Everything below is an owner-reported complaint submitted to NHTSA about the 2018 Mack Mru, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
2018 MACK GRU WITH 40K HAS TWO CRACKED FRONT WHEELS MADE BY ALCOA. WE HAVE 10 OTHER TRUCKS 2012 TO 2019 WITH SAME WHEELS AND NO CRACKS. AFTER LITTLE RESEARCH ON THE INTERNET IT IS OBVIOUS MANY OTHER PEOPLE ARE HAVING THIS PROBLEM ON BUSES, RVS, AND TRUCKS. STRANGE WE WOULD HAVE 2 ON SAME TRUCK AND NO OTHERS. IT IS EASY TO ASSUME THE ALUMINUM ALLOY IS NOT RIGHT. VERY DANGEROUS!!!! PICTURES ATTACHED, YOU ARE WELCOME TO WHEELS, NOT LOOKING FOR ANYTHING, JUST GIVING INFORMATION
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
