I have outlander 2014, If I parked 1.5 - 2 days my 12v battery goes down around 4v . vehicle cant start, I had to jump start, first i think its 12v battery problem, but I replace new battery also. same fault happens. when i jump start and drive little distance around 5km , battery will fully charge. and i can start around 1.5-2 days without jump start. my drive battery also in good condition. several technicians including Mitsubishi motors checked, but nobody found any fault. please comment me do you have any idea?
