Infiniti G37 problems
The Infiniti G Line is a series of compact executive cars manufactured and marketed by Infiniti, a luxury division of Nissan, for the 1991–1996 and 1999–2016 model years — across four generations.
The first two generations of the Infiniti G (P10 and P11) were sedans based on the Nissan Primera. Beginning with its third generation (V35), the Infiniti G have been rebadged versions of the Nissan Skyline line of sedans and coupes that were exported to the United States and Canada. The fourth generation (V36) introduced the hardtop coupe convertible. The Nissan FM platform, used with the third and fourth generations (V35 and V36) of the Infiniti G, also underpins the Nissan 370Z and has shared components with the Infiniti M, Infiniti EX, and Infiniti FX.
Infiniti established a new naming convention beginning with the 2014 model year; all passenger cars are designated by the letter "Q," while sport-utility model names begin with "QX." The Infiniti G was to have been replaced by the Infiniti Q50, but the G37 was revived as the Q40 beginning with the 2015 model year.

Infiniti G37 2011
- Date Of Incident: 2017-09-27
- Date Complaint: 2024-09-27
- VIN: JN1CV6EL5BM
- Components: STRUCTURE
- Summary: The contact owns a 2011 Infiniti G37. The contact stated that the sunroof drain was leaking, causing water to enter the cabin of the vehicle. There was mold beginning to form in the cabin of the vehicle, with a noticeable mold odor inside the vehicle. The vehicle had been taken to a certified mechanic who diagnosed that the hose for the sunroof drain needed to be replaced. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The failure mileage was 89,000.
Infiniti G37 2009
- Date Of Incident: 2024-08-21
- Date Complaint: 2024-08-30
- VIN: JNKCV66E79M
- Components: AIR BAGS
- Summary: Light blinks for (no airbag on passenger side) working. Light also blinks on dashboard showing no airbags. My car has just over 76,000 miles with meticulous maintenance and no crashes, accidents or even bumps. There are countless complaints, inquiries and threads on the internet regarding the above mentioned problem. I don't know if anyone has taken the time to make an official inquiry but it requires your scrutiny. The fix is a new seat and or an old one that the components still work. There are countless people drivng this vehicle without airbags. We need a fix that won't cost $10,000 (estimate from dealership). Also, where can one find a seat??? Inifinity needs to provide a fix that allows the airbags to function properly without the consumer having to find a new/used seat (and none are available nationwide). The modules are a mere $200 but integrating them into a seat is impossible, so the "fix" is a new seat. This problem exists as the cars age. I project that all inifinities with this style seat have, or are going to have, the same problem as they age. If not, what remedy did Infinity offer in its newer models, leaving the rest of us driving death traps, with no means or opportunity for safely find a "fix". Attached is a copy of the scan from an auto body delearship regarding the lights.

- Summary: My vin # [XXX] comes up as a 2 door 2011 infiniti g37. Mine is a 4 door. The problem is the air bag light started to blink and the airbag light would show passenger airbag. I've researched enough about the takata air bag recall and the 2011 infiniti g37 is a part of that recall. It's mind boggling just thinking about the dangers of my vehicle that I need to get to and from work daily as well putting anyone on the passenger seat. I don't even feel safe driving the vehicle anymore. What can be done, its obvious it's not working properly. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Every time the dash gets in the sun and heat it gets worse. It causes a glare on the windshield that is blinding. I'm afraid the blind spots are going to cause me to hit a person or another car. I contacted Infiniti and they said there is nothing they can do since the car is out of warranty. What can Infiniti do to resolve this dangerous situation?

I was looking for a fun car in addition to my FX35. After test driving the Audi TT, BMW 335ix, and the 370Z, I found that the G37x offered the best value and comfort. I can always count on Infiniti for quality. My final decision was based on a combination of factors including performance, comfort/toys, fun to drive, value, and reliability.

I purchased this car from a lot as a stolen recovery with 52k miles and a salvage title, which allowed me to get it for a great price. Despite the initial concerns, the car has proven to be in great condition with no issues, except for a door seal that I had to replace. I absolutely love this car! It has more power than you'll ever need, and it can pass anything at any time while still getting 26-28mpg hwy and 22 around town. The handling is precise and crisp without being twitchy, and it handles curves on rails. The seats are very comfortable for long drives, and the interior is luxurious and quiet. Although there are a couple of minor issues, such as the cruise control not being very accurate going up and down hills and the transmission having a lag between off-throttle and back-on engagement, I have gotten used to them and they are no big deal to me now. The only other small thing missing is a headphone jack interface to play Pandora off my phone, but there are still plenty of music options available, including a USB connection in the console that works with my iPod and a hard drive to copy my CDs onto.Overall, I've owned a lot of cars in my many years, but this one really suits my style. It's aggressive when you want to be, comfortable when you don't, but always ready to rip, and just a joy to drive anytime!

After spending 17 months carefully reading reviews and test driving every car in the entry level luxury class, I finally chose the G37X coupe. I purchased the car this May, but I had the opportunity to test drive it during a Michigan snow storm, and I was impressed with its road grip and handling in both good and very poor road conditions. This car is truly superb in every way. Its exterior lines are eye-catching and its interior refinements are top-notch. I'm also pleasantly surprised by its fuel economy, as I'm averaging 21 MPG with mostly city driving. Not too shabby! Overall, I think this car is awesome.

I bought the 6MT version with the manual 6 speed, nav, prem, tech, all wheel steering. I'm so happy with everything about the car! The handling is unbelievable and the acceleration is fantastic. The Bose system is great and it's wonderful to be able to store CDs on a hard drive and not carry them in the car. Just a friendly reminder, don't buy this car and complain about the MPG.

Vehicle year: 2008
This car is truly impressive for a luxury vehicle. It offers a thrilling and enjoyable driving experience while still maintaining the sophisticated feel of a luxury car. I appreciate that with just the Premium Package, you can get all the features you want and still keep the price around $37K. There are only a few RWD luxury sport coupes available with a stick shift for under $50K, and this one is definitely the best value. I found it to be just as good as a BMW (I test drove both several times) but for about $10K less.
Are you having problems with your Infiniti G37?
Ernest Nader 2024-04-29
Vehicle year: 2008
I have experience with a 2002 BMW M3 SMG and a 2008 Audi A4 6-Speed (GIAC chipped), and I found the G37S to be slower than both, perhaps only slightly faster than my A4 (again GIAC chipped). Additionally, the steering did not feel as tight as it did in my previous cars. At 28k miles, I noticed a lot of abnormal wear on the plastics and leather. Unfortunately, the built quality inside the car is comparable to that of a Honda Civic. While I had hoped to like this car, I believe that the 335i (which is often compared to the G37S) is a better car overall.
Neil Mitchell 2024-04-24
Vehicle year: 2009
After purchasing my 2009 G37 Convertible, I noticed a persistent creaking sound coming from both sides of the rear portion of the hardtop. That night, I put the top down and up, and noticed that the trunk had opened afterward, so I closed it manually. The next morning, I approached my car in the garage to find the trunk opened again. Two days later, the engine refused to go past 10 mph and the Engine Light was on, so I was forced to bring it into the dealership. It has been over 30 days since then, and Infiniti has tried to solve the problem twice to no avail. Unfortunately, I still don't have my car. I'm curious if anyone else has had similar experiences with Infiniti? Thank you for your help.
