    So, the weirdest thing happened. I went to remote start my truck with the fob and it didn't work. Then I tried it a few more times and it did. Then, with the truck running, I went to try to open the rear window from the buttons on the hatch. No go. I prob pushed both the lock/up and unlock/down buttons a couple times.

    Then I opened the driver door -- and the truck kept running! I then tried to open the rear window from the switch on the center console. Wouldn't work. Then I shut down the truck.

    Then..... even after multiple attempts I could not restart the truck normally! Or by using the fob! Dead!

    Walked away and waited a min, came back and tried again. Would not start! Sometimes I was able to get the AC on, but later nothing at all would happen when I pressed the Start button on the dash. Dead! (Note that the fob still worked to lock and unlock the doors no problem).

    Sooooo, then I went inside, pulled the battery from the fob, counted to five, reinstalled it and then the truck started up normally. Drove aways, shut down, came back ten minutes later and it started normally again. Whew.

    Any clue what happened?? I'm wondering if I stumbled on some weird button-pushing combo that shut down the system. Or that caused the fob to continually try to communicate with the ignition? Weird and unsettling! Needless to say I'm gonna be more careful in the future with remote start via the fob LOL. I'm not sure it's worth the convenience!

    Is it an aftermarket remote start system?

    I've read horror stories about aftermarket systems.

    No it’s the regular Toyota fob and system. I’m guessing I confused it somehow and it freaked. Was interested if anyone knows what happened.

    Also thought people should know in case it happens to them. I’m glad it occurred to me to pull the battery on the fob. I can’t know for sure, but nothing else I tried worked until I did that.

    That's good to hear. Even if you figure it out, I would mention it to your dealership. That way if it acts up after your 3/36 warranty expires, they may make it right since it was a documented issue while within the warranty period.

    I had a similar event this morning. Started it remotely and went out to get in hit the unlock button and it did not turn off. Opened the door still did not turn off. I pushed the brake and pushed the start button that turned it off. But would not start after. All lights and accessory system worked but would not start the vehicle. Had to walk away. I am go to try again. I will update a little later. I have a factory remote start as well.

    Yikes. I thought mine might have had to do with pressing on the door lock/unlock buttons on the hatch, after remote starting but before I went to open the driver's door. As if I'd confused the system. Your experience suggests there's definitely a bug in this factory remote start software -- my experience wasn't some bizarre one-off.

    What model and year do you have?

    Pls do let us know how you fixed it.

    As mentioned in my earlier post, I pulled the battery out of my keyfob and counted to 5 before reinstalling it. Then things worked normally. Whether that was coincidence or not who knows. But my theory was that the fob was still communicating with the truck and maybe I needed to stop that.

    I've had no problems since. I've done remote starts prob a half dozen times or so. What I haven't done is push any other buttons after the remote start. Just walked up to the driver's door, grabbed the handle and opened it. Whereupon the engine shut off as designed.

    But definitely reason to be cautious about this system!

    Whoa!! Two instances in the same day?

    Question…Is this remote start system on the truck itself, or is it a “remote” remote start through the app that runs through the internet? The reason I ask is that I thought I remember reading that toyota offered remote start through the entune app if you are connected.

    If it is a remote remote start, then maybe there was some sort of glitch at Toyota internet HQ that caused two similar incidents on the same day…

    To clarify, my one experience with this happening was back in July. Yoda said it happened to him this morning. These two cases are the only ones I know of.

    As noted in the thread, we both used our Toyota keyfobs to do the remote starts. We were using the method where you click the lock button on the fob three times, holding it down a few seconds on the third press.

    I have also used the "Remote Connect" system to remote start via the Toyota smartphone app. I used it several times before my Remote Connect subscription expired. It worked well each time. But this thread is not about that system. It's about remote starting via the keyfob -- not via the smartphone app.

    Ah got it. Hope this is figured out for you guys. Sucks to have this as a possibility hanging over your head.

    Side note: I kinda hoped it was remote remote, mostly because I want to pick a fight with toyota over our internet tethers. But today is not that day Toyota, today is not that day…

    carry on…:computercoffee:

    LOL Nice. As most y'all know, I'm very much against the ol' internet connected vehicle thing!

    My guess is the fob button got stuck and the fob kept transmitting.

    Update, I went back about an hour later and the 4 Runner started right up. Not sure if needed time to reset itself. Any thoughts?

    Glad to hear. I really don't know what to think. But my gut feeling is that the fob is communicating with the truck even when it's not supposed to be, and this is "confusing" the computer. So when you allow enough time to pass, or you pull the battery from the fob as I did, the communication stops.

    Regardless, this is clearly a bug in the system. The fob should not communicate anything more than its proximity unless a button is depressed. And the truck's computer should not allow a blabbering fob to cause this kind of problem. It's a big fail. Hopefully Toyota knows and will fix it with a software update -- and recall the fobs if there's also a mechanical problem there (eg buttons are getting stuck).
