High-Voltage Lithium-Ion Battery
LimitedWarranty
BMW of North America, LLC (BMW NA) warrants
the high-voltage lithium-ion battery assembly
against defects in materials or workmanship for a
period of 8 years/100,000 miles, whichever
occurs first.
High-Voltage Lithium-Ion Battery
Capacity Coverage
The high-voltage lithium-ion battery modules are
covered against excessive capacity loss for a
period of 8 years/100,000 miles, whichever
occurs first. This coverage is in addition to the
high-voltage lithium-ion battery’s limited
warranty for defects in materials or workmanship.
Due to its inherent technical design, the
high-voltage lithium-ion battery’s capacity will
decrease over time and with use. If an authorized
BMW center’s capacity check concludes that the
net battery capacity is less than 70 percent of its
original nominal value when it was new, this level
of capacity loss is considered excessive.
During the High-Voltage Lithium-Ion Battery
Capacity Coverage period, BMWNA will cover
the necessary component repair or replacement
to correct this excessive capacity loss when
performed by an authorized BMW center.
Battery performance and durability, including
high-voltage lithium-ion batteries, is
temperature-dependent.While battery capacity
increases in higher temperatures, colder
temperatures will lower the battery’s capacity.
Extreme high and/or low temperatures may
impact the battery’s service life.
