2011 Nissan Leaf Problems

What owners report

Owners of the 2011 Leaf most often report a failed passenger-seat occupant sensor that disables the passenger airbag and leaves a flashing airbag warning light, and they describe brake behavior at low speeds that feels grabby or inconsistent. Many complaints also describe battery capacity and range loss beyond what owners expected, and several mention power loss or electrical faults while driving.

   Electrical system

   Traction battery capacity and range loss

   • 20 complaints (21%)
   • median 21,094 mi at 2.2 yrs old (20 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2012–2020

   Owners report losing capacity bars quickly, sometimes within the first year, and a driving range well short of what the range display shows. Several describe hot-climate use and say dealers told them the loss was normal and not covered, while others mention software updates that they felt made range estimates or regenerative braking behave differently. A few describe the charge and range display jumping or disappearing while driving. Mostly reported in the first few thousand to about 30,000 miles, often after a year or more in hot climates; later reports come from high-mileage used purchases.

   What to check: Read the capacity bars on the dash and compare them with the age and mileage, and confirm actual range on a test drive rather than trusting the range estimate. Ask for battery health history and whether campaign software updates were applied.

   “The problem is the battery, we where told by Nissan that there would be a slow loss of capacity and up to 20% loss at 5 years. This is only in hot climates like arizona, tx and ca. The car should have had a battery cooling system. Now after pay $40,000 for the car in the first year my driving range is down so much in my second year the car will be worthless to drive or sell.”

   NHTSA complaint #10469914, filed 2012-08, 22,000 miles

   “The range meter on the right side of the dash shows incorrect range. I understood when people would say it depends on how you drive, but no matter how I drive there is no possible way for me to get the range the car says I have. If it shows 55 miles I can be sure to get between 20 and 35 miles before being stranded. I contacted Nissan for a warranty or service concern and they claimed it not to be a manufacturer defect.”

   Air bags

   Passenger seat occupant sensor failure (airbag light)

   • 34 complaints (36%)
   • median 60,700 mi at 8.5 yrs old (20 state mileage)
   • owner-quoted repair $3,000 (median of 19 quotes)
   • filed 2015–2025

   Owners describe an airbag warning light that flashes or stays on and a dashboard message showing the passenger airbag off. Dealers diagnose a failed occupant classification sensor (owners cite codes B1018, B1013 and B00A0) and say the sensor is built into the seat, so the fix is replacing the whole seat cushion assembly. Quoted costs commonly run from about $2,600 to over $4,000. Several owners note that later Leaf model years were recalled for a similar condition but the 2011 was not, and some report resetting the code only for it to return after a few miles or weeks. Reported from roughly 35,000 to 110,000 miles, most often in the 50,000-90,000 range; one owner linked it to liquid spilled on the seat.

   What to check: Turn the key on and watch the airbag light and passenger airbag status display through a full self-check. If the light flashes or the passenger bag shows off, ask for the stored codes and whether the occupant sensor has ever been reset or replaced.

   “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. …”

   NHTSA complaint #11193208, filed 2019-04, 78,300 miles

   “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.”

   Brakes

   Grabby or inconsistent brakes at low speed

   • 17 complaints (18%)
   • median 12,000 mi at 3.4 yrs old (17 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2011–2020

   Complaints describe brakes that grab and release, producing a jerky or lurching stop below about 20-25 mph, and occasionally a momentary loss of braking force or a delay before the pedal responds. Some owners say the car keeps rolling briefly after the pedal is released, and a few report very little braking force right after start-up. Dealers are described as reprogramming the brake software, turning rotors, or finding nothing wrong, and several owners say the symptom returned. Reported from delivery mileage up to about 100,000 miles, most commonly under 50,000 miles; several owners note it is worse in warm weather or after a short key-off.

   1 related service bulletin

   What to check: Test drive at low speed in a parking lot and try several light, repeated stops, including after switching the car off and on. Ask whether any brake control software updates or repairs were performed.

   “I have definitely noticed the braking assist displaying a mind of its own, though never on the freeway as yet. Sometimes I just tap the pedal and the brakes apply much more than I was pushing. Other times the brakes apply normally, but do not release immediately after releasing the pedal. Nissan...something is up here.”

   NHTSA complaint #10422865, filed 2011-09, 1,000 miles

   “I noticed the braking defect soon after taking delivery of my LEAF. Similarly to the other respondents, the continuance to braking after the pedal has been released occurs at any speed and without warning. I have had it happen at parking lot speeds, on the freeway, and at all speeds in between. I have been unable to discern any particular situation that seems to 'cause' the phenomenon. …”

   Electrical system

   Power loss or electrical shutdown while driving

   • 13 complaints (14%)
   • median 30,000 mi at 5.5 yrs old (13 state mileage)
   • filed 2011–2021

   Owners describe sudden loss of power or a dashboard shutdown while driving, sometimes requiring a restart at the roadside, and a few report the car would not start or would not shift out of park. Others describe 12-volt battery and accessory problems, including windows, door locks and charging faults, and one report of smoke and a burning smell from the on-board charger area during charging. Scattered from very low mileage to over 100,000 miles; several reports involve the first few thousand miles.

   6 related service bulletins

   What to check: Ask about 12-volt battery age and any history of warning lights or no-start conditions, and check that windows, locks, keyless start and charging all work during the test drive.

   “When I accelerated from a stop on a city street to turn left on my way home the engine lost power even as I pushed the accelerated pedal more till the car almost stopped in the middle of the turn. Engine returned to normal acceleration power after I prepared to pull over out of traffic. No warning lights came on.”

   NHTSA complaint #11413725, filed 2021-04, 44,000 miles

   “About a month and a half ago, I purchased a 2011 Nissan LEAF from my local dealer. Everything was going great until about a month ago when I was driving on the highway around 20 MPH or so when the power suddenly shut off. The entire dashboard instantly went off but the radio+touchscreen remained on. The car came to a crawl and I was able to pull over and restart without any problems. It was a little scary to say the least. I called the dealership where I bought the car from and left a voice mail for the service dept. …”

Buying note. On a 2011 Leaf, the passenger occupant sensor and the brake feel are the two things most worth checking in person, since both are described often and the sensor repair is quoted at a large share of the car's value. Also confirm remaining battery capacity bars and real-world range, and ask for service records showing which software campaigns and updates were completed.
