Service bulletin SSM 50275

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

Some 2019-2021 Ranger vehicles may experience an uneven and/or excessive gap existing between the instrument panel (IP) topper and the center tray/upfitter switch assembly. This may be due to a lack of rigidity in the IP topper not allowing the tray/upfitter switch assembly to latch properly. The following foam block service kit (SPN: KB3Z-2104338-A) should be used to correct this condition. Follow the installation instructions included with the kit to install the foam blocks into the IP topper and repair the vehicle.

TSB 20-2374	2020-11-05. Service bulletin. Some 2019-2020 Ranger vehicles may exhibit random Trailer Connected/Disconnected messages in the instrument panel cluster (IPC) message center when no trailer is connected. This may be caused by corrosion and/or moisture in C4098 (4-pin trailer tow connector), C4099(4/7 way trailer tow connector), and/or inline C405. To correct the condition, follow the Service Procedure steps to inspect and repair the wiring and reprogram the trailer module (TRM).
SSM 49264	2020-11-04. Service bulletin. Some 2019-2020 Ranger vehicles built on or before 30-Jul-2020 may experience poor and/or no temperature change when the temperature is adjusted in the climate control system. There may also be a clicking/snapping noise from behind the instrument panel. Diagnostic trouble code (DTC) B1082 and/or B1081 may also be retrieved from the front controls interface module (FCIM). This may be due to an issue with the blend door and its controls. To avoid repeat repairs, it is recommended to replace the climate control housing assembly (service base part# 18478). Refer to Workshop Manual, Section 412-00.
