A rear hatch or trunk warning indicates that the vehicle may not recognize the closure as secure. Cargo, an incompletely engaged latch, or a sensing concern can be relevant, but the display alone cannot distinguish them.
While parked, check for obstructions and use the normal closing procedure. Do not force a powered liftgate or drive with an unsecured rear closure. Follow the owner's manual for any operating restrictions.
If the warning persists after proper closure, contact A1 Auto 3 Brothers Car Repair. Note whether the rear interior light remains on or the power-opening function also behaves unexpectedly.
