NHTSA Complaint #11309417 — 2019 PETERBILT 389

WE PURCHASED THIS TRUCK MARCH 4, 2018. SINCE THAT DATE A TOTAL OF THREE (3) PASSENGER QUARTER FENDERS HAVE "FALLEN OFF" THE TRUCK. THE LAST SET HAD LOCK TIGHT ON THE BOLT. IT IS ONLY INVOLVING THE PASSENGER SIDE. UNSURE IF THE BOLT BROKE OR JUST BACKED OUT. THE LAST ONE WHEN IT CAME OFF HIT OUR PRIMARY AIR LINE AND KINKED IT. LUCKY IT DIDN'T SEVER IT. ALSO WE HAVE HAD THREE (3) "COUNTRY" HORNS VIBRATE INTO PIECES. ALSO THE LAST HORN WAS ATTACHED WITH LOCK TIGHT TO PREVENT THE BUGLES FROM COMING OFF AS DIRECTED BY THE SUPPLIER. ALL THE BUGLES HAVE FALLEN OFF DUE TO THE EXCESSIVE VIBRATIONS OF THIS PARTICULAR MODEL YEAR. NEEDLESS TO SAY WE ARE TIRED OF REPLACING PARTS THAT VIBRATE OR BREAK OFF ON A NEW TRUCK!!!! THE FENDERS GO UNDER OUR DRIVES AND OUT THE BACK. FORTUNATELY NOBODY HAS BEEN INJURED DUE TO THE FLAW OF THIS PART. THE VEHICLE WAS IN MOTION IN ALL INSTANCES ON A HIGHWAY. VARIOUS DATES WITH THE LATEST INDICATED. THE AIR COMPRESSOR STARTED MAKING A STRANGE SOUND BEFORE IT EVENTUALLY FAILED. WE COULD NOT MAINTAIN AIR PRESSURE IN THE TANKS AND THE LOW PRESSURE LIGHT WOULD COME ON FORCING US TO PULL THE TRUCK OVER SO THE SPRING BRAKES WOULD NOT ENGAGE. WE'VE ALSO HAD AIR DRYER ISSUES AND THE BRAIDED FUEL LINE TO THE FUEL PUMP HAD WORN CHAFED AND WORN THROUGH DUE TO A ROUTING PROBLEM. WE WERE TOLD THAT THIS ALLOWED AIR INTO THE FUEL WHICH INCREASED REGENERATIONS MORE THAN NORMAL
