Infiniti Q50 problems
The Infiniti Q50 is a compact executive car manufactured by Nissan for its luxury brand, Infiniti. Replacing the G/Q40 sedan, it debuted at the 2013 North American International Auto Show and went on sale in North America in the third quarter 2013 and in Europe in fourth quarter 2013. It is the export model of the Japanese domestic market's V37 Nissan Skyline.
The design of the Q50 continues to follow the designs first shown by the 2009 Infiniti Essence concept and the production 2011 Infiniti M. The Q50 is also the first instance of a hybrid model in Infiniti's entry-level model but was later removed for the 2019 model year.
First generation
Q50 sedan (2013–)
The design was based on Infiniti Essence (crescent-cut C-pillar, deep body section, asymmetrical cabin layout, interior finishes) and Infiniti Etherea (headlights, three-dimensional double-arch grille, interior finishes). The production Q50 design was frozen in June 2011, after being designed by Joel Baek under Shiro Nakamura.
The Q50 sedan was unveiled at the 2013 North American International Auto Show, followed by the 2013 Canadian International AutoShow, 2013 Geneva Motor Show (with Hybrid and 2.2d), 2013 Dubai International Motor Show, Auto Guangzhou Motor Show in China (with 2.0-liter (214PS) turbocharged engine from Daimler AG (Mercedes-Benz)), and Victoria Harbour in Hong Kong.
Early US and Canada models include 3.7-liter V6 (333PS), 3.5-liter Hybrid (364 PS), each in a choice of rear-wheel drive or Intelligent All-Wheel Drive and in a selection of trim levels, including Sport models.
US models went on sale in August 2013.
Early Canadian models include 3.7-liter V6 (Q50 RWD, Q50 Sport RWD, Q50 Premium AWD, Q50 Premium AWD Navi, Q50 Premium AWD Navi and Deluxe Touring and Tech, Q50 Sport AWD, Q50 Sport AWD Deluxe Touring and Tech) and 3.5-liter Hybrid (Q50 Hybrid Premium RWD, Q50 Hybrid Premium AWD, Q50 Hybrid Sport AWD).
The early European models included 2.2d and hybrid. Infiniti's 2.0 RWD (211 PS) model was added in 2014.
In China the 2014 Q50 3.7L was sold as an imported vehicle until production in China could begin. The 2.0 RWD (211 PS) model and the Q50 Hybrid also joined the line up.
Middle East models was set to go on sale in spring 2014 as 2014 model year vehicles. Early models include 3.7-liter V6 and 3.5-liter Hybrid, both in rear-wheel drive.
Australian models went on sale in February 2014, launching with the 2.2d diesel and 3.5 gasoline hybrid models.

Common Infiniti Q50 problems
The Infiniti Q50 is a luxury sports sedan that has been praised for its powerful engine, upmarket cabin quality, and smooth performance:
- Brake Master Cylinder and Pump Seal Failure: This issue can cause a soft or spongy brake pedal, which can be dangerous, especially in emergency situations. The brake master cylinder and pump seal may need to be replaced to fix this problem.
- Premature Brake Wear: Some owners have reported that their Q50's brakes wear out too quickly, which can be expensive to replace. This issue can be caused by a variety of factors, including driving habits, brake pad quality, and vehicle condition.
- Tires Wear Out Too Quickly: Infiniti Q50 owners have reported that their tires wear out too quickly, especially if they are driven aggressively or frequently on rough roads. Choosing a higher-quality tire brand and performing regular maintenance, such as wheel alignments and tire pressure checks, can help extend the life of the tires.
- Engine Seizure: In some cases, Infiniti Q50 owners have reported that their engine has seized up, which can be caused by low oil levels or other mechanical issues. This problem can be expensive to repair and may require complete engine replacement.
- Won't Start: Some owners have reported that their Q50 won't start, which can be caused by a variety of issues, including a weak or dead battery, corrosion on the battery contacts, or a failed starter motor.
- Car Running Hot: Overheating can be caused by a variety of factors, including low coolant levels, a malfunctioning thermostat, or a seized engine. Regular maintenance and monitoring of the vehicle's temperature gauge can help prevent this problem.
- Steering Problems: Several owners have reported that their power assist system malfunctioned, which can make the car difficult to steer or cause it to pull to one side. This issue can be caused by a variety of factors, including worn steering components, low power steering fluid, or a malfunctioning steering control unit.
- Transmission Problems: Some owners have reported that their Q50's transmission slips, shifts roughly, or fails to shift at all. This issue can be caused by a variety of factors, including worn transmission components, low transmission fluid, or a malfunctioning transmission control module.
- Airbag Failures: Recalls for airbag issues are one of the most common problems in Infinitis, along with transmission problems. Faulty airbags can fail to deploy in a crash, which can increase the risk of injury or death.
- Brake Problems: Some owners have reported that their Q50's brakes feel spongy, pulsate, or make grinding noises. This issue can be caused by a variety of factors, including worn brake pads, contaminated brake fluid, or a malfunctioning brake booster.
It's important to note that not all Infiniti Q50s will experience these problems, and many owners have reported positive experiences with the vehicle. However, being aware of these common issues can help owners take preventative measures and address any problems that may arise.

