NHTSA Complaint #11470160 — 2019 SUBARU ASCENT

What component or system failed or malfunctioned, and is it available for inspection upon request? Battery was drained completely when rear hatch is opened for the short period of time to unload stuffs from the car. Similar situation happened when the car was about a year old. When rear hatch was opened for less than an hour to sit at rear part of the car and watch an event, battery was completely drained and we had to call road side service to restart the car. My car is available for inspection. How was your safety or the safety of others put at risk? Both of my cases did not caused safety issue. But it will be a serious safety issue if it happens at a remote location where there is no other car or cell phone signal to call for help. Our family do travel to remote location where there is no cell phone signal. Has the problem been reproduced or confirmed by a dealer or independent service center? I am very sure that problem can be reproduce by simply opening rear hatch for a while. When I took car to the dealer, the representative was aware of the issue but was not willing to provide free service to fix the issue because basic warranty was expired. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. It first happened when the car was about a year old (12,000 miles).
