KENWORTH Complaints

TRACTOR ABS SYSTEM APPLIES THE BRAKES TO THE TRAILERS WHILE CORNERING CAUSING THE VEHICLE TO BECOME UNCONTROLLABLE. THIS USUALLY OCCURS WHILE ENTERING OR EXITING A HIGHWAY AT SPEEDS ABOVE 30 MPH. THE ABS SYSTEM LOCKS UP THE BRAKES UNTIL THE TRACTOR AND TRAILERS COME TO A COMPLETE STOP. THESE TRUCKS AND TRAILERS WEIGH APPROXIMATELY 155,000 LBS., AND LOSING CONTROL IS A SAFETY HAZARD FOR ANYONE ON THE ROAD. THESE TRUCKS ARE 2021 MODELS WITH BENDIX ABS SYSTEMS. THIS ISSUE HAS BEEN BROUGHT TO THE ATTENTION OF KENWORTH (THE VEHICLE MANUFACTURE) AND BENDIX (THE ABS SYSTEM MANUFACTURE). LITTLE HAS BEEN DONE TO RECTIFY THIS SAFETY ISSUE. THIS HAS BEEN HAPPENING SENSE THE TRACTORS WERE PUT INTO SERVICE APPROXIMATELY 8 MONTHS AGO. THERE IS NO WARNING BEFORE THE ABS SYSTEM LOCKS UP THE TRAILER BRAKES, AND THERE IS NOTHING THE DRIVER CAN DO TO CONTROL THE TRUCK WHILE THE BRAKES ARE LOCKED UP.

SEAT BELT CABLE BECOMES FRAYED AND BREAKS. WILL BREAK COMPLETELY IF IN AN ACCIDENT. WITH NOTHING HOLDING DRIVER IN DRIVER WILL BECOME INJURED AND POSSIBLY DEATH. REPLACE WITH A BETTER CONSTRUCTED DEVICE

UNIT HAD CLUTCH FAILURE FAILED TO DISENGAGE UNDER 18E-102, PER FEDERAL GUIDLINES IT FALLS UNDER THE CLUTCH RANGE OF AU1704192065 AND FALLS UNDER EATONS ORIGINAL CAMPAIGN RELEASE BUT THEY REVISED IT TO WHERE IT DOES NOT COVER THIS ONE BECUASE NOW THEY CHANGED THE RANGE TO AU1711 THRU AU1804 BUT WE ARE SEEING A LOT OF FAILURE BELOW AU1711, WHY DOES EATONS DOCUMENT NOT MATCH THE FEDERAL DOCUMENTS? AND WHY ARE WE SEEING THESE CLUTCH FAILURES ON TRUCKS THAT WERE REVISED AND SAID TO NOW BE GOOD, BUT THEY ARE FAILING IN THE SAME MANNER

UNIT DRIVING DOWN ROAD AND BRAKE CHAMBER FAILED CAUSING BRAKES TO SLOWLY APPLY WITHOUT OPERATOR BEING AWARE UNTIL SEEN SMOKE COMING FROM DRIVE AXLE BRAKES. THE LOW AIR PRESSURE LIGHT DID NOT ILLUMINATE, STAYED HIGH ENOUGH NOT TO ILLUMINATE A LOW AIR WARNING. 2 INDEPENDENT FIRE INSPECTIONS PROVED THIS WAS A HALDEX BRAKE CHAMBER FAILURE. THE CHAMBER WAS INSPECTED AND FOUND IT IS IN THE RANGE WHERE HALDEX HAD MANUFACTURING DEFECTS OF THE POWER COIL IN THE PARKING CHAMBER, HALDEX CONFIRMED THEY HAVE AN ISSUE WITH THE 3030 CHAMBER, AND NOT ISSUING A RECALL EVEN THOUGH PUBLIC SAFETY AS RISK. SPRING BRAKE BROKE AND PUNCTURED THE RUBBER DIAPHRAGM CAUSING THE DRIVER TO LOOSE CONTROL OF THE BRAKING SYSTEM AND CAUSING ANOTHER TOTAL LOSS OF TRUCK AND TRAILER. ENTIRE INTERSTATE HAD TO BE SHUTDOWN FOR A LONG PERIOD OF TIME. CAUSING MORE RISK TO PUBLIC SAFETY THE HALDEX CHAMBER HAS A FATAL DESIGN FLAW THAT HALDEX HAS ADMITTED TO AND CAN LEAD TO LOSS OF BRAKING AND BRAKE FIRES, CAUSING TIRE EXPLOSIONS AND CARGO EXPLOSIONS, WHEN THE SPRING COMPRESSES THE POWER COAT PROTECTIVE COATING IS DAMAGED AND CAUSES THE POWER SPRING TO RUST THIS RUST THEN CAUSES THE SPRING TO BRAKE AND PUNCTURE THE INTERNAL DIAPHRAM OF THE CHAMBER. HALDEX IS ALSO AWARE THAT THE METAL USED IN MAKING THE SPRING CANNOT HANDLE THE PRESSURE FORCED UPON IT WITHOUT BREAKING EITHER BY TOOLING CAUSING MARKS AND FATIGUE IN THE METAL ITSELF. NHTSA HAS ALSO DONE ITS TESTING AND CONFIRMED ALL OF THESE FINDING AS WELL.

