Nissan Leaf Won't Start? What Owners Report
52 of the 1,092 owner complaints NHTSA has for 2008–2024 Leaf models describe a car that won’t power on or start. Here is which years and systems show up most, what owners say, what to check first, and when a mobile mechanic can fix it where the car sits.
NHTSA data pulled September 2026.
Turn on the hazard lights if they work, get out of traffic and call roadside assistance. Never touch orange high-voltage cables or open the high-voltage battery.
Which Leaf years report it most
Reports peak with the 2015 model year (10). A year with more cars on the road usually has more reports, so use this to know what to ask, not to rank years.
What else these reports mention
Owners filing these complaints most often also named the electrical system and brakes – usually where a mechanic starts looking.
| System named | Reports | Mobile mechanic? |
|---|---|---|
| Electrical system | 32 | Often in the driveway |
| Brakes | 27 | Usually on the spot |
| Fuel system | 10 | Diagnose first |
| Transmission and drivetrain | 5 | Usually a shop |
| Throttle and cruise control | 3 | Diagnose first |
| Engine | 3 | Diagnose first |
What Leaf owners describe
“Additionally, the 12 volt battery would not charge, and the doors would not unlock to open.”
“This is caused by a defective dc-dc converter that fails to properly charge the 12v battery, risking and repeatedly causing sudden loss power, loss of braking, and loss of safety critical functions.”

| 2024-09 | 24V700000 | 2019–2020 | Electrical system | A quick charging battery that overheats increases the risk of a fire. |
| 2024-02 | 24V071000 | 2018–2022 | Driver-assist systems | A rearview camera that does not properly display an image can reduce the driver's rear view, increasing the risk of a crash. |
Safety recall repairs are done free by the brand's dealers. A mobile mechanic cannot do recall work. Enter your 17-character VIN at nhtsa.gov/recalls to see open recalls on your exact car. "Park it" means NHTSA and the maker say not to drive the vehicle until it is fixed.
What to check first
- Try the key card or phone key again, and check the maker's app for alerts.
- A weak or dead 12-volt battery is a common reason an EV will not wake up – it powers the computers that switch the main battery on.
- Check whether the car was plugged in and whether charging stopped with an error.
- Look up the owner's manual procedure for a dead 12-volt battery – it is different from a gas car.
