Recall 12V329 covers 270 2011-2012 Porsche Cayenne and Panamera vehicles for turbocharger turbine-wheel fractures. Repair is free at any franchised Porsche dealer.
Porsche is recalling 270 2011-2012 Cayenne and Panamera vehicles because a casting defect can fracture the turbocharger turbine wheel and reduce performance. If the turbine shaft fractures, oil can enter the exhaust system, create smoke, and increase the risk of a fire; the Porsche dealer repair will be free once available.

What's wrong?
The turbocharger in these 2011-2012 Porsche Cayenne and Panamera vehicles helps the engine make power by using exhaust flow to spin a small turbine wheel. That spinning wheel helps force more air into the engine, which lets the engine burn fuel under pressure and respond when the driver asks for acceleration.
In this recall, the turbine wheel has a casting defect. Casting is the process that forms the metal part, and a defect in that metal leaves the wheel weaker than designed. If the turbine wheel fractures, engine performance drops. The damage also allows the turbine shaft to fracture, which further reduces power from the turbocharger.
There is no warning sign before failure. After the part breaks, the clearest clue is reduced vehicle performance, especially during acceleration.
Who's affected?
The Cayenne and Panamera listings share the same turbo/supercharger component across the included model years.
| 2012 Porsche Cayenne | Turbo/supercharger |
|---|---|
| 2012 Porsche Panamera | Turbo/supercharger |
| 2011 Porsche Panamera | Turbo/supercharger |
| Units affected | 270 |
A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
If the shaft fractures, oil can enter the exhaust system, causing smoke and increasing fire risk. If you see smoke or smell burning oil, pull over where it is safe and contact a Porsche dealer before continuing. Repair will be free at any franchised Porsche dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2012 Porsche Cayenne or Panamera is included in this recall.
- Contact a franchised Porsche dealer to ask whether the free turbocharger turbine-wheel replacement is open for your VIN.
- Reference recall number 12V329 when you call Porsche or the dealer.
- Bring the recall notice if Porsche mailed one to you.
- Avoid driving if the engine loses power or smokes. Ask the dealer about towing before moving the vehicle.
What happens at the repair
At the dealer, Porsche's listed remedy is for a Porsche technician to replace the turbocharger turbine wheels that are covered by recall 12V329. The work addresses the turbine wheel casting defect described for the 2011-2012 Cayenne and Panamera Turbo models. Parts and labor are covered by the recall once the dealer repair is available. Ask the service desk to confirm the VIN and the specific turbocharger work before the appointment.

Frequently asked questions
What is recall 12V329?
Recall 12V329 covers 270 2011-2012 Porsche Panamera and 2012 Porsche Cayenne vehicles with a turbocharger turbine wheel casting defect. If the turbine wheel fractures, performance drops and the turbine shaft can break, drawing oil into the exhaust and raising fire risk.
What should I do if my 2011-2012 Porsche Panamera or 2012 Porsche Cayenne is on this recall?
Check your VIN to confirm your specific Porsche is included in recall 12V329. If it is, contact a franchised Porsche dealer and ask for the turbocharger turbine wheel recall repair. Reference recall 12V329 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the covered defect at no cost, and Porsche's remedy says dealers will replace the turbine wheels free of charge. Parts and labor are covered at a franchised Porsche dealer.
What is the safety risk?
The safety risk is smoke and increased fire risk if the turbocharger shaft fractures. Oil can be drawn into the exhaust system after the turbine wheel fails. The recall does not include a do-not-drive instruction, but included vehicles still need the free dealer repair.
What if I bought my Porsche used?
The free recall repair still applies. Recall coverage follows the VIN, not the first owner. If you bought the vehicle used and never received Porsche's owner notice, check your VIN and reference recall 12V329 when you call a franchised Porsche dealer.
