The Porsche Cayman is famous for its balance, precise handling, and the joy it brings to drivers. Many car lovers dream of owning a Cayman at some point. But not every year is perfect. Some model years have well-known problems that can turn your dream into a headache. If you’re thinking about buying a used Cayman, it’s smart to know which years to avoid and why.
This guide will help you make a confident decision. You’ll learn about the Cayman’s history, the years with the most issues, what to watch out for, and how to spot a good deal. Even if you’re not a car expert, you’ll understand the main risks and get clear advice.
A Quick History Of The Porsche Cayman
The Porsche Cayman made its debut in 2005, filling the gap between the Boxster and the 911. It offered the mid-engine layout of the Boxster but with a coupe’s stiffer chassis. Over the years, the Cayman has gone through several generations, each bringing improvements in performance, safety, and comfort.
- First Generation (987): 2006–2012
- Second Generation (981): 2013–2016
- Third Generation (982/718): 2017–present
Each generation has its strengths. But some years, especially in the early period, have problems you can’t ignore. Let’s look at the details.
Why Certain Years Should Be Avoided
Not every model year has the same reliability. Some Caymans have engine issues, some have transmission problems, and others suffer from expensive repairs. Usually, the first years of a new generation are the riskiest. Car companies often use early buyers as “testers,” so bugs show up in the first few production runs.
Other reasons to avoid certain years:
- Known mechanical flaws that can ruin the engine
- High repair costs for common problems
- Poor resale value due to a bad reputation
- Safety recalls that affect many vehicles
Next, we’ll highlight the years you should think twice about.

Cayman Years With Major Problems
Choosing the right Cayman year is more than just picking a color or feature. Some years are famous for expensive engine failures and other headaches. Below you’ll find the main years to avoid and why they have a bad reputation.
2006–2008 Porsche Cayman (987.1)
The first-generation Cayman (often called 987.1) from 2006 to 2008 is one of the most discussed among car forums—and not always in a good way.
Common Problems
- Intermediate Shaft (IMS) Bearing Failure: This is the most feared issue. The IMS bearing can fail without warning, leading to catastrophic engine damage. Repairing this can cost over $10,000, and sometimes the engine is ruined beyond repair.
- Rear Main Seal (RMS) Leaks: Oil can leak from the rear main seal, causing messes and sometimes leading to larger engine problems if not caught early.
- Bore Scoring: Some engines develop deep scratches in the cylinder walls. This leads to oil consumption, smoke, and engine knocking.
How Common Are These Issues?
Not every car has these problems, but enough do that many mechanics warn against these years unless you have full service records or the issues have been fixed. The IMS problem, for example, is rare but so severe that even a small chance is risky.
Cost Of Repairs
- IMS bearing replacement: $2,000–$3,500 (preventative fix)
- Engine replacement: $10,000–$15,000
- RMS repair: $1,000–$2,000
Non-obvious Insight
Many people don’t realize you can check the engine number to see if it’s at risk for IMS failure, but even this is not a guarantee.
2009–2010 Porsche Cayman (987.2)
The 987. 2 models (2009–2012) fixed many early issues, but the first two years still had growing pains.
Common Problems
- Oil Leaks: Improved over 987.1, but some cars still have RMS or oil separator leaks.
- Electronics Glitches: Early 987.2 cars sometimes have problems with the PCM (Porsche Communication Management) system, leading to navigation and audio failures.
- Clutch Wear: Manual transmission cars have clutches that can wear out quickly if not driven carefully.
Why Avoid 2009–2010?
These years are better, but you still see more complaints about early engine wear and electrical gremlins compared to 2011–2012. If you want the most trouble-free 987 Cayman, later years are safer.
2017 Porsche 718 Cayman (982)
When Porsche switched to the new 718 Cayman in 2017, they introduced turbocharged four-cylinder engines. This was a big change from the older flat-six engines.
Common Problems
- Turbo Issues: Some early 718 Caymans had problems with turbo oil lines, which could leak and cause engine damage.
- Engine Hesitation: Owners report the engine feels “laggy” or has delayed throttle response, especially in the first year.
- Build Quality: There were more complaints about interior rattles and trim compared to later 718s.
Non-obvious Insight
Some mechanics note that early 718s had inconsistent engine software updates. Cars without the latest updates may run poorly or burn more fuel.
