Porsche Boxster (987)
2005–2011
Data Availability
Milemark has classified only 11 NHTSA complaints for the 2005–2011 Porsche Boxster (987). This is not evidence of reliability — it likely reflects lower sales volume and owners reporting issues through dealerships rather than NHTSA. We cannot draw statistical conclusions from this sample size, so this profile focuses on what is documented.
What We Know From Recalls
No recalls appear on record for this generation, which suggests no federally mandated safety campaigns to date.
Warranty Extensions and Technical Bulletins
Porsche issued 378 technical service bulletins for the 987 Boxster — a high count that indicates known engineering corrections. TSBs often address recurring issues like IMS bearing failures, coolant pipe leaks, and RMS (rear main seal) oil seepage, but without classified complaint data we cannot quantify how often these affect owners.
Owner Watch-Outs
The limited complaints show clutch-related issues (6 reports, median 24,181 miles) and engine internals (2 reports). These align with known 987 concerns but sample size prevents pattern confirmation.
How to Research Further
A pre-purchase inspection by a Porsche specialist is essential. Check model-specific forums (Rennlist, Planet-9) for common failure modes. Pull a VIN history to verify maintenance records, particularly IMS bearing replacement and oil change intervals.
Trends
Complaint trends by era
← All yearsClick a window below to see complaint data scoped to just those years.
2005–2009 models account for the most complaints on record — 73% of 11 classified.
Year-over-year complaint volume
Complaints filed per individual model year, not blended into 5-year bands like the chart above — hover a bar for exact numbers. Recent model years show fewer complaints mainly because they've been on the road less time.
5-year windows, not manufacturer generations — this database doesn't have reliable platform/redesign data to draw real generation boundaries from. Recent model years show fewer complaints mainly because they have been on the road less time, not necessarily because they're more reliable — read this as complaint volume and mix by era, not a reliability trend.

From owner-filed complaints to NHTSA, not independently verified. Federal mileage reporting on recent complaints is sparse — see methodology. Cost ranges are national estimates from book labor hours and parts pricing, not this vehicle's actual repair history — they don't account for your location or shop type.
