The 997.2 Turbo (2010-2013) is one of the most reliable 911 Turbos ever built, but the direct-injection 9A1 engine has documented IMS-free bore scoring issues, and the PDK transmission can develop cooler and mount failures that lead to expensive repairs if ignored.
Cylinder Bore Scoring / Premature Engine Wear
Occasional · high severity
Typical onset: 50,000-90,000 mi
Symptoms: Cold-start smoke or blue smoke on deceleration, Metallic ticking from engine bay that worsens when warm, Rising oil consumption (>1 qt per 1,000 mi), Loss of compression on bore scope / leak-down test
Fix: Complete engine rebuild or short-block replacement required; scored cylinders cannot be honed out on Nikasil linings. Machine shop work plus 40-60 labor hours for removal, rebuild, reinstall. Some engines need full replacement.
Estimated cost: $25,000-45,000
PDK Transmission Oil Cooler Failure
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Transmission fault warnings or limp mode, Harsh or delayed shifts when transmission is hot, Visible ATF leaks near front undertray, Overheating transmission temps on track or spirited driving
Fix: Replace leaking oil cooler and flush contaminated fluid; requires front undertray removal and sometimes radiator stack disassembly. 6-10 labor hours depending on access.
Estimated cost: $2,200-3,800
Transmission / Engine Mount Deterioration
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunking from rear on hard acceleration or deceleration, Excessive driveline vibration at idle in gear, Visible oil weeping from transmission mount area, Gear lever slop or misalignment
Fix: Replace failed hydraulic mounts; typically rear transmission mount goes first. Requires lifting powertrain slightly. 4-6 hours labor per mount.
Estimated cost: $1,200-2,400
Turbocharger Wastegate Rattle / Actuator Failure
Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Rattling noise from engine bay at idle or light throttle (sounds like marbles), Reduced boost pressure or limp mode under load, P0299 or P0234 fault codes (underboost / overboost), Turbo flutter or surge on throttle lift
Fix: Wastegate flapper arms wear and rattle; some units can be rebuilt, others need replacement turbos. Access requires removing heat shields and exhaust components. 8-14 hours labor depending on turbo replacement vs. actuator-only repair.
Estimated cost: $2,800-7,500
Front Strut Mount / Suspension Component Wear
Common · low severity
Typical onset: 60,000-90,000 mi
Symptoms: Clunking over bumps from front end, Steering feels vague or less centered, Visible play in strut tower bearings during inspection, Uneven tire wear on front tires
Fix: Replace strut mounts, control arm bushings, and ball joints as needed; alignment required after. 6-10 hours labor for comprehensive front suspension refresh.
Estimated cost: $2,000-3,500
Carbon Buildup on Intake Valves (DI Engine)
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Rough idle or misfires when cold, Loss of power / throttle response at higher RPMs, P0300-P0306 misfire codes, Failed emissions test due to incomplete monitors
Fix: Walnut-blast cleaning of intake valves requires intake manifold removal and access to valve ports. 8-12 hours labor; some shops use chemical cleaning with mixed results.
Estimated cost: $1,800-3,200
Owner tips
Check engine oil consumption religiously — more than 1 qt per 1,500 mi warrants a bore scope inspection before purchase
PDK transmission fluid should be changed every 40,000 mi despite Porsche's 'lifetime fill' claim — most cooler failures happen with old fluid
Drive the car hard during test drive and listen for turbo rattle at idle immediately after — cold starts can mask wastegate issues
Budget $3,000-5,000/year for maintenance and expect a major service (carbon cleaning, mounts, suspension) around 70,000-80,000 mi
Buy one with documented oil consumption records and recent PDK service — avoid high-mileage examples without proof of frequent fluid changes; bore scoring is the only deal-breaker issue here.

Ohlins USA, Inc (Ohlins) is recalling certain Front Struts, part number POS 5N20. These struts were sold as part of Ohlins strut kits part number POZ MN02, intended for installation on 1999-2005 Porsche 911 Carrera 4 and 4S (generation 996), and 2001-2006 Porsche 911 Turbo / Turbo S (generation 996) and kit part number POZ MN05, intended for installation on 2005-2012 Porsche 911 Carrera 4 and 4S (generation 997), and 2006-2013 Porsche 911 Turbo / Turbo S (generation 997). The pin of the strut may experience excessive stress during maximum steering, possibly resulting breakage of the pin.
Consequence: If the pin fails, it will cause separation of the strut from the vehicle, affecting vehicle control and increasing the risk of a crash.
Remedy: Ohlins will notify owners, and dealers will request the return of all unsold kits containing the subject part from dealer/distributor inventory for a full refund. All owners who purchased one of the kits (POZ MN02 or POZ MN05) will receive replacement front struts (POS 5N20 or POS 5N21 - These parts are interchangeable), along with new top mount interface solutions, free of charge. The recall began December 22, 2020. Owners may contact Ohlins customer service at 1-800-336-9029.
