UPDATE Safety Recall: WRE-22 Backup lamp switch failure
Owner Re-Notification
Affected vehicle owners were previously notified by first class mail on September 16, 2022. Subaru has
obtained updated owner registration information, and will re-notify affected vehicle owners who have
not yet had this safety recall performed, on January 11, 2024.
Subaru of America, Inc. (Subaru) is initiating a new safety recall for certain 2015-2021 model year WRX
STI vehicles, which may contain a defective backup lamp switch.
Description of the Defect and Safety Risk
The operating environment of the backup lamp switch may expose the internal switch contacts to
heated oil. When heated, sulfur in the oil may cause a chemical reaction with the materials used on the
switch terminal contact surfaces and plate spring. This chemical reaction may cause corrosion and a
non-conductive film to form on the contacts resulting in poor electrical conductivity.
Over time, the backup lamp switch may become inoperative which may result in the backup lamps not
illuminating when in reverse gear, the rear-view camera (if equipped) not displaying an image, and the
select lever/gear position indicator in the combination meter not displaying ‘R’ for reverse gear.
If the backup lamps do not illuminate when the vehicle is in reverse gear, this may reduce the awareness
of other motorists or road users of the driver's intention to operate the vehicle in reverse, increasing the
risk of a crash. Additionally, a rear-view camera (if equipped) that does not display an image can reduce
the driver’s view of what is behind the vehicle, increasing the risk of a crash.
Remedy
For all potentially affected vehicles, Subaru retailers will conduct an inspection and replace the backup
lamp switch with improved one, if necessary, at no cost to the customer.
