Rev 4.2 Downloaded Early Sunday

Well, we now are running rev 4.2
So far the changes have not been obvious in driving. Will update as we discover interesting differences from 4.0. Love to hear from those that see or know what we might be looking for in the latest update. It does feel really cool that all this happens while I and the car are " sleeping". VIN 2859, 85std with most options

Is there some sort of Change History which is common in software updates, offered with this new rev?

You can go to the revision notes from the "T" at the top of the display.

To those who have gotten the new update: has it always come in the early morning hours?

It "comes" at any old time, but installs when driving is unlikely.

Should mean that the iOS app will be released soon. Does it have a "charging" schedule option now ?

Ugh... I'm STILL running on 1.15.14. No updates for my Sig VIN 871. I go down to the garage every morning and every evening just to check if the update message is waiting.

I guess you just don't resemble a guinea pig enough. Mixed blessing ... ;)

@appljd The DS at my friend's delivery last week sad the iOS will not be out until sometime in March. :(

Glad I'm not the only one still running 1.15.14. I wish there was a way to make the car request the update. I've been telling people about the update which makes the handles come out automatically as well as other features, What I really want to do is use and show off those features.

Commodore 64

Is there not a feature to check for updates from the car?
My car was delivered 1/19 (VIN 3271) and I just checked my version, which shows: 4.1 (1.19.13). Does this sound like a newer version? I do know my door handles present whenever I approach the door (~3 feet from car).

One thing that was consistently mentioned as fixed in v4.2 on TMC is the pano roof opening when done from the touchscreen. In v4.1 and some previous builds, it would always stop at the vent position no matter what percentage opening was requested. When opened from the steering wheel scroll wheel, behaviour was correct.

v4.2 allows proper pano behaviour from the 17' screen.

A lot of the spurious error messages owners with v4.1 were getting (TPMS warnings, 12V battery fault, etc...) have also been addressed, and now occur only when true.

Tesla also removed the screen sleep option (was supposed to reduce battery drain while parked, but apparently caused other issues).

I am sure there are other tweaks, those are the ones a remember off-hand.


The most current software is version 4.2 which addresses some of the bugs present in 4.1 and, according to people who have already updated, disables the "sleep" function previously accessed with the range toggle on the control panel (not to be confused with the range charge toggle found on the charging screen) and is designed to reduce the high single digit range loss that occurs overnight.This feature is generally believed to be the culprit behind a multitude of bugs which by all accounts seem to decrease after installation of the 4.2 update. Reportedly, Tesla will re-release this function if/ when it's ready for prime time. The update is being distributed randomly to batches of cars at a time.

The new Tesla Addicts Preferred Program for Early Distribution (TAPPED) provides access to software updates on the day they are released for a nominal fee of $800.00/ year. Any takers? ;)

@mkh: Wait a minute..... I used to check the My Garage page incessantly looking for the time to configure. Then I used to check the My Garage page incessantly looking for the Design button. Currently I check my email incessantly looking for my final paperwork, and double check my phone for missed calls with a California area code (and just for good measure check the My Garage page in case I'm the first person who was ever notified of their VIN or Car has Completed Production via the website). Now you tell me that even after the car arrives I will probably obsess over software updates? When does the madness end?

We're waiting for an update on that, please hold....

It's even better now. Now you have to go out to the car every hour to see if the update has requested permission to install, or check the release # to see if a stealth update has happened when you weren't looking. Provides much more exercise. Your doctor would approve.

I think that cars due for release in the next few weeks will still be using 4.1. The main 4.2 feature is the removal of the sleep function which was causing numerous problems. The other feature that has been addressed in 4.2 is the windshield wipers which others say are now well behaved, and the door handles apparently are working better in 4.2. Hardware releases include new vents for defogging/defrosting. It sounds like they are trying to get the new vents into the northern climates first. Tesla has apparently announced that they are planning to re-release the sleep function again in the near future .

For those of you still not running all the features in 4.1--you got trapped in the "Bug world". Tesla was most likely planning a large release of 4.1 but cut it short based on all of the bugs. They then worked on a fix (4.2)--- released it slowly--and this continues to be the case. Have patience it is likely that most will have 4.2 and IOS by March.

@Bobinfla--the Madness is not likely to end anytime soon--but isn't it fun. Just think what version 104.2 will offer. Maybe a SpaceX ride!

My 2 personal requests would be the charge timer and recognizing the key FOB to adjust the personal profile before you enter the car

Don't know if it's related, but after the update to 4.2, we were stopped at Harris Ranch to charge up and after starting to charge for a while, the charging stopped after some tens of miles. It still showed that it was charging, just no current flow- only voltage. I stopped it and restarted charging and this time it made it ok.

Then we stopped at Gilroy SCs and hoped to top it off before the last leg home. We never were able to get any current flow. A gentleman ( who got his car the same time we did!) in another white S offered us the Driver Experience phone number. We called and they were unable to resolve the issue- a service stop tomorrow at the Menlo Service center is called for.

We made it home with plenty of miles left and charging in our garage works fine.

It's a mystery. Will post any developments. Will see if any one else had similar problems.


We are not alone.

At the risk of upsetting my fellow obsessives on this forum it is bothering me that everyone is calling it an "IOS". I am of course also an Apple fan boy so IOS (iPhone Operating System) is specifically for the Apple iPhone family (iPad and soon desktops).

So is Tesla really calling their OS (Operating System) an "IOS"?

@ziggy -- you can relax. Pretty sure everyone is referring to the iPhone/iPad app that is supposed to be showing up soon.

To be fully pedantic, the operating system on Apple iPhones, iPads, etc. is iOS, whereas IOS is the network infrastructure software that runs on Cisco routers & networking hardware.

/me ducks to avoid virtual tomatoes hurled at blinding speeds. ;)

@Oaktowner - I sure hope they ship an Android app at the same time. It would be a shame to ship an app for the phone that continues to slip in market share at the expense of the OS with a larger share (Apple is now the third manufacturer by volume of smartphones behind Samsung and LG, and there are tons of other Android manufacturers).

@rlpm - Right you are about Cisco. Cisco agreed to license the trademark to Apple. I am curious what Tesla calls their OS..
It would be nice if there were a blog or something where we could see the OS changes.. Maybe there is one?

@ziggy - If you have a Model S, release notes are available by tapping the Tesla logo at the top of the 17" screen. I'm not sure Tesla would be willing to post the release notes for everyone to see. But they could make it accessible only to those accounts on this website with an active reservation or a completed delivery. And I think the operating system running on the instrument panel and touchscreen is called linux. :)

@jat - I've not heard that Tesla intends to ship the iOS & Android apps at significantly different times. This links says in "a month or so" of Dec 21st. So that would be, uhm, today!

Watch out for those "or so" weasel words. They're awfully stretchy.

next month of what year ? ;)

I have to say this whole Tesla car experience feels so much like a software development experience.

The people behind the Tesla think like app developers (about time in my opinion).. get the best thing out there that is reasonably done.. spend time where it counts.. fix the inevitable bugs and problems down the road because we came up with a really great way to update things.. Sure the early folks will suffer a bit but when we fix it they will love us.. don't worry ship it!

Car hooked to my phone.. hmm, geek nirvana..

@Brian H - I agree, or so. ;)

Signature Performance VIN 277 - still on 1.15.14. I didn't mind not getting 4.0 and 4.1 with their bugs, but now that 4.2 is looking stable, I'm disappointed to still be on 1.15.14. I will add, though, that the car has been virtually flawless in the three months I've had it!
