Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

According to Ford Recall 25V726: "On your vehicle, it may be possible to experience a noisy, partially inoperable, or completely inoperable Heating Ventilating and Air Conditioning (HVAC) blower motor. An inoperable or partially inoperable HVAC blower motor may affect windshield defrost and defogging capability, which can decrease visibility under certain driving conditions, increasing the risk of a crash."

The Tire Pressure Monitoring System (TPMS), on some Ford E450 chassis may experience intermittent loss of signal at one of the wheels and display a fault on the information center of the dashboard . This fault should clear itself through normal driving but because of potential interference from the rear view camera system it is possible for the problem to re occur.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
