Electronics Issues this morning w my Model S

I left my Model S on the street overnight last night on the dead end street where I live w about 200 miles of charge (though I know folks are told to leave their cars plugged in whenever possible). The temperature dipped down to about 43 degrees.

This morning I hopped into the car to run to a favorite coffee shop and immediately could see bunches of little issues with the computer system:
1) When putting the car in reverse, the rear camera would not automatically show on the display
2) I could not tune to any FM radio station (or get any audio to come from it whether in HD radio or not)
3) Blue tooth streaming of audio played with excessive choppiness if at all
4) No SFX on turn blinkers or hazard lights
5) My location on Google Maps could not keep up with my true location w/o being stopped and pressing to center the location of my car in the middle of the map
6) Unable to adjust the air suspension (it is greyed regardless of being in park or not, with brakes supressed or not).

I turned the power to the car completely off and back on again and cycled through the problems listed above that still persisted. I returned home and parked the car in the garage and plugged it in to my 240V plug there.

I hope the problems disappear when I check the car later on today -- but I'm a bit concerned.

Has anyone else experiences any issues like this or have any information about diagnosis or treatment before I call up Tesla (or anyone from Tesla reading this and know anything?).


cerjor, agree with mkh1437, when the wipers are set in auto-mode, this seems to be the current behavior. Think in one of the Software threads, there is a request to change this behavior. My Seville operating similarly when the auto-wipers were on, but since that one swipe only occurred when you 'started' the car (vs. the S starting up immediately), I never got wet. Now you open the door and the blade cleans the windshield with you standing next to an open door. Not desired - and am sure it will be addressed in a future software release.

Carefree +1 This is the best car I have ever driven (& it's electric). I am confident all this small stuff will be resolved and I am pleased to be part of the beta testing group.

Kevin and Carefree, thanks for your feedback. I have seen lots of Model S owners feedback that this is the best car they have ever driven, some of whom have experienced minor issues, others who seemingly have had the fortune of not running into any issues.

I guess if these are not serious technical issues ( for e.g. Something related to control of the inverter for regulating speed or steering related because there are issues with reading the steering), I need to calm down :-)

I am still a huge fan and just want to make sure I am making the right decision with going with a 1st gen Model S.

I still think it would be a good idea to make sure Tesla executives know about these issues...

To state the obvious: a reboot tends to fix a lot of the little electronic glitches I have experienced (e.g., no sound from the blinkers).

Regarding reboot, I have noticed that a long press of both steering wheel scroll wheels seems to reboot BOTH the touch screen and the instrument panel displays. Isn't that supposed to reboot the touch screen display only?

Carefree, sorry but I disagree. I do not accept to be considered a "beta tester". I expect to buy a finished product as I also expect an exquisite one. If the described issues are not handled properly and timely by TM I will not take my order. I will then climb back on the fence, wait to see what the beta testing period uncovers and their remedies, and then consider to sign up again. For the equivalent of USD 100,000 I expect "more". That said, I will give time to see what shall happen. I am not up for delivery before late summer at best so no rush.

Arturo M: I suspect that you are inadvertently holding a button down on the key fob. Years ago I discovered the same threat with an RX-7 that I owned. While walking away from the car I heard it unlock and realised that the remote was being triggered by other things in my pocket. I was 30 yards away from the car at the time!

GeirT, I fall into the middle category that christine_orita outlines - having only a single instance of no blinker sound and therefore a single reboot after it persisted across a couple of short trips. And like I think everyone who has their car, I just love it each time I 'need' to take it out on an errand or go to work - as it is so much fun to drive, and I make up excuses or volunteer to go to the store etc whenever the opportunity arrives.

All that being said - there are indeed numerous early quality issues, the known items on the due bill, and yes I believe we are all Beta testers for much of the 17in screen software. Based upon your comments, I strongly suggest you indeed cancel or defer, and let the early adopters work with TM to shake this completely out. While I never signed up for such duty, I will gladly do so, and as long as the fixes come along over the next few quarters, have no issue participating with TM in the process.

