2019 Peterbilt 567

The Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE21-015) based on one Vehicle Owner Questionnaire (VOQ) and supporting fleet reports. The reports indicated that the subject quarter fenders were prone to cracking and/or separation.After a comprehensive review of the data related to the quarter fender failures on the subject vehicles, ODI did not identify the existence of a safety-related defect trend. Quarter fender failures resulted in a warranty claim rate less than one percent (<1%) of the total vehicle population. All separations, including those due to tread separations, road hazards, etc., accounted for less than point one percent (<0.1%) of the total vehicle population.ODI discovered that the minimum recommended gap between the top of the quarter fender and the bottom of the trailer was not known or being followed. The optional quarter fenders were supplied by Fontaine Spray Systems (FSS), who recommended a two inch (2) gap. ODI analyzed the claim data using a calculated gap. A calculated gap using the top of the quarter fender flap and assuming the trailer is level with the top of the fifth wheel hitch was necessary, as PACCAR doesn't know specifically what trailer a purchaser will couple to the tractor. It is safe to assume no trailers on the market extend below the upper fifth wheel plate, but many do provide additional clearance over the wheels where the quarter fenders are located. ODI determined that 94 percent of warranty claims and 84 percent of separations violated FSS' recommendation.ODI confirmed that the VOQ vehicle and the fleet report vehicles also violated FSS' recommended gap. In one fleet the gap was negative point three inches (-0.3).PACCAR has updated its vehicle specification process and issued a customer advisory notice to existing owners. In light of the low rate of reported failures and separations, further use of agency resources does not appear to be warranted. The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists. The agency reserves the right to take further action if warranted by the circumstances.

On May 1, 2020, the Office of Defects Investigation (ODI) opened PE20006 to investigate complaints of intermittent loss of power steering assist in Daimler Truck North America (DTNA), Volvo Trucks of North America (Volvo) and PACCAR vehicles equipped with a ZF/TRW (TRW) THP60 steering gear.  The investigation focused on 2010-2020 DTNA Freightliner Cascadia, M2 and WST; Volvo VN, VAH and VHD and PACCAR 337, 365, 389, 567, 579 model vehicles.Field reports and interviews with fleet drivers allege that high power steering fluid temperatures could result in internal seal and bearing failures causing pressure fluctuation, affecting left and right-hand turns.  The inability of the driver to steer the vehicle as intended can increase the risk of a crash and injury. ODI analyzed data provided by TRW, DTNA, Volvo, and PACCAR in response to individual information request letters.ODI found that most failures occurred within the first two years and/or 50,000 miles of service.  The claim rate decreased with time and miles in service and remained less than 0.5%. ODI normalized data from each of the manufacturers and determined that there was not a substantial difference in the failures.Additionally, TRW improved a seal in the steering gear in December 2015.Trucks built on or after 2016 (as 2017 and newer model years) show a decreasing trend of failures. In view of the overall low failure rate, the nature of early-life failure, and failure rate trending downward for model years 2017 and newer, this Preliminary Evaluation (PE) is closed.  The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The Agency reserves the right to take additional action if warranted by future circumstances.

OUR DRIVER WAS IN TOW WITH A VEHICLE WHEN HE STARTED EXPERIENCING ISSUES WITH SHIFTING BETWEEN GEARS, WE ADVISED HIM TO RETURN TO THE YARD TO SWAP TRUCKS AND COMPLETE THE CALL THIS WAS ON 3/23/2020. BEING SHORT HANDED DUE TO THE STAY AT HOME ORDER WE DOWNED THE TRUCK UNTIL WE HAD ENOUGH STAFFING TO DELIVER IT TO PETERBILT FOR INSPECTION AND REPAIRS WHICH TOOK PLACE ON 3/30/2020. WE RECEIVED A CALL FROM [XXX] @ COAST COUNTIES PETERBILT (SAN LEANDRO) ADVISING ME THAT MY TRUCK WAS 4 DAYS OVER THE ONE YEAR WARRANTY MARK WITH JUST 21,594 MILES ON THE TRUCK AND I PROVIDED ME WITH AN ESTIMATE TO CONTINUE WITH REPAIRS SEE WHAT WAS WRONG. I ADVISED BOTH [XXX] AND [XXX] (SERVICE MANAGER) THAT NHTSA ISSUED 2 RECALLS (18V-931) AND (18E-102) BOTH PERTAINING TO A FAILED CLUTCHES THAT WERE INSTALLED INTO ROUGHLY 35-75K TRUCKS WHICH INCLUDED MY CLUTCH WHICH MATCHED THE SERIAL NUMBER AFFECTED CLUTCH RANGE PROVIDED BY EATON AND NHTSA ON BOTH OF THE RECALLS NOTICES. I REACHED OUT TO PACCAR AND EATON WHICH BOTH AGREED TO COVER A PORTION OF THE REPAIRS LEAVING ME WITH ALMOST A 3K REPAIR BILL FOR A PART THAT WAS ON NATIONAL RECALL. COAST COUNTIES PETERBILT, PACCAR & EATON ACTED IN BAD FAITH BY DISMISSING BOTH RECALLS, FURTHER THEIR LACK OF QUALITY ASSURANCE RESULTED IN MY COMPANY SUSTAINING AN AVOIDABLE LOSS OF REVENUE INC TRUCK & INSURANCE PAYMENTS WE HAD TO MAKE FOR A TRUCK WE WERE NOT ABLE TO USE FOR OVER 3 WEEKS AND COULD HAVE RESULTED IN SOMEONE BEING SERIOUSLY HURT.
