Typical electrical symptoms owners report

Rear hatch or door 'ajar' warning light and chime activate falsely while the door is fully closed, often triggered by bumps, turns, or open windows/sunroof.
Interior dome lights stay illuminated or flicker on their own while driving, sometimes tied to the same door-ajar sensor fault.
Headlights and brake lights have stayed illuminated after the vehicle was parked and shut off, then turned back on unexpectedly.
Backup lights reported as extremely dim or non-functional, making it hard to see obstacles when reversing at night.
Owners describe the false door-ajar chime worsening over time, in some cases becoming a near-constant issue in warm weather.
