2014 NRG, manufactured in April, purchased in Sept 2014, now 48K miles.
Sitting in the dealer lot for too long, the battery needed jump start when I test drove 3 years ago, probably shortened the battery life. 38 month life is short compared to other cars, but seems normal for C Max. Can any other CMaxers confirm the correlation between battery life and the period from manufacture to purchase?
The car couldn't start yesterday morning and sent SMS to my phone. Charged HVB for 20 min and survived the day with a round trip. Today with full HVB charge, it still works. However, the 12V battery has only 8-9V with trunk open (a few lights on). The 12V battery voltage drops quickly after charged to 11V or so.
