This is an issue that is happened twice now. It is only happen when it’s been extremely warm outside. I spend my half hour lunch break from work in my truck reading a book with the air conditioner on in the car running. Today after about 15 minutes in my car my hazard lights came on by themselves. Pushing the hazard light button does not make it stop. They only stop if I turn the car off and then back on again. I know my alarm is disabled because I got into the car in the first place and my keys are right next to me in the center console. Does anyone know what this means or has anyone else had this happen?


The original post above was written about a week or so ago.

Today was the second time this week it has happened and I now know HOW it happens- just not WHY. Calling Jeep was useless and the surrounding dealers had not heard of this happening.

I found that when I start my vehicle from inside the office with the remote, I tend to let it run for about 5-10 mins. to get the A/C going. Then I go out there and read a book. When I get in, I always push the start button on the dash- so the car is legit running. About 1/2 an hour from when I remote-start the car, the horn will honk 3x's and the flashers start going. The car does not turn off or anything. To get the flashers to stop you have to turn the car off and then back on again and they auto-cancel. I'm thinking this is in case you start the car, put your stuff in and then go back inside and forget your car is now in the driveway running??? It's just my hypothesis as I cannot get anywhere with Jeep.

Has anyone else had this happen? I'm just glad to know I can duplicate it.

This just happened to me today with my 19 Limited. No horn but the flashers came on, the dash switched to my tire pressure, and I couldn’t turn the flashers off. After 30 seconds or so they turned off. Did you ever figure anything else out with this situation?

@JeepCares are you listening? Sounds like a couple of users could use your help...

No-one has a clue, but here's what I think... I think it happens when you use the remote start and then get in, push the ignition button, and then sit there. When the vehicle has not moved, I think this may be an alert that it was started and now is running and it thinks that maybe you forgot- like it's in your driveway and could now be stolen. That's the ONLY time I've had it duplicate- after these exact scenarios.

Today was the only time it’s happened to me and I did use remote start to start my Jeep, hoped in and pushed the button then didn’t move. Exact same scenario you described.

Could it have anything to do with the charging/electrical system? I remember years ago in my wife's Commander, she had a battery that was getting old and it actually went into kind of a limp mode, where it turned off a lot of the electrical system and activated the hazard lights. Changed the battery and never happened again...we still have the Commander.

EDIT: This happened in the dead of summer in south Florida where it was very hot.

I have not had this happen but have you tried revering 2 feet and than forward 2 feet after you start your car for real ?

 

[hogeyphenogey]

I’ve not tried moving the car- but I was not looking for a way to stop it from happening but rather an answer as to WHY this was happening. Jeep dealers do not know- neither did anyone at the Jeep helpline. Just like when I asked why my radio channel changed when I got into the car- come to find out the radio channel you set when you set your seats to the memory controls- when you push a memory button it goes to that channel. No one at the local dealers nor at the Jeep helpline knew that. There’s a lot of technology that is inside of these and many people working for keep have no idea. So I tried to duplicate the flashers-horn scenario and the only thing that made it happen was what I found in the above posts.

Only way I could see that being by design would be if someone (a potential car thief?) gets in and sits there in it after closing the door without the key fob. If you get in with the fob it knows it's someone who's "allowed" to drive the vehicle.

So my question for you guys is, did you have the fob with you when you got in, or not?

 

[hogeyphenogey]

I could not have gotten into it without the remote on my person. Also, if you do remote start it, can you even get in and push the ignition without the remote???

Ok, that answers that. My thought was that the thief wouldn't have the fob. He could shim the door and get in, but nothing would happen when he goes to start the car... except perhaps the emergency flashers coming on. So I wonder if it has something to do with the fob. Perhaps the battery is low, or the circuitry that senses it has developed a problem. Dunno, just thinking through it and trying to help.

I'm wondering are you stepping on the brake and then pushing the button or just hopping in and pressing the button? To actually start the car you have to step on the brake first otherwise your just turning the accessories on as if you got in and just turned the key one click. ( I assume you are doing this but I always like to think of the simplest stuff first even if its dumb). Only other thing I can think of is maybe its a safety feature of some sort in case you have it in your garage with it started and the garage is closed? Maybe another deep dive into the owners manual will reveal something further? I do remember that if ya don't hit the start button after a while, like 15 minutes or something it is supposed to shut off so maybe that's a warning that it will shut off soon? Are ya sure your hitting the button or maybe that book is just too good and is making you forget?

When you use the remote start, all you have to do is push the ignition button to complete the start when you get into the vehicle, you dont have to push the brake pedal.
You only need to push the brake pedal when you get in and start the jeep without using the remote start.

Yes I had the fob in my pocket as usual.

Well that answers that. :|

 

[kevinjeepcherokee2019]

my jeep does this constantly when I go on my lunch breaks and sit in the car as well. However I do leave and get lunch and come back. Always on a hot day. Once it happens I can shut off and back on no problem. Jeep definitely needs to educate someone about this because everyone at the dealership thinks that I am nuts.

 

[Smith0424]

So this has also happened to me several times both in cold & hot weather ....it happens when the vehicle is idle for awhile...I have contacted jeep also and they have no idea why it happens but have had several concerned vehicle owners 🤷‍♀️

 

[argold_81]

This happened to me today for the first time. I've had my 2020 Cherokee for about a week now and I went to the gas station to air up the tires. I left the Cherokee running while I hopped out to air up the tires. As I was airing up a tire, I heard my horn honk lightly. I thought to myself well that was weird but kept airing up the tire and it honked again. At that point I was thinking what the heck?? I stopped with the tire and got inside the driver's side and noticed the emergency flashers on. I tried turning them off with the button and no luck. Turn the Cherokee off and on again was the only way I could get the flashers to turn off. The temp here is 35F-40F today and I have the standard plastic key (insert to start), no remote or push button start.