I feel like I was one of the last to get 4.1 on my Sig. When it finally came down last Wednesday all seemed fine until I tried to drive. I had an error showing the car needed service and it wouldn't go into drive or reverse. I am thinking no big deal. I will just reboot. The reboot got me on my way and all seemed good except I still showed the car needs service. I also no longer had an odometer on the instrument panel, couldn't use my phone or music from the steering wheel and a few other minor annoyances. Three more reboots didn't fix them. (I was starting to like the idea of a Sig with no odometer).

I called my service center in San Diego at 5:45 AM thinking I would leave a message. To my surprise I got a live person in Fremont. He figured they would need to log into my car and do a hard reset. (I wish I knew how to do that). So while I was at worked they did a remote reboot and all is good.

I just love my car and this company. Their level of service blows me away.

GeirT, I totally understand where you are coming from but I don't think the car with its current "minor" bugs and tweaks is for you. If you expect perfection when the car is being delivered to you then you will be disappointed. I am not saying what we are seeing right now is ideal but it is to be expected. I used to work in the software business and I know about early adopters:-) Wait until later this year and re-order the car then - you will be much happier.

Same problem on 4.1 today in the Bay Area in a garage, so definitely not cold related. Rebooting fixed everything but the ability to adjust the ride height. At the moment, I do not seem to be able to adjust the right height (it stays grayed out regardless of the car being in park with the brake pedal on).

DaveBs advice was right on, but I would add one more thing. I had the same problem and called the Tesla Roadside Assistance to document the car's problem. (866) 998-3752

It's important Tesla begin to build histories on the cars and any issues.

@psullivanassoc, you aren't the last Sig to get 4.1... I haven't gotten mine yet! I'm still running 1.15.14, and feeling very left out. :-(

I would like to know why the computers and software that cntrol the engine which must be very complex seem to have no problems...can't think of a post that mentions anything computer related with a driving problem.

Yet, there are literly dozens, and dozens of posts about computer problems with the secondary controls. It would seem this would actually be the more simple part of the car...turn radio on/off, lock/unlock the doors, work the headlights, pair a phone, etc.

If complicated motor controls are glitch free why is there such a circus with the other computer run parts of the car?


GM's response:

"If General Motors had developed technology like Microsoft, we would all be driving cars with the following characteristics:
*For no reason whatsoever, your car would crash twice a day.
*Every time they repainted the lines in the road, you would have to buy a new car.
*Occasionally your car would die on the freeway for no reason. You would have to pull over to the side of the road, close all of the windows, shut off the car, restart it, and reopen the windows before you could continue. For some reason, you would simply accept this.
*Occasionally, executing a maneuver such as a left turn would cause your car to shut down and refuse to restart, in which case you would have to reinstall the engine.
*Macintosh would make a car that was powered by the sun, was reliable, five times as fast and twice as easy to drive -- but would run on only five percent of the roads.
*The oil, water temperature, and alternator warning lights would all be replaced by a single "General Protection Fault" warning light.
*The airbag system would ask "Are you sure?" before deploying.
*Occasionally, for no reason whatsoever, your car would lock you out and refuse to let you in until you simultaneously lifted the door handle, turned the key and grabbed hold of the radio antenna.
*Every time GM introduced a new car, car buyers would have to learn to drive all over again because none of the controls would operate in the same manner as the old car.
*You'd have to press the "Start" button to turn the engine off.

I am really concerned now. I'd rather lose the $5000 deposit and cancel my order, than having to deal with this Windows crap.

I don't understand. TESLA wants to be as successful as Apple, yet it used Windows software for this great car? | JANUARY 7, 2013: I don't understand. TESLA wants to be as successful as Apple, yet it used Windows software for this great car?

I don't know where you got the impression they are using [Microsoft] Windows software for this car? The main 17" display is using Linux. The GUI was developed by Tesla and appears to run under X windows.

it feels to me that for (cash flow reasons) they have rushed out the car.
I don t buy the $100k Beta tester argument.
I now expect some more negative press, despite the fact that Tesla should be able to fix these issues remotely.
Still, the 12V battery seems a construction hardware issue.

