Dear [Name],
At FCA US LLC, we recognize that the success of our business depends on the satisfaction of
our customers. We are constantly monitoring the quality of our products and looking for
opportunities to improve our vehicles even after they are sold. Because your long-term
satisfaction is important to us, we are contacting you on important improvements we would
like to make to your vehicle [1]. This will be done at no charge to you.
We are recommending the following improvements be performed on certain [2021 – 2022
Model Year (LA) Dodge Challenger (LD) Dodge Charger and (LX) Chrysler 300] vehicles.
WHY DOES MY VEHICLE NEED REPAIRS?
The rear axle pinion on your vehicle may not have been properly heat treated during the
manufacturing process resulting in low hardness. You may notice a loud noise coming from
the rear axle. This noise will become louder and, if ignored, can result in increasing vibration
while driving.
HOW DO I RESOLVE THIS CUSTOMER SATISFACTION NOTIFICATION?
FCA US will repair your vehicle free of charge (parts and labor). To do this, your dealer
will replace the rear axle assembly. The estimated repair time is about 2 hours. In
addition, your dealer will require your vehicle for proper check-in, preparation, and check-out
during your visit, which may require more time. Your time is important to us, so
we recommend that you schedule a service appointment to minimize your inconvenience.
Please bring this letter with you to your dealership.
TO SCHEDULE YOUR FREE REPAIR,
CALL YOUR CHRYSLER, DODGE, JEEP OR RAM DEALER TODAY

Once we receive and verify the required documents, reimbursement will be sent to you within
60 days. If you have had previous repairs performed and/or already received reimbursement,
