My 2022 Ascent stands for a week or so at a time and suddenly one day the battery died. Charged it and measured it - Battery was rubbish and Subaru tested it and replaced it under warranty - hoorah! BUT a couple of months later (now out of warranty ) damn thing dies again after not being driven for 10 days. Now I did some measurements - charged it up and tested every couple of days. This "new" battery wouldn't charge to much over 12,5V - so first off the battery that the dealer out in was definitely not a premium one. After 7 days was down to 11,1V at which point starting the car became dicey. Took it to the dealer thinking that the replacement battery was C@@p and suggested it needed to be replaced under warranty. Dealer checked it and said battery was ok. MMM - Asked dealer to test the so called "Dark current" - that's the draw while the car is switched off. The dealer answered that they measure it at 0.19Amps! I made sure that this was not an error and the dealer insisted that this was "normal" as they "knew" from other cars that this was a normal draw! OK so math is not the dealer's strong point and I tried to point out that 190 mAmp draw will kill the average battery in about 8 days!
I may as well have discussed the theory of relativity. So went to the National Customer Service line and repeated my request for clarification on this massive Dark current number. Got absolutely blown off by them with a stupid answer to the effect that Customer Service does not have any technical or diagnostic knowledge and that I should refer to the dealer. I have been around cars for over 60 years and have never seen a dark draw much over 70 mAmp. Obviously the dealer doesn't have a clue about this or does not want to get involved in a difficult issue, so I must now try to suss out wtf is going on.
Anyone had a similar experience and maybe cast some light on possible solutions? Scuse the long drawn out post!