Infiniti Q50 2015
- Date Of Incident: 2024-10-23
- Date Complaint: 2024-10-23
- VIN: JN1BV7AP5FM
- Components: AIR BAGS
- Summary: Upon driving when purchased the Engine Light for the Air Bags illuminated. Upon researching the issue the problem seems to be a common problem for vehicles of this make and problem. 90% of the time requiring the owner to take the vehicle to the dealership.Since it is a trend and ongoing I wanted to report the issue.
Infiniti Q50 2017
- Date Of Incident: 2024-08-26
- Date Complaint: 2024-10-08
- VIN: JN1CV7AR9HM
- Components: AIR BAGS,SEAT BELTS
- Summary: The seat belt light went on without a passenger and the dealer decided to perform a zero point reset on the passenger seat and that resulted in a failure and now the airbag light is on. This causes the passenger airbag to not be operational. Before it was just the seat belt. They are now asking for $8000+ to replace the seat and OCS module and they said that they would cut the price by 50% but that is still $4000. The seat belt is covered by 10 year warranty but the airbag is covered only 7 year. I feel that since the seat belt was the iniial problem that it should all be covered under the warranty. Searching online there are numerous other Infiniti owners are having the same issue with the passenger seat and they are all being told that the seat needs to be replaced. This looks to be like a fauly module issue and thiink that Infiniti should be responsible for the fix. This has been happening with models from 2014-2018 two different series of Q50 models. THIS CAUSES THE PASSENGER AIRBAG TO BE NON OPERATIONAL AND FEEL THAT THERE ARE A LOT OF Q50 and other models on the road that are NO LONGER SAFE TO DRIVE!!!!
Infiniti Q50 2015
- Date Of Incident: 2023-07-16
- Date Complaint: 2024-09-23
- Crash: 1
- VIN: JN1BV7AR4FM
- Components: AIR BAGS
- Summary: I was in a car accident during the summer, I was driving at speed limit when I came out the curve the car started sliding, and I went off the road and roll over at 4 times and ended up in a ditch upside in some water, but NO AIRBAGS went off I have pictures showing so, I try to tell the dealer I bought it from Car Max and even my insurance but no one seem to care but now I found this page. I also had a police on site and no ticket was issued to me since no proof of me driving recklessly I did have a police report but I can’t find it since it was back in the summer
Infiniti Q50 2016
- Date Of Incident: 2024-09-13
- Date Complaint: 2024-09-21
- VIN: JN1FV7AP5GM
- Components: POWER TRAIN
- Summary: The car has only 50,000 miles and the valve body of the car just burnt out. I’ve done all the mandatory/ recommended maintenance and with the history of the brand I expected better quality of their product. Would greatly appreciate the accountability on this issue and some effort to fix this for the population.
Infiniti Q50 2014
- Date Of Incident: 2024-09-02
- Date Complaint: 2024-09-12
- VIN: JN1BV7AP9EM
- Components: POWER TRAIN,VEHICLE SPEED CONTROL
- Summary: The transmission Valve Assembly Control Module and Vehicle Speed Sensors have both failed. The car will not shift out of 2nd gear and cannot go faster than 40 mph. This is a safety issue. I had my car inspected by a certified mechanic and he diagnosed the problem. He also stated that that he has seen this a lot with Infinitis. I have maintained my car well but this is Not a maintenance issue. There are thousands of infiniti owners online stating that they had the exact same problem. I filed a case with Infiniti #52260861. This is a design flaw with All Infiniti cars and SUV's and it should be a Recall or at a minimum fixed for free by Infiniti. It cost me $3,500 to have my car fixed and this should be paid by Infiniti to me and all other Infiniti owners with this same problem.
Infiniti Q50 2017
- Date Of Incident: 2024-08-28
- Date Complaint: 2024-09-11
- VIN: JN1CV7AR9HM
- Components: AIR BAGS,SEAT BELTS,SEATS
- Summary: I took the car into the dealership to diagnose the reason that I was getting a Seat Belt light and they said that the guide suggested to do a zero point reset on the seat. When they attempted this they said that it failed and now the system has an airbag light on. There is no more seat belt light on now for the passanger side, but there is a hard error code for the airbag system on the passenger side. The Dealership now says the cost to repair is over $8500 when the car is only valued at $10000. I saw that there was a voluntary recall on a 2016 edition and it said that if the zero point reset should fail then the OCS module needs to be replaced, but now they are saying tha the OCS module and Seat need to be replaced. This looks to be like an issue with the model itself. The reason this is a safety issue, is that now the airbags will not work on the passenger side. This is caused by the zero point procedure that Infiniti has instructed their techs to do. I believe they are causing issues and had this not been needed then I would not have had an airbag issue. If there was an airbag issue before this procedure then the symbol was not correct and was false. It was a safety issue since the Passenger side airbag will not deploy in this case.

