2015 Porsche Boxster problems
The Porsche Boxster and Cayman are mid-engine two-seater sports cars manufactured and marketed by German automobile manufacturer Porsche across four generations—as a two-door, two-seater roadster (Boxster) and a three-door, two-seater fastback coupé (Cayman).
The first generation Boxster was introduced in 1996; the second generation Boxster and the Cayman arrived in late 2005; and the third generation launched in 2012. Since the introduction of the fourth generation in 2016, the two models have been marketed as the Porsche 718 Boxster and Porsche 718 Cayman.
The nameplate Boxster is a portmanteau of boxer, a reference to its flat or boxer engine, and roadster, a reference to the body style. The nameplate Cayman is an alternative spelling of caiman, a member of the alligator family.

Common 2015 Porsche Boxster problems
The 2015 Porsche Boxster, like any other vehicle, has its share of common problems reported by owners. While the 2015 model is part of the third-generation Boxster, which is generally considered to be a reliable generation, there are still some issues that have been reported.
One common problem across various Porsche Boxster models, including the 2015 model, is a rear main seal oil leak. This issue appears as an oil leak from the bell housing joint between the engine and transmission. If not addressed promptly, it can destroy a clutch in a manual car and is a sign of other potential issues. The leak occurs due to wear in the piston rings and the liners of the cylinder, causing the piston to wobble and score the liner. The only solution is a replacement engine or rebuild and re-lining of the cylinders.
Another issue reported for the 2015 Porsche Boxster is a timing chain rattle and check engine light. This problem is common in older Boxster engines and is caused by a stretching of the timing chains and failure of the timing chain tensioner. The only solution is to replace the tensioner and the timing chains, which requires engine removal and the use of specialized timing tools.
Additionally, the 2015 Porsche Boxster may experience low or no battery power, especially if the car is not driven regularly. This can lead to the loss of battery power, which resets important systems and can cause unnecessary headaches. To prevent this issue, it is recommended to use a battery maintainer when storing or not driving the car for an extended period.
It is important to note that these issues are not exclusive to the 2015 Porsche Boxster and may be found in other model years as well. When considering the purchase of a used Porsche Boxster, it is essential to be aware of these common problems and to have any potential issues inspected by a qualified Porsche mechanic. Regular servicing and maintenance, especially at a Porsche dealership or recommended specialist firm, can help prevent these issues and ensure the longevity and reliability of the vehicle.

The 2013 Boxster still feels and smells new after over 6 years. The paint, Racing Yellow, has held up with only a yearly wax job. To keep it factory fresh, it's important to have yearly dealer service (oil changes) and a good car cover and garage. I would also advise bi-annual battery changes and brake fluid flush. But most importantly, just enjoy driving one of the best handling cars ever!

I've heard that the ultimate test of a car's cool factor is the way kids respond. Well, let me tell you, this car catches the eye of every kid I pass! The 2013 Boxster S is a phenomenal car. It's my first Porsche, and now I understand why those who own one appreciate it so much. It's incredibly fast, handles excellently, brakes superbly, and is just plain fun. The comfort is good, but not great - it's definitely not designed for long distances, and I wouldn't have it as a daily driver. Safety is excellent, but my only issue is with outward visibility. With the top down, it's okay, but with the top up, I almost need a ground guide. I marked down the value due to maintenance costs and purchase price. The price for a nicely loaded Boxster S is not cheap when you consider it's really a second car. However, I wouldn't hesitate to buy this car again and again. It's pure fun with the top down driving along Highway 1 or on a twisty mountain road!

Hi there! I hope you're doing well. I just wanted to say that I'm a huge fan of Porsches, and I think the Boxster is a really great car. I used to think they weren't very stylish, but the 2013 model is absolutely stunning in person! It's also one of the best handling cars out there. I will say that the base model doesn't have a ton of low end torque, so you'll want to keep the engine between 4500 and 7000 rpm's. But within that range, it's plenty fast! Of course, you do have to choose between power and mileage - you'll get around 18 mpg if you're pushing it, but you can get up to 30 mpg with a light foot. And the handling is just incredible - the car feels like it's glued to the road no matter how hard you push it. I used to have a Lotus Elise, which had amazing handling, but I think the new Boxster might be even better!

I recently traded my 13 Boxster S for a 2014 991. I always wanted a new body style and the 991 did not disappoint. However, I found that it was lacking in many areas where the 2015 Boxster S excels, such as ride comfort. The 991 made every crack in the road loudly and annoyingly noticeable. On the other hand, the Boxster's 6-speed transmission is a perfect fit for me, even at 6'2

I bought a new Boxster in 2014 from Checkered Flag in Va Bch. I test drove both the S and base models, thinking I would prefer the S, but I was mistaken. The base car does not have 'mediocre acceleration' as the Edmunds review suggests. It may be slightly slower than the S version, but it is more than adequate for normal use. In fact, it is faster than my 2006 Cayman S. I highly recommend the PDK transmission, which is a remarkable unit. Those who prefer a manual six-speed are missing out. In the past, I have owned several versions of the Cayman, an Audi TT RS, and a Corvette GS, but the Boxster is superior to all.
