PURPOSE
This bulletin provides directions for inspection and repair of affected vehicles' Crossmembers.

BACKGROUND
The inside and outside surfaces of the Front Crossmembers used on certain vehicles, if exposed
long term to snow melt water and anti-freezing agents, may corrode due to insufficient
performance of the rust protection. Should significant corrosion occur over time, a lower control
arm could eventually become detached resulting in loss of vehicle control and a potential collision.

AFFECTED VEHICLES
2008 – 2010 Lancer*
2009 - 2010 Lancer Sportback*
2008 -2013 Outlander*
2011 – 2016 Outlander Sport / RVR*
*Currently or ever registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine,
Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York,
Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin, and Washington D.C.

IMPORTANT
Affected new or used inventory vehicles must be repaired before the vehicle is delivered. Dealers
must check their inventory vehicles’ VINs on the Warranty Superscreen to verify whether the
vehicle is involved in this recall campaign. It is a violation of Federal law for a dealer to deliver a
new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered
by the notification under a sale or lease until the defect or noncompliance is remedied.

NOTE: If you encounter a vehicle which has excessive Crossmember corrosion, but is not covered
under this campaign (i.e., never registered in a salt belt state), contact your DPSM for further
directions.
