Also notice it Used more fuel be doing this
Do what's the point
It's much easier to learn to turn it off when you start the vehicle.

Re: turning off auto shut down on 2016 wk2

As a programmer myself for all types of mechanical equipment like this there are many ways to accomplish this.

One thing I would guess jeep has built into the system diagnostics is the status of the starter that works with SS. I wonder if the PCM monitors the coil resistance of the starter and if it detects an open or shorted coil it will disable SS automatically. There has to be something like this built into the programming otherwise your car would have to be restarted manually every time you came to a stop in the event of a SS starter failure.

I wonder if it would be as simple as disconnecting the starter all together? Thereby disabling SS?

Re: turning off auto shut down on 2016 wk2

Is there perhaps a fuse that could be removed to disable the stop/start function? Don't know as I don't have that feature on the 2015 JGC.

I can't imagine Jeep selling vehicles here, (Phoenix), equipped with that stupid nonsense, when it's 115F and people are driving home in bumper to bumper, rush hour traffic. They're going to have so many irate customers in this part of the country, they won't know what to do with them all. I'm guessing this will be gone in a year. Without question it is one of the dumbest things I've ever heard of. Will the car run in neutral at a light without quitting?

LOL... oh, they're being sold in Phoenix and you can bet money that it was tested at the AZ proving grounds when it was being developed.

Unfortunately, it's a feature that's here to stay in the attempt to meet EPA mileage and emissions standards set by the Gubmunt. At least they're still giving you the ability to disable it if you don't want to use it. In the future, they may not.

The owners manual lists a whole slew of conditions under which the ESS is automatically disabled. There are several scenarios in which your 115F temps would probably do so.

Re: turning off auto shut down on 2016 wk2

From the owners manual. I hilighted the simple solution in red.

Possible Reasons The Engine Does Not Autostop

Prior to engine shut down, the system will check many safety and comfort conditions to see if they are fulfilled. Detailed information about the operation of the Stop/Start system may be viewed in the DID Stop/Start Screen. In the following situations, the engine will not stop:

• Driver’s seat belt is not buckled.
• Driver’s door is not closed.
• Battery temperature is too warm or cold.
• Battery charge is low.
• The vehicle is on a steep grade.
• Cabin heating or cooling is in process and an acceptable cabin temperature has not been achieved.
• HVAC is set to full defrost mode at a high blower speed.
• HVAC set to MAX A/C.
• Engine has not reached normal operating temperature.
• The transmission is not in a forward gear.
• Hood is open.
• Vehicle is in 4LO transfer case mode.
• Brake pedal is not pressed with sufficient pressure.
• STOP/START OFF switch is pressed.

Other Factors Which Can Inhibit Autostop Include:
• Accelerator pedal input.
• Engine temp too high.
• 5 MPH threshold not achieved from previous AUTOSTOP.
• Steering angle beyond threshold.
• ACC is on and speed is set.

It may be possible for the vehicle to be driven several times without the STOP/START system going into a STOP/START READY state under more extreme conditions of the items listed above.

Conditions That Will Cause The Engine To Start Automatically While In Autostop Mode:

• The transmission selector is moved out of DRIVE.
• To maintain cabin temperature comfort.
• HVAC is set to full defrost mode.
• HVAC system temperature or fan speed is manually adjusted.
• Battery voltage drops too low.
• Low brake vacuum (e.g. after several brake pedal applications).
• STOP/START OFF switch is pressed.
• A STOP/START system error occurs.
• 4WD system is put into 4LO mode.

It isn't a question of how much they were tested, or where. It's a question of customer acceptance. Most A/C systems in cars out here in extreme temperatures, (115F+), have a difficult time just keeping up with cooling in heavy, slow moving traffic. The JGC has a LOT of interior to keep cool. Shutting off the engine every few seconds at stop lights, and in bumper to bumper traffic in these conditions will NOT keep the interior cool enough. Especially with several people in the car. No one in their right mind is going to pay over $50K for a vehicle so they can sweat in it.

I've shut off mine for just a minute or 2 in those temps, in order to run in and grab something. And when I got back in the interior was hot as hell. If you leave a toddler or a pet inside a vehicle in those temps with the windows cracked, and a cop sees it, they'll break your windows to get them out. And when you show up, you'll be arrested.

Traffic in the Phoenix Metro area is horrible during the rush hour. When I was working, several of my co workers had 60 to 90 minute commutes going home in the hottest part of the day. Yet many only lived 20 miles away or less. Add in daily temperatures well into 3 digits for 4 months out of the year, with a car that shuts down every time it sits for a few seconds, and people are not going to be happy.

All that silly, stupid B.S. so a car won't shut down when you don't want it to in the first place? Insanity. As always, common sense is rarely a common commodity.

It is what it is. You have 2 choices...

- Press the button.
- Buy something that doesn't have ESS... while you still can.

I'm not a fan of the system either. Bitching about it isn't going to change it.

You're going to be waiting a long time. I've had my JGC a year last April. I just turned 3,000 miles. I'll tell you this much. If I found out my new Jeep had that system by surprise when I test drove it, I wouldn't have walked away from the dealership, I would have ran away. And I'm no different than anyone else who has lived in this part of the country for the last 25 years.
