Or have someone small enough to get into the trunk while you close it to see if the light stays on. Check it several times.
Has anyone had a constant battery drain? I've had the car in 11 times and was finally told it was because I had an after market alternator installed. But the thought from other mechanics is that there is something running that randomly does not shut off when the car is off but can't locate what that something is. Below is what I've gone thru. Any thoughts?
8/2017: Dead battery replaced at Auto Zone
9/2017: Dead battery; was jumped but alternator and battery were testing good; “must have been a fluke”
11/17/17: Dead battery; GL Hyundai said Autozone gave me a bad battery; Autozone replaced the battery under warranty
12/27/17: Dead battery; GL Hyundai said it’s because it is not a Hyundai battery and replaced it with Hyundai battery
1/5/18: Dead battery; GL Hyundai said it was fine; teo hours later called me back and said it was the alternator & $727 to replace
1/6/18: Took to local mechanic and replaced alternator for $359
1/15/18: Dead battery; GL Hyundai replaced the battery under warranty because old alternator supposedly drained it
2/5/18: Dead battery; towed to local mechanic & said alternator is fine; must be something running that is draining the battery when the car is off; taken to GL Hyundai
2/10/18: GL Hyundai said bad alternator because it is not an OEM alternator
2/12/18: Local mechanic can warranty out current alternator for Hyundai alternator for $214 but still don't think it's the alternator
