Unowned or seldom-used Porsche 996 models can develop a range of issues due to lack of regular operation. These can include deterioration of seals and gaskets leading to leaks, degradation of fluids like brake fluid and coolant, battery discharge and potential electrical problems, tire dry rot and flat-spotting, and fuel system issues such as clogged injectors or fuel pump failure. Additionally, rodent or insect infestations can occur in stagnant vehicles, causing damage to wiring, upholstery, and other components.
Addressing these potential issues proactively is crucial for preserving the vehicle’s value and ensuring its reliable operation when it is eventually used. Regular maintenance, even for stored vehicles, can mitigate many of these problems. Historically, the 996 generation of the Porsche 911 has faced scrutiny for certain inherent weaknesses, such as the intermediate shaft (IMS) bearing.
