Disadvantages of the Jeep EXJ engine
A defective high-pressure fuel pump was swapped out for a new one in engines manufactured between 2019 and 2021.
This didn’t always work because parts of the pump were able to enter the fuel system.
To replace cracked EGR coolers, another recall campaign was conducted.
Additionally, sensitive turbo lag and oil cooler leaks are complained about on specialized forums.
