This vehicle has been in our ownership since July 2011, making us the second owner. Currently there is approximately 92,219 miles on the car. The airbag light began blinking without any incident or accident. We took it to the local dealership this week. We were told the occupant sensor failure code B1018 was the issue. Per their words on our invoice "cannot get sensor from Infiniti. Will need seat bottom to correct the issue." The estimated price for this repair is $6,400. I noticed the same problem was reported in the 2007 and 2008 models, and these models were recalled. So now I have no airbag protection which makes this a safety issue. I have spoke with Infiniti corporate office regarding this issue without any assistance in resolving the problem. In my opinion this is a manufacturing defect just as it was in the 2007 and 2008 models, and should be recalled.

Single owner G37 sedan diagnosed with error code B1018 after reporting a flashing passenger air bag light that suddenly came on. Service provider unbolted seat, disconnected occupant sensor component, cleaned all connections, reconnected and secured so that connector couldn't move. Tried to erase code but unable to do do. Was told I would need a new bottom seat cushion and frame at a cost of approx $3-4k (not including labor). Advised to look at NHSTA for recall information for myself as technician indicated there is no recall for my vehicle. My prior car was a G37 sedan which did have a recall for the exact same issue and it's illogical that this one does not. In reviewing this site, more than 50% of the complaints for this vehicle are tied to the air bags and I stopped reading other complaints when the first five I read all had the exact same issue. Namely, that the light came on suddenly without cause and the only way to correct it, was to replace the seat and sensor. Personally, there is rarely a passenger in my car and the only logical conclusion is that this part is faulty and the original G37 issue was not corrected. Subjecting consumers to the significant repair expense and more importantly, the inherent safety issue a faulty air bag can create, the manufacturer ought to bear the responsibility to correct.

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.

My dad gifted his 2009 infinity G37, which he purchased new, to my daughter. it has ~50,000 miles. One week into driving the car the air bag sign started flashing. Diagnosis indicated a B1018 error. Infinity of Escondido confirmed a failed OCS sensor for front passenger seat. Replacement cost: part $4100 bottom cushion with frame + $650 labor. Since the car has been hardly driven since originally purchased by my dad, it is clearly a case of a defective sensor, also considering that infinity G37 2007 & 2008 model years have been recalled for the same issue (recall # 08V521000). The entire airbag system in the car has been disabled due to this faulty sensor - this should fall under federal safety mandate and Infinity is refusing to assist. Called their consumer affairs department with case elevated to regional manager (case # [XXX]) making a request to at least meet me halfway through cost of parts - Their answer is sorry "NO". such complaints are prevalent across the internet with stories similar to mine and Infinity is not taking responsibility. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

On my 2009 Infiniti g37, the supplemental airbag warning light keeps flashing. I was told by the dealer that the problem is the sensors in the seat cushion and the cost of fixing it is $7,050.00. I asked if that was a common problem and they said yes. This light just start flashing one day without any apparent cause. My issue is that there should be a recall on this since this affects so many of the Infiniti g series. This is a problem that so many owners face and it is not caused by wear and tear or accident or any disturbance whatsoever. In my case, my right front seat is seldom used. I searched the internet and visited the infiniti forums and well as facebook and other platforms and the number of infiniti owners with this woe are many. I honestly think this happens due to some manufacturers defect and if there is an accident, the appropriate airbags may not deploy so this is a potentially dangerous situation. Infiniti needs to issue a recall for this item.

A recall was issued for a faulty passenger side airbag sensor on the Infinity G37 model year 2007 -2008 (08V521000). I own a 2009 G37 and it would appear this car is experiencing the same safety issue. The airbag off light for the front passenger seat remains illuminated even with a 200 pound adult seated in it. I also have a constantly flashing airbag warning that is displayed on the dashboard. I am extremely concerned that should my vehicle be involved in a crash, passenger side airbag will not deploy even though there is someone seated in that seat. Infiniti has stated that to repair this issue will cost over $5000 which is nearly the entire value of the car. This recall should be extended to additional model years of the G37.

Car got a flashing airbag light after battery replacement. Reset multiple times just for light to come back. Took to Mears Nissan dealership for diagnosis. Diagnosed with bad occupant detection sensor. Dealership quoted me $4,500 for part without labor. Perfectly good car no longer has operating airbags, my personal safety is now at risk because the cost of repair is greater than the cars value, and the part is on back order for an extended unknown period of time. Vehicle is available for inspection. No other lights at time of incident.
