2014 Grand Cherokee 7" Screen Dead

On the weekend I started up my 2014 Overland and went for a short drive to get a coffee. Everything was fine. After restarting my vehicle the 7" screen was dead. All surrounding gauges were also dead. Fuel showed empty etc...
I tried restarting the vehicle several times and nothing worked. I then tried operating my 8.4" touchscreen and while it was on nothing worked. It was on but the screen was unresponsive. I couldn't change the radio or access anything. I drove around for an hour and shut the vehicle off for 30 minutes. When I restarted everything was back to normal and it hasn't happened since then.
Has anyone else had similar issues? Did you have it checked out at the dealership?
I'm kinda worried now that I didn't take the extended warranty but my 2011 Overland was perfect. Never had an issue so thats why I declined the extended warranty on the 2014.
Any feedback would be greatly appreciated!

Did your check engine light stay on after everything went back to normal? My light stayed on for a day after my screen went bezerk.

Re: 2014 Grand Cherokee 7" Screen Dead

Without the codes it is hard to tell but wonder if CJF is buying their software from Microsoft. Sounds like there needs to be a RESET button somewhere.

ps still have not heard of any Laredo's with electrical problems.

If the system does not detect the fault after several starts the light will go out, but the fault codes should still be stored.


OP - I'm not sure if it is the same for the '11, but we are being told that on the '14 the car does not completely shut down until the driver's door is opened and closed. Did you stay in the car with the door closed for those first few restarts?

One problem is not a reason to be worried about your extended Warranty choices. It could be a very small problem like grounding but your dealer needs to look at it as that is pretty major so I would expect a code was set. I personally watch a lot of threads on the radio, screens and HVAC controls. Haven't seen anything with this exact failure.

Re: 2014 Grand Cherokee 7" Screen Dead

'11-'14 has Retained Accessory Power which keeps power on after the engine stops and until either a door is opened or the system times out. My 88 Buicks have that.

We have several instances reported of the dash going ded while driving. Be interesting to see if the codes are the same.

Re: 2014 Grand Cherokee 7" Screen Dead

Dealership found a fault code for frozen screen however no corrective action was taken. It hasn't happened in the last week so I'm not going to worry about. At least they found the fault code and have it on record now.
Thanks to everyone for their feedback. I appreciate it.

Re: 2014 Grand Cherokee 7" Screen Dead

We had the exact same problem in our '14 Overland this evening. Left the house and everything was working fine. Got back in the Jeep and dead screen and no control of the 8.4" screen. Restarted the vehicle three times and no luck on the screen. Truck is off for the evening, and will not know if it is working until some time tomorrow.

Keep in mind, car is not really off until the door has been opened. Others posting this issue have noted that just restarting does not clear the issue

You may want to take it to the dealer and have them scan your vehicle for fault codes so they have a record of the occurrence even though there is nothing to fix. Thats what i did. It only happened to me once so far. That was over a week ago. Knock on wood. Thanks to all that responded, yes I was fully aware the vehicle power is not fully off until you open the door and thats what i tried several times with no luck.

Re: 2014 Grand Cherokee 7" Screen Dead

I just wanted to make sure you were aware anything that happens once with the electronics in a vehicle can be a fluke. The repeat starts may have not cleared the single occurance but I always tell people to visit thier dealer if it happens repeatedly.
