ADMINISTRATIVE / DEALER RESPONSIBILITIES
WARRANTY CLAIMS
Warranty claim expense is to be charged to Warranty. Claims are to be
submitted in the normal manner, making reference to Safety Recall 18511.
Section 7 of the Warranty Policy and Procedures Manual contains further
information related to the submission and processing of AFC / Recall claims.
As with all claim submissions, items acquired locally must be submitted in the
“Other Charges” tab. The cost of any bulk items (such as a bag of cable tie
straps, roll of wire, barrel of oil, or tube of silicone) should be prorated for the
cost of the individual pieces / amount used during each repair.

UNITED STATES AND POSSESSIONS
The National Traffic and Motor Vehicle Safety Act, as amended, provides that
each vehicle that is subject to a vehicle recall campaign must be adequately
repaired within a reasonable time after the owner has tendered it for repair. A
failure to adequately repair within 60 days after a tender of a vehicle is prima
facie evidence of failure to repair within a reasonable time. If the condition is not
adequately repaired within 60 days, the owner may be entitled to replacement
with an identical or reasonable equivalent vehicle at no charge, or to a refund of
the purchase price less a reasonable allowance for depreciation.
Dealers must correct all vehicles subject to this campaign at no charge to the
owner, regardless of mileage, age of vehicle, or ownership, from this time
forward.
