Orbie Posted September 24, 2019 Report Share Posted September 24, 2019 Hi All, I've had my ST now for about 4 months, it's been very reliable up to a few days ago. For some reason if I don't drive the ST for a day, the next day I'll come out in the morning to start or get in the car and the battery will be completely dead. This has now happened twice in the last 3 days. I haven't changed anything on the car, it is stock, the only thing I have plugged in is my ipod in the front console (wireless charging compartment). I've had that thing plugged in there since day 1 of ownership. I've been able to go multiple days in the past without driving it and it starts up fine. Is anyone else seeing continuous dead battery issues on their ST's? I don't think it's unreasonable to think I can leave drive my car for a couple of days and not have it die on me. Thanks!

1004ron Posted September 24, 2019 Report Share Posted September 24, 2019 It could be a number of things, parasitic draw, battery failing prematurely, ...... With it being new , my suggestion would be to have the dealership do a parasitic draw test and a battery load test. You could also get the battery load test done at free at places like Autzone, and at least you'll know before heading to the dealership. 1 Quote Link to comment Share on other sites More sharing options...
Orbie Posted September 24, 2019 Author Report Share Posted September 24, 2019 Thanks 1004ron! much appreciate the advice and feedback. I'll follow up on the battery load testing see if there is anything there. Sounds like I may be in the minority on this issue so something unique going on.

akirby Posted September 24, 2019 Report Share Posted September 24, 2019 Make sure they use something like a Solar BA7 tester. The old style load testers don't work on modern batteries. You want to see the CCA rating compared to what it was new. 1 Quote Link to comment Share on other sites More sharing options...
Orbie Posted October 5, 2019 Author Report Share Posted October 5, 2019 Just an update here in case it helps anyone else, had the dealership do a parasitic draw test and test the battery itself. The parasitic draw test came back negative, but the battery itself failed load testing so they replaced the battery under warranty. Crazy that a battery would fail in 4 months of ownership so hopefully it's just an oddity. Will update this thread if anything further happens down the road. Thanks for all the replies and feedback! 1 Quote Link to comment Share on other sites More sharing options...
akirby Posted October 5, 2019 Report Share Posted October 5, 2019 Even new batteries can fail sometimes with a dead cell. Probably won’t happen again for at least 3 years. 1 Quote Link to comment Share on other sites More sharing options...
mvan231 Posted October 8, 2019 Report Share Posted October 8, 2019 I am having a similar issue on my 2016. It seems to be the worst when it has sat overnight or for at least 8 to 10 hours. I am going to get a battery test done and see what happens with the results Quote Link to comment Share on other sites More sharing options...
