Service bulletins for the 2016 Jeep Grand Cherokee
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| 101232 | 2024-11-07. Service bulletin. POWER TRAIN. Plate - Planetary |
| S2309000013 | 2024-01-16. Service bulletin. POWER TRAIN. Verifying Camshaft Diagnosis |
| W41 | 2023-01-09. Service bulletin. POWER TRAIN. Customer Satisfaction Notification W41 Reprogram Powertrain Control Module |
| 9003704 | 2023-01-09. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN. Transmission Oil Pan, Heater (TMU), Tube or O-ring Applies to vehicles equipped with 8 speed transmissions only; if you have a leak that appears to be at the pan the use of proper leak detection is recommended. The fluid in the 8 speeds can be detected with a black light and there are aftermarket spray on leak detection materials to help ensure that the leak is properly diagnosed and not from another location such as cooler lines, heater tubes, or case porosity. Please note that the transmission pan gasket is available for many of the 8 speed applications FCA offers. Please review the available quick connect and transfer tube parts, as replacement of the TMU may not be required. If a TOC line connection is found to be the source, the quick connect may need replacement. If the leak source is coming from the connection of the TMU to the transmission, the transfer tube may need replacement. When parts are returned to the QEC the retaining clips (snap ring) for the quick disconnect fittings are missing. (This leaves a question as to whether the clips were missing from the assembly plant, or the technician removed them in order to make line removal easier.) Please return the clips with the transmission heater and note if they were not there to begin with. For any questions regarding transmission heater, contact FCA Redacted Content. If no response in 15 minutes, proceed with repair. |
| S1709000010 | 2023-01-09. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Customer complaints may include abnormal engine noise, rough idle, lack of power, misfire. Upon investigation, it may be found that there is excessive camshaft lobe wear/lifter wear (roller failure) on one or more cam lobes and that camshaft/lifter replacement is necessary. |
| 9003704 | 2022-10-31. Service bulletin. POWER TRAIN; ENGINE AND ENGINE COOLING. Trans Oil Pan, Heater Tube or O-ring, Heater Applies to vehicles equipped with 8 speed transmissions only; If you have a leak that appears to be at the pan the use of proper leak detection is recommended. The fluid in the 8 speeds can be detected with a black light and there are aftermarket spray on leak detection materials to help ensure that the leak is properly diagnosed and not from another location such as cooler lines, heater tubes, or case porosity. If you have a leak concern please note that the transmission pan gasket is available for many of the 8 speed applications FCA offers. See your parts specialist for the proper gasket for the repair. |

| T23 | 2022-10-24. Service bulletin. FUEL SYSTEM, GASOLINE; EXTERIOR LIGHTING; ELECTRICAL SYSTEM; POWER TRAIN. Customer Satisfaction Notification T23 ? EGR Valve Function The Powertrain Control Module (PCM) on about 415,000 of the above vehicles has software that may be operating the Exhaust Gas Recirculation valve (EGR) with an aggressive seating velocity. An aggressive seating velocity may damage the EGR valve. As a result this condition may illuminate the Malfunction Indicator Lamp (MIL) and display a P0404 code. The PCM must be reprogrammed on all involved vehicles. |

| 9004009 | 2022-09-26. Service bulletin. POWER TRAIN. Transmission Kit with Torque Converter 1. All Promaster (VF) 3.6L/62TE equipped vehicles. If the transmission bracket to the transmission case fasteners are removed during servicing, the fasteners (Part Number 06511385A$) are one-time usage. Vehicles built prior to 10/23/2015 requires Service Kit PN 68461214AA; includes Transmission Isolator PN 68264483AA, and Adaptation Bracket 68264479AA and Fastener Service Kit PN 68329056AA Vehicles built after on or after 10/23/2015 will require only the Fastener Service Kit PN 68329056AA. 2. All 3.6L/62TE equipped vehicles. If the vehicle you are repairing has a crack in the flex plate or failed pump bushing inspect and confirm that both (2) dowel pins are present in the engine block, which align the transmission center line to the crank shaft centerline and visually inspect the dowel alignment holes in the transmission case. If the holes are damaged or elongated the transmission should be replaced to prevent further damage to the transmission/flexplate or pump bushing due to the inability to properly align the engine to the transmission during the repair. 3. All 62TE equipped vehicles. If pump bushing is scored or damaged and the dowel pin alignment holes are ok, replace the pump assembly as opposed to complete transmission. 4. All 62TE equipped vehicles. If vehicle is jerking/slipping with MIL code(s) P0740 or P2764, check TCC Solenoid operation. If TCC Solenoid is ok, the codes are indicative of a torque converter failure. Replace the torque converter. |
