Gen6: Battery dies in seconds after 3days
Hey guys, I've got a problem I just can't figure out...
I have a dec 2015 Chevrolet Camaro RS Coupe V6 (~335hp), US import from Florida. I’ve owned the car since last summer and it had absolutely no issues until around February this year.
Since mid February, I’ve been having a strange battery drain issue: The car starts and drives perfectly fine during daily use (about 50 miles per day). But right now, if it sits for around 3 days, the battery suddenly becomes completely dead from one second to the other, always on the third day and the car won’t start anymore. It's not even a slow start anymore.
Some important details that could help:
- Battery was replaced around october 2025 with a Varta Dynamic SLI 12V 72Ah battery
- Before this issue started mid february, the battery went dead twice because the car sat too long without driving in cold winter weather
- After jump starting, everything worked normally again
- Workshop checked resting current/parasitic draw but found nothing abnormal with no error code
- The alternator seems fine while driving
Also 1 weird symptom: Normally the parking sensors only beep while reversing. But sometimes after unlocking the car with the keys while the car is parked, it randomly starts making irregular parking sensor beeping noises even though the car is not driving in reverse. The car has just been opened...
Has anyone experienced something similar on a 6th gen Camaro? I don't plan on selling my baby since it's my dream owning a camaro since childhood! Looking for serious help :/
