2021 Porsche Cayman problems

Common 2021 Porsche Cayman problems

The Porsche Cayman, a highly desirable entry point to Porsche coupe ownership, is known for its superb handling and well-balanced design. However, like any vehicle, it is not immune to issues. Here are some common problems with the Porsche Cayman, specifically the 2021 model, based on complaints from owners:

• Engine Failures: The earliest Cayman models, including some 3.4-liter models, experienced engine problems, with oil starvation being the most common issue. Although Porsche introduced an upgrade in 2006 to protect the engine against similar issues, it is still advisable to be aware of these potential problems when considering a used Cayman.

• Oil Leaks: Degraded engine gaskets and oil leaks are common issues in older cars. Even used Caymans have experienced problems with rear oil seals starting to leak oil. This issue can lead to further complications, such as clutch damage in manual cars and potential signs of other issues, like spark plug seals and oil cooler seals.

• Rear Axle Carrier Side Fracture: In 2021, Porsche Cars North America had to recall several 2014 and 2015 model Caymans, Cayman S, and Cayman GTS vehicles due to the potential for rear-axle carrier side sections to fracture. This issue could lead to accidents, and while Porsche is replacing the affected parts for free, recalls can be stressful and time-consuming.

• CEL and Misfire at Higher RPM: Some users have reported engine misfires when the Cayman runs above 4,000 rpm, causing the engine to quit the cylinder. This issue does not seem to occur below 3,000 rpm, but it can still be a concern for those who enjoy driving at higher revs.

• Battery Management Problems: Porsche has had issues with battery management in the past, with 60% of all delivered Taycans experiencing battery issues that caused replacements, damages, and fires. While the Cayman is not as prone to these issues as the Taycan, it is still essential to be aware of potential battery complications and their associated costs.

When considering a Porsche Cayman, it is crucial to be aware of these potential issues and to have any prospective vehicle inspected by a local Porsche expert before making a purchase. A thorough pre-purchase inspection can help identify mechanical problems that may not be immediately apparent and ensure that the vehicle is in good condition.
