AIR BAGS,SEATS

Car throws a B1018 DTC, which is for the passenger seat occupancy sensor. The seat occupancy sensor failing poses a major safety risk, as it causes the airbags to not deploy properly in the event of a crash. This is a very well known issue for the 2011-2012 LEAF, and the only option Nissan gives to fix this is a full seat replacement, which is cost prohibitive at over $3000. Previously, a recall was issued for 2013-2016 LEAFs for a similar issue, but the 2011-2012 was not included in that recall.

AIR BAGS

Air bag sensor fault, passenger seat warning on dashboard. Confirmed sensor failure at repair shop. Notified by Nissan that sensors are DISCONTINUED parts. No alternative solution suggested. This means all airbags in this vehicle are disabled. Car has less than 40,000 miles and has years of service life left. How is Nissan allowed to discontinue supply of an essential safety component?

Please see thread: [XXX] My 2011 Nissan Leaf's OCS has failed randomly. I pulled the code via an Bluetooth OBD reader and the LeafSpy Pro app installed on my phone: B1018-00 09 AIR BAG Occupant Sens [Unit Fail] SRC-41. I took the car to a local dealership and was quoted over $4k for a full seat replacement with no ETA as the part is on back order. There is no option to simply replace the OCS alone and there is no workaround from Nissan to re-enable the passenger airbag without paying the $4k for the new seat. Opened a case with Nissan Consumer Affairs who advised they could do nothing for me. The repair is more expensive than the value of the vehicle. Because Nissan offers no workaround other than paying $4k for a new seat, consumers are incentivized to bypass the airbag sensor using a 3rd-party box (see here [XXX] rather than properly repair it. This is a safety issue and Nissan should do the right thing in making the repair affordable or making an official way to bypass the sensor/enable the airbags.

ELECTRICAL SYSTEM,SERVICE BRAKES

When applying brakes, at a point in the pedal travel the vehicle deceleration goes from too little to vastly too much. This makes the vehicle challenging to drive in traffic without colliding into the vehicle in front and not stopping so quickly as to cause the trailing vehicle to collide. The dealer has confirmed the behavior. There is a TSB to supposedly address the problem, and a receipt is attached of that TSB software update being applied. However, this has not changed the behavior. This is at least partially a software issue, since the vehicle blends physical brakes with EV regenerative braking.

Supplemental air bag warning light started blinking on 9/24/2023. It blinks regardless of whether the front passenger seat is occupied. The OCS sensor for the passenger seat failed. This should have been covered by a recall. The dealer wants over $3,000.00 to replace the seat cushion. I declined the repair. Dealer assured me that driver air bag isn't affected, so I'll operate the car without a front passenger. Dealer Estimate: Denied Repair Step Step Total: $3,687.14 Correction: inspected system, dtc b1018 for occupant sensor unit failure is present. Cleared dtc, when sitting in passenger seat, dtc came back on. Inspected continuity to passenger seat occupant sensor and found ok at this time. Diagnosis says replacement of passenger occupant sensor assembly (lower seat assembly) Labor: $588.00

VEHICLE SPEED CONTROL

Vehicle doesn't slow down when taking foot of the acceleration pedal. Same both power settings. It will continue to move at slow speed on level ground. It behaves as though the minimum pedal.motor speed is too fast. My concern.is that it might get very fast without any pedal. Thank you.

My airbag sensor light went off for no reason. I took it into the dealership and was told that it would cost $3,700 to get it repaired/replaced since the seat needs to be removed. I am concerned that this safety issue is not taken care of and have read that many 2011 Leaf's are having this same issue.

VEHICLE SPEED CONTROL

On 05/28/23 while i was trying to park my 2011 Nissan Leaf in a parking lot, the car accelerated unexpectedly and hit a pole and fence and scratched an already parked car. Applying break did not slow down my car. I own this car since 2011 and never had an experience like this.

AIR BAGS

The airbag warning light has come on. An independent shop and the dealer say the repair is $4500 or more -- greater than the value of the vehicle, because Nissan only sells the complete passenger seat as a repair part, and requires the airbag be paired with the car at the dealer. I ask that this situation be resolved by Nissan making just the seat cushion available as a repair part, as they have for recalls of airbags on other model year cars. The SAFETY problem is that Nissan's refusal to sell a repair part, leads to a FISCAL INCENTIVE TO BYPASS THE AIRBAG. See also NHTSA #: 08V-521

Air bag occupant sensor in front passenger seat failure causing air bag system shut off. DTC Code: B 1018 Description: Air Bag Occupant Sensor (Unit Fail). Well documented common failure of this critical safety component on the Nissan Leaf Forum. Sensor is not available to replace the defective part and a recall campaign was issued by Nissan, but doesn't cover 2011-2012 models. The vehicle is available for inspection upon request. The system scan revealed the DTC Code. Code returns after code clearing. Component has not been inspected by manufacturer. Air Bag Warning indicator lamp and Air Bag Off X 2 lamp illuminated.
