"The problem involves the double-clutch gearbox," NHTSA said in its recall summary. "In a situation of rapid vehicle deceleration, the transmission software may perform a multistage downshift. In that situation, at low vehicle speeds, it is possible for the engine to stall, increasing the risk of a crash.
BMW has rolled out its dual-clutch gearbox on all versions of the M3. For 2009, it's optional on the convertible, coupe and sedan.
The recall will start sometime in November. BMW dealers will reprogram the engine and transmission electronic control unit with updated software for free. M3 owners can contact BMW at (800) 831-1117.
Inside Line says: If you own one of the aforementioned M3s, better have it checked out ASAP with your dealer. — Anita Lienert, Correspondent
