Software Update Coming to Fix Auto Stop/Start Issue

3532 Views 36 Replies 16 Participants Last post by  Sofrieta
Just by told by our dealer that Toyota is aware of the problem with the Auto Stop/Start feature and a software update to fix the issue is in the works. They're not sure how long that will take, but told me it's the intermittent setting on the windshield wipers that causes the problem; I should not use that setting until the software update. Hope it won't take too long, and that it works! Anyone else hearing this?

Asegúrese de decirles que lo prueben con los limpiaparabrisas en intermitente. Deberían poder replicar el problema.
[/CITA]
Esta bien gOk thanks for the information. I told them
I just called Toyota service that I can pick up the car that Toyota knows of that error that they recommend for now not to activate the Autostop function .. It seems like a mockery from Toyota. Now I don't know what right I will have because the car is a lemon.

Yeah, that doesn’t sound encouraging that they want you to pick it up without fixing the problem.
( Did I forget to mention I hate dealers?)
A bug in the software does not make a car "a lemon".
Toyota is well aware of the problem, which affects all of the CC models, and is working on a fix.
Once that's implemented, there should be no further problems with it.
In the mean time, just push the stupid Start/Stop button to deactivate that when you start your car!

This needed to be said THANK YOU!!(y)(y)(y) the stupid start-stop thing should be disabled any how its terrible for cars and causes nothing but wear to just gain 1 MPG and causes tons of extra money in the long run just a short list of long-term expenses battery, starter, and engine wear, transmission wear , electronics wear (On off repeatedly aint good) bring back the old days

Hopefully it will be a software error. Since they have been reporting these errors since December of last year and 4 months have passed and they have not been able to repair this software error.
I've heard that unplugging the hood latch sensor plug disables the Start/Stop.
One may also wish to turn off the notification about Start/Stop being disabled on your display screen.
Unplugging that might disable the remote start however...if that's important to you.
Again, these are just things I've read. Haven't tried it myself because I'm in the habit of turning it off with the button.

There's a lot of talk at the Rav4 World site about this. Seems to work on those...

I have also found a module for Toyota on-line that automatically turns it off every time the engine is started, but I haven't found one yet that is specific to the Cross. There are several out there for Rav4 and Highlander however. Not sure if those would work on a Cross. As more of our cars are on the road, someone will surely make one for the Cross.

I would try the regular corolla start stop disabler since they share platform and electronics, even the dash is the same.

That's a matter of opinion, since the problem has no real permanent fix it can be considered a lemon. I took it to 2 dealerships and no one could replicate it. I ended up trading the thing for a tacoma, and no more issues.
I totally disagree that this incident makes a car a lemon apparently you haven't experienced a "Lemon" a car that had the same problem fixed numerous times over and over only for the "same"
thing to reoccur that is a lemon, one glitch is not a lemon this could be anything from an unsealed harness to software to a fuse overloaded to a harness itself everybody is saying rain? has anybody tried wipers on without rain to see if it is indeed it is the water? or could it be an overloaded circuit hmm I wonder and to me it sounds like they upsold you that is unless they gave you the EXACT same deal ;) and ohh i have personal experience with car dealers and a lot of the time we would "Update the computer " (after we put on the new part it needed)(y)

Lemon Laws are not a matter of "opinion". They are well defined. There are differing Lemon Laws in every state. Of all the ones I'm familiar with, this problem does not qualify because there's a very easy work-around...simply pushing the Start/Stop button makes the problem go away, and the car works just fine when that's done.

Toyota is clearly aware of this problem, and (from what we hear) is working on a software update to fix it. Until that update is released, just push the Start/Stop button to make the problem disappear. A very minor, temporary inconvenience, which does not qualify any car as a "lemon" legally speaking.

I do believe that Toyota should offer customers the option to disable or default the Start/Stop feature to "off" till this problem is resolved however. It would be a nice gesture.

That stupid Automatic Start/Stop needs to have a permanent shut off feature. Period.

It is just not fair to impose this on your customers.

And, if this is some voltage issue, then, that's quite frightening, because, what happens if I use a lot of electric power inside the car (USB ports and infotainment system)?

This would mean that it's not just a wiper problem, but, perhaps, an electrical system issue in general -- and, that can't be fixed except with a recall.

I bought a 23 corolla cross a week ago and the first day it shut on. I had the start stop button in and intermittent wipers on. It said steering power low. I took it back to the dealership and they said Toyota is aware of this. I was told to disable the start stop button.
I talked to two dealerships about the issue. Both of them said that they had never heard of the issue and that Toyota does not have any service advisories for it. Both dealers said that I would have to pay $150 - $200 for a service call if they cannot replicate the issue, which is probably likely since the problem has only happened twice. It really upsets me that I have to pay that much for a service call for a brand new car with less than 1,500 miles. The CC is my first Toyota. For a company supposedly known for quality and service, Toyota sucks!
I think there is some sort of button for mechanical service next time it does it be sure to push it so it gets documented with Toyota and in the books for proof plus they'll probably have you take it in for service that way and they may scan it on the remotely when you press the button
If it happens again press the SOS button in the headliner and have it towed to the dealership. That's what I did when my two week old battery died. Good luck.
Just seen this
Got my car back from dealership yesterday. The issue is the wipers throwing too high of voltage when engaged at the same time as auto-stop/start. Toyota is aware of the issue and a software fix is expected in late April, I was told to call around the 1st of May to schedule update. Until then I was told to not operate intermittent wiper and auto-stop/start simultaneously. So I just turn off the stop start since wipers are a necessity in Seattle. This only happens when intermittent and stop/start engaged SIMULTANEOUSLY, so your car isn't going to stall on the freeway, only when stopped long enough to engage stop/start. To me, this is minor and something to be mindful of when buying a car model that hasn't been out for very long, sometimes bugs have to get worked out. Still an swesome little ride!!
