Intermittent failure of Run-Stop button 2016 Summit

I've owned a new 2016 4x4 Summit 5.7L for over two months, and on upwards of 10 occasions thus far, pushing the Run-Stop button fails to start the engine. (Yes, my foot is always pressing the brake.)

The first time this occurred was the day I brought the vehicle home from the dealership and parked it in my driveway. A short while later I got into the vehicle to pull into the garage, only to find that the vehicle would not start. Pushing the button repeatedly, it would progress through Off--> Acc--> Run over and over but the engine would not start. The steering wheel would raise and lower, etc., and accessories would come on, but no engine start. I would start over via removing my foot from the break, then reapplying it, attempting to push the button again, but same result.

I quickly noticed however that the brake pedal soon felt different in that it had become persistently depressed, with very little play. Hmmm. At any rate, after periodically going back out to the car and attempting to start it during the next half hour, at one point, lo and behold, it started right up.

Over the ensuing weeks it would periodically act up again in exactly the same manner, except that after a minute or two it would finally start. However, a few mornings ago I got in the car to drive to work, and once again, it would not start, and four hours later I was still stuck in my garage and I missed a day of work.

Throughout the morning I was frequently on the phone with a service advisor at the dealership (Crown Jeep in Dublin, OH), but they would not send someone to my location to assist me even though they're only about 15 miles away. Meanwhile I put in a call that morning to Jeep Roadside Assistance, who sent out a flatbed to have it towed to the dealership, except I was unable to move the shifter out of Park, so towing was not possible.

Finally, around noon that day, I suddenly got the brilliant idea to try the remote start button on the key fob, whereupon the engine started right up. However, when I hopped in and tried to back the vehicle out of the garage, the shift lever would still not go out of Park! Not knowing what else to do, I decided to try pushing the Run-Stop button once, and the engine shut off. I then pushed it once more, and not only did the engine start right up, I was able to put it in gear and drive it to the dealership service center.

So, I get to the dealership and pull it into the service area, and met with the same service advisor that I had been speaking with throughout the morning. I had him get in the car and attempt to start the vehicle with the button, and it would not start. I also at that time pointed out to him the fact that the brake pedal was depressed and had very little play, which he acknowledged. He then went to push the button again and this time, wouldn't you know, the vehicle started right up. I was extremely fortunate that he was at least able to witness firsthand the problem at least once, so he knows that I'm not full of shit, even though it started up the next time he pushed the button .

The vehicle has now been at the dealership for two days, and of course it has been behaving perfectly normally ever since being in the hands of a technician/mechanic. They have been unable to figure out and diagnose the problem despite consulting with Chrysler engineers. Everyone is stumped and says they've never seen nor heard about this particular problem or behavior before. Lucky me. I'm driving a Dodge Dart while my $60,000.00 truck is playing possum while it's been gone over with a fine tooth comb. Nothing has turned up.

Of course, my grave concern is that they are eventually going to give me back the vehicle without anything having been accomplished, and once it is out of the shop, sooner or later it is of course going to start doing the same goddamn thing again. And then it will go right back to the dealership again.

Has anyone else experienced this same problem?

Re: Intermittent failure of Run-Stop button 2016 Summit

That's quite a story. Can't wait for the movie.


In the meantime, have you tried the other fob?


As for the brake pedal, as you repeatedly step on it with the car not running you are bleeding the vacuum from the booster until the pedal gets hard. This is normal.

Re: Intermittent failure of Run-Stop button 2016 Summit

Addendum: Whenever I've been going through these gymnastics trying to get the button to turn the engine on, the console display monotonously keeps reminding me to put my foot on the break. No shit, Sherlock.

I wonder if it could be as simple as a brake light switch?

Re: Intermittent failure of Run-Stop button 2016 Summit

Sorry to read of your problem. First off, you're lucky they even gave you a loaner car, let alone a spiffy Dart. Most Chrysler, Jeep, Dodge, Ram dealerships do not provide loaner cars.
As the post above stated, without the engine running, it's normal for the power brake booster to lose it's vacuum after a few applications resulting in a very hard pedal. Possibly the brake light switch is faulty? This would prevent the ecm from getting the proper signal to start the engine.
Good luck.

Re: Intermittent failure of Run-Stop button 2016 Summit

As with Bill DE,the foot pedal is normal,if I leave either of mine for a few days or week or more,the pedal remains "hard",thats normal.
Both our 11 and 15 have had no issue with the push start ever.
However,my friend had issue on his 15 with the same issue,whether my answer will help I don't know,as every vehicle is different,BUT,in his case,they had the vehicle 4 times before they figured it out and apparently the key was the issue,there was a problem with the 'chip' inside not responding consistently and recognizing the car AND gave no warning like "key has left vehicle"and otherwise functioned normally,they programmed a new key and has been problem free some 5 months now,again,whether this is the same problem for you,i don't know,they DID give him a new second key aswell as they were unsure if the 'chip' problem was in both keys as there were some questionable problems with that aswell,if I remember correctly,that one wouldn't work on the remote start.This was all discovered after 4 visits to the Dealership and months of annoyance and misery.
Like I said,i have had no issues with either my 11 or 15 so am just repeating what I was told.
Hope it helps the Dealer narrow the problem down,and yeah,it sucks when your pride n joy is down.
Just thinking too,i believe there was a thread with issues with people with CRD's and seemed they had win module,steering lock module and both keys replaced as they are all interconnected/programmed,not sure if its the same for gas models.

I'm no mechanic, but I too have been suspicious of a switch connected with the brakes.

Re: Intermittent failure of Run-Stop button 2016 Summit

It's interesting that you should mention this about the "key" by which I'm assuming you are referring to the key fob. Now that I think about it, there have been a couple of times when I've gotten in the vehicle with the key fob in my pocket, and the vehicle would not start but instead there was a message displayed in the instrument cluster which said something along the lines that there was no key fob. In both cases I simply pulled the same fob out of my pocket, put it back, and then the vehicle recognized the fob. ( I am single so I always use the same fob.)

Maybe we are getting somewhere here. Thank you.

Kinda why I asked in my first response if you tried the other one.

Re: Intermittent failure of Run-Stop button 2016 Summit

"First off, you're lucky they even gave you a loaner car, let alone a spiffy Dart. Most Chrysler, Jeep, Dodge, Ram dealerships do not provide loaner cars...."

Crown Jeep in Dublin, OH serves a rather affluent population of customers, and they are a huge dealership that sells everything from Mercedes to Kia's. When I brought my vehicle into the shop, even though it was on a busy Tuesday, there was never any question that they would be able to provide me with a loaner vehicle. In fact, when I told them that I was stranded that morning, they sent their shuttle to my location, ready to bring me in. I declined the offer because I needed to stay with my vehicle and get it to the dealership.

Re: Intermittent failure of Run-Stop button 2016 Summit

I had a similar problem several weeks ago with my 15 Summit. Got in the car, press the button and no start. Foot was on brake, like you, brake pedal was very hard. Had all the bells, and visuals working. Went through the ass, and start screens with no response. Did this several times and it finally started. No problem since.

Re: Intermittent failure of Run-Stop button 2016 Summit

I went back to the dealership today, spoke with a different and more experienced service advisor. I told him about the suspicions from this website that the key fob may be the problem, and he agreed that this could quite potentially be the problem. At any rate, I am now using the other key fob that came with the vehicle,and the dealership has ordered a new key fob to replace the first one. So far, the vehicle is behaving well.

If the above turns out to be true, I'm a bit disappointed that neither the dealership nor Chrysler engineering ever suspected a defective key fob in the first place. Many thanks to those who suspected the key fob

Time will tell.
