2012 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 The Infiniti G was to have been replaced by the Infiniti Q50, but the G37 was revived as the Q40 beginning with the 2015 model year.

Common 2012 Infiniti G37 problems
Common Problems with the Infiniti G37 2012
- Sunroof Drain Leak
The sunroof drain leak is a common problem in the Infiniti G37 2012, where water enters the car through the sunroof drains and causes damage to the car's interior. The problem can be solved by washing out the sunroof drain with soapy warm water and forcing air compressed air through the lines to blow out the debris. Some owners have had to scrap the A-pillar, sides, and glove box to clean out the line and fix the connector going to the firewall. If not fixed, it can lead to mold issues and big puddles in the car.
- Electronic Steering Wheel Lock
The electronic steering wheel lock is another common problem in the Infiniti G37 2012, where the steering wheel lock fails or is disabled. The problem can be solved by cleaning the contacts of the wiper and testing the resistance with a multimeter. If the contacts are dirty, cleaning them can fix the problem.
- Engine Control Module (ECM) and Body Control Module (BCM)
The ECM and BCM are essential components of the Infiniti G37 2012, and when they fail, the car may not start. One owner reported that water residue was found on the BCM, and when replaced, the new BCM did not communicate with the car's system. The problem was solved by using the old BCM and programming the key to it.
- Oil Gallery Gaskets
The oil gallery gaskets are a common problem in the Infiniti G37 2012, where the gaskets wear out and cause oil leaks. The problem can be solved by replacing the gaskets with new ones, but it is recommended to use the 2012 and above models to avoid this issue.
- Rear Radiator Hoses
The rear radiator hoses are a common problem in the Infiniti G37 2012, where the plastic coupling that connects the hoses cracks and causes coolant to leak. The problem can be solved by removing the intake manifold, flushing the coolant, and installing a bleeder valve.
- Spark Plugs
The spark plugs are a common problem in the Infiniti G37 2012, where they wear out and cause the car to misfire. The problem can be solved by replacing the spark plugs with new ones, but it is recommended to do so every 80,000 miles.
- Differential Fluid
The differential fluid is a common problem in the Infiniti G37 2012, where the fluid wears out and causes the differential to fail. The problem can be solved by replacing the differential fluid with new ones every 30,000 to 50,000 miles.
- Wheel Bearings
The wheel bearings are a common problem in the Infiniti G37 2012, where they wear out and cause the wheels to vibrate. The problem can be solved by replacing the wheel bearings with new ones.
- Transmission
The transmission is a common problem in the Infiniti G37 2012, where the transmission fails and causes the car to shift roughly. The problem can be solved by replacing the transmission with a new one.
- Brake System
The brake system is a common problem in the Infiniti G37 2012, where the brake pads and rotors wear out and cause the brakes to fail. The problem can be solved by replacing the brake pads and rotors with new ones every 30,000 to 50,000 miles.
In conclusion, the Infiniti G37 2012 is a reliable car, but like any other car, it has its common problems. It is essential to maintain the car regularly and address any issues promptly to avoid further damage.
What is the main problem with INFINITI G37?
With an annual repair cost of $540, the Infiniti G37 has lower maintenance fees than most luxury midsize cars. Some top Infiniti G37 problems include a faulty A/C system, a vibrating brake pedal, and malfunctioning air bag sensors.
How reliable is a 2012 G37?
Performance and Handling: The G37 is known for its strong performance and good handling, making it an enjoyable car to drive. Reliability: These models are generally considered reliable. However, as with any used car, the specific vehicle's history and maintenance will significantly impact its reliability.
Does INFINITI G37 have transmission problems?
If you don't routinely and consistently change your fluids at least every 30,000 miles or so, you may find that your INFINITI G37 transmission will swiftly slip. Check your car's owner's manual for more advice on the specific mileage intervals in which your transmission needs the fluid changed.
Is INFINITI G37 a reliable car?
