Disadvantages of the Jeep EXN engine
Leaks, particularly those involving the oil cooler, account for the majority of complaints on the specialized forums.
All of the hoses continue to leak, and the pipes are unreliable and frequently burst.
Bad fuel causes the erratic high-pressure fuel pump to malfunction and start driving chips.
In certain instances, the turbine overheated and failed as a result of a leaky corrugation.
The unit’s EGR system cooler and particulate filter are also weak points.
