Component: SUSPENSION:FRONT:MACPHERSON STRUT

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 & Remedy

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.
