Nissan Murano faulty computer module causing battery drain, unresolved issue on Nissan Murano

Some Nissan Murano owners report experiencing persistent battery drain issues potentially caused by a faulty computer module. These owners have noted that a parasitic power draw can occur when components continue to draw current even after the vehicle is turned off, often due to malfunctioning parts. To diagnose this issue, some recommend testing for parasitic power draw using a multimeter after disconnecting the negative battery cable. Additionally, a faulty battery current sensor may lead to chronic undercharging and battery drain by providing inaccurate information to control modules. Owners who have installed aftermarket parts have also reported sudden increases in battery drain, suggesting that these components could be the source of the problem. Furthermore, some have experienced significant parasitic drain due to software or firmware bugs, which may require updates or reprogramming to resolve. If the battery drain issue persists, it is advisable for owners to consult a mechanic or dealership for further inspection and potential module replacement.
