The first issue is that my tailgate window randomly unlocks. I get this "rear access open" message everytime it happens. The second issue that my fuel gauge started reading inaccurately, saying fuel is low when I know it isn't. I definitely wanna get to the bottom of these issues, I would greatly appreciate some help on this.

 

Rear window may just be the fob going bad. Key pads on them wear out and replacement pads can be gotten cheap online.
Fuel gauge may be the sender going bad or a connection. Bad part is gas tank needs to dropped to access fuel pump module assy. or it's connector.
