Example complaints
Other or unknown: “The 5th wheel mount bolts on my company's 2010 and 2009 Mack trucks are stretching and becoming loose. I saw unit 10101 on sunday, 20 march 2011 on our yard ready to hook up. I had finished my shift and was walking past the unit when I reached out and turned the bolt by hand.”
NHTSA complaint #10392537, filed 2011-03, 150,000 milesBody and structure: “Mack has been selling over the road trucks with substandard bolts holding the 5th wheel to the frame. As a mechanic with abf, I am seeing trucks every day with 5th wheels that are loose. On 22 september 2010, I worked on unit #10222 at the little rock shop. This truck had only 4376 miles on it and I could turn the 5th wheel bolts with one hand using a 10 inch combination wrench. I tried to torque the bolts to specs, but they only stretched. I replaced the bolts with aftermarket bolts which tightened normally.”
