Owners/service Manual problems of the 2015 Ford Escape

I have owned my 2015 Escape since March 2016. Beginning 6 weeks ago the car failed to recognize the Ford key. Had car towed. Told battery needed to be replaced. Replaced both car and key fob batteries. Within 7 days the car refused to start after sitting in the garage for 3 days. Had to get it towed and the battery recharged. Third time the car refused to start it had been driven and then left sitting for 5 days. Once again had to have a jump start. Took into dealership and told diagnostic info states no issues. Technician is unable to duplicate car refusing to recognize key fob or not starting. Explained that car once jumped started runs fine as long as I drive it day to day. Once it has been sitting for 2 or more days does it again refuse to start. Appears that something somewhere within the electrical system is pulling all the juice out of the battery regardless of what the onboard computer says. Second issue with this car has been the rear hatch. Technician inspected the rear hinges and said they are bent so when you close the hatch using the button on the hatch or key fob, hatch comes down but won't latch tight and goes back open. If you manually slam the hatch shut, the latch seemed to be tight however my hatch is not square anymore. It is tight to the passenger side but has a 1/4 gap on the right side which lets in air and water into the car. Told that I'd need to have a body shop take the hatch off and replace both hinges. This car has never had an accident nor has it been treated roughly so explain to me how the hatch got out of alignment to the point it is causing issues with shutting tightly? this seems to be a design flaw where the hinges installed are too light weight to stand up to normal wear and usage. Living in the upper midwest this car is exposed to winter weather including salt and road sand which in turn can get into open spaces and rust.