Years Generally Considered Safe
To be fair, not all Caymans are trouble. Some years have great reputations. The 2011–2012 Cayman (987.2) and 2018+ 718 Cayman are generally seen as safe, reliable bets. But even with these, regular maintenance is critical.
Detailed Breakdown Of Cayman Generations
Understanding what changed with each generation helps you spot the risky years. Here’s a comparison of the main Cayman generations:
| Generation | Years | Engine | Main Issues | Best Years |
|---|---|---|---|---|
| 987.1 | 2006–2008 | 2.7L/3.4L Flat-6 | IMS, RMS, Bore Scoring | None (all risky) |
| 987.2 | 2009–2012 | 2.9L/3.4L Flat-6 | Some RMS, PCM glitches | 2011–2012 |
| 981 | 2013–2016 | 2.7L/3.4L Flat-6 | Few known issues | All years good |
| 982/718 | 2017–present | 2.0L/2.5L Turbo Flat-4 | Turbo oil leaks (2017), software lag | 2018–present |
Why Ims Bearing Failure Is A Big Deal
The IMS bearing sits deep inside the engine. If it fails, the engine often seizes up and must be replaced. This problem is most common in the 2006–2008 Caymans. Even though the risk is low (often quoted as 1–8%), the cost of failure is so high that most buyers avoid these years unless the bearing has been upgraded.
Signs of IMS Issues:
- Metallic rattling from the engine
- Oil leaks with metal flakes
- Engine warning lights
IMS upgrades are possible, but unless a receipt proves it was done, assume the risk is still there.
Bore Scoring: The Silent Engine Killer
Bore scoring means scratches inside the engine cylinder walls. This issue mostly affects the same years as IMS failure but can sometimes appear in later 987s too. The first symptoms are increased oil use and a ticking noise on cold starts.
If left alone, bore scoring can destroy the engine. Repairs often require a full engine rebuild.

Common Cayman Problems Across All Years
Some issues happen on many Caymans, not just the “bad” years. These won’t always ruin the car, but they can add up.
- Coolant leaks: Hoses and radiators can develop leaks with age.
- Air-Oil Separator (AOS) failure: Causes smoke on startup and oil consumption.
- Clutch/dual-mass flywheel wear: Manual cars sometimes need new clutches before 60,000 miles.
- Suspension bushings: Worn bushings lead to clunks and poor handling.
- PCM (infotainment) failures: Especially in 987 and early 981s.
Most of these are not deal-breakers, but they do add to maintenance costs.
Cost Comparison: Good Year Vs. Bad Year
To see why the year matters, let’s compare the expected costs of a “safe” vs. “risky” Cayman.
| Year/Model | Purchase Price (Used) | Major Repairs (Avg.) | Total Cost After 3 Years |
|---|---|---|---|
| 2007 Cayman (987.1) | $22,000 | $7,000 (IMS, RMS, clutch) | $29,000 |
| 2014 Cayman (981) | $36,000 | $2,500 (minor issues) | $38,500 |
| 2018 718 Cayman | $50,000 | $2,000 (turbo, software updates) | $52,000 |
A “bargain” Cayman from a risky year can end up costing more than a newer, safer one. Always budget for possible repairs.
What To Check Before Buying Any Used Cayman
If you still want a Cayman from a riskier year, or you find a great deal, here’s what you MUST do before buying:
- Get a Pre-Purchase Inspection (PPI): Always have a Porsche specialist inspect the car. They can check for IMS risk, bore scoring, leaks, and accident damage.
- Review Service History: Full records are key. Look for proof of IMS upgrade, regular oil changes, and major repairs.
- Test for Engine Noise/Oil Use: Listen for ticking or knocking. Check for blue smoke on startup.
- Inspect Tires and Suspension: Worn tires or bushings can mean expensive repairs soon.
- Check Electronics: Test all buttons, screens, and lights.
A good PPI costs $300–$500 but can save thousands.
Real-world Owner Experiences
Many Cayman owners love their cars, but forums and review sites are full of warnings about the early years. For example:
- One owner bought a 2007 Cayman S with only 45,000 miles. Three months later, the IMS failed, and the engine had to be replaced—costing $13,000.
