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.
SF176AB
VEHICLES MANUFACTURED FROM 6/27/97 THROUGH 11/20/98 MAY HAVE CATERPILLAR 3126A/B ENGINE OIL DIPSTICK CALIBRATIONS THAT WERE INCORRECTLY SET. A MODIFICATION EXIST TO INSTALL AND CALIBRATE A NEW ENGINE OIL DIPSTICK AT THE NEXT SCHEDULED ENGINE OIL CHANGE. *TT
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.
