subarunet.com.
Background
On certain affected vehicles, the six (6) front exhaust pipe nuts at the cylinder heads may not have been
tightened sufficiently due to variations in production. As a result, these nuts may become loose during
use and cause exhaust leakage. A leak occurring at the front exhaust pipe may result in deterioration of
emission performance. As a result, affected vehicle may fail to meet emission levels certified by the EPA
and/or California ARB.
Description of the Remedy
Subaru retailers will inspect the 6 nuts securing the front exhaust pipe to the cylinder heads on all
affected vehicles. If any of the 6 nuts are found to be loose or lost and / or exhaust gas leakage is
identified at either of the connections to the cylinder heads, the retailer should replace the front
exhaust pipe.
Retailer Responsibility

retailer inventory necessary steps should be taken to ensure the recall correction has been made before
selling or releasing the vehicle.
