# Service bulletin SSM 55237

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 2025\-2026 Mustang GTD vehicles built on or before 28\-Sep\-2026 may exhibit one or more of the following hydraulic system warning messages displayed in the instrument panel cluster \(IPC\): "Suspension Fault Speed Limited to 80 MPH", "Driver Selectable Suspension Fault", "Front Lift Not Available", "Drive Mode Not Available" and/or "Active Aero Fault". Diagnostic trouble codes \(DTC\) U0037, U0759, U075A, U075B, U075C, C0086, U0416, C1041, C1119, C1A03:A2, C1A04:A2, C1A05:A2, C1A06:A2, and/or P0EA7:19 may also be stored in the vehicle dynamics module \(VDM\) and/or powertrain control module \(PCM\). \<br/\>\<br/\> This condition may be caused by VDM software that incorrectly detects or reports a suspension or hydraulic system fault. To correct the condition, reprogram the VDM using the latest software level of the Ford Diagnosis and Repair System \(FDRS\). For claiming, use causal part 18B008 and labor operations 12651D and 12651D4.
