Engine turns off when driving randomly!!

Just want to know if any one has had or heard this happen. I have a 2011 Grand Cherokee with the hemi and only 40k miles. It has happened tonight on my way home from work on the highway. Just driving along and the engine just turned off with no indication at all. The instrument cluster on the dash say a nothing, no engine light, no computer problems reported to the truck on the dash., radio still playing. I did not even hear the engine turn off, no sputtering, or coughing. I pull over put the truck in park, push the ignition button and starts like nothing even happened. This is the third time this has happened on the highway in the past three months. Happens about once every month at any time of the day.

Any thoughts on the problem?

My 2012 hemi overland did that almost ten times one of them while traveling with my wife and my four months daughter and the last time this happened about five months ago . I took it to the dealer many times but they said thy can't fix a problem unless they can duplicate it .
So try your dealer and wish for the best and keep us updated , good luck man

Re: Engine turns off when driving randomly!!

I wonder if it might be a problem with the key fob. The dealership replaced the one I am using currently and it started happening shortly after that. Could it be a key fob with a battery problem as I sometimes have a hard time locking
, unlocking, or turning on the remote starter even when I am really close by. I never told the dealership about the engine turning off problem, so I will take it in tomorrow and see what they say.

Re: Engine turns off when driving randomly!!

Took it to the dealership and they say that due to the cold weather we had in January, my brake booster needs to be replaced. Thank god it was covered under warranty, but its gonna take two to three weeks to get the part in as its on backorder right now. Have a rental until the brake booster arrives. They say the vacuum line from the brake booster was cracked and that they believe this is causing the motor to randomly shut off. Makes no sense to me as this problem occurred months before the brake booster problem in January. I decided to trade in my GC for the new Cherokee Trailhawk instead of taking a chance of it happening again. Better safe then sorry down the road.

A vacuum leak can cause stalling, I am guessing the leak was probably slowly but surely growing for a while - the computer might have been able to compensate for it most of the time hence it didn't stall every time.

Either way, congrats on the new Trailhawk. The looks are growing on me as I see more and more on the road.

If I wanna check my brake booster for leaks by myself , can I or only the dealer can do that ?

Re: Engine turns off when driving randomly!!

Have cars that stop when driving and cars that won't stop when parked. To really screw up takes a computer.

ps Cherokee definitely looks better than an Aztec but not sure I want an SAV I can see over.
