I may be off topic but given the car is dead, how would you shift the car say to neutral to roll it out to get towed since the tranny is electrical(shift by wire) compared to the mechanically linked old transmission? Just wondering as this was one of my concerns with this be electronic shifting technology

In order to push or tow the vehicle in cases where the
transmission will not shift out of PARK (such as a dead
battery), a Manual Park Release is available.
Follow these steps to use the Manual Park Release:

1. Open the center console and locate the Manual Park
Release cover, remove it by snapping the cover away
from the console hinges.
2. Using a screwdriver or similar tool, push the metal
latch in towards the tether strap.
3. While the metal latch is the open position, simultaneously
pull upwards on the tether strap until it clicks
and releases out of the park position.

C'mon, Bill. I know you had the same answer. You seem to be the type that read the owners manual several times even before you bought your Jeep and that's a good thing for sure.

I never thought about the pedal. When it didnt start I ALWAYS had my foot on it enough to know that my foot was on it and it moved probably 3/4" so I always figured good enough. This morning I pressed hard enough to feel like I actually broke the pedal, Iike someone actually hot glued the pedal in place and I had to press hard enough to break the glue. Once that "glue" was broken the pedal went down like normal and it started right up. I Do not have that problem during the week when I use it every day.

After sitting for a few days its like the pedal freezes. Now I know, And not for nothing my dealer would have been no help on this one,
This happened to me just now as I was updating my UConnect software. After it updated, I sat in the car (it was in "on" mode but not running) "played" with the brake pedal a bit as I was fiddling with the radio. After 4-5 presses, the pedal froze right up and I couldn't start the car, since I couldn't depress the pedal.

I turned off the car completely to the off position, opened the car door, shut it, waited about 30 seconds for all the electronics to go off, then I tapped up and down on the brakes (there was only a very slight bit of give) and after a few times, the pedal released and went back to normal.

Anyone think this is something to worry about?

I'm wondering if my pressing of the brake pedal while the car was in "on" mode started some diagnostic procedure or something.

Probably nothing to worry about. You simply depleted the vacuum boost by depressing the brake pedal several times.

It's unlikely you started some diagnostic procedure

Hi guys. Im in Au, and remember having this problem in a MB back in 99. Turned out there was in issue with the booster. Do you notice the pedal getting softer as you sit at a red light for extended periods? The MB I had used to release the brakes slowly if you were on a hill.. (lost its vacuum pressure) and you would find yourself pushing harder and harder o the brake pedal.

Re: 2014 jgc wont start after sitting all weekend

Brings up another point - if you have the "hill holder" feature turned on, try turning it off but it sounds over a weekend the resovoir is loosing boost.

OK just tried on mine in the garage with engine off & in PARK (can see the brake lights reflect on door. Must be in run for lights to come on (may not be legal in states) but could check. Pumped til got hard then another dozen times. Never gets rock hard (different issue I have seen in other ABSs) but does get "hard". Always has about 1/4" play and lights come on at about half that i.e. move the brake pedal about 1/8" (3mm) and the lights come on. How far does yours have to move ? If more then the switch needs adjustment.

Brake switch adjustment (warning to remove negative battery connection and wait two minutes for SRS to discharge)- remove lower steering column cover (pop column trim rearward, remove five screws - one top, four at bottom), push brake pedal down fully, pull switch plunger as far out of housing as it will go (should click when adjusting), release brake (do not pull up) and switch will auto adjust, check for proper operaton.

ps I have tried to paraphrase the factory service manual since the T&C does not permit sharing of the contents with anyone without specific permission from CJF.

Thanks for this. Out of curiosity I just went out and played with it again. The vehicle hasn't been driven since yesterday. Perhaps our measurements are just off due to measuring method, but using a ruler and a flashlight to estimate best I could, with the vehicle in ACC:

- My brake lights don't go on until the pedal is depressed about 1/2" to 3/4".

- After pumping the brakes a few times, the pedal got hard again. There is actually some play like you mentioned. More than a 1/4" though; I would say maybe about 1/3", 1/2" or so.

- If I press all the way down within this bit of "easy" play before it gets hard, the brake lights do not come on. If I press just a tad further past the hardness (I was afraid to do it yesterday) the lights do come on.

So you say anything more than 1/8" to 1/4" of brake depression for the lights to come on is too much?

Re: 2014 jgc wont start after sitting all weekend

That is my opinion. If under warrenty, I would take to the dealer and tell him the brake switch needs adjustment.

Unfortunately the FSM does not give a spec I could find, just that it automatically adjusts.

ps from what I have seen, it is possible that pulling up hard on the brake pedal or something interferring between the pedal and the switch plunger could "adjust" the switch out of tolerance. Personally think 4-5mm would be my target. You do not want it too loose or it could pop out of cruise while driving or inadvertantly start the engine.
