Owner Complaints (1)
Your truck displayed a "Service Exhaust System" warning message within the first 2,000 miles and a check engine light shortly after. You've noticed a significant drop in fuel economy (from 18-19 mpg to 12-14 mpg), unusually high exhaust temperatures, and excessive fuel and DEF consumption. The dealer diagnosed a faulty Exhaust Gas Temperature (EGT) control module that needs replacement, but the part is restricted by Stellantis and must be ordered through a special process with no guaranteed timeline or communication updates. The repair will involve replacing the faulty EGT control module once the part arrives from Stellantis.
