Problem overview

Some Porsche 718 Cayman owners report experiencing unexpected trunk openings without activation from the fob or latch. This issue may stem from a faulty trunk latch, which can cause the trunk to open while driving. Additionally, key fob interference from other electronic devices has been noted as a potential trigger for this problem. Some owners have also accidentally pressed the interior trunk release button, leading to the trunk popping open unexpectedly. Furthermore, electrical system issues may contribute to this malfunction. It is advisable for owners experiencing these problems to have their vehicle inspected by a qualified mechanic or contact a Porsche dealership for assistance in diagnosing and resolving the issue.
