2021 Nissan Leaf electrical system problems

“I purchased a 2021 Nissan Leaf used on 9/9/2026 from CarMax Burbank with unrepaired NHTSA recalls 25V-655 and 24V-700 documented in my sale paperwork. The salesman told us they were simple recall repairs, nothing to worry about. When I took the car in, the authorized dealer's service advisor warned that the recall reprogramming could likely leave the vehicle inoperable if a battery fault code appeared, and recommended returning the car to CarMax because it was on a stop sale with no batteries available. A CarMax service consultant dismissed the warning as a scare tactic from that specific location, said they couldn't consider taking the car back unless we tried the recall repairs, and sent us to a different "partnered" Nissan dealer. On 10/21/2026, that dealership location recommended the LBC/VCM recall reprogramming, kept the vehicle eight hours, and released it as repaired and drivable. Less than 24 hours later, on 10/22/2026, while driving on the highway in heavy rain in moving traffic, the battery failed with [Warning, Service EV System, Power Reduced]. The vehicle was towed to the dealership on 10/23/2026, where the dealer confirmed the EV battery failed,…”

“My Leaf started displaying dramatic battery range reduction and charge fluctuation symptoms XXX at 98K miles. 1st available appt at dealership (as advised by Nissan) was XXX, now at 115,000K miles. XXX I received recall notice in my mailbox from Nissan re 25V-655 - 8 1/2 months past the issuing of recall - explaining the defect and fire hazard while fast charging. I now realize the "hot" smell I detected while fast charging was the overheating of lithium - thank God it didn't catch fire back then as I had been napping in my vehicle with my dog. At the dealership, service dept said my battery failed the post update test; sent me home in (ice) loaner car; said Nissan will reach out within a few days. Finally receive call XXX from [XXX] on behalf of Nissan North America; received 1st buyback email "offer" Sept 4, 2026 nearly a month after my car was deemed inoperable (this was a Friday at 4:59pm at the start of a major holiday weekend). They requested I pay them $9,411.11 so they can recover title from lender; same unchanged offer XXX after "escalation" review. A down payment + over 4 yrs of never missed consecutive payments - $33,000 later - and they are…”

“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.”

“Recall for FAST CHARGE LEVEL 3 CHADEMO has been issued for over 6 months. I am advised not to fast charge due to risk of devastating fire. Very dangerous to continue to use this car in an urban setting. Buyback was denied and told to wait for a fix. No fix yet! I can't get out of Philadelphia in this car. Tesla wouldn't let this happen!”

“Level 3 quick charging was not working, and only Level 2 charging is working now. That creates a risk of not working if Level 2 charging does not work as well. Nissan issued the letter on 3/18/2026 to recall but not yet provided the detailed repair plan as of today. Please advise. [XXX]”

“I own a 2021 Nissan Leaf with an open safety recall (NHTSA Recall 25V-655, Nissan Recall R25C8) issued on September 30, 2025. The recall involves a battery defect that creates a safety risk during DC fast charging (Level 3). As a result, I am unable to use public fast-charging networks such as EVgo. The recall currently has no remedy available and has been unresolved for over 7 months. I do not have access to home charging, and without fast charging, the vehicle cannot be used in a practical or reasonable way for daily transportation. This has resulted in a complete loss of use of my vehicle and has impacted my ability to work. Nissan has not provided a timeline for repair or an alternative solution such as a loaner or rental reimbursement. This delay is not reasonable, and I am requesting investigation into the lack of remedy and the impact on vehicle usability.”
