Restricted Parts Delay Repairs, Forcing Mechanics to Waste Hours on Bureaucracy

John Zacek, a veteran technician in Wisconsin, encountered obstacles from Stellantis’ “restricted parts” policy while repairing a Ram pickup truck. Although he diagnosed a faulty fuel injector in cylinder three as the cause of a misfire—and believed simply replacing the part would resolve the issue—Stellantis’ warranty guidelines required him to first reset the fuel system, complete a 20-mile road test, and swap the suspect injector with the one in cylinder one to confirm the fault location before authorizing a replacement. The entire process took over four hours, yet the warranty labor allowance covered only 1.3 hours, leaving the rest as unpaid work. Zacek said these cumbersome procedures not only delay repairs but also prolong vehicle downtime for customers—one owner of a 2025 Ram waited 44 days before the issue was resolved. Technicians widely complain that while the manufacturer’s STAR technical support system is intended to ensure repair accuracy, it sacrifices efficiency and exacerbates workforce attrition in the industry.