Great car overall! While the steering may take a little getting used to, it's worth it for the amazing technology that INFINITI has introduced with their Direct Adaptive Steering® (DAS). As quoted by Infiniti, this is a world's first technology that removes the mechanical connection between the steering wheel and tires. Plus, the 3.0t engine provides more than enough power for a fun and exciting driving experience!

This is the best driving car I've ever owned! I've driven it for a little over 5,000 miles, including a couple of long trips. The only issue I've had was when the steering pulled to the left once and to the right a few weeks later, like the front was out of alignment. But both times it was random and went away after a few minutes. I find this car to be very quick, nimble, and fun to drive. Merging into fast-moving traffic is especially enjoyable, as the acceleration will push you firmly into your seat. While the drive-by-wire steering might be an issue if you drove this car on a track, for everyday street driving it's been great. Also, the brakes are a bit grabby, but once you get used to them, they're fine.

I've leased three Q50 sedans so far. My first was the Q50 3.7L, and now I'm on my second Q50 3.0t Sedan. I really enjoyed the switch from the 3.7L to the 3.0t. It was a pleasant surprise to experience a turbo engine for the first time. The power and engine response on the 2016 model was very good, and the safety features and technology were great. However, I have noticed that the 2019 model isn't as smooth of a transition. I currently have about 1200 miles on it, so it might get better after the break-in period, but I feel there is more turbo lag in this car compared to the 2016 model. It's not as responsive. I do love the small changes to the exterior body, but there are a few things that I don't like. For example, the brightness of the blind spot warning light. There seems to be two stages for the light: one is when the BS detects a vehicle and lights up, and the second is when it starts blinking when/if you put the turn signal on. The warning light is dimmer than the blinking light. In the older models, it was all the same, which I prefer. Lastly, the front passenger seat still vibrates. In my 2016 model, they couldn't figure out the issue to fix. I was hoping the 2019 model wouldn't have the same issue, but unfortunately, it does. It's the small things that can ruin a nice car!

I bought my Q50 in mid-March as a demo with 1700 miles on it. The car was delivered in flawless condition. I absolutely adore the look of both the interior and exterior, and the car's feel and comfort are outstanding. The navigation system has worked perfectly for me, even on country roads. The interior is nicely laid out and the technology concepts are awesome. Although I wish the 'In Touch' did what it was marketed to do, I still love my car and wouldn't trade it in for its shortcomings.
Are you having problems with your Infiniti Q50?

