What Problems Does the 2021 Porsche 718 Cayman Have?

The 2021 Porsche 718 Cayman generally enjoys good reliability, but some issues have been reported. One area of concern involves the turbocharged four-cylinder engines (2.0L and 2.5L), where some owners have reported premature water pump failure or issues with the direct injection system, potentially leading to rough running or reduced performance. Oil leaks, particularly around the timing chain cover or rear main seal, can also occur, although this is more common on older models.

Regarding recalls, it's essential to check the NHTSA website for any active recalls specific to the 2021 model year. Historically, recalls on the 718 Cayman have addressed issues like potential fuel leaks or problems with the seat belt pretensioners.

Long-term reliability depends heavily on adherence to the recommended maintenance schedule. Porsche recommends regular oil changes, filter replacements, and inspections. Neglecting maintenance can exacerbate existing issues and lead to more significant problems down the road. Carbon buildup on the intake valves can be a concern, especially on the turbocharged engines, due to the direct injection system. Using high-quality fuel and performing occasional intake valve cleaning can help mitigate this issue. Some owners have reported issues with the PDK transmission, particularly related to shifting smoothness or occasional hesitations, though this is relatively rare. Overall, the 718 Cayman is generally considered reliable, but preventative maintenance is crucial to avoid potential problems.

How long will the 2021 Porsche 718 Cayman last?

With proper maintenance, a 2021 Porsche 718 Cayman can easily exceed 150,000 miles or more than 10 years of service. Many owners report trouble-free operation well beyond this point. The key to longevity is adherence to Porsche's recommended maintenance schedule, using high-quality fluids, and addressing any minor issues promptly. Potential long-term weaknesses can include wear and tear on suspension components, bushings, and the potential for increased oil consumption as the engine ages. The PDK transmission, while generally reliable, may require servicing over time. Proper care is crucial for long-term durability.

What Technology & Safety Features are Included?

The 2021 Porsche 718 Cayman features the Porsche Communication Management (PCM) system with a 7-inch touchscreen, offering navigation, Bluetooth connectivity, Apple CarPlay, and SiriusXM satellite radio. The base audio system is adequate, but Bose and Burmester surround sound systems are available as optional upgrades for audiophiles.

Driver-assistance features are relatively limited as standard, focusing more on the driving experience than autonomous capabilities. Standard features typically include parking sensors, but options like adaptive cruise control, lane change assist, and front and rear parking assist with a rearview camera are available at an extra cost. These optional systems enhance safety and convenience, but they are not standard equipment.

Safety features include anti-lock brakes, stability control, and multiple airbags. While the NHTSA and IIHS may not have specifically crash-tested the 2021 718 Cayman, Porsche vehicles generally perform well in crash tests due to their robust construction and advanced safety engineering. Euro NCAP ratings, if available, can offer further insights into its crash performance. Optional safety features, such as the aforementioned lane change assist, contribute to a safer driving experience. The lack of standard advanced driver-assistance systems reflects Porsche's focus on driver engagement and a more traditional sports car experience.

2021 Porsche 718 Cayman Prices and Market Value

The 2021 Porsche 718 Cayman had a starting MSRP of around $60,000, with higher trims like the GTS 4.0 and GT4 exceeding $100,000 when new. As of late 2024, used market prices range from approximately $50,000 to $90,000+, depending on the trim, mileage, condition, and options. Depreciation is relatively slow for the 718 Cayman, especially for well-maintained examples with desirable options. Factors affecting resale value include the car's condition, mileage, service history, original MSRP (due to options), and the overall demand for sports cars in the used market. The GT4 trim typically holds its value exceptionally well due to its limited production and high performance.

2021 Porsche 718 Cayman Cost of Ownership

The 2021 Porsche 718 Cayman is generally considered costly to own. Insurance premiums are higher than average due to its sports car classification. Fuel costs are moderate, but premium fuel is required. Maintenance, especially at a Porsche dealer, can be expensive. Repairs can also be costly due to specialized parts and labor. While the car itself is relatively reliable, the overall ownership costs are considerably higher than mainstream vehicles due to the brand's premium nature and performance-oriented components.

2021 Porsche 718 Cayman Insurance

Insurance for a 2021 Porsche 718 Cayman is moderately priced, reflecting its status as a Coupe with strong safety ratings and
reasonable repair costs.

How Does the 2021 Porsche 718 Cayman Compare to Other Coupe?

The 2021 Porsche 718 Cayman competes with cars like the Audi TTS, BMW M2, and Alpine A110. In terms of performance, the Cayman offers a precise and engaging driving experience, often considered superior to the Audi TTS but similar to the BMW M2. The Alpine A110 is lighter and more agile but lacks the Cayman's engine options.

Regarding features, the Cayman's infotainment can feel dated compared to the Audi TTS. The BMW M2 offers a more comprehensive suite of standard features. Reliability is generally good for the Cayman, on par with the Audi TTS but potentially better than the BMW M2, which can have more reported issues.

Price-wise, the Cayman is typically more expensive than the Audi TTS and competes closely with the BMW M2. The Alpine A110 sits in a similar price range. If driving engagement is paramount and budget allows, the Cayman is a top choice. For a more feature-rich experience at a slightly lower price, the BMW M2 is a good alternative. The Alpine A110 is a niche choice for those prioritizing lightweight agility above all else. The Toyota Supra (while technically a coupe) offers similar performance for a slightly lower price, but doesn't deliver the same level of Porsche refinement.

Final Verdict: Is the 2021 Porsche 718 Cayman a Good Coupe?

The 2021 Porsche 718 Cayman is ideal for driving enthusiasts who prioritize performance and handling above all else. It's worth buying if you appreciate a pure sports car experience and are willing to pay a premium for it. Purchasing used can offer significant savings, but a thorough inspection and service history review are crucial. The Cayman GTS 4.0 or GT4 trims are highly desirable for their naturally aspirated engines and enhanced performance, but the base and S models still offer a rewarding driving experience. Consider whether you need the extra features of competitors, but for driving thrills, the Cayman excels.

718 Cayman T

This car is me. Basic Porsche that has all the performance options included as Standard. Sport exhaust Sport Chrono Short shifter PASM suspension Torque Vectoring rear diff. You can't even buy some of these things as options on the S or GTS etc. It is no wasted money, It, is just what a Porsche should be "performance and nothing else." None of this power xyz option that cost an extra $5000 $10,000. If that's not for you then fine shop somewhere else. Lexus or Mercedes would love your money. Don't get me wrong you can buy a Porsche that not only cost a lot but also one that has thousands of dollars of options. But if you truly want to experience great performance, get a Cayman T or Carrera T and join the PCA, and register for DE "drivers education". There you can learn to drive one of these cars on a racetrack and learn the car and your own full capabilities.

I love my 718 Cayman GT4

My 718 Cayman GT4 is 27 months old and has 17,000 miles. I live in NE Ohio and drive it year round unless it too ugly outside. We have driven around home, to track days an trips up to three weeks at a time. Very comfortable, handling is great. I get 18 mpg around town and 25 mpg on trips. I also get lots of compliments. Great car!
