Subaru of America, Inc. (Subaru) has initiated a safety recall for certain 2021 model year Crosstrek
vehicles, certain 2022 model year Forester, and certain 2021-2023 model year Legacy and Outback
vehicles.
DESCRIPTION OF THE DEFECT AND SAFETY RISK:
The vehicles included in this recall may contain an inhibitor switch that was manufactured with an
insufficient weld between the switch stator and cover which may allow water intrusion.
Over time, moisture intrusion may cause the inhibitor switch to become inoperative. An inoperative
inhibitor switch may result in the backup lamps not illuminating when in reverse gear, the rear-view
monitor not displaying, the transmission gear select indicator in the instrument panel not being
displayed, or inability to start the engine.
REMEDY:
For all the potentially affected vehicles, Subaru dealers will replace the inhibitor switch with a new
one at no cost to the customer.
AFFECTED VEHICLES:
A total of 95,830 U.S. vehicles will be affected by this recall, as listed below. Not all vehicles in the
production range listed below are affected by this recall. Coverage must be confirmed by using the
Vehicle Coverage Inquiry function on subarunet.com prior to repair.

vehicles in their inventory prior to the vehicle being placed in service may be subject to civil
penalties of up to $26,315 per violation (i.e., for each vehicle), as provided in 49 CFR §578.6 and
will also be in breach of the Subaru Dealer Agreement.
Any vehicles listed in any recall/campaign that are in retailer stock must be:
•
Immediately identified.
•
Tagged or otherwise marked to prevent their delivery or use prior to repair.
•
Repaired in accordance with the repair procedures outlined in the Product Campaign Bulletin.
Retailers are to promptly perform the applicable service procedures, to correct all affected vehicles in
their inventory (used, demo & SSLP). Whenever a vehicle subject to this recall is taken into retailer
inventory necessary steps should be taken to ensure the recall correction has been made before selling
or releasing the vehicle.
