Both times required a tow.

Check engine light came on (3rd time) dealer determined need new catalytic converter, at 9,300 miles on a new car. On back order.
Catalytic converter replaced
Smart module was installed with a pinched wire and finally gave out so the vehicle was running poorly.
The part that was replaced has failed again. A replacement part has been ordered. It is related to the fuel system and causes the engine light to come on and reduce gas mileage.
Wouldn't pass inspection due to computer faults within catalytic system. Put on new part and had to "break it in" and drive it several hundred miles before it would register on inspection system. Chrysler sent wrong part twice.
Diesel air mixture device. Still on warranty.
DEF system failure. Replaced DEF line + Injector.
Malfunction Indicator Light (MIL) came on. Took vehicle in for repair. Parts are on order (for over a month) have been driving with the light on for 1000+ miles. Dealer says that no damage will occur, Remote Start will not work now either

Warning message on dash read: "Exhaust filter 100 percent full. See dealer." Engine would not go into upper gears after message came on, with maximum RPM limited to 2,850 (limp home mode). Dealer fixed problem under warranty.
"Check Engine" light came on while vehicle being driven by my stepson. (He is very hard on cars. I was not in the vehicle with him.) I am taking the Grand Cherokee to the dealer today to have this problem checked out. Update: probably only reset light.
Oil leak on right side. Don't know yet what is leaking, but seems to be engine oil rather than ATF.
Engine light was on ... warranty work was done on the emissions system and a software upgrade was performed.

CEL light on, DEF problem
CEL light on again, DEF issue CEL light on again, DEF issue right after last repair
Exhaust filter plugged and made car undriveable.
P20EE code.Cat Converter TSB. Cat replaced under warranty.
Check engine light came on P20EE error. NOx out of range. Software updated. Emissions system cleaned. Light reset. It came back on in a couple of days. Needs new catalytic converter. This is a known problem. TSB has been issued.
Changed catalytic converter and DEF sensor
First of three issues with the check engine light.
Check engine light came on again (third time). This time they replaced the Diesel Emission Fluid pump.
Converter faulty. Sensor defective.def nozzle replaced. All were upgraded. Was covered under extended warranty with 100 dollar deductible.
Otherwise would of been 5400 dollars.
Very disappointed with these failures
Removed nox sensor rear. Had to clean it and apply anti seize to the thread.

Replacement of rear exhaust temperature sensor
Another bad sensor

Check engine light for P20EE Code definition is "SCR NOx Catalyst Efficiency below Threshold Bank 1". There was a TSB issued. The dealer reflashed the PCM to turn out the light.
MIL light came back on a week after previous repair. Same code P20EE. Dealer said the head gasket is leaking. Ordered part. Gasket came in but dealer broke catalytic converter while replacing gasket. Converter on back order. MIL returned with the same code. Took vehicle to a different Jeep dealer. Code P20EE indicated to replace SCR. New SCR installed. Vehicle finally fixed.
Check engine light came on with P0171 and P0174: lean fuel from 2 sensors. Everything checked out fine at delear and the indicator had to be reset. Computer thinks it was triggered because of hard braking while engine was still cold.
Continued P0171 and P0174 lean fuel codes. STAR system says 'improper auto-stick operation when engine cold'. But, I'm always breaking when cold, as I live on a hill. Dealer replaced MAP sensor. Problem not reproduced since then.

From the first week I owned the Car it smokes oil smoke upon startup. Dealer as completed an oil consumption test. Dealer has opened a STAR request to Chrysler direct for solutions. No reply yet.
Smokes when start up in my incline driveway. Dealer determined the oil pan needed replaced, then kept it for oil consumption test. All seemed OK....two weeks later more smoke. Dealer pulled head off engine and found crack in head gasket. Engine continued to emit smoke at start when Jeep parked in my driveway...slight incline. Took four times to the dealer and Chrysler Mechanic to find problem with oil leaking into manifold.
Oil pressure sensor failed. Reported max pressure causing engine light to come on and disabling the remote start.
Fuel vapor recirculation solenoid

MIL on. ODB2 scanner reports P0520 error: Engine Oil Pressure Sensor Circuit Found TSB 18-034-14 (known issue). Replacement part was ordered from previous visit. Installed and issue corrected.
Burning oil. Blue smoke from exhaust, and low oil levels between oil changes. Shop suspects that a software issue caused higher-than-necessary vacuum pressure and issue would be fixed with SW update. Have not noticed symptoms since.
Fault code indicating fuel pressure sensor out of range. Dealer replaced fuel pressure sensor. Unknown if this resolved the issue because of other issue with ABS and traction control.
Notified Chrysler Customer Service of unresolved issues. They finally got technical expert in contact with technician at dealership. After two days of troubleshooting, identified improper wiring connection in engine compartment. Resolved.
Oil pressure sender replaced.
Primary fuel pump died.
MIL illuminated due to bad oil pressure sensor/
Check Engine light on. EVAP emissions codes. Spring-loaded fuel filter seal was gunned up and not fully closing.

Emits blue smoke from exhaust on start up. Chrysler advised replacing PCV valve. Has reduced but not cured the problem.
Dealer diagnosed exhaust smoke as caused by leak of coolant into cylinders. Replaced both cylinder heads.
Loud noise heard during cold start-up. Delete replaced water pump but that was not the problem. Return trip for radios flush because dealer topped off with wrong coolant. Problem ended up being the belt tensioner

Smelled radiator coolant. Dealer did test and found leak. Replaced radiator core.
Check engine light on. Plus car will not stay in ECO mode when selected.

Engine service soon light. Diagnosis at the dealer indicated need to replace the thermostat, engine not warming up quick as it should have. Thermostat replaced under warrantyrnThey also reported need for alignment which I paid about $60 for
