"What are the reliability issues with the 991 turbo S?"

Question

Accepted Answer

Based on my research and owner reports, the 991 Turbo S (2012-2019) is generally quite reliable, but here are the key issues to watch for:

**Common Reliability Issues:**

**Engine & Turbo:**
- Ignition coil failures (relatively common, ~$50 each to replace)
- Turbo oil leaks, particularly on the right-side turbo/intercooler pipe
- Occasional boost leaks from vacuum lines
- Water pump failures leading to overheating

**Transmission:**
- PDK dual-clutch transmission can experience rough shifting or hesitation (usually resolved with software updates)

**Electrical:**
- Infotainment system glitches (freezing, connectivity issues)
- Battery drain issues if car sits for extended periods
- Window switch failures
- Mechanical valve failures (exhaust flaps, air vent flaps)

**Cooling System:**
- Front radiators prone to clogging from road debris
- Potential overheating issues if cooling system isn't maintained

**Minor Issues:**
- Frunk (front trunk) struts weakening over time
- Stone chips on rear fenders due to wide body design
- Uneven tire wear on sport suspension models

**Overall Assessment:**
The 991 Turbo S is considered quite reliable for a high-performance sports car. Most issues are minor and relatively inexpensive to fix. The car has proven to be robust with many owners reporting trouble-free operation even at higher mileages (40k+ miles). Regular maintenance is key to preventing problems.
