So I finally bought a Karma for my garage. Gorgeous car, beautiful lines (Inferno/Dune--only 8k miles), but understandably there are issues that I am aware I'd have to deal with. I am a gear head, but some of this is foreign with the hybrid/electric stuff.
Congratulations and welcome to the Fisker community. By long standing tradition, I have to ask you to post a few photos of your new acquisition when you get a few minutes. We never get tired of looking at photos of Karmas, our own or others'. Also, the Search option on the forum is a great tool to find out information that has been discussed before, particularly the pearls of wisdom that have been provided by our resident experts over the years.
The HV battery: mine appears to have been replaced in September of 2012. But I do not know where to find the serial number nevertheless. I noticed my check engine light came on, and so I performed the soft reboot which did not work, but then performed a hard reboot of which cleared the check engine light (unplugged the connector, waited a minute, plugged back in, lock and unlock doors).
The check engine light (also referred to as MIL or CEL) comes on for a variety of reasons and clearing it with a hard reboot wipes out the codes stored by the module that requested the light, and is not the best way to turn the light off. It would be better to get an OBDII code reader to download the codes and clear them using the scanner. The codes you get from a generic scanner are not very precise, but they could be informative based on our collective prior experience. It's also a lot easier and less traumatic to the car to clear the MIL using the scanner than by doing a hard reboot.
As for the serial number, etc. I think a CSP like
@FiskerPhilly or
@Harleyguy can use a Fisker diagnostic computer to get the information without having to drop the battery out of the car, which is a bit of a production.
The car takes about 11 hours for a full charge and that appears to be typical and thus can I assume the check engine light is a false positive? If it were the HV battery, wouldn't I see slower charging times or rapid depletion of the battery when in stealth mode?
11 hours would actually be pretty good if you are using the portable charger that came with the car and 110V household plug. You can cut that time in half if you upgrade to a 240V Level II charger, but if you don't drive the car a lot, the 110V charger may be adequate for your purposes. As I said before, without reading the code and deciphering it with Fisker's custom diagnostic software, it would be impossible to know what the issue was that caused the MIL to illuminate. Depending on which software level this car has loaded, you can expect to see false MILs from time to time. The later software tends not to do it as often as the earlier software revisions. But there are also legitimate reasons for the MIL to come on. It is impossible to say without reading the codes.
Thanks! New to the Karma.