I HAVE A HANKOOK TIRE , MODEL AM15+ WITH LABELING ON THE SIDEWALL "MADE IN CHINA" THE SIZE IS 385/65R22.5 THE DOT CODE ON THE TIRE : 1BB31 53H1 3218 THIS DOT CODE IS NOT CORRECT FOR THE ABOVE TIRE. DO YOU RECALL TIRES WITH AN INCORRECT DOT CODE?*DT*JB

AT HIGHWAY SPEEDS THE COLLISION MITIGATION SYSTEM WILL GO OFF FOR NO REASON CAUSING A SUDDEN HARD BRAKING. THIS SEEMS TO BE EXTREMELY DANGEROUS IF VEHICLE IS TRAVELING ON WET OR ICY ROADS, IN CLOSE QUARTER CONSTRUCTION ZONES OR IF VEHICLE HAPPENS TO BE IN A TURN. UNFORTUNATELY IF ANOTHER VEHICLE WAS FOLLOWING TOO CLOSE WOULD BE AN ACCIDENT, WHICH I HAVE HEARD HAS HAPPENED. I HAVE TAKEN TRUCK TO KENWORTH SERVICE TWICE AND THEY SAID THERE IS NOTHING THEY CAN DO. IT IS A REQUIRED SYSTEM AND ARE JUST VERY SENSITIVE. I SEE NOTHING GOOD ABOUT THIS SYSTEM. WHEN I COME UPON AN ACTUAL HAZARD IT DOESN'T GO OFF. IT IS STRESSFUL TO DRIVE AND WONDER AT ANY GIVEN TIME IF THE HARD BREAK AND LIGHTS ARE GOING TO GO OFF AND HOPE YOU ARE NOT AROUND OTHER VEHICLES THAT WOULD ALSO BE AFFECTED BY THIS UNEXPECTED STOPPING OF A 80000 POUND VEHICLE. HOPEFULLY DRIVERS WILL NOT FIND OUT WHAT WOULD HAPPEN OF THIS OCCURRED ON WET OR ICED ROADS.

ON SUNDAY, THE 22ND OF MARCH, I WAS TRAVELING SOUTH ON US HWY 45. THE SKY WAS CLEARING AND THE ROAD WAS DRY. I HAD MY CRUISE SET TO 65 MPH. AS I APPROACHED AN OVERPASS, THE DISTANCE SENSOR ON THE FRONT OF THE TRUCK MISTOOK THE SHADOW OF THE OVERPASS AS A STOPPED VEHICLE. WARNING LIGHTS AND BUZZERS WENT OFF AND THE VEHICLE DID A HARD BRAKE. LUCKILY, THERE WERE NO OTHER VEHICLES AROUND ME. I TOOK IT TO OUR SHOP AND THE SYSTEM WAS CLEANED. FOUR DAYS LATER, THE SENSOR MISTOOK AN OVERHEAD INTERSTATE SIGN FOR A STOPPED VEHICLE. AGAIN, THE WARNING LIGHTS AND BUZZERS AND A HARD BRAKE. KENWORTH TECHS WERE SENT OUT TO OUR SHOP TO MAKE REPAIRS. EVERY ONE OF OUR DRIVERS THAT I HAVE SPOKEN TO HAVE EXPERIENCED THE SAME THING MULTIPLE TIMES. THIS IS DANGEROUS. IF SOMEONE HAD BEEN FOLLOWING ME, THEY WOULD HAVE REAR-ENDED MY TRAILER.

APPARENTLY THERE IS A FAILURE OF THE FUEL PUMP IN MOST MODELS OF THIS CUMMINS ISX15 MOTOR, THA WHEN IT DOES FAIL, SHUTS THE TRUCK DOWN ON HIGHWAY, OR WORSE, LIK EIT DID TO ME....SEND METAL SHAVINGS INTO THE REST OF THE MOTOR DESTROYING THE MOTOR. THERE HAVE BEEN RECALLS FOR CERAMIC PLUNGERS, WHICH I DON'T HAVE...AND RECALLS ON MANY YEARS THIS MODEL WAS MANUFACTURED. I HAVE AN EXTENDED MAJOR COMPONENT WARRANTY THAT CUMMINS WILL NOT HONOR SINCE THE FUEL PUMP FAILURE IS NOT COVERED.....DEALER HAS WITNESSED MANY FAILURES OF THE FUEL PUMPS AND NOT ALWAYS COVERED...EVEN THOUGH REPAIR OR REPLACEMENT OF ENGINE IS IN EXCESS OF $20000 TO $35000 FOR A NEW REPLACEMENT. THIS NEEDS TO BE ADDRESSED WITH CUMMINS !!