- Another driver picked a 2014 Cayman, and after 50,000 miles, only minor issues like a window regulator and worn tires appeared.
- A 2017 718 Cayman owner dealt with turbo lag and a check engine light, but a software update fixed both.
These stories show that while some risks are rare, they are not just “internet myths. ”
Should You Ever Buy A Risky Year?
Sometimes, a risky Cayman can be a smart buy—if the price is low enough and all known problems have been fixed. For example, a 2007 Cayman with a documented IMS upgrade, bore scoring checked, and a clean bill of health can be a bargain.
But if you’re not an expert, it’s safer to choose a later model.
How To Spot A Well-maintained Cayman
A good Cayman stands out with:
- Complete maintenance records
- No warning lights on the dash
- Smooth idle and no engine rattles
- Dry undercarriage (no leaks)
- Consistent power with no hesitation
If possible, buy from a Porsche specialist or a private owner who can explain the car’s history.
Cayman Vs. Boxster: Is The Risk The Same?
People often ask if the Boxster (the Cayman’s convertible twin) has the same risks. The answer is yes—the engines and most mechanical parts are the same in each generation. So, the years to avoid are the same for Boxster and Cayman.
How Porsche Addressed These Issues
Porsche listened to feedback and fixed many issues in later years. For example:
- IMS bearing: Redesigned in 2009+, almost never fails in 987.2 and newer.
- Bore scoring: Stronger engine materials in 981 and later.
- Electronics: Improved reliability in 981/982 with better wiring and PCM systems.
- Turbo oil leaks: Updated parts and software for 2018+ 718 models.
Non-obvious Insights For Buyers
- Check for Engine Software Updates: Many 718 Caymans run poorly without the latest updates. Dealers can check and update for free if the car is in warranty.
- Wider Tires Hide Issues: Some sellers put new, wide tires on to cover up suspension or alignment problems. Always have the alignment checked during a PPI.
Best Practices For A Reliable Cayman Experience
- Use high-quality oil and change it every 5,000 miles (not just once a year).
- Let the engine warm up before driving hard.
- Fix small leaks or noises quickly to prevent big problems.
- Join forums or local Porsche clubs for advice and trusted mechanics.

The Bottom Line: Which Years To Avoid
To summarize, avoid the following Cayman years unless they have documented upgrades and a perfect history:
- 2006–2008 (987.1): High risk of IMS, RMS, and bore scoring
- 2009–2010 (987.2): Fewer problems, but still more issues than 2011–2012
- 2017 (982/718): First-year turbo issues and software bugs
The 2011–2012 (987.2) and 2013–2016 (981) models are the safest used Caymans for most buyers. The 2018+ 718 Cayman is also a great choice if you want a newer car and don’t mind the sound of the four-cylinder engine.

Frequently Asked Questions
What Is Ims Bearing Failure And Why Is It So Serious?
IMS bearing failure is when the intermediate shaft bearing inside the engine breaks down. This can send metal pieces into the engine, causing total failure. Repairing it is very expensive, and it’s the main reason to avoid early Caymans without proof of an upgraded bearing.
Are All 987 Caymans Risky To Buy?
Not all 987 Caymans are bad, but 2006–2008 models have the highest risk. The 2009–2012 (987.2) cars fixed the IMS issue and are much safer, though 2011–2012 are the best years.
Is The 718 Cayman Less Reliable Than Older Caymans?
The 2017 718 Cayman had more problems, mostly with turbo oil leaks and software bugs. Later 718s (2018+) are more reliable. They don’t have IMS or bore scoring risks but need regular software updates.
How Can I Tell If A Cayman Has Had The Ims Bearing Upgrade?
Check the service history for receipts or notes about an IMS bearing replacement. Ask the seller for details. If there’s no proof, assume the upgrade was not done. A Porsche specialist can also inspect the car to confirm.
What’s The Best Year To Buy A Used Cayman?
The 2011–2012 Cayman (987.2) and 2013–2016 Cayman (981) are considered the best for reliability, performance, and value. They avoid the biggest engine risks and have better electronics.
Owning a Porsche Cayman can be a wonderful experience if you pick the right year and do your homework. Take your time, get a pre-purchase inspection, and choose wisely. The right Cayman will deliver years of driving pleasure with fewer surprises.
