Cold start ICE rough start
My car always made a bit of a "soft knocking" noise when the ICE would start up, but the past few months I've noticed it's making a much more rough knocking noise and vibrating the entire car for a couple of seconds before settling down.
If it makes a difference, I rarely use the car in Sport mode (maybe 50-100 miles/month). Also I feel like the engine noise while driving in Sport mode is louder than it used to be (sounds very rough). I understand Karmas are generally noisy when in Sport mode, but this seems louder than some videos I've seen of other Karmas.
Is this a typical issue with the IC engine? Any ideas what the issue could be? Also, perhaps a stupid question, but if it's only the ICE that needs servicing, can that be done by any mechanic (as long as they know the jacking points on the car), or should it only be done by a Fisker/Karma mechanic?
Thanks in advance!
