UPDATES: WRG-21 Fuel Pump Impeller Failure Safety Recall
Subaru of America, Inc. (Subaru) is initiating a new safety recall for certain 2019-2020 model year
Ascent, 2018-2019 model year BRZ, 2018 model year Forester (turbo), 2018-2020 model year Impreza,
2018-2020 model year Legacy, 2018-2020 model year Outback, and 2018-2019 model year WRX vehicles
in which the fuel pump may become inoperative.
Description of the Defect and Safety Risk
The affected vehicles may be equipped with a low pressure fuel pump produced during a specific
timeframe that may include an impeller which has been manufactured with a lower density. Under
certain conditions, the lower density fuel pump impeller may deform and interfere with the body of the
fuel pump, potentially causing the low pressure fuel pump to become inoperative.
If the low pressure fuel pump becomes inoperative, the check engine warning light or malfunction
indicator light may illuminate, and/or the engine may run rough. In the worst case, an inoperative fuel
pump may result in the engine stalling without the ability to restart the vehicle, increasing the risk of a
crash.

covered by a recall under a sale or lease until the defect is remedied. Therefore, any Authorized Subaru
Retailer failing to perform the applicable service procedures to correct all affected vehicles in their
inventory prior to the vehicle being placed in service may be subject to civil penalties of up to $21,000
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:

Once the remedy kits specific to this recall are available, 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.
