2019 PETERBILT 389 Problems & Complaints

- The steering arm on the driver side of the Dana D-Series axle that was installed from the Peterbilt factory on a new 2019 Peterbilt 389 that was purchased new by Acord Transportation, Inc. is what failed. The steering arm on the D-Series axle bolts to the steering knuckle with two bolts as opposed to being one solid cast piece as in other families of Dana axles - such as the E-Series. When backing into a parking space the two bolts holding the steering arm to the steering knuckle broke, causing the steering arm to come free from the steering knuckle - ultimately causing a catastrophic failure and a complete loss of steering. Peterbilt took the steering arm for inspection following the failure, but did not return it to us. - Had this incident occurred while traveling on a public roadway, the driver would have lost all ability to steer the commercial vehicle (which could potentially be weighing 80,000 lbs and transporting hazardous materials) and would have no control over where the unit went. It could have resulted in an auto or property collision - potentially causing multiple injuries or fatalities. - We know of another company that has had two failures identical to this one. Allegedly, Dana Spicer admitted to our Peterbilt dealer that they knew of 12 other failures such as this. - The truck that experienced the failure was taken to the dealership where it was purchased. It was repaired by retrofitting the axle to the E-Series components. As mentioned, they kept the steering arm/bolts that failed. - There was no warning, nor is there potential to be any warning. If this happens, it will happen immediately and all control of the vehicle by the driver will be lost. The bolts that failed appeared to have been corroding for a period of time prior to the failure. However, there is no way to visually inspect the condition of the bolts without removing several components on the tire/wheel, hub and brake assembly and completely removing the bolts.

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

I PURCHASED A 2019 PETERBILT TRUCK IN MAY OF 2018. THE FRONT LEFT STEER TIRE FAILED ON JUNE 18,2018 AT HIGHWAY SPEEDS. RAPID AIR PRESSURE LOSS, AND HAVING TO TAKE EMERGENCY EVASIVE ACTION. THE TIRE HAD ONLY 10,580 MILES. I CHOCKED IT UP TO THE POSSIBILITY OF A ROAD HAZARD, AND LEFT IT AT THAT. FAST FORWARD TO TODAY OCTOBER 11,2018. RIGHT SIDE STEER TIRE FAILED AT HIGHWAY SPEED. TRUCK NOW HAS 54,653 MILES ON IT. I WAS FORTUNATE ENOUGH TO KEEP THE TIRE TODAY AND IT STRUCK ME AS ODD THAT THE SIDEWALL ON ONE SIDE SEPARATED CLEANLY FROM THE TREAD. THE OTHER SIDE ALSO SEPARATED, BUT IT SHOWS SIGNS OF TEARING THE PLYS THAT I ASSUME ARE THERE TO STRENGTHEN THE JOINT BETWEEN THE FACE AND THE SIDEWALL OF THE TIRE. NEEDLESS TO SAY, COMMERCIAL VEHICLES LOSING STEER TIRES IS ONE OF THE MOST DANGEROUS SITUATIONS WE COULD ENCOUNTER. I AM WORKING ON REPAIRS AS I TYPE THIS COMPLAINT. I WILL BE REPLACING THE TIRE, WHEEL, AND A BRAKE LINE THAT BECAME KINKED DUE TO THE TIRE. *DT *TR
