Owner's Warranty Responsibilities
As the vehicle owner or lessee, you are responsible for the
performance of the required maintenance listed in your Owner's
Guide. Aston Martin recommends that you retain all receipts
covering maintenance on your vehicle, but Aston Martin cannot deny
warranty coverage solely for the lack of receipts or for your failure to
check the performance of all scheduled maintenance.
You are responsible for presenting your vehicle to an Aston Martin
Dealer as soon as a problem exists. The warranty repairs should be
completed in a reasonable amount of time, not to exceed 30 days.
C.12
Aston Martin may deny warranty coverage if the vehicle or a part has
failed due to abuse, neglect, improper maintenance, or unapproved
modifications.

violations of the terms of this warranty, you may contact Aston Martin
