 ). All these customers may suffer from the same noise. Some of them may have family members riding with them, including children. As a Ph.D. in Biology, I am aware that the auditory nerve cells are the only type of cell that cannot regenerate in human body. Once you lose the hearing, you lose it permanently. The public should be alerted that there is potential risk to drive this car, for both the current Q40 owners and the potential buyers. If you are the current owners of this model of Infiniti Q40 and have the same problem with it, please contact Infiniti regional affair.
