If you search the internet, you'll see that there's a large problem with the sunroof drainage in this car dumping water into the cabin, into the glove box and down the right kick panel, which is where the bcm unit sits, and then dumps down the rocker panel where all the electrical wiring runs.

What 2012 Infiniti G37 owners say
Most recent owner complaints, unedited.
I purchased this vehicle, 2012 Infiniti G 37XS in September 2023. The vehicle was basically brand new with less than 2200 miles on it and I have driven it very little up to that point, October 2024, as it is not my primary vehicle. Around [XXX], I believe it was around 8100 miles and change on the vehicle, a warning light came on my dash regarding my passenger airbag. Since that date, I have worked with Plaza Infiniti in Creve Coeur, who has looked at the vehicle a few times and identified that there is no part replacement other than OEM that can fix this issue. However, the part has been discontinued. Today, I reached out to Infiniti directly, and with a sad heart, they refuse to even listen to me. Now, I have a vehicle that has a safety issue and no way to fix it. The part number 87300–1NL6A, is the lower seat assembly for the passenger side of my 2012 Infiniti G 37XS. This part also has the occupant sensor which is directly affecting the airbag. The sensor is not replaceable separately of the lower seat assembly.

The contact owns a 2012 Infiniti G37. The contact stated that the air bag warning light was illuminated, and the message "Seat Belt Off" was displayed. The vehicle was taken to the dealer, where DTC code: B1018 was retrieved. The dealer determined that the passenger's side seat occupant classification system sensor and module diagnostic unit had failed and needed to be replaced. The vehicle was not repaired due to the cost. The dealer referred the contact to the federal safety agency Hotline for assistance. The manufacturer was not notified of the failure. The failure mileage was approximately 178,789.
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?
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 bag alert warning light and this 2012 infiniti g37 and it should be added to the recall list
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
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.
Sun roof drains are defective and are leaking puddles of water inside passenger & driver side of vehicle .
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.
