Effective immediately all repairs on involved vehicles are to be performed according to this notification. Service Action / Rapid Response Transmittal (RRT) #18-087 / Service Bulletin (TSB) #25-003-18 is no longer applicable for the involved vehicles only. Those vehicles that have already had this repair performed, as determined by our warranty records, have been excluded from this recall.
Remedy Available
| 2017-2018 | (RU) | Chrysler Pacifica PHEV |
NOTE: This recall applies only to the above vehicles equipped with Cruise Control (Sales Code NHM or NHZ) built from August 16, 2016 through August 07, 2018 (MDH 081623 through 080717).
| IMPORTANT: Some of the involved vehicles may be in dealer new vehicle inventory. Federal law requires you to complete this recall service on these vehicles before retail delivery. Dealers should also consider this requirement toapply to used vehicle inventory and should perform this recall on vehicles in forservice. Involved vehicles can be determined by using the VIP inquiry process. |
Subject
Some of the above vehicles may have received suspect Powertrain Control Module (PCM) software that was the remedy for Safety Recall U73 (18V-332). During some auto restart events (where the vehicle has been operating in PHEV propulsion mode, and the gas-fueled engine is attempting to restart in order to take over propulsion), the engine can synchronize 360-degrees out of phase. The detection of this missynchronization was not robust in the PCM software. In the PHEV propulsion system, the electric motor will continue to spin the engine in this condition causing significant amounts of unburned fuel to enter the catalyst and potentially ignite. A mis-synchronized engine could result in a loss of motive power, and/or a potential fire. A loss of motive power can cause a vehicle crash without prior warning. A fire can result in increased risk of occupant injury and injury to persons outside the vehicle.
Repair
Inspect for Diagnostic Trouble Codes (DTCs) P0420, P0430, P0016-19, P000A-D, P1B11, P0506, P219A or P219B. If codes present, perform the catalyst internal borescope inspection of their internal bricks (take photos) and inspect the surrounding components for signs of thermal distress. If DTCs P0420, P0430 are present, replace the catalytic converters and Oxygen Sensors (O2). All vehicles will require the software level of the PCM to be inspected and if an update is available, the PCM must be updated with the latest available software.
Alternate Transportation
Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if the vehicle must be held overnight.

- Starting with the front catalytic converter, unplug and then remove the two O2 sensors (Figure 2). Refer to the detailed service procedures available in DealerCONNECT> TechCONNECT under: Service Info>14 Fuel System/Fuel Injection, Gas/Sensor, Oxygen/Removal and Installation>Upstream.
NOTE: Number one O2 Sensor has a black plug, Number two O2 Sensor has a white plug. They must be replaced in the same hole they were removed from.
- Remove the rear O2 sensors. Refer to the detailed service procedures available in DealerCONNECT> TechCONNECT under: Service Info>14 Fuel System/Fuel Injection, Gas/Sensor, Oxygen/Removal and Installation>Downstream.
NOTE: Removal of some of the spark plug coils may be helpful to gain enough space to remove the rear number two O2 sensor. Refer to the detailed service procedures available in DealerCONNECT> TechCONNECT under: Service Info>08 Electrical/ 8I Ignition Control/Coil, Ignition/Removal and Installation.
Figure 2 – Front Catalyst and Oxygen Sensors
- The internal inspection involves removal of the two O2 sensors on each of the front and rear catalytic converters (Figure 3), and the use of a borescope inserted into the O2 sensor holes to capture images of the condition of the catalytic substrates (catalyst bricks) in multiple places including the condition of the interface of the substrate to the surrounding insulated mat.
