This Jeep engine failed / stalled while driving. This caused the vehicle to veer off the road twice on a turn, and almost cause two rear ends by failing in mid traffic, in four different occasions, since 2014. The vehicle engine cuts out, which causes the power steering and brakes to not function properly. The vehicle was in motion on various main streets, when this occurred. Naperville Jeep dealership (where this vehicle was purchased) has also maintained this vehicle per the maintenance schedule, has worked on this problem since it began. They have not been able to resolve the issue and returned the vehicle to us confident the problem was 'resolved' or non-existent. Attached is the vehicle recall and replacement record. From online research it seems this has occurred to other Jeep Grand Cherokee before and the typical solution is replacing the totally integrated power module (tipm). This vehicle's tipm was 'repaired' Sept 3, 2014. Below are the maintenance records related to this problem. 03/26/2014 mileage: 44,680 wro# 599705 11/25/2014 mileage: 51,329 cro# 615926 01/07/2016 mileage: 65,485 cro# 646292 06/10/2016 mileage: 69,938 cro# 658369 this vehicle is not safe and we have lost all trust and confidence in this vehicle.

Driving w on 60 in AZ, 30 mins after having oil changed at local auto care shop, where I was told everything looked fine but my radiator hoses looking soft. Consider getting G new ones in this 112 degree heat (like the day I'm submitting this). On freeway, engine overheats, stalls, steering locks, brakes harden and I come to a complete stop in an inconvenient 2 inches off the curb, still in everyone's way as they attempt to exit mill ave. Brakes hard and doesnt allow for push-to-start button to turn over. Nor to place in neutral. Standing by for a tow as we speak. Never had this happen before. Coolant just topped off three days ago and given an okay after oil change half hour prior to this happening. Perhaps coincidence. Perhaps just life. Reporting either way.

My car engine stalls when I make turns specially early in the morning for no reason it just stalls without warning but sometimes when I came to a stop light as well, very very unsafe & scary!!! I've been lucky usually in the lane close to the sidewalk so I can maneuver to the side but eventually my luck will run out, I'm very unease when I drive this vehicle as I don't when I'll happen. The tipm was already taken care of but I still have the problem is not all the time but it happens, I've taken it to the dealer right after it happens but they can not reproduce the problem or find any error codes

I was driving on the highway to work in the passing lane, when the RPM's went way up and then way down. I heard a loud noise coming from under the hood and loss of power from engine. No engine light indicator was on before this happened or any sort of indication this was about to occur. I pulled over and had it towed to the dealership. The dealership indicated that the crankshaft was broken internally and that this is a defect of workmanship as I can show records of every oil change on this vehicle. The dealership is offering no good will and Chrysler refuses to help as the mileage is 114,000. I still owe close to $13,000 on this vehicle and to replace the engine it is going to cost $7,800.

My car will stall and then accelerate very quickly. If I am driving and trying to accelerate my car will stall almost cutting off. This usually happens around a speed of 25/30 mile per hour. I also experienced deceleration while driving on the highway at 60/65 mph. This is very scary. Also when I am in reverse my transmission makes a knocking sound. My engine light constantly comes on. Heat vapors comes from the hood of the car.

The engine shuts off randomly while driving

- Severna Park, MD, USA

My car would not start on a number of occasions--the starter would make noise but the engine would not start. It usually started on the second or third try. I received a recall notice for defective tipm unit but was told that the part was not in stock. Well over a year later, the company still does not have any in stock. In addition, I have experienced my horn randomly doing off (sounds like the panic alarm) even though the car was running and in motion. Jeep should be much more proactive about this as an stalls during driving as a result of a tipm defect could case bodily harm to the driver, passengers, and others on the road.

Vehicle has completely shut down while driving 5 times in the recent past. 1X19 Oct; 2X31 Oct; 2X7nov. The vehicle completely shuts off while driving. This is very dangerous as all power is lost for breaks, steering, and obviously no acceleration. Chrysler safety recall P54 has been applied prior to these issues. Dealer and Chrysler are charging me customer (at my expense) to flash new software files on the vehicle computers. I sense this is very likely a much broader safety issue and am hoping our government (NHTSA) officials will investigate before someone is injured as a result of this.

- Dunlap, IL, USA

Since safety recall P54 was applied, my vehicle has completely died while driving on 5 separate occasions 1 on 19oct, 2on31oct, and 2on7nov. The vehicle is currently at sam lehman Chrysler Jeep dealership in peoria, il. They claim that I need new software at my expense to address the vehicle shut downs. Attached transcript is with Chrysler. They do not appear to take this safety issue very seriously.
