Seeing many of the 12v posts lately makes me wonder why that could be....
I'm not surprised about all 12v posts lately,
perfect timing for a Karma with original battery installed.
On average, a car battery lasts from 5 to 7 years. A fully charged battery should read 12.6 volts or more (with the engine off).
Just replace the battery when in doubt … lost wakeup signal is a true nightmare.