I've had an '09 G37x and now a '13 G37xS, and can verify with my other pro mechanics that the G37 is one of the most reliable autos ever produced anywhere by anybody. Even brake rotors last longer than expected! On the negative side the twin exhaust will get a bit laborious to deal with after a bunch of salty winters.

UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2024-02-14
- VIN: JN1CV6AP8CM
- Components: UNKNOWN OR OTHER
- Summary: I just purchased a 2012 Infiniti G37 and love the car. Once I drove off the car lot I noticed the dashboard was extremely sticky and shiny and appears to be melting. 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?
UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2024-03-03
- VIN: JN1CV6AR2CM
- Components: UNKNOWN OR OTHER
- Summary: This car odometer is rolled back about 100,000 miles and I hope I am reporting this at the right place. I went to purchase this vehicle and seller paperwork doesn’t match up with vehicle.
AIR BAGS PROBLEM
- Date Of Incident: 2024-02-04
- VIN: JN1CV6AR6CM
- Components: AIR BAGS
- Summary: Air bag alert warning light and this 2012 infiniti g37 and it should be added to the recall list
UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2024-01-08
- VIN: JN1CV6AP6CM
- Components: UNKNOWN OR OTHER
- Summary: Sunroof drains get clogged and have to repeatedly cleaned out by dealer causing a LOT of water damage and possibly damage to the body control module
ELECTRICAL SYSTEM,AIR BAGS,SEATS PROBLEM
- Date Of Incident: 2023-05-10
- VIN: JN1CV6AP0CM
- Components: ELECTRICAL SYSTEM,AIR BAGS,SEATS
- Summary: I’ve owned this 2012 g37 for a few years and had no issues whatsoever. However within the last couple of months, my air bag light came on and has been flashing since. I’ve taken it to get inspected and had the system checked and was told my passenger seat occupant sensor malfunctioned and is throwing the code on. The sensor itself, very easily replaced, is unable to be bought by itself. Repairs by the dealership is well over 5,000 for the seat and labor. The sensor is being sold as a component part of the bottom build of the seat, and cannot be sold otherwise. The issue with the sensor not being active, prevents the activation of the passenger airbag regardless of the seat being occupied or not. My concerns are that I won’t be able to safely commute with passengers on the road and also being able to pass state inspection, as needed per law per state. Without this sensor, driving is an everyday peril, a safety concern a driver has no control over with other vehicles on the road. There has not been any prior incidents that have occurred that could cause this electronic issue.
UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2023-07-18
- VIN: JN1CV6APXCM
- Components: UNKNOWN OR OTHER
- Summary: Sun roof drains are defective and are leaking puddles of water inside passenger & driver side of vehicle .
AIR BAGS,STRUCTURE,SEATS PROBLEM
- Date Of Incident: 2023-06-20
- VIN: JN1CV6EK2CM
- Components: AIR BAGS,STRUCTURE,SEATS
- Summary: Passenger Side Air Bag sensor flashes possibility due to faulty sensor in passenger seat. Water enters cabin on passenger side causing water to pool on floorboards, possibly causing electrical damage and failure. Water entering could be due to flawed design in water channel or sunroof.
ELECTRICAL SYSTEM,UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2023-02-01
- VIN: JN1CV6AP7CM
- Components: ELECTRICAL SYSTEM,UNKNOWN OR OTHER
- Summary: There is a leak on the driver side down the front A-pillar. Water runs over the electrical components, fuse box, BCM. I’ve researched on the internet and this is an extremely common problem. If this component gets wet, the car could shut off while driving. Maybe there is a danger with being electrocuted as well. This is a design flaw and potential safety issue in the 2012 Infiniti G37, and it’s happening fairly often as seen with similar issues from other owners. Do I have to worry about this with my two kids in the car? Why hasn’t this been addressed by the manufacturer with the commonality of the problem? I had a similar issue on the passenger side. However, I was not worried about safety as the electrical components are not on that side. There is not the same risk for electrocution or car stoppage while driving. Nonetheless, it is still an extremely common problem and failure of engineering on the manufacturers part. Now I am dealing with the same issue on the drivers side where the electrical components come into play.