Thanks to you all California/US people who go through this as in the UK I can t expect the car before the 2nd half of this year.

By then these issues better be solved (and no new ones) or the Tesla gloss will wear off.

We went through this with a baby stroller last year. The 4 moms Origami stroller is one of a kind, has regen wheels that charge lights, odometer and motorized collapse. Very flashy and high tech like the Model S. In fact it turned heads when we took it to a Model S event last year.

It's also a $1000 stroller.

My wife explicitly agreed to be a Beta customer so she got a discount. And sure enough things didn't go smoothly. We had to return 5 strollers and the thing would stop working at inopportune times.

I was mad at the company constantly though I liked having a cool stroller.

I'm taking delivery of the Model S in 3 weeks so its too late to get back on the fence. I just hope Tesla doesn't put me through the luxury Beta tester experience. I don't ever want to have to reboot my car!.

DanD : +1

Just received my Model S. Bluetooth will not connect to my iPhone 4S. The iPhone sees it but Model S just Blootooth Initializing. Please wait a moment. 3 hours later, still says the same thing. I tried resetting both displays (top two steering wheel buttons for main and then two scroll wheels in for center). No joy. Still the same problem. Called Roadside assistance (it's a Saturday). The are opening a ticket. Pretty disappointing to spend nearly $100K on a new vehicle and have it delivered without bluetooth capability. Audi would never do that.

My iPhone as well as my daughters paired immediately. And no issue going back and forth between the two of them while we're both in the car.

Every so often my iPhone 4 will no pair when I get in the car. Turing off the iPhone's bluetooth waiting a few seconds then turning it back on seems to fix it. I usually follow this maneuver with telling the Model S to connect.

Last night, I experienced the EXACT same list of problems, including no SFX with turn signals, no available car-height adjustment, no audio for FM, rear camera not turning on, map not showing location, etc. I googled just now "problem tesla computer" and got to this forum page, and upon reading, felt like DLPrager was my doppelganger. So exactly and specifically the issues I'm having, and no others, so far (I do love the car). I will try DaveB's suggested reboots, and report back.

RWFI. Maybe.

@Joyrider - I can speak to this from my experience managing an engineering team that developed flight critical software for aircraft.

Short answer is that all functionality must be documented (no "hey this is a neat idea") and designed, followed by a written TEST plan, and finally (for "Level-A" critical software such as engine or flight controls) a full branch-path TEST SOFTWARE must be designed and proven to show that all possible paths of the code have been shown to execute correctly and that any unused code is REMOVED to guarantee reliability.

Furthermore, the entire suite of (complex but automated) test must be run again as regression testing whenever ANY change is made to the code that results in a new release.

You can see why this approach is very stable. In fact, the FDA built their medical equipment critical software certification based on what the FAA has had for years, and the FAA took lots of input from Boeing, Rockwell, Honeywell and others on best practices.

Oh yes, the engineering cost is about 12x that of non-critical software development, it takes 3-20x longer (depending on budget and manpower) and the rate at which features are added or changed is best described as "glacial".

But thats the kind of effort that has produced very reliable power train, ABS braking, traction control, etc etc that we enjoy in the Model-S.

Personally, I am very willing to use agile software development techniques for maps, entertainment, lighting, audio, cabin amenities, sunroof, etc. so we get the features we all crave faster in exchange for being 'beta testers' and living thru some bugs.

Great explanation, pilotSteve, and very comforting! I share your toleration of bugs in non-critical systems.

I'm not getting my S for another month, but my real concern is the bad publicity that a very poor JD Power or Consumer Reports rating would generate. It would be great fodder for the Haters and very detrimental to the TM cause. I know TM is working very hard to resolve these issues - I just hope it's soon enough.


I've never hung out at a car forum before, although I assume there must be an owner's forum or club for just about any make. How common is it to see complaints? I know the threads or forums for every computer I've owned are full of complaints, and yet my experience has generally been ok.
