Hey guys, I got the high battery drain message a few days ago after going grocery shopping, but the car started fine when I came out so I figured I forgot to turn off the radio or something. Fast forward the next morning, I hop in the car to start it and the ignition comes on normally and everything but when I press the start button, the starter is super slow to turn, everything dims, but the engine does start. I am immediately presented with a bunch of abs faults and power steering faults due to low voltage. I let the car idle and charge, turn it off and back on immediately, and everything is fine. So I tried to find a drain, measured all the fuses with the car in deep sleep and nothing was drawing power. Comfort access isn’t draining it. Next morning the car wouldn’t even start, battery was too low. I had to jump it from the terminals under the hood. Drove around for an hour to charge the battery, then parked and unplugged the TCU overnight and it still drained. Next morning wouldn’t start. So repeat above process, except this time I unplugged the IBS and the car seemed to not drain overnight. Started fine and I thought “finally found the culprit”. However, I went to wash the car and because of how my hose is positioned I have to turn the car around to wash the other side. Pulled it to the spot I wash in, washed one side, got back in and turned the car around, washed the other side, then went to pull it back to where I park it and: wouldn’t start, had to jump it. I’m now at a loss. Battery is just now turning 3 years old, so I doubt that’s the problem. Voltage regulator maybe? I thought it wouldn’t be alternator related since it seems to be charging the battery fine (14.6 V at idle) but I really am not sure now. I’ll post some pics of ISTA codes when I get back to my computer but they all seem to be normal low voltage codes. Any help would be appreciated.
