Owner Narrative

My 2018 Ford Transit 250 experienced a failure of the Input/Turbine Speed Sensor in the 6R80 transmission’s mechatronic lead frame at approximately 60,000 miles. The failure was confirmed by an authorized Ford service department, which retrieved DTC codes P0715-00 and P0717-00. These codes indicate that the turbine speed sensor signal is lost, forcing the transmission into limp mode, causing loss of power and erratic shifting. This is a serious safety concern, it can occur suddenly while driving and results in loss of proper gear control. Relation to Recall 19S07 Ford has already acknowledged this same defect in other vehicles using the 6R80 transmission. In Safety Recall 19S07, Ford recalled certain 2011–2013 F-150, Expedition, and Navigator models due to failure of the Output Shaft Speed (OSS) sensor in the 6R80 lead frame. The failure mode, symptoms, and remedy (lead frame replacement and PCM update) are identical. In my case, the failure is of the Input/Turbine Speed Sensor rather than the OSS sensor, but both are housed in the same lead frame assembly and both result in sudden sensor failure, limp mode, and unsafe driving conditions. Why Action Is Needed Despite the identical defect, Ford has refused coverage because my VIN is not included in Recall 19S07 and my vehicle is just outside the 5 year / 60,000 mile powertrain warranty. This exclusion leaves Transit owners unprotected even though we are experiencing the same premature failure Ford already acknowledged. Given the safety implications, I am requesting NHTSA to investigate whether Recall 19S07 should be expanded to include Ford Transit vehicles equipped with the 6R80 transmission. Summary Vehicle: 2018 Ford Transit 250, 60,000 miles DTCs: P0715-00, P0717-00 (Input/Turbine Speed Sensor failure) Component: 6R80 mechatronic lead frame (same part as in Recall 19S07) Symptoms: Limp mode, loss of shifting, unsafe drivability Ford refuses coverage despite identical failure acknowledged in other model
