2003 Peterbilt 379 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

WHEN ENGAGED THE VEHICLE RAN FOR APPROXIMATELY 15-30 SECONDS THEN STALLED. THE CONSUMER THEN HAD TO MANUALLY UTILIZE THE "HAND PRIMER VALVE" IN ORDER TO RESTART THE VEHICLE. THE DEALER HAS ADVISED THAT SINCE DIAGNOSTIC TESTING EQUIPMENT DID NOT SHOWING ANY ISSUES, PROBLEM DID NOT EXIST. THE MOTOR WAS MANUFACTURED BY CATAPULT, SERIAL NO. 69Z70080. *NLM

I BOUGHT A 2003 PETERBILT 379 TRUCK WITH A SPLIT TANK IN NOVEMBER 2002. SINCE BRAND NEW THE TRUCK NEVER RAN RIGHT, EVEN THE OIL SAMPLES PERFORMED ON THE TRUCK SHOWED SOMETHING WAS NOT RIGHT. I TOOK IT BACK MANY TIMES TO THE DEALERSHIP ONLY TO BE TOLD NOTHING WAS WRONG. THE DEALERSHIP SENT ME TO THE CATERPILLAR DEALERSHIP BECAUSE IT WAS A CAT ENGINE, THEY SAID NOTHING WAS WRONG. AFTER SPENDING THOUSANDS OF DOLLARS IN HAVING MY TRUCK TOWED FROM PLACE TO PLACE AND BUYING PARTS TO TRY AND FIND THE PROBLEM MYSELF, I FOUND OUT THAT THE DIESEL FUEL IS MIXING IN THE HYDROLIC OIL. THE WHOLE TRUCK IS NOW CONTAMINATED AND IS BEYOND REPAIR. THE TRUCK IS UNSAFE TO DRIVE.
