As with all other vehicles, if you follow regular maintenance schedules and take good care of your Infiniti G37, it can last you 200,000 miles and beyond.

Top Infiniti G37 Problems

As mentioned above, the probability of having to do major repairs on the G37 is quite low compared to other vehicle models. Despite this, there are still a few issues you need to be aware of before purchasing a used unit. Below are some of the most common Infiniti G37 problems:

A/C Blowing Warm Air

According to CarComplaints.com, one of the most serious 2013 Infiniti G37 problems is a faulty A/C system. The affected owner has reported that the A/C on their vehicle suddenly blew out hot air four years or around 113,000 miles after they had purchased the vehicle. They had their vehicle taken to a mechanic and they found out that the problem was due to a seized compressor.

But after a second check a couple of days later, the mechanic told the owner that a couple of pipes connecting the radiator had clogged up and the radiator had to be replaced. As of writing, there is only one report of this incident on the website. There have been no recalls or technical service bulletins (TSBs) issued yet to fix this issue.

Brake Pedal Vibration

An Infiniti G37 owner had reported that his vehicle would vibrate and that his wheel would shake whenever he applied the brakes firmly. The affected owner had assumed that the issue had been caused by a faulty rotor pad. This brake pad vibration issue only has a single report on CarComplaints.com so far. According to the same report, the owner had noticed this issue at around 26,000 miles. As with the A/C issue above, there have been no TSBs or recalls released to address this problem.

Airbag Sensor Malfunction

Airbag-related issues are a cause for concern because they can put the occupants of a vehicle in danger. Unfortunately, this is one of the major 2011 Infiniti G37 problems. The airbag sensor determines when to deactivate or activate the airbag/airbag light when someone sits in the seat. But many people in this Infiniti G37 owners forum have reported that the airbag light has illuminated at rather unusual times. According to the only report of this issue on the CarComplaints website, it took $6,700 for the affected owner to fix the issue by replacing the entire seat and sensor.

According to CarComplaints.com, there are no active recalls or TSBs for this issue. However, Infiniti does have an online resource where you can check if your vehicle has an active recall. As of writing, the only airbag-related recall on the Infiniti website is for vehicles equipped with Takata airbags.

Seat Not Working Properly

This issue had only one report on CarComplaints.com, but there’s a good reason why the website tagged this as the worst 2010 Infiniti G37 problem. According to the affected driver, the driver seat had reclined all the way back and would not return to its original position. To fix the issue, the seat bottom, rails, and all the controls had to be replaced. The affected owner said that he had experienced the problem at approximately 42,500 miles. It had also cost him $2,000 to fix, as the issue had happened after his warranty period had elapsed. As of writing, there are no TSBs or recalls issued to fix this problem.

Cracked/Melting Dashboard

The 2008/2009 Infiniti G37 problem with the most reports is a cracked dashboard. According to the affected owners, pieces of the dashboard had fallen off and needed to be glued back into place. Some owners were surprised that despite doing regular maintenance and having a dash cover, they still encountered the issue. Some even noticed that their dashboards had bubbled up and peeled at the corners. A 2008 Infiniti G37 owner had pointed out that what was happening looked like a chemical reaction. While there were calls for a class-action lawsuit for this issue, there are currently no lawsuits filed for this issue. In a forum for G37 owners, affected owners shared more cost-effective tips to fix their melting dashboard. One owner suggested getting a new dash for $150 at a junkyard.

When one G37 owner brought their vehicle to the shop, the mechanic told them that this had been a common issue in 2008-2009 Infiniti vehicles. On average, owners had noticed this issue at around 50,000-70,000 miles. All of the affected owners had to get their dashboards replaced, which cost them upwards of $2,000 to fix.

Overall, the Infiniti G37 is a good vehicle choice, especially if you want to experience the performance of a luxury midsize car for a more accessible price. Make sure to research first about the model year you want to buy and you’re all set. Just remember to clear everything up with the seller before you make your purchase.

