Nissan dealer wants $250 and change to diagnose the problem and then tell me what the solution is, but everybody already knows the solution in a few thousand dollars to replace the passenger seat and sensor. The Nissan customer affairs office insists that I pay the diagnosis fee despite the fact that the dash board light already diagnoses this problem, which along with the know history of Nissan Leaf clearly points to the known problem. Nissan customer affairs says "we will consider good will assistance" - after I pay the diagnosis, but later in the call noted that the car is out of warranty so it is clear no good will assistance is being considered. The dealer service manager (hayward) tells me that he has had a number of Leafs in with the airbag light flashing and it could be "anything from a loose connector to the wiring harness, " which interestingly is a set of possibilities that excludes the sensor/seat replacement which is the well known fix. This is a safety issue that is Nissan's responsibility. Please recall this vehicle. Thanks.
The airbag warning light and danger symbol began flashing recently. Took the car to the dealership and they said the airbag sensor in the seat failed and needed to be replaced and the airbags would not function until the repair was completed.

The passenger seat occupancy sensor is failing. This causes the passenger airbag to turn off and the warning lights to flash on the dash. This condition may also disable the drivers airbag. Nissan estimate to repair is over $3200, the entire seat cushion assembly must be replaced. This is over half the value of the car. Nissan has recalled other years and models for the same or similar issue, but not the 2011 model. This serious, known safety defect should be addressed by Nissan in a responsible manner. The OCS system can be reset, but the trouble appears again in a few days. It usually appears on vehicle start-up. The passenger seat may be occupied, or not.
Passenger seat airbag sensor failed. Same issue as other complaintants. Vehicle stationary. This is the same issue as an existing recall for later year models. When is this recall going to be extended to earlier years? this is a safety issue and Nissan is trying to charge over $2K to fix.
The light for my sensor for my passenger airbag (OCS sensor) is on all the time and flashing red with or without a passenger in the passenger seat. Seems a big safety issue as I was told all air bags are disabled when the light is flashing. Cost involves replacing passenger seat too and total would be $4,800. This is a 2011 Nissan Leaf with 78,000 miles and all 12 bars of range still remaining (one replacement battery two years ago). I have not had it repaired due to cost and it is not part of a recall of the same problem in 2013+ Leafs. No 2011 recall for this safety problem!
While driving and making a right hand turn, the air bag light came on. Took it to the dealership. A check of the diagnostic codes showed that the passenger occupancy sensor failed. They reset the code and it cleared for 2 weeks, then re-appeared. Was informed that repairs to replace the passenger occupancy sensor was $2700 + labor. This same part was recalled in 2013+, but not recalled on 2011/2012. The repair is very expensive because Nissan will not sell just the airbag sensor--you must purchase an entire seat.
The light for my sensor for my passenger airbag (occupant classification system OCS sensor) is on all the time and flashing, even when there is an adult passenger sitting in the car. After a search online, I found that Nissan Leafs from 2013 to 2018 have been recalled for that OCS part, but my 2011 Nissan Leaf has not. Online, many other owners of my same year Nissan have had the same problem. My dealer told me, in order to replace the sensor, since it is outside the warranty, it will require replacing the entire passenger seat, which is upwards of $2700, not including labor. I called Nissan, who told me that it is too far out of the warranty, and they cannot help me. The customer service agent tried to get me a courtesy reimbursement, but he was unable to convince the higher-ups, and also couldn't even convince them to reimburse the amount I had to pay to have the dealer confirm what I already knew about the defective part (another $145). I am now forced to ride without airbags for my front passenger. It seems unconscionable for Nissan to allow a sensor (a part integral to the safety of the vehicle and not affected by normal wear and tear of the car) to not be part of a recall, especially when so many other vehicles (Nissan and otherwise) have the exact same issue. I can only assume it's because the sensor is too difficult to replace cheaply. They likely figured out the problem within the first few years of the car's manufacture and changed the location of the sensor - hence the reason they would agree to replace those in later models and not their earliest models.
Passenger airbag system disabled by occupant sensor failure. This happened on startup. Dtc B1018 air bag occupant sens [unit fail] I want model year 2011 Nissan Leaf to be added to the existing recall for models 2013 Nissan Leaf.
Occupant sensor failure is preventing the passenger air bag from deploying. The code is reported as a B1013. As this model was designed with a sensor within the seat, the official action is to replace the entire seat, for an estimate of $3133.51. This is highly cost prohibitive for a safety feature that should not prevent an air bag deployment.
