Concerns:

Information:

Connecting rods that were not manufactured according to specifications may have been installed in the engines of the affected vehicles. We cannot therefore rule out the possibility of the connecting rod bolts loosening over the service life of the vehicle.

If this happens, you may hear noises from the crank drive while driving and the oil pressure warning in the instrument would come on. If the customer continues to drive the vehicle, however, oil can start leaking from the engine, and engine damage cannot be ruled out.

 

Action required:

  • Replacing engine
  • Replace vehicle-specific stickers showing the allocation of vehicle identification number to engine number

 

Overview

On the affected vehicles, there is a possibility that connecting rods that were not manufactured according to specification are installed in the engine.

A potential defect in the surface of the connecting rod could lead to cracks, creating a loss of preload on the connecting rod screw connection.

Loosening of connecting rod screw connection while driving at high loads can lead to potential engine damage, stalling, loss of power and potential oil leakage from a damaged engine block.

PorscheeBay logo will replace the engine in the affected vehicles.

As parts arrive to your dealer, please arrange for this measure to be carried out
immediately on the affected vehicles.

 

What is the issue?

On the affected vehicles, there is a possibility that connecting rods that were not manufactured according to specification are installed in your vehicle. If threaded joints on the engine connecting rods loosen over time, you may hear unusual engine noise and the oil pressure warning in the instrument cluster could illuminate.  If the engine continues to be operated, severe engine damage, including potential for sudden loss of power, which increases the risk of a crash, or fire could occur.

 

What should you do?

The necessary parts to complete this recall are now available. Please contact any authorized PorscheeBay logo dealer to schedule an appointment to have this recall performed as soon as possible and to arrange for PorscheeBay logo-provided alternate transportation, if necessary.
