2011 Nissan Leaf Problems, complaints & recalls

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 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: [[redacted]] 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...

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...

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.

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.

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

Airbag light comes on when it should not. Vehicle disables the passenger airbag because it has code B1018. Airbag should not disable when an adult is sitting in the passenger seat. Code can be reset, but will come back any time someone sits in the passenger seat, regardless of size.

I recently purchased a 2011 nissan leaf vehicle from a private party. I quickly noticed that my battery capacity was at 5 bars and the vehicle has 73300 miles. I also noticed the ev system warning light was on. I took the car to my local nissan dealer and let them know that I was going to need a new battery but wanted to know the history of the vehicles battery because I believe that the degradation of the vehicles battery would fall into the severe category and because the vehicle was in between owners at the time...

Air bag light flashes indicating air bag system inoperative. It can be reset by recycling the car on/off 3 time within certain time limits. The light starts flashing again within about 5-20 miles of driving. Same problem on other nissan leafs that were previously recalled. 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 brakes malfunction at low speeds, but are not included in a recall program. Nissan has not helped and does not respond to emails or questions on twitter. At low speeds the brakes will sporadically engage and disengage with regenerative braking enabled. They will sometimes catch which causes sudden stopping or skidding in hazardous conditions. They will also not engage until they are pressed extremely hard which will also cause sudden braking and can be hazardous in traffic or hazardous conditions. I've been attempting to reach nissan to resolve the issue, but they do not respond. This is an ongoing issue that makes the vehicle dangerous to drive at times.

Passenger air bag has shut off. Dealer ran a diagnostic test and said I need a new passenger seat at a cost of $3,182. Current fault code is b1018.
