I guess I should be more clear. The warranty that came with 2011 LEAFs specifically says:LTLFTcomposite wrote:I didn't know leaving a LEAF run down for 14 days voids the warranty. I was planning to pick up a used one at OLO this weekend, for all I know it has been left dead for lengthy periods. Would that show up on the battery health test the dealer runs?
"This warranty does not cover damage or failures resulting from or caused by:
Exposing a vehicle to ambient temperatures above 120F (49C) for over 24 hours.
Storing a vehicle in temperatures below -13F (-25C) for over seven days.
Leaving your vehicle for over 14 days where the lithium-ion battery reaches a zero or near zero state of charge.
Physically damaging the lithium-ion battery or intentionally attempting to reduce the life of the lithium-ion battery.
Exposing the lithium-ion battery to contact with a direct flame.
Charging the lithium-ion battery full on a daily basis despite the lithium-ion battery keeping a high state of charge level (98-100%).
Immersing any portion of the lithium-ion battery in water or fluids.
Opening the lithium-ion battery enclosure or having it serviced by someone other than a Nissan LEAF certified technician.
Neglecting to follow correct charging procedures.
Use of incompatible charging devices.
Consequential damage caused by the failure to repair an existing problem."
AFAIK no one here really knows what exact data is sent to Nissan so it's to know if Nissan would have any idea unless the pack got so low that the LEAF wouldn't even try to charge it back up.
What's interesting is reading the service manual there is a DTC for low total voltage. It doesn't mention this as a possible cause but does have you check each module's voltage and if not 5 volts then it tells you to replace it, may have to replace them all if this was the cause
