Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Car is under a recall-no level 3 charging due to risk of fire since October of 2025 with no remedy in place. The car is not able to be used as advertized-cannot travel outside of 200 miles from my home as level 3 charging is not possible and level 2 charging not feasible for travelling. Of note-the battery in my car is a NEW battery -it was replaced in December of 2025 due to repeated prior failures -including suddenly slowing down drastically on highway which was a safety hazard. …”

NHTSA complaint #11721845, filed 2026-03

“The high-voltage battery on my 2021 Nissan LEAF is subject to Recall 25V-655/R25C8. The recall notice states that the battery cells can develop excessive lithium deposits, which increase electrical resistance and can cause rapid battery heating during Level 3 fast charging. Nissan instructs owners not to use Level 3 charging at all until a “remedy” is available. I have attempted to have the car fixed at two local dealerships, with both stating that they do not have a fix available. …”

NHTSA complaint #11714582, filed 2026-01

“So on October 1st, my car, my nissan Leaf went into turtle mode for the first time. And then yesterday, while I was on the highway, it went into turtle mode, dropped down to 50 miles per hour, and I got off the highway, and the car wouldn't move anymore. I had to turn off the car, wait a couple minutes, and turn it back on, and then it worked again. I was told to contact the dealer to get a car rental. The dealer said that they don't have any loaners available and that other customers are waiting. …”

NHTSA complaint #11772696, filed 2026-10

“The 62kWh High-Voltage Lithium-Ion Battery Pack. The vehicle is currently in my possession in Santa Fe, NM, and is available for inspection. It exhibits physical degradation (40.07% Hx) directly linked to the cell defects described in Recall 25V655. The vehicle is a documented fire risk. Per Recall 25V655, internal lithium deposits create resistance that leads to thermal incidents. Because my battery already shows terminal degradation (40.07% Hx and 3.18V sag), the risk of a fire during charging or operation is imminent. …”

NHTSA complaint #11727594, filed 2026-03

“I am submitting this letter as a formal safety complaint concerning NHTSA Recall No. 25V655000, which affects my 2021 Nissan LEAF SV and results in the continued restriction of DC fast charging due to a reported fire risk, without an available or timely remedy. Under this recall, Nissan has restricted the vehicle’s ability to safely utilize DC fast charging. While I understand and support actions taken to mitigate fire risk, the absence of a corrective repair or defined resolution timeline has effectively removed a core operational capability of the vehicle on an indefinite basis. …”