Edmunds' full expert review has nothing good to say about the Direct Adaptive Steering option, and now I understand why. My new fully loaded Q50 Premium has Direct Adaptive Steering and run-flat tires. After driving it for over 1000 miles on mostly highways, I am deeply troubled by the rather abysmal performance, road handling, and maybe even the real-world safety of this steer-by-wire system. As of this writing, I do not know the extent to which the rather miserable run-flat tires may be contributing to this poor performance, but I suspect it may be quite significant. I will have more to say about these tires shortly. For those who may not be familiar with Infiniti's Direct Adaptive Steering (steer-by-wire), there isn't a conventional mechanically coupled linkage between the steering wheel and the front end. Rather, the system relies on an electronic interface between the steering wheel and the front end. Thus, unlike conventional steering, there is no instantaneous telegraphing and biomechanical feedback of the sensations that a driver normally feels between one's hands on the steering wheel and the road, particularly lacking the natural progressive resistance that one would normally feel as the steering wheel is turned ever more to the left or to the right. The lack of this natural sensation between the driver's hands and the road would be totally unnerving and disorienting. So, Infiniti has attempted to simulate this sensation by driver-selectable settings found within the Infiniti Drive Mode Selector app, which can be accessed by scrolling through the apps on the touchpad. After tapping the DMS app, one can select Steering, after which there are four steering modes between 'Effort' and 'Response' to choose from, including Light/Casual, Standard/Standard, Standard/Quick, and Heavy/Quick. Basically, the settings determine the degree of resistance one feels when turning the steering wheel.With DAS, the vehicle has a tendency to wander, float, and swerve from side-to-side, which requires constant steering corrections. Unlike conventional steering, when negotiating a curve on a highway with DAS, you can't simply turn the wheel and hold it there as you progress through the curve. If you attempt to do so, you will quickly find that a few seconds after you turn the wheel slightly, the vehicle will stop going in the direction of the turn and will begin to go straight, so you have to keep turning the wheel back in the direction of the curve. This, in turn, results in the vehicle wandering from side to side. Additionally, with DAS, the vehicle tends to follow any uneven seams or other such things in the road surface. When passing or being passed by trucks (and even other cars), the wind drafts will blow the car to the side and require diligence with the steering wheel because one must anticipate and compensate for this. I cringe to think how it might perform when driving on the freeway with strong gusting winds and slippery road conditions. On the bright side, my experience thus far has been that DAS performs decidedly better when driving around town as well as on country roads. Quite frankly, I am utterly baffled as to how this steer-by-wire system ever made it into production. What in the world were they thinking? It remains to be seen whether or not there will eventually be a Technical Service Bulletin about this glaring problem, and if so, whether or not a firmware update will even be possible in order to fix the problem. When driving on highways with the Driver Assist on, the vehicle will wander/bounce back and forth within its lane if you let it, rather like a bobsled.In my experience, the vehicle tends to wander from side to side unless you're very diligent about keeping it on track. This has me worried that I might get pulled over by the police for driving as if I am intoxicated! However, I have found that the vehicle wanders the least in the Heavy/Quick setting. I suspect that the run-flat tires may be part of the problem, and I would be very curious to see how it performs when I eventually replace them with a set of Michelin Primacy tires. According to the internet, the majority of consumers don't like run-flats because they impart a rough ride, cost a third more than conventional tires, and wear very quickly. It's frustrating that the automotive industry is increasingly cramming these tires down our throats. I have read reports that BMW, for example, may void the warranty if these tires are replaced with conventionals. Fortunately, with the 2015 Q50, these tires can be replaced with conventional ones without voiding the warranty. Additionally, the vehicle has a spare tire that can be replaced with a conventional one.

I purchased a 2015 Q50 Premium just over two months ago with a little over 28,500 miles on the clock. The car was still under the original manufacturer warranty for another 11 months or up to 60,000 miles. Before purchasing, I took the car for a test drive and checked the carfax report, which showed that a previous Infiniti dealer had completed a CPO inspection at 28,038 miles and sold it as a CPO. Unfortunately, with less than 500 miles under my possession, the car experienced catalytic converter problems, but Infiniti took care of it. However, a week ago, the engine started hesitating and the low oil pressure light came on. I had to get the car on a flatbed and take it to the dealer, where I was informed that the car needs a new engine. Infiniti refused to cover the repairs required due to oil sludge inside the engine, claiming that the car was not properly serviced. The car has only done 28,768 miles. I am now in the process of finding all service records from the previous owner to go back to Infiniti and dispute their claims. I did find that many others had similar problems with sludge buildup in their Infinitis. Some of them were covered by warranty only after a lawyer got involved. So, if you are thinking of buying a used Infiniti, think again or at least demand all service records, even if the car has very few miles on it.

I chose the Q50 over the BMW because I could get a V-6 for the same price as the BMW 4-Cyl. turbo. While the acceleration is fun, the car does not grip the road like a BMW and the handling can be a bit squirrelly. Additionally, I have experienced a strange ping sound when backing out of a parking space with the Q50. Despite bringing it to the dealer 6 times, they have been unable to fix it, even after replacing the steering column. Another issue I have encountered is that the center console is too small for my iPhone 6+. Overall, my relationship with the Q50 is a bit of a love/hate one.

I've been the proud owner of this car for almost two years now. While the power is outstanding, I've noticed that the ride can be a little rough at times. However, the interior is nice and the BOSE sound system is outstanding. I find the seat comfort and room to be just fine, even at 6'1

The car looks great and has a strong engine. The interior is comfortable, especially on road trips. However, I have experienced some disappointment with the car overall and have buyer's remorse. Unfortunately, the inTouch electronics have been buggy, slow, or just plain don't work. The dealer has been really nice, but they can't change the poor quality and design of the manufacturer's electronics. I have a complaint logged with Infiniti Consumer Affairs, and they were also really nice, but unwilling to do anything about the problems I've had. I've had the car for about a year and a half, and it has been in the shop cumulatively for almost a month. After today, when several functions of the car electronics disappeared, I now have to schedule it into the shop again. This has been a frustrating experience, especially since I have never had problems like this with any car I've ever owned. This is my second Infiniti, but I'm not sure if I will purchase another one in the future.
