2013 Buick LaCrosse battery being drained while off

Asked by Justin447733 Jan 25, 2020 at 10:42 PM about the 2013 Buick LaCrosse Leather FWD

Question type: Maintenance & Repair

I have a 2013 Buick LaCrosse V6. It has only
34,000 miles. I have owned the vehicle for
only 4 months now and the battery has
started to die the past 2 days now so I have
been having to get a jump to start it. I have
had the battery, alternator and starter checked
and they are all perfect. Something is draining
the battery while the car is off still. Any help or
suggestions please would be greatly
appreciated. Ps I also have checked all
interior lights including trunk light while vehicle
is off and nothing is left on.

How old is the battery? It might just be time for a new one.

I just had the battery starter and alternator all checked and they are all perfect. Even after having to get a jump just to get to mechanic to check those things the battery is good they said. They say there is something pulling power from battery even when the car is off. I have no clue.

I had this problem in my 2013 Dodge Journey, after purchasing 3 batteries (2 were faulty) the problem ended up being my spark plugs.


A sulfated battery can lose it's charge quickly, or it may not reach it's full charge, you have to do a proper load test and not a simpler check for voltage. That said, if you are certain battery is good, and you feel a parasitic drain is killing it, then you'll have to trouble shoot for that drain. Lots of guides online for that. If the drain is killing a fully charged batter in mere hours then it has to be a major component draining it, like an electric motor not turning off. (Cooling fans for instance.) Most minor parasitic drains take days to kill a charged battery.
