The battery & alternator checks out fine. There is a draw on the battery when the car is off. Service Tech (auto/electrical) can't locate the draw. The daylight running light module (DRL) had to be replaced last week; I noticed the charging issue at the same time. As long as I drive the car each day, the car will start. However, if I let it set unused for a couple of days, it won't start without a jump. All lights & electrical devices are working fine. We just can't find the draw location. Thank you, John Morgan, USMC

If you have interior lights that delay, you might want to check that.

Thank you for that information…I am taking the car in for a battery drain (Parasitic Draw Test) test this week. Hopefully, that will provide an answer. I will be sure to test the interior lights. Thanks, John Morgan, USMC
