Common 2005 Porsche Boxster (987) problems

The Porsche Boxster (987) 2005 is known for several common problems that have been reported by owners. These issues can significantly impact the car's performance and reliability, and some of them can be quite expensive to repair. Here are the most common problems with the Porsche Boxster (987) 2005, based on the complaints from owners:

1. IMS Bearing Failure: The intermediate shaft (IMS) bearing is a common failure point in the Porsche Boxster (987) 2005. The IMS bearing is responsible for driving the camshafts, and if it fails, it can cause complete engine failure. This issue is more prevalent in earlier models, but it can still occur in later models. The cost of repairing this issue can be quite high, as it requires complete engine disassembly and replacement of the bearing.
2. Rear Main Seal (RMS) Leaks: The rear main seal (RMS) is another common failure point in the Porsche Boxster (987) 2005. The RMS is responsible for sealing the rear of the engine, and if it fails, it can cause an oil leak. This issue can be quite messy and can lead to engine damage if left unchecked. The cost of repairing this issue can also be quite high, as it requires engine disassembly and replacement of the seal.
3. Gearbox Cable Failure: The gearbox cables in the Porsche Boxster (987) 2005 are known to fail, which can cause issues with shifting gears. This issue is more prevalent in earlier models, but it can still occur in later models. The cost of repairing this issue can be quite high, as it requires replacement of the cables and adjustment of the gearbox.
4. Suspension Problems: Suspension problems are the second most common reason for a Boxster 987 to fail its MOT. Broken coil springs are the most common suspension issue, but other suspension components can also fail. The cost of repairing this issue can vary, depending on the extent of the damage and the components that need to be replaced.
5. Coolant Radiators and Air Conditioning Condensers: The design of the Boxster 987 means that the vents at the front of the car can become blocked with biomass, which can cause issues with the coolant radiators and air conditioning condensers. If left unchecked, this issue can lead to engine overheating and damage to the air conditioning system. The cost of repairing this issue can vary, depending on the extent of the damage and the components that need to be replaced.
6. Brittle Parts: Some owners of the Porsche Boxster (987) 2005 have reported issues with brittle parts, including the IMS bearing, gearbox cables, and cheap plastics used in the cabin. These issues can affect the car's reliability and can be quite expensive to repair.
7. Lack of Phone Connectivity: The Porsche Boxster (987) 2005 is an older car, and it does not have the same level of phone connectivity as newer cars. This can be a problem for some owners, especially those who rely on their phones for navigation and entertainment.
8. Unreliability: The Porsche Boxster (987) 2005 is known for its unreliability, particularly in earlier models. The IMS bearing and gearbox cables are both massive weak links for this car, and they can cause significant issues if they fail.
9. Boxster's Reputation: The Porsche Boxster has a reputation for being a "gym car" or not a "man's car," which can affect its perceived value and desirability.
10. Lack of Project Car Appeal: The Porsche Boxster is known for its reliability and ease of use, which can be a problem for some owners who are looking for a project car to work on.

In conclusion, the Porsche Boxster (987) 2005 is known for several common problems that can affect its performance and reliability. Some of these issues, such as IMS bearing failure and RMS leaks, can be quite expensive to repair. Other issues, such as suspension problems and coolant radiator blockages, can also affect the car's performance and safety. It is important for potential buyers to be aware of these issues and to consider the cost of repairs before purchasing a Porsche Boxster (987) 2005.
