Parasitic battery drain. Car is rendered inoperable after periods of non use. The batter has been replaced and the problem persists.
Battery dies and vehicle is unable to start after short periods of being turned off. This has left me stranded in unsafe areas and can pose a major safety hazard.

BATTERY DRAINED EVEN THOUGH I LEFT NO LIGHTS ON AND HAS HAPPENED MULTIPLE TIMES. HAD TO REPLACE BATTERY TWICE IN LESS THAN A YEAR. HAD BATTERY TESTED AND IT WAS GOOD. HAD TO JUMP MY CAR MULTIPLE TIMES FOR DEAD BATTERY WHILE AT WORK. VEHICLE WAS PARKED IN A PARKING LOT.
WHEN DRIVING MY 2018 SUBARU WRX PREMIUM IN THE HEAT WITH THE A/C ON IT IS CAUSING EXTREME DRIVING CONDITIONS WITH THE CAR STUTTERING CAUSING FLUCTUATION IN SPEED WITH THE CAR DRAGGING THEN PROPELLING DRAMATICALLY DUE TO THE TURBO ENGAGING. THE ERRATIC CHANGE IN THE PERFORMANCE OF THE CAR IS NOT NORMAL AND IS CAUSE FOR ATTENTION FROM THE MANUFACTURER. I WAS DRIVING ON THE FREEWAY AND THIS PULLED SUCH AN EXTREME DRAIN ON THE CARS ELECTRICAL SYSTEM AND COOLING SYSTEM IT ALMOST MADE MY CAR OVERHEAT IN THE MIDDLE OF FAST MOVING TRAFFIC. MY CAR IS WELL MAINTAINED AND DRIVEN RESPONSIBLY. I HAD MY FAMILY IN THE CAR AND THIS COULD HAVE CAUSED A TRAGGIC SITUATION AS THE FREEWAYS HERE IN CALIFORNIA ARE VERY UNFORGIVING.