    • After shutting off my car it beeps. like 2 or 3 times and then every 2 ish min...I have no idea what it is

      • I have a convertible. That happened to me and I found the only way to stop it is to recycle my convertible top. Open and close it. I also found that if I popped my trunk it would stop , but I too had trouble because the battery would drain.
        If your battery is removed from the car for any reason it somehow messes up your system. I think if you go on line and how to remedy this, you’ll probably get an answer. I found the G35 club and someone helped me! I know it’s a different model but most of the car is the same. Wish I could answer. I called the dealer and of course they wanted me to bring it in and charge me $350 to “reset “ my electrical system. Most things you can find answers
        to either from the cars manual or on line for free. Just gotta look a little bit more sometimes. good luck. Christie

  • I love the Infiniti G37 and the way it drives, but the dashboard has broken in about 30 pieces. It literally is falling into the floor. I took it to the dealership and they claimed that Infinity had never heard of this problem, and it was because the weather is too hot where I live! For that reason, I'll never buy another Infiniti.

    • you do know that they have dash covers and windshield sun shades . you should get one for all your cars if its t hat hot where you live.

  • I have owned 18 cars so far in life, with 5 of them being Infiniti G series coupes or sedans vehicles including 2003 G35 coupe, 2003 G35 sedan, 2007 G37 coupe models (along with a 2012 G37X coupe and 2019 Q60 coupe I currently possess).

    Is it Lexus? No. But they are good enough for the money, and don't come with that Lexus price tag. Overall they have been very reliable along with being inexpensive to maintain, as well as easy to repair. In fact the coupes and sedans have been become even more reliable over the ensuing years. Not to say this will be the case for every Infiniti model, for typically most car companies have at least 1 or 2 models a year which dont live up to advertised standards, and Infiniti is no exception. However there are companies out there (and you know who they are), whom to this day will sell you a new car with a high probability of an engine or transmission failure within the first 24-36 months.

    From personal experience, universally around 150 - 180K you need to look at replacing all control arms, shocks/struts. Also could need a software update from the dealer for the transmission for potential occasional rough downshift within the first 40K miles.
    Beware if you take it to a transmission shop they will ALWAYS tell you your transmission needs replacing. Something I have NEVER needed with these units.

    • Thank you for your nice post. I have a 2010 G37 convertible. I love that car. What a nice ride. It has some issues like I hate the seatbelt set up but had mine fixed. The battery’s don’t last long for some electrical reason I will never under but replacing a battery doesn’t bother me. Not for what I get to drive. I’m having my car’s Upolstry (just the drivers seat cushion redone on TJ and the hood repainted as well. Other than those minor costs, the car is penny. The different tire sizes , front and back kinda irritates me cause I buy tires more often than most I think, but again I love the car so it’s not a big deal. As far as the Lexus, the don’t make anything as sleek as this car. Just my opinion. And like you said, for the price ...... this car can’t be beat!

  • I own this car it’s a complete piece of junk.I have actually owned four Infiniti’s throughout the years. Up until till now I would always stand behind them but this car is an absolute complete piece of junk with more transmission issues than any other vehicle I’ve ever experienced in my life. After owning one an i30 15 years ago, it’s very apparent that infiniti is doing nothing but taking advantage of its customers.Building cheaper cars and selling them for higher prices.All good I can guarantee one last customer here I’ve owned four of them in my lifetime and I will never buy another one again. Don’t make the same mistake

    • So you had three cars that were amazing, and you swore by them. Then you got one with some issues. Now your conclusion is that all infinitis are terrible and they are taking advantage of their owners, despite you being a proud and happy owner of 3 Infiniti G's prior. None of this makes any sense. Cars break sometimes. Sounds like you got one bad one and are super salty about it. I'm personally on my third and the only thing I had to do with my 2nd was control arms, and first was starter/alternator, and all have made it over 200k kms. Just bought my 3rd one now, actually, and it's the best one by far in terms of condition. Maybe you're just very bad at selecting used vehicles.

  • I have a 2009 G37X that continuously have a parasitic draw, I've taken it to 2 different mechanics and gone through 3 batteries within two years. Has anyone out there experienced this issue before, if so did you resolve the issue?

  • Another problem worth mentioning for broad awareness is the galley / gallery gasket, which on early VQ37VHR engines tends to fail, reducing oil pressure to one or both timing control solenoids, leading to ping / knock / detonation / preignition (often audible when accelerating from a stop with engine at normal operating temperature, sometimes throwing a code or even invoking engine fail-safe mode). Significant labor is involved in replacing that inexpensive part (which Infiniti improved in ~2012), but ignoring this particular problem is rolling the dice with a truly impressive engine (especially when not refueling with premium unleaded)...
