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.
SB-143
No defect in Hale Equipment. Advising Hale customers (emergency vehicle manufacturers) that the Ford F550 interlock does not work like the typical Fire Truck Chassis and remote throttle can lost for a number of reasons.
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.