Figure 3 – Front and Rear Catalytic converters
a. Start by inspecting the front converter first.
b. Insert the borescope into the hole that is closest to the cylinder head outlet (O2 Sensor Hole one).
c. Look at the condition of the substrate face (capture images when looking at an angle onto the substrate, not straight in line with the substrate holes, to allow for minor events such as chipping to be visible) (Fig. 4) and (Fig. 5).
d. Look for signs of discoloration, melting, chipping, degradation, or any other anomaly. Inspect the entire face. If there is evidence of overheating, the converters will need to be replaced, proceed to Step 1 of the Repair Procedure.
e. Look at the surrounding insulated mat (material at perimeter of substrate along catalyst wall). Mat should be in place between the catalyst brick and catalyst wall. It should not have holes or dropped lower than the catalyst brick material.
f. Look for signs of degradation, shifting (change of position; under the right conditions, it is possible for the upper catalyst substrate to be pushed down). If there is evidence of overheating, the converters will need to be replaced, proceed to Step 1 of the Repair Procedure.
g. Insert the borescope in the O2 sensor hole near the middle of the catalytic converter body. This location will allow access to view the exit side of the first substrate, as well as the entry side for the second substrate.
h. Up to this point all three accessible faces of the front catalytic converter should have been inspected. Reinstall the O2 sensors, ensuring they are placed back into the exact hole they were removed from. Ensure the O2 sensors are torqued to the proper specification 43 N·m (32 ft.lbs.).
i. Repeat from step Step b down for the rear converter inspection.
Figure 4 – Normal Substrate
Figure 5 – Extreme Damaged Substrate
NOTE: The damaged substrate will show primarily heavy damage (missing material/large holes). Lighter damage to the substrate will consist of broken matrix walls but may not have progressed to large sections of missing material /holes. If “chains” of broken cell walls are found, the catalysts & O2 sensors need to be replaced. This may be present from viewing at either O2 sensor location.
- If there are no signs of the catalytic converters having been overheated then perform the following:
- Reinstall the O2 sensors. Refer to the detailed service procedures available in DealerCONNECT> TechCONNECT under: Service Info>14 Fuel System/Fuel Injection, Gas/Sensor, Oxygen/Removal and Installation> Upstream>Downstream.

IMPORTANT SAFETY RECALL
Reprogram Powertrain Control Module
Dear [Name],
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
FCA has decided that a defect, which relates to motor vehicle safety, exists in certain [2017 and 2018 Model Year (RU) Chrysler Pacifica PHEV] vehicles.
It is extremely important to take steps now to repair your vehicle to ensure the safety of you and your passengers.
WHY DOES MY VEHICLE NEED REPAIRS?
The Powertrain Control Module (PCM) on your vehicle [1] may have received suspect software that was the remedy for Safety Recall U73 (18V-332). During some auto restart events (where the vehicle has been operating in PHEV propulsion mode, and the gas-fueled engine is attempting to restart in order to take over propulsion), the engine can synchronize 360-degrees out of phase. The detection of this mis-synchronization was not robust in the PCM software. In the PHEV propulsion system, the electric motor will continue to spin the engine in this condition causing significant amounts of unburned fuel to enter the catalyst and potentially ignite. A missynchronized engine could result in a loss of motive power, and/or a potential fire. A loss of motive power can cause a vehicle crash without prior warning. A fire can result in increased risk of occupant injury and injury to persons outside the vehicle.
HOW DO I RESOLVE THIS IMPORTANT SAFETY ISSUE?
FCA will repair your vehicle [2] free of charge (parts and labor). To do this, your dealer will update PCM software to detect and correct engine mis-synchronization and to inspect the catalytic converter and replace, if necessary. In addition, your dealer will require your vehicle for proper check-in, preparation, and check-out during your visit. Your time is important to us; please be aware that these steps may require more time. The estimated repair time is two to four hours. 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
CALIFORNIA RESIDENTS
The State of California requires the completion of emission recall repairs prior to vehicle registration renewal. Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the Emission Recall service is performed. Be sure to save this form since the California Department of Motor Vehicles may require that you supply it as proof that the Emission Recall has been performed.
In order to ensure your full protection under the emissions warranty provisions, it is recommended that you have your (vehicle or engine) serviced as soon as possible. Failure to do so could be determined as lack of proper maintenance of your (vehicle or engine).
WHAT IF I ALREADY PAID TO HAVE THIS REPAIR COMPLETED?
If you have already experienced this specific condition and have paid to have it repaired, you may visit www.fcarecallreimbursement.com to submit your reimbursement request online. [3] 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, you may still need to have the recall repair performed.
We apologize for any inconvenience, but are sincerely concerned about your safety. Thank you for your attention to this important matter.
