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.
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.

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!
Comments as of today October 10, 2018: I am still driving the Q40. Lease about to expire and seriously thinking about purchasing this vehicle. This vehicle has been giving me no trouble at all except joyous ride, still exciting to drive this car. Test drove many other vehicle but hard to let go off amazing power with comfort and quality. Nothing even in higher class of car come close to this. Q40 ibring in excitment in driving and no vheicle can match it's powerfull respond and speed. The only downfull to this car is the low mileage and gasolin consumption which have to be super unleaded. But again nothing is free. Mechanically the performance have been awasome.
Pervious 2015 comments when leased the Q40: I love my new 2015 Q40 with amazing high acceleration and fast response. Driver feel safe and in full control while driving this vehicle with very powerful engine representing an extrimly fast respond which creat pure excitement and joy. The sexy design with simple elegant interior arrangeme with colors and quality used inside the Q40 with easy access to all key instruments such as navigation provide a warm comfort feeling to any driver. This powerful six cylinder engine with over 328 horse power bring with it's amazing speed with high acceleration gives a driver pure at any speed while feeling safe and in control. Driving this vehicle in any street, generate an appealing statement to all others. The engine exhaust sound clearly represent of a high quality sports car present in any enviorment. The downside is the high cost of gasoline/fuel expense specialy the recommended premium fuel. Then again it is simpley worth the cost since driving this vehicle bring joy and pleasure to any driver.
