What Problems Does the 2007 Porsche 718 Cayman Have?

The 2007 Porsche 718 Cayman (referring to the 987.1 generation Cayman) has a reputation for strong engineering, but like any high-performance vehicle, it has specific areas that require attention or are known for issues:

  • IMS Bearing (Intermediate Shaft Bearing): While the 987.1 generation (2006-2008) utilized a larger, more robust, non-serviceable IMS bearing compared to the earlier 986 Boxster and 996 911, it remains a rare but catastrophic potential failure point for some owners. Failures are significantly less common than in earlier generations, but concern persists.
  • Bore Scoring: This is a more prominent and serious concern, particularly for the 3.4L M97 engine found in the Cayman S. It involves damage to the cylinder walls, leading to excessive oil consumption, misfires, and ultimately necessitating an expensive engine rebuild or replacement. It's often exacerbated by short trips, cold weather operation, and oiling deficiencies. A thorough pre-purchase inspection is vital for S models.
  • Rear Main Seal (RMS) Leaks: Fairly common, these leaks typically manifest as minor oil drips from the crankshaft's rear seal. While not usually catastrophic, they can be messy and require attention, often addressed during clutch replacement when the engine/transmission assembly is separated.
  • Coolant Expansion Tank: The plastic coolant expansion tank is prone to cracking and leaking over time due due to heat cycling and material degradation. This is a relatively common and not overly expensive replacement item.
  • Water Pump: The water pump is a known wear item, often requiring replacement in the 60,000 to 80,000-mile range. Failure can lead to overheating.
  • Air-Oil Separator (AOS): A failing AOS can cause excessive white or blue smoke from the exhaust, high oil consumption, and potentially a vacuum leak, impacting engine performance.
  • Ignition Coils: As these vehicles age, ignition coils can degrade and fail, leading to engine misfires and rough idling.
  • Suspension Components: Bushings, control arms, and shock absorbers are wear items that will eventually need replacement, especially on cars driven hard or on rough roads.
  • Recalls: For the 2007 model year Cayman (987.1), specific recalls have been issued, such as NHTSA Campaign Number 06V386000 concerning the luggage compartment lid potentially opening while driving, and NHTSA Campaign Number 07V078000 for power steering fluid leaks. It's always crucial to check a specific VIN for any open recalls.
  • Long-Term Reliability: Overall, the 987.1 Cayman is considered reliable for a high-performance sports car, provided it receives diligent and specialized maintenance. Preventative care and prompt attention to emerging issues are key to its longevity.

How long will the 2007 Porsche 718 Cayman last?

With meticulous maintenance and regular servicing, a 2007 Porsche 718 Cayman (987.1 generation) can be expected to achieve well over 150,000 miles, with many examples successfully reaching 200,000 miles or more. Its years of service can easily extend beyond 15-20 years if properly cared for. The core drivetrain and chassis are engineered for durability. However, long-term weaknesses over time include the aforementioned bore scoring issue in 3.4L S models, which can be catastrophic.
