Jeep Computer??
« on: September 12, 2018, 01:54:24 PM »
Today I had a brief problem which, thinking about it afterwards, is slightly scary. My 2015 Sahara has generally been pretty good -- lots to like, but a couple of things make me wonder, and today's most of all: I was headed for an appointment (city streets) and it was getting a touch warm, so I tried to roll the (power) window down. Neither front window would move, though I could open and close the two rear windows. Before leaving the house I'd rolled up that front window, but now it would do nothing. After the appointment, when I got back in the Jeep, it worked fine, and was OK all the way home.

The other problems have been occasional. While everything was fine for the first few months I had it, I eventually discovered that once in a while the GPS doesn't properly boot, staying in a Garmin screen that obviously shows near the startup. This went on until a few months ago, when I read about a download that would cure the problem. So I applied it, and sure enough no more GPS problem.

But then after a while I noticed that the cruise control occasionally won't turn on. Once it's on it works fine, but sometimes pushing the on/off button does nothing. Sometimes I can push it later and it'll come on, other times it won't until after I've stopped, shut down, then restarted the engine.

Then a couple of days ago, I encountered the GPS startup screen again -- only once so far, but...  And then today, with the front windows...

Anybody know what's going on? Anyone else having that?

Larry, the electrical gremlins are out to get you!  ::) Sorry, I just couldn't pass that up.  But these things are frustrating!  You have my sympathy if not my knowledge.

Those problems stink.  They never happen when you need to show a service tech.  You might consider disconnecting the negative from the battery, let it sit for a 1/2 hour, and reconnect.  Maybe it needs a good reboot?

We have 24,000 miles on our 2016 and so far no problems.  We don't have the GPS option on the radio.  No problems with either the cruise or the windows.  Hopefully you'll get them resolved.

You know, when you have these mysterious problems that span multiple systems in a car, or RV, they almost always are  attributed to a bad ground somewhere.

I doubt that the window motors are computer controlled.  But a bad ground could effect both the GPS and windows, and a bunch of other stuff too.

Unless the jeep has voice recognition and normally responds to 'lower drivers window'?  Not likely as far as I know.

Ask your dealer if a software update is available. They can sometimes fix those nagging issues.

A very good thought, Muddy - thanks.

I've not seen anything on the web about software upgrades, Pam, but it's a good thought -- perhaps a dealer knows something, but... We'll check.
