Not all vehicles in the production ranges listed above are affected by this recall. Coverage must be
confirmed by using the Vehicle Coverage Inquiry function on subarunet.com prior to repair.
In addition to the Vehicle Coverage Inquiry lookup function by VIN, retailers may view and download
their affected VIN list from subarunet.com/Recalls & Campaigns/Recall Affected VIN List.
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.
Service, Parts, and Claim Instructions
Remedy parts must be ordered through PRIME. Please refer to ‘Recalls & Campaigns/PRIME Max
Quantities’ on subarunet for the orderable quantities. For detailed service, parts, and claim information,
please refer to the WRG-21 Product Campaign Bulletin on STIS.
Retailer Responsibility
Please be advised that it is a violation of Federal law for a dealer to deliver a new motor vehicle
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:
▪
▪
▪
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
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
