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.

NHTSA's summary

Flash: Park Assist Enhancement This Bulletin involves updating the Park Assist Module (PAM) software. A customer may notice at low speed operation (below 7mph/11kph) a cluster display indicating an object is detected by the front park assist system. This will be indicated by the fourth (farthest) arc on the vehicle graphic on the cluster. This will typically occur on gravel or sloped surfaces, like an approach ramp. The system calibration is overly sensitive which is causing ground detection as an object in the far zone. Also a condition may happen where the park assist chime will sound continuously. On further inspection one or more of the following DTCs may be found: B128E-25-PTS SENSOR 1 - Signal Shape / Waveform Failure. B128F-25-PTS SENSOR 2 - Signal Shape / Waveform Failure. B1290-25-PTS SENSOR 3 - Signal Shape / Waveform Failure. B1291-25-PTS SENSOR 4 - Signal Shape / Waveform Failure. B1292-25-PTS SENSOR 5 - Signal Shape / Waveform Failure. B1293-25-PTS SENSOR 6 - Signal Shape / Waveform Failure. B1295-25-PTS SENSOR 8 - Signal Shape / Waveform Failure. B1296-25-PTS SENSOR 9 - Signal Shape / Waveform Failure. B1297-25-PTS SENSOR 10 - Signal Shape / Waveform Failure. B1298-25-PTS SENSOR 11 - Signal Shape / Waveform Failure.

9003704	2022-09-26. Service bulletin. 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.
