Honda Civic ( not a hybrid) with 137k miles has had inconsistent starting issues since last Spring. I had a new battery installed in March of 2014, and it still had inconsistent starting issues. It acted as if it wanted to turn over, and then finally would after 2 or 3 turns of the key. Some days it started just fine, too. The mechanics that replaced the battery said that they battery was fine and then they could not find any issues. It still continued and I brought it to a different mechanic after a jump 6 weeks after the new battery was installed. They put a new starter in, and said that the seams or seals were worn and drawing too much power from the battery. That starter was replaced in May. Once again, and over the last couple of days the car is not wanting to start. It is cranking, but takes 2 or 3 turns of the key. Sometimes it has started just fine, and it started for the mechanics just fine this morning.
Simple things I’ve ruled out: regular oil changes, a full tank of gas, not sitting outside in cold weather, and not sitting for long periods of time. An idea is that something might be drawing a current from the battery while the car is off.
Thanks for any ideas!
