1. 1The GT3, GT3 RS and GT3 RS 4.0 kept the motorsport-derived Mezger flat-six (port-injected, dry-sump), NOT the DFI Carrera engine — the Mezger never had an IMS bearing and is prized for durability.
2. 2Center intake-air-distributor campaign (Porsche WC51, MY2011–2012 GT3/GT3 RS): a component inside the intake-air distributor can break loose and be ingested, risking engine damage; Porsche replaced the distributor with new gaskets, o-rings and seals — verify completion on any 997.2 GT3/GT3 RS.
3. 3Center-lock wheel-hub recall: certain 2010–2011 center-lock Turbo/GT cars (built May 2009–Sept 2010) could suffer premature hub wear that lets a wheel loosen — confirm the recall work was performed on any center-lock example.
4. 42010 GT3 rear-wheel-hub recall (NHTSA 12V558000), separate from the center-lock campaign: the rear wheel hubs could fail in hard use and the original service interval was too long to catch the wear; dealers replaced the rear hubs and shortened the interval — confirm on any 2010 GT3.
5. 5Seat-belt anchor-plate recall (NHTSA 11V409000): a short 2011 build run (incl. the 2011 Speedster and GT3 RS, and 2012 Carrera/Targa/Turbo cars) had undersized anchor-plate mounting holes that could keep the plate from rotating correctly; belts were inspected/replaced as needed.

• 11V2850002010-2011
  Center-lock wheel hubs on center-lock cars could wear prematurely and let a wheel loosen.
• 12V5580002010
  Rear wheel hubs on the 2010 GT3 could fail under hard use; the original service interval was too long to catch the wear (separate from the center-lock campaign).
• 11V4090002011-2012
  Seat-belt anchor plates with undersized mounting holes could keep the plate from rotating correctly, so a belt might not restrain properly.
