Dear (Name):
This letter is to inform you that the warranty period on your vehicle’s 2.0L PHEV Engine has been extended to Unlimited years /
Unlimited miles from the completion of Safety Recall 78C. This warranty extension on the 2.0L PHEV Engine applies to certain [2024 2025 Jeep Wrangler (JL) and 2023 - 2025 Grand Cherokee/ Grand Cherokee L (WL)] vehicles. Our records show that you either own
or lease one of the vehicles affected by this warranty extension. However, after the point at which the 2.0L PHEV Engine Limited
Warranty expires by time and mileage, and this extended limited warranty takes effect, FCAeBay logo US reserves the option to limit the
maximum coverage amount to the total cost of replacement of the 2.0L PHEV Engine, or the cash value of the vehicle prior to the
illumination of the Diagnostic Trouble Codes (DTCs) identified below, whichever is less. The cash value of the Vehicle will be the
RETAIL VALUE as determined using the current NADA Used Car Pricing Guide, taking into consideration the location, mileage and
condition of the vehicle. If the NADA guide is not available, we will use any other nationally published vehicle valuation guide to
determine the RETAIL VALUE.
We are extending the warranty period on the 2.0L PHEV Engine because some of the vehicles within the above referenced
population are included in Safety Recall 78C and may experience an illuminated Malfunction Indicator Lamp (MIL) because of one
or more of the following Diagnostic Trouble Codes (DTCs):
• P2336 - Cylinder 1 Above Knock/combustion Vibration Sensor Threshold.
• P2337 - Cylinder 2 Above Knock/combustion Vibration Sensor Threshold.
• P2338 - Cylinder 3 Above Knock/combustion Vibration Sensor Threshold.
• P2339 - Cylinder 4 Above Knock/combustion Vibration Sensor Threshold.
One or more of the DTCs must be set, and your vehicle must be included in Safety Recall 78C, to be eligible for coverage. If you
are experiencing this condition now, or if you experience it in the future, simply contact your dealer to have the appropriate repair
performed. Conversely, if you do not experience this condition, then your 2.0L PHEV Engine is operating correctly and no
repair is necessary.
If you have already experienced this specific condition and previously paid for a repair, you may be eligible to receive a
reimbursement. Visit www.fcarecallreimbursement.com to submit an online reimbursement request. You may also complete the
enclosed Customer Reimbursement Claim Form and send your original receipts, invoices and/or repair order to the following
address for reimbursement. Your claim will be acted upon within 60 days of receipt:
