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.
CSR-3278
Altec Industries, Inc. has been notified by Ford Motor Company that a defect related to motor vehicle safety exists in certain 2020-2022 Model Year Super Duty and 2021-2022 Medium Truck vehicles equipped with 6.7L Diesel Engines that are equipped with certain Altec aerial devices or service bodies.
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.
