When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2011 Infiniti G37
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

STRUCTURE:BODY
The sunroof’s drain ports clogging up is a known common issue to Infiniti dealers, as I have learned while taking my car in after the entire dashboard & electronics shorted out. The mechanic told me this is a common occurrence during the rainy season. Water may intrude the body through the clogged ports and the first location the water goes, happens to be the lower passenger side which ALSO happens to be the location of the body control module (BCM). The car has stopped operating on me in the middle of driving, and also wouldn’t allow me to get out of the gear I was in. What could be a $50 - $150 repair turns into a $2500 - $2800 repair.

POWER TRAIN
Hydraulic clutch fluid overheating causing catastrophic clutch piston failure resulting in not being able to engage, shift, or most importantly disengage the current drive gear in motion. The safety condition of not being able to disengage the operation of the vehicle puts the occupants at risk by limiting the ability to prevent collision. I have experienced this failure approximately every 20,000 miles, leaving the vehicle stranded on the highway with each occurrence of the event.

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)

Airbag warning light came on. Took the car to the dealer and they gave me an estimate of $10,858.62 to repair the airbag! I feel that this is a defect and should be a recall item as I have since read several complaints of the same exact problem! This car has been kept in the garage and only driven when the weather is beautiful! it only has 29,100 miles on it. We bought it from the Infinity dealer in Annapolis, MD in 2012.

I have been having issues with my passenger airbag warning light. The issue is warning light will not go out. I took my vehicle to an Infiniti dealer for a diagnostic. Dealer found code DTC B1018 OCS unit failure. Much to my disbelief and, dealer recommends new passenger side air bag diagnoses module and lower seat frame before further diagnosis. What really angered me was the price to repair a safety issue on this vehicle that wasn't caused by an accident or repair . The quoted module price was $1275.00, price for lower seat frame is $7695.00. Note, this is the price for parts and didn't include labor. At that point, I didn't ask what the labor cost was because I was flabbergasted and taken aback by the the excessively high price for repair. After reading 100's of forums, many are having the same issue with their Infinities and other Nissan Vehicles. Infinity and NHTSA must be aware of this massive problem and Infiniti/Nissan needs to correct this flaw in engineering at the companies expense. We as consumers who pay a lot for these vehicles should be protected. My concern is I have lupus and Arthritis and have chronic pain daily and need my car for numerous doctors visits. Since my health diagnosis I haven't been able to work the past seven years and can't afford to pay over $ 9000.00 to fix a otherwise good running vehicle but also can't afford to get into a car accident because the airbag will not deploy. Since I do have an illness, a car accident without a working airbag system my injuries or worst would be exacerbated by this Infiniti/Nissan flaw in engineering. Please advise as I need assistance with getting my car repaired.

Sunroof drain has malfunctioned multiple times, even after having the Infiniti dealer replace with brand new ones. This was a very expensive repair and has already failed again. Upon searching the internet, this is a known, common problem and Infiniti should have recalled this issue. Water has leaked into my car onto my electronics. Luckily, nothing major has occurred while I was driving like it has for other owners of this same vehicle, but my power functions are malfunctioning because of this flawed component. The vehicle has been inspected and repaired by an Infiniti dealer, who also told me that this is a very common issue with this vehicle and sometimes causes the car to shut off while it is being driven. There are no warnings for this issue - just a bunch of water leaking straight into the car and underneath the floorboard, where many electrical components are housed.

The occupant sensor in the front passenger seat has failed, rendering the Supplemental Restraint System (airbag) compromised and partially nonfunctional. Upon inspection, dealer states that they cannot ensure that entire SRS will function properly unless repaired. The proposed solution is to replace the Occupant Sensor Unit at a cost of $4,905. The SRS indicator light remains on as I have not agreed with Infiniti Dealer's proposed costly replacement. This puts the driver and any/all occupants at risk. There is a reasonable amount of internet discussion concerning this problem/safety issue with Infiniti.

I just bought this vehicle from carmax mid May 2022 and a little over 1 month now the car completely died. I drove it the prior day came home parked it in my driveway as aways and the next day when I had to go to work I was not able to unlock car doors with the fob key. I then proceeded to trying to unlock the car door with the option on the door handle and that did not work either. At that point I was already irritated and had to call work to let them know my current situation. I then tried the manual option key to open the door which worked but everything was dead. No lights no noise no clicking from the engine when push to start just dead. I assumed that I was sold a vehicle with a bad battery which already has me questioning carmaxs point inspection before selling a vehicle. This is already causing such an inconvenience on me but I need my vehicle for work so I then call my car insurance due to having roadside assistance and let them know I need a jump start because I’m really hopping that’s what it is. When roadside assistance arrives they set up the cables and then I’m told to start my vehicle. OMG. It did not start. At that point I was now feeling mad, taking advantage of, annoyed. Why am I going through something like this when I just bought the car over 1 month ago. Yes I know it’s a pre owned vehicle but having 62k miles you’d think you’d avoid these situations since they are always saying low mileage is better and it was still priced tagged at 23K at carmax and with financing well you get the picture. The roadside gentleman tells me that this car has seems to have something major that caused it to just die. I’m just like WOW. This is ridiculous. Now I have a complete dead vehicle that needs to be towed and I guess I have to contact carmax to let them know. This has been a nightmare and so extremely inconvenient on me and I might as well just mentioned that I also had the worst experience in my life buying this vehicle with carmax. I feel played.
