Vehicle began displaying check engine light. Diagnostic code P219B (Bank 2 air-fuel ratio imbalance) was identified. Vehicle was serviced and a valve-related repair was performed. Shortly after, engine performance worsened and further inspection revealed metal shavings in engine oil and confirmed internal lifter/valvetrain failure. Oil levels were normal and maintenance records are available. No warning of low oil pressure or overheating occurred prior to failure. Independent service center and inspector confirmed internal mechanical failure. Engine failure created risk of sudden loss of power while driving. This appears consistent with documented Pentastar 3.6L valvetrain/lifter issues reported by other owners. Concern is potential for sudden engine malfunction and safety risk due to power loss.

What owners say
Jeep constantly leaks oil and overheats even after replacing the water pump, radiator and thermostat. The airbag light comes on randomly and also Navigation system no longer works.
The engine overheated due a coolant leak causing head gasket failure. The engine will now most likely need to be replaced. The engine is 3.0 ecodeiesel which was part of the FCA settlement . There were no warning signs. Engine overheated with dealership while getting the fuel tank pump replaced. Dealer confirmed issue.
Vehicle only has 38,000 miles and suddenly had visible oil leaking from underneath. No warning lights came on but I took to service center for inspection. The oil filter housing was found to be defective and "leaking badly". Technician informed me that because the component is plastic vs. metal it is a known defect in my vehicle make/model. I also confirmed many complaints of same issue in online forums. I contacted manufacturer but since vehicle is out of warranty they would not assist. Service provider stated the issue is of significant safety risk as engine could lose all oil, overheat, and become undriveable. Cost to repair=$1800
The contact owns a 2015 Jeep Grand Cherokee. The contact stated that while getting a routine oil change shortly after, the warning light for a throttle box illuminated. The contact stated that in the past after getting the same oil change, the warning light for the tire pressure sensor light was illuminated. The contact took the vehicle to the dealer who determined no failure indicated for the tires. The contact stated that every time they brought the vehicle in for inspection no failure was indicated despite the contact filling the tires with air. The contact stated that while driving on the freeway when they were attempting to drive the speed limit of 65 mph their vehicle could not accelerate beyond being between 45-50 mph. The contact was able to pull off the ramp where the vehicle eventually came to a seize. The vehicle began to smoke on the front end. The vehicle never turned into a full-blown fire however it did remain extremely overheated for a total of about 2 days. There were no injuries or medical attention needed. There was no police report. The vehicle was towed to the dealer. The vehicle was diagnosed that the head gasket had blown and the engine had melted. The vehicle had not been repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 117,000.
Driving down road the vehicle lost power and the vehicle stalled customer stated the heater light came on also,customer states the AC wasnt working at the same time vehicle towed home. Tried to add water the to vehicle put noticed it was leaking customer had vehicle towed to dealership tech perform diag and inspection found coolant leak coming from heater hose also perform block test fail rec. Teardown cyl heads for inspection
Engine coolant leak. Had to replace the turbo water feed tube located under the intake manifold. The tube has approximate 3" rubber line which is exposed to high temperatures and over time fails, requiring replacement. Repair cost of $1101.72. After replacing the hose and completing the repair, I still had a coolant leak. This time it appeared to be the water pump. I went to the dealer to get the purchase the pump and there was a mechanic note stating to check the water pump seals as it is known to have a pinched seal which causes leakage. To replace the seals, the mechanic has to remove the intake manifold and the covers in front of the water pump before the pump can be removed (labor intensive). Up until I had the vo8 recall I did not experience any problems. I also recently had a service def system alert. When I spoke with the mechanic he stated are you having coolant leakage and I said yes. The mechanic said it sounds like your turbo is about to fail. This is when I identified there is a vo1 recall.
Ive had this car in the shop 4 or 5 times for extreme overheating costed me 4500 so far and never fixed