ENGINE PROBLEM
- Date Of Incident: 2022-06-30
- Fire: 1
- VIN: JN1CV6AR9CM
- Components: ENGINE
- Summary: The contact owns a 2012 Infiniti G37. The contact stated while starting the vehicle, the vehicle burst into flames in the front area of the vehicle. As a result, the front of the vehicle was severely burned and two parked vehicles nearby were damaged due to the fire. The fire department was able to extinguish the fire on all the vehicles. The contact did not suffer any injuries. A police report was filed. The vehicle was not diagnosed. The manufacturer was not notified of the failure. The failure mileage was unknown.
AIR BAGS,SEATS PROBLEM
- Date Of Incident: 2020-07-06
- VIN: JN1CV6FE5CM
- Components: AIR BAGS,SEATS
- Summary: The air bag sensor on the passenger seat has failed and the passenger seat does not recognize even an adult person sitting on it. As a result the airbag-off light for the passenger is always on and I am afraid if the rest of the airbags are working properly due to this faulty sensor. I looked up online after my sensor failed and it seems like this is a common issue for G37 vehicles. The only option to fix the problem is to replace the entire seat at a cost of anywhere from $6,500 to $8,500. My wife is afraid to ride in the car with me for fear the airbag will not deploy. There was no warning prior to the light flashing on the dash.
AIR BAGS PROBLEM
- Date Of Incident: 2022-08-15
- VIN: JN1CV6EK1CM
- Components: AIR BAGS
- Summary: I first noticed this problem on August 15, 2022. The front Passenger Airbag Off Light on the dashboard is always illuminated when the car is started, with or without any occupant on the seat, which would indicate that the airbag in non-operational and will not deploy when needed. At the same time, the Supplemental Air Bag Warning Light in the instrument panel is flashing. I have not brought my car to the dealer or any repair shop for inspection or repair. I just noticed similar complaints from other people in the internet for the same model year car and that the repair cost being qouted to them is upwards of $6000.00. I am also aware of an on going recall of other Infiniti models for a faulty Occupant Classification Sensor.
AIR BAGS PROBLEM
- Date Of Incident: 2021-09-15
- VIN: JN1CV6FE9CM
- Components: AIR BAGS
- Summary: My air bag sensor on the dash came on, so I took it to the dealer. The dealer told me that my air bag sense is not working and that I would have to replace the entire seat for 9,000 dollars to fix. My car is a 2012 and is worth ~ 12,000 dollars. So obviously I cannot not have them replace seat. I started researching if there was an alternative fix and found this is a very common issue with Nissan and Infinity on numerous makes and models, there are hundreds of posts where this is happening to owners of infinity and Nissan….so why has this not been recalled as a safety issue? I can no longer have a passenger in my car. But my guess is there are lives being put at risk daily due to the sensor failure. This is extremely disappointing that this is how Nissan and Infinity support the customers, our lives are at risk. Please consider looking into this as a safety recall for the hundreds of us that cannot invest in a 9,000 dollar seat to protect our lives.
VISIBILITY PROBLEM
- Date Of Incident: 2020-11-01
- VIN: JN1CV6AR4CM
- Components: VISIBILITY
- Summary: The contact owns a 2012 Infiniti G37. The contact stated that puddles of water were present on both the front passenger’s and driver’s side floorboard due to condensation and moisture from rainwater entering the vehicle. The contact was concerned that moisture would create mold and an electrical shock hazard inside the vehicle. The vehicle was taken to the local dealer who diagnosed that the sunroof drainage system was clogged and needed to either be cleaned or replaced. The failure was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 130,000.
TIRES PROBLEM
- Date Of Incident: 2021-10-12
- VIN: Jn1cv6ar6cm
- Components: TIRES
- Summary: Hello I am not happy with the tires the discount tire salesman keep selling me. The first time I bought Road hugger tires they looked like the picture that I attached. Then the sales man put me 2 front Road Huggers tires again in February 2021. Now my dealership is telling me last week .FRONT TIRES ARE WORN EXCESSILY ON THE INSIDE EDGES AND RUBBER IS STARTING TO PEEL OF TIRE. I don't have money to keep replacing.

