Premature Engine Malfunction and Failure

The 1999 Porsche Boxster’s engine problems can become severe and lead to total engine failure. These issues can also be linked to bad components, such as a failing intermediate shaft bearing, which commonly happens with the 2003 model. Some owners have expressed disappointment because it usually happens to fairly new Boxsters that have barely reached 10,000 miles. According to reports, the car may suddenly not start at all. However, some owners had to go through troublesome road incidents, such as losing engine power in the middle of the road. This may have caused harm or even death. 

Others have shared that their engine issues began with excessive hesitation, stalling, and idling. Some owners have reported taking their Boxsters to their dealerships, but mechanics were not able to exactly determine the cause due to the severity of engine damage. However, some owners have shared that engine-related repairs were covered by their warranties. Coverage may vary based on multiple factors, so make sure to confirm with your dealership first.

hi Everyone
I do have a Porsche Boxster 2007 Base modele, 6 cylinders
after 14 years and now 111000 miles I can only say that this car has been great and it is true that maintenance wise it is not cheap but who would buy an expensive car with a great engineering and expect low cost maintenance or not following the schedule ? with this one I never had any unexpected maintenance. I simply stick with the maintenance calendar and do the maintenance only at Porsche. this car is a commitment if you are not ready for that get something else.
As I said, maintenance always done at Porsche so if anyone has any question I can definitely answer.
have a nice day and fun


I have a 2006 with 160000 miles, only issues have been (i) convertible top pistons, (ii) emissions, AOS and MAF, not bad for such an elder car. Best car I have ever owned. My shop sees Boxsters with 300000 miles

I have a 2001 base model with just shy of 50000 miles. I love it 💕 The companies that beat them up for IMS bearings so they can promote their fix. I’m calling B.S. on that. Actually my 2001 has a failure rate of less then 3%. That vintage were all made in Finland and most have good bearings. My Boxster is fun,fun,fun to drive.
