What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2026 Nissan Leaf, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
The contact’s daughter owns a 2026 Nissan Leaf. While the owner was driving 70 MPH with the ProPILOT Assist engaged, a semi-truck merged into the lane and crashed into the vehicle. Following the impact and the deployment of the front air bags, the driver was able to safely maneuver the vehicle to the side of the highway. The button to engage the parking brake was activated, the vehicle was shifted in park(P) and turned off. However, after exiting the vehicle, the vehicle failed to shut off and the electronic parking brake failed to hold as intended, and the vehicle rolled back onto the highway and crashed with two other vehicles. The vehicle had damages to the hood, front bumper, windshield, and the front bumper reinforcement bar was bent. A Police report was filed. The owner sustained injuries to the face, neck, and shoulder due to the force of the seat belt and air bag deployment. The driver was currently receiving physical therapy for the injuries. The manufacturer was notified of the failure. The failure mileage was 5,000.
The car had a faulty dc/dc converter one month after purchase. The vehicle has about 900 total miles. Part number 292A0-8342R

Potential garage/house or parking lot fire as there exist reports of 2026 LEAFs spontaneously combusting in North America. Vehicle is currently at Nissan dealership service department for inspection and diagnosis.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
