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.
NHTSA complaint #11691957 — an unverified report by a vehicle owner.
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.

I am the original owner of this 2009 G37 sedan with only 12K miles. This car has never been in an accident. It is perfectly maintained and sits in a garage 99% of the time. Last week the airbag light flashed on. The dealer said the error code was B1018 (Occupant Classification Sensor malfunction). The cost of the passenger seat cushion alone is $7,500. This problem was also found on the 2007 & 2008 G37 models and part of a NHTSA recall (#08V521000). I found this problem all over the internet and this NHTSA site for this model year G37. PLEASE INVESTIGATE THIS PROBLEM. Why isn't this part of the 2007/2008 recall when the sensor is bad in both instances?

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.

WHEN IT RAINS HEAVY WATER GETS INSIDE THE CAR ON BOTH THE DRIVERS SIDE AND PASSENGERS SIDE LEAVING THE FLOOR EXTREMELY WET. IT IS GETTING THE WIRES WET. MANY INFINITI OWNERS ARE EXPERIENCING THE SAME THING AND BELIEVE INIFINITI NEEDS TO MAKE A RECALL.
NHTSA complaint #11533859 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11522719 — an unverified report by a vehicle owner.
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.

Immediately when I started driving, the sensors on my dashboard started lighting up. First the air pressure sensor, then the Tire serve sensor, and finally the key sensor. My turn signals were malfunctioning. They would go on and off without me triggering them. Then every time I came to a stop and accelerated again, my car would jerk back. I eventually pulled over and my car wouldn’t even turn off. I had to put the key fob in the key slot to get the car to turn off. Then, the car would not start back up. I had to have the car towed to the Dealership. When I arrived at the Dealership, they told me that there were two other cars there having similar issues caused by rain water getting into the electrical. Here is the diagnosis they gave me: UPON INSPECTION AND SITTING IN VEHICLE CAN SMELL AND FEEL DAMPNESS FROM CARPET. FURTHER INSPECTION FOUND WATER FROM SUNROOF DRAIN TUBES LEAKING WATER INTO THE BODY CONTROL COMPUTER AND CAUSED ELECTRICAL SHORT CIRCUIT WITH INTELLIGENT KEY SYSTEM AND IGNITION SYSTEM. PERFORMED ELECTRICAL TEST AND TRACED SOURCE OF FAILURE TO THE BODY CONTROL UNIT. (THE BODY CONTROL MODULE CONTROLS KEYS, DOOR LOCKS, VEHICLE IGNITION START, AND TURN SIGNALS), AND VEHICLE LIGHTS). INSPECTION FOUND THERE IS A SHORT IN THE BODY CONTROL UNIT COMPUTER DUE TO WATER INTRUSION. REMOVED BODY CONTROL COMPUTER UNIT AND FOUND WATER INSIDE THE CONNECTOR PLUGS. BODY CONTROL MODULE COMPUTER SHORT CIRCUIT AND IS COMPROMISED. NEED TO REPLACE SUN ROOF DRAIN TUBES TO ELIMINATE WATER INTRUSION INTO THE CABIN AREA AND ALSO TO REPLACE BODY CONTROL UNIT COMPUTER. It’s highly unlikely that there would be 3 cars with similar issues at one dealership on any given day if this was NOT a manufacturers issue. Please help me get reimbursed and start a recall for this dangerous issue. Thank you

