Typical transmission symptoms owners report

  • Owners describe a hesitation of several seconds when accelerating from a rolling stop or stop sign, followed by a sudden lurch forward.
  • Multiple reports describe the vehicle stalling unexpectedly when coming to a stop or when brakes are applied firmly, sometimes requiring the car to be shifted to park and restarted.
  • Some owners report the car briefly loses power and acts as if it is in neutral while accelerating on an incline, with no warning lights and no diagnostic codes found.
  • One owner reported the engine shutting off while downshifting between 15 and 35 mph, which also cut power steering and ABS brakes.
  • A separate report describes stalling combined with clutch and brake engagement while turning, causing the vehicle to drift toward the opposite lane.
  • Owners with the CVT automatic report repeated stalling at stops, describing it as a recurring and unresolved condition.

Transmission & Powertrain recalls for the 2010 Subaru Legacy

    Power train:manual transmission

    Subaru is recalling certain model year 2010 and 2011 outback and legacy passenger vehicles manufactured from april 28 through june 23, 2010. Due to a programming error, a lubrication hole within the 6-speed manual transmission was omitted.

    Risk: If the transmission gears are not properly lubricated, a groaning sound may begin to develop alerting the driver of a problem. If the sound is ignored and no action is taken, the gears will eventually break and this condition will lead to vehicle power loss, possibly resulting in a crash.

    Remedy: Subaru will notify owners and dealers will repair the vehicles by drilling an oil lubrication hole and, if necessary, replace the internal parts with new ones free of charge. The safety recall began on july 28, 2010. Owners may contact subaru at 1-800-782-2783.
