Battery dead. Had similar problem last year. The mechanic replaced the battery and battery died following day. Performed a diagnosis and replaced the control module under drivers side seat. Said module was draining battery when car was not in use.

Is this same problem a year later due to an incorrect diagnosis or something different.
Do you
have the same problem?
