Car Defect Radar
Built from NHTSA complaints and recalls collected for this model, generated September 22, 2026. Totals reflect what has been collected, not every complaint ever filed.

Recalls

Safety issues the manufacturer must repair for free. A recall means confirm the fix was done, not walk away.

This is a report of what I think is a safety issue with the Leaf vehicle but has not caused an accident or incident for me, yet. If the Start button is pressed and then the Shift Control is changed to quickly the car will be put into Neutral instead of the desired Drive or Reverse. If the driver does not realize this and removes their foot from the break when the car is on a steep hill the car could roll into a vehicle, pedestrian or other obstacle before the surprised driver has a chance to break. The Leaf vehicle should not go out of Park if it is not ready to go into Drive or Reverse when the driver is trying to shift it into Drive or Reverse.

Incident Summary & Ineffective Recall Remedy: I am reporting an acute high-voltage battery cell collapse on my 2021 Nissan LEAF (VIN: [XXX]). The vehicle previously received the software update for NHTSA Recall #25V655 (Nissan Recall #R25C8) at Kings Nissan. The software patch failed to repair the underlying defective battery hardware. Following a second service visit on XXX where Kings Nissan tested only the auxiliary 12V lead-acid battery to dismiss my complaint, I purchased an independent CAN-bus diagnostic tool. On XXX (63,702 miles), LeafSpy telemetry confirmed Cell #31 is severely degraded, exhibiting a 191–307 mV voltage collapse. This causes sudden dashboard state-of-charge drops from 70% down to 42–45% on active highways, forcing emergency power limits ("limp mode"). Refusal of Post-Remedy Service: Despite active Corporate Case #XXX with Nissan Consumer Affairs, authorized dealers (Kings Nissan, Nissan of Queens and Nissan of Staten Island) refuse to intake, scan, or ground the vehicle, leaving a severe hardware hazard active on public roads. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Brakes problem: During rain season the moisture can get into the brake system. When backing up, the brakes feel partially seized, and make squeeze sound. The problem is more serious when pulling the parking brake during overnight parking. Somehow the sound is coming out of front brakes. The sound will diminish after break several times during normal breaking. Forward Collision warning system: The system only alerts driver with deeps and lights on dashboard. It doesn’t enables the brake system to slow or stop the car.

This vehicle failed to have airbags deployed in this accident on 3.23.2022, as photographs that are larger than 10MB will upload, but the Estimate did upload. BUT the car was spun nearly if not fully 360 after hit by a truck in a lane change of a blind spot that spun the car and into concrete barriers. HORRIBLE. Totaled Vehicle. this is the SECOND accident both under USAA on September 03, 2021, with another Police Report and Freeway accident from Front End when freeway traffic came to a sudden stop, and into the barrier. AGAIN no Air Bag Deployed. Warning systems failed.

The dealership without our knowledge or approval did an update on our car last November that makes the heater and more importantly defroster not work when it's colder than about 17F degrees outside. This causes the vehicle to fog up all over including the windshield making it dangerous to drive. After about 10 minutes it finally starts working. We've told them about it numerous times and even saw other Leafs at the dealership for the exact same thing on the first cold day last winter after the update. They haven't yet gotten a fix for it and said it's on purpose. As far as us owners can tell they aren't looking into any sort of fix. They say we should just start the car for 10 minutes without driving but that doesn't work. You can leave it run for 30 minutes and the heat doesn't turn on. It only works after 10 minutes of dangerous driving. Besides we shouldn't have to run a vehicle for 10 minutes before driving. There are numerous examples of emergencies that require immediate driving. Please look into this as every Leaf owner is dealing with the same dangerous conditions in the northern states and I assume Canada.

Is 55 complaints a lot? They were filed between 2021 and 2026, roughly 11 a year, which is more than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.