My vehicle fuel gauge reading recently started malfunctioning. It showed 1/8 tank and 40 miles left before I needed gas. The gas warning light came on. However within a minute, it showed 1/4 tank and 80 miles left before I ran out of gas. So I thought I was OK because I was on the freeway and I was getting better mileage, so I could travel further. I drove about 10 more miles and all of a sudden the warning light came on and said I only had about 2 miles of gas left. My car started sputtering and I ran out of gas on the freeway. I was VERY lucky I was able to coast (no power) onto the emergency shoulder. I called AAA to bring me gas. I felt very unsafe being on the side of the freeway in Los Angeles, cars were passing me at 70+ mph, and several cars swerved to avoid me, even with my emergency blinkers on. I thought it might have been a glitch that only happened once, so I have been very careful about filling my gas well before I think it needs it. But then it happened again the other day. My gauge showed 1/4 tank with about 75 miles left but then a few minutes later it showed 1/2 tank with around 150 miles left. I stopped for gas and it took nearly 15 gallons (it only holds 17 gallons). This is extremely dangerous, and many other G35/G37 owners have this problem. (I have seen the exact same issues with fuel gauge readings in Infiniti G37 forums). My cluster is working (I ran the cluster diagnostic and all gauges are functioning) so I believe it must be either the fuel sensor, the float arm or possibly an AC Amp (a part that controls all the information sent to the gauge cluster, found near the radio?) I also saw that Nissan/Infiniti had a recall almost identical to this. Recall 10V074000. THIS COULD CAUSE THE VEHICLE TO RUN OUT OF GAS AND STALL ON THE HIGHWAY, WHICH COULD CAUSE A CRASH. Please advise if this can be investigated as a potential safety hazard and recall for my vehicle. Thank you!
NHTSA complaint #11503845 — an unverified report by a vehicle owner.
Sunroof drain failure causing rain water from the outside of the vehicle to enter the interior flooding the passenger side going from the front seats to the back seats. Due to the sunroof drain defect, the flooding of the interior causes the water to get into the body control module impacting the electronics which can result in numerous failures in the vehicle making it dangerous to drive. There are numerous videos on YouTube and posts on online forums describing this very issue which is extremely common with the G37. Infiniti dealer confirms the issue, but takes absolutely no responsibility. The cost of the repairs to the sunroof drain and body control module are completely placed on the consumer.

I was driving at about 65 mph on the tail end of a roughly 2 hour trip. The car shut off on me completely. Fortunately there weren't many cars on the road, so I was able to force the steering wheel - since power steering went out as well, I needed to turn the wheel forcefully - to the shoulder. The brakes worked ok, but not well, again because the engine shut off, so I was forcing the brakes and they took a lot longer to work than normally. Had there been normal to heavy traffic, I'd definitely have been in a very bad crash. The vehicle is available for inspection if needed. This is the second time this situation has occurred to me in this vehicle. There was no warning lamp, message, or symptom prior to or after the incident. A dealer, manufacturer, police, insurance, nor anyone else has inspected or reproduced the problem. Various Infiniti online forums reference the same issue.

The airbag control module can be damaged through normal use. Simply disconnecting the battery can damage the module, which then causes the airbag malfunction light on the instrument cluster to turn on. It is unclear weather or not the airbag will function when this occurs. Presumably, it will not. The dealer solution for this is to replace the module, at a cost of over $1000. Fortunately, it is possible to remove the module and send it to a 3rd party who can reflash a chip. However, doing this every time a random electrical glitch (common ) causes the warning system to trip is dangerous.

I have an electrical dash board that controls my speedometer, gas milage and all the major checks lights that is NOT WORKING. This is the second time I have had this problem and when you research the problem on the internet or YouTube, the infinity owners are saying its a major problem with the car and the computer system. Why hasn't infinity recalled this problem?

Rear speaker AMP caught fire and burned the rear of the vehicle near the fuel tankMarch 19, 2021. The electrical fire occurred several hours after the vehicle had been parked under an apartment housing complex carport. Had it not been noticed the structure along with several other vehicles could have caught fire. Pasco Washington Fire identified the source as the factory AMP in the rear of the vehicle having started the fire. It is available for inspection

REGARDING TRACKING NUMBER 11400119.- INFINITY CALLED ME TODAY(FROM PHONE NUMBER 6157257000. SHE SAID THEY ARE NOT INTERESTED IN MY CASE BECAUSE THE CAR HAS NO RECALL ON IT. I'M CONFUSED BECAUSE I THOUGHT YOU AND INFINITY WOULD WANT TO KNOW WHAT CAUSED THE FIRE AND IF OTHERS WITH THIS MODEL OF.CAR WERE IN DANGER OF BEING SET ON FIRE.

NHTSA complaint #11388798 — an unverified report by a vehicle owner.
THE PASSENGER AIRBAG LIGHT IS BLINKING DUE TO A FAULTY SENSOR CONTAINED IN THE PASSENGER SEAT. IF THIS LIGHT DOES NOT TURN OFF, NO AIRBAGS WILL DEPLOY IN THE EVENT OF AN ACCIDENT, WHICH IS A HUGE SAFETY ISSUE. INFINITI CHARGES MORE THAN $7000 TO REPLACE THE SENSOR AND THE SEAT TO FIX THIS OUT OF WARRANTY. INFINITI REFUSES TO DO A RECALL FOR THIS ISSUE WHICH HAS BEEN FOUND TO BE VERY COMMON IN NISSAN AND INFINITI VEHICLES.
