Common 2005 Porsche Boxster s problems

Based on complaints from owners of the Porsche Boxster S 2005, several common problems have been reported:

1. IMS-Bearing Issues: Owners have experienced problems with the intermediate shaft (IMS) bearing, leading to engine failure. This issue can be costly to repair and may result in complete engine failure if not addressed promptly. The IMS-bearing issue has been prevalent in models from the early 2000s, including the 2005 Boxster S. The solution typically involves replacing the IMS bearing to prevent catastrophic engine damage.
2. Electrical Problems: The 2005 Porsche Boxster S has been associated with electrical issues reported by some owners. These problems can manifest in various ways, affecting the car's performance and reliability. Electrical issues can be challenging to diagnose and repair, requiring thorough inspection by a qualified mechanic to identify the root cause and implement the necessary fixes.
3. Engine Casting Problems: Some reports have highlighted casting problems with engines in the 1999 model year and earlier Boxsters. These issues can lead to engine inefficiencies, performance issues, and potential safety concerns. To avoid these problems, it is advisable to consider purchasing a model year 2000 or newer Boxster to minimize the risk of encountering engine casting issues.
4. Transmission Recalls: A significant recall affecting 1999-2003 Boxsters involved addressing transmission issues to prevent inadvertent problems. While recalls do not necessarily mean a specific model year should be avoided, being aware of these safety concerns is crucial when considering purchasing a used Boxster. Understanding the history of recalls can help ensure that any safety-related issues have been addressed in the vehicle.

These common problems with the Porsche Boxster S 2005 highlight the importance of thorough inspection, regular maintenance, and awareness of potential issues when owning or considering purchasing this sports car. Addressing these problems promptly and proactively can help maintain the performance and reliability of the vehicle.

What goes wrong on Porsche Boxster S?

Porsche Boxsters have a number of common sources for leaking oil. Some of the most common include rear main seal (see below), valve covers, spark plug seals and oil cooler seals. Less common are leaks from the cam seals and scavenger oil pump seal.

What is the main problem with the Porsche Boxster?

The two main issues the Boxster and 996 faced at the start of the 2000s were IMS (intermediate shaft) bearing failures and RMS (rear main seal) issues. Contrary to popular belief, both of these issues, although certainly prelevant in both models, were not a guaranteed issue in models of this era.

Does the 2005 Boxster have IMS issues?

The single-row IMS bearing used in Porsche Boxster and Porsche 911 996 models from 2000-2005 reportedly had high failure rates of up to 10% under warranty, while the dual-row bearing had a lower rate. However, failure rates outside of warranty are suspected to be even higher.
