On two different occasions while driving on the highway at 60 MPH to 70 MPH, the engine of the vehicle shut down completely, without warning, with the loss of all steering or control over the vehicle. On two other occasions, the engine shut down completely, without warning, with the loss of any steering or control over the vehicle, after exiting the highway and entering city traffic. That is a total of four engine shut downs or stalls while driving the vehicle. The dealer can find nothing wrong with the vehicle. We just bought the vehicle, and this is nerve-wrecking and dangerous to say the least. The engine shuts down after driving long distances, and has happened from driving distances of approximately 90 miles to 160 miles. If you wait approximately one hour, the vehicle will then start up again and run. But it will stall again with complete loss of power. …
6/9/2018 around 11:30 am engine - starts and stalls without warning. Was driving and slowed down to merge with traffic to enter the highway and engine shut down no warning. It started back up; however, the car behind me almost ran into the back of me - car behind me started blowing the horn continuously; although, flasher was turned on immediately. It occurred 3 more times within an hour - 2 times when attempting to park the vehicle and one time when on the highway and had to slow down as traffic came to a near halt. Very scary situation. About 5-6 months ago this occur about 5-6 times in heavy afternoon traffic due to an accident. Thought it was the gas; now I see it is occurring again. Has to be a bigger or more serious problem. Others are experiencing the same problem just look online. Can not afford to allow car to idle too long. …
3 times while driving on the saw mill parkway this morning in stop and go traffic, while coming to a stop the vehicle started to accelerate out of control. The brakes could not control it. The first time I put it in neutral and the engine reverted to idle speed and I was able to continue normally. A few miles later it did it again as I was coming to a stop in heavy traffic. This time when I put it in neutral the engine raced at full speed as if it was being floored. I had to turn off the key. When I restarted the engine it ran fine for a few miles until I was exiting the highway. Again when I slowed to a stop the engine raced at full revs. Going into neutral did not help. Turning off the key fixed it. At the end of the day after work the vehicle behaved normally. This Jeep has done this 3 times in the past, in January 2009, feb 2012 and October 2014.

Parked vehicle after driving 20 min. Going about 70mph. After turning the car off, the car started steaming. I popped the hood to find coolant and water overflowing from the coolant reservoir. I got the car towed to the local mechanic who after doing extensive diagnostics to find the leak within the system. Took the manifold off the engine and realized it was caused by bad/ cracked heads on the engine connecting to manifold. A lot of this type of engine has this problem, seen by the local auto mechanic in vail valley, colorado where jeeps are common. This is a manufacturer problem.