- Date Of Incident: 2021-06-06
- Crash: 1
- VIN: JN1CV6AR2CM
- Components: UNKNOWN OR OTHER,BACK OVER PREVENTION
- Summary: On June 4 I pulled into a drive to turn the car around and park. I stopped the car, put it into reverse, and pressed the gas pedal;. The car stalled and I pressed the gas pedal again with the regular force. Suddenly the car accelerated and I felt a jerk and heard a bang as it hit a car that was just backing out of the driveway cross from min. My car was going so quickly that the other driver commented on the speed it was going. My car incurred considerable damage, the rebar was damaged, and I took the car int "collision" for repair. At Collision, I was told by 2 people that Mini had a problem with acceleration. Priori to the accident, my car occasionally stalled when I was backing it out of the garage. I have since been told that this "stalling" or "stumbling" was a signal that there was a defect that could have been fixed.

- VIN: JN1CV6AR0CM
- Components: AIR BAGS
- Summary: THE AIR BAG SENSOR ON THE PASSENGER SEAT HAS FAILED AND THE PASSENGER SEAT DOES NOT RECOGNIZE EVEN AN ADULT PERSON SITTING ON IT. AS A RESULT THE AIRBAG-OFF LIGHT FOR THE PASSENGER IS ALWAYS ON AND I AM AFRAID IF THE REST OF THE AIRBAGS ARE WORKING PROPERLY DUE TO THIS FAULTY SENSOR. I LOOKED UP ONLINE AFTER MY SENSOR FAILED AND IT SEEMS LIKE THIS IS A COMMON ISSUE FOR G37 VEHICLES. NISSAN SEEMS TO HAVE ALEADY HAD A RECALL FOR FAULTY AIRBAG SENSORS FOR MODEL YEAR 2007-2008 BUT IT LOOKS LIKE THE ISSUE HASN'T BEEN COMPLETELY RESOLVED IN VEHICLES FROM SUBSEQUENT MODEL YEARS TOO.
ENGINE,VISIBILITY/WIPER PROBLEM
- Date Of Incident: 2021-01-08
- VIN: JN1CV6APXCM
- Components: ENGINE,VISIBILITY/WIPER
- Summary: THE COOLING SYSTEM IN THIS VEHICLE HAS A TWO PART PERFORMED HOSE THAT CONNECTS THE ENGINE COOLING SYSTEM TO THE CABIN HEAT EXCHANGER. THE TWO PARTS ARE CONNECTED WITH A PLASTIC JUNCTION WITH TWO SPRING CLAMPS. THIS VEHICLE HAS APPROX 85K MILES AND STILL HAS THE ORIGINAL COOLANT. THIS JUNCTION DISINTEGRATED. IT APPEARS TO NOT BE COMPATIBLE WITH THE COOLANT. IT DELAMINATED AND SHEARED. LUCKILY IT BROKE WHILE STOPPED IN THE GARAGE. IF IT HAD HAPPENED AT HIGH SPEED IT WOULD HAVE SPEWED THE COOLANT AT THE REAR OF THE ENGINE, AND AT LEAST SOME OF IT WOULD HAVE GONE TO THE WINDSHIELD, OBSTRUCTING THE VIEW. I HAVE SAVED THE DISINTEGRATED PART.*DT*JB

QUOTED COST OF REPAIR AT $7200 TO REPLACE SEAT BASE. THIS IS OBVIOUSLY A DESIGN DEFECT WHEN CANNOT REPLACE A SENSOR WITHOUT REPLACING THE WHOLE BASE. THIS IS OBVIOUSLY A SENSOR DEFECT WHEN YOU SEE THE NUMBERS THAT HAVE REPORTED THIS FAILURE (IMAGINE THE NUMBER THAT DID NOT REPORT) THIS SHOULD BE A SAFETY RECALL AND. COVERED BY INFINITY. $7200 TO REPAIR A FAILED SENSOR IS UNREASONABLE.
