Pack Performance and Launch Mode Limits

[Garlan Garner]

Now what fun would that be?

@Garlan Garner, I think you're missing the larger point. This has nothing to do with Tesla assuring safety and quality control with their product, and everything to do with the manner in which they chose to do so. And now people reporting a new warning, ninja'd into your owners manual to look like it was always there. It's all a mega "WTF?!" move.

Also Garlan, how 'bout them Bears?

The Bears are who they have always been. Unlike the Cubs. How bout them Cubs and Blackhawks?

HOW do you all know that it's not about safety?

 

[Garlan Garner]

Where did this concept that the car will catch fire come from?

From Tesla saying that the contactors in the inverter have overheated when large amounts of current traversed through them. They said that this large amount of current is beyond the limited current of any car, however its a known issue that poses no risk.

Based on what tesla stated about the issue tesla has only said it will cause drive train damage. Though since tesla has been lacking transparency your concern could be valid.

Tesla has been more transparent than any auto company I know of. Name another CEO that tweets about updates and company direction and such. Name another CEO that has periodic invitations of tours of their factories.

It may not be exactly what you want, however name a more transparent auto company.

Again...what does Tesla consider to be the drivetrain? The Contactor is in the drivetrain. The massive inverter is in the drivetrain. Everything but the battery and the cabin is part of the drivetrain.

If it were Tesla would have to report it immediately to the NHTSA and there would be a recall. Also they never said it was a safety issue in the email to @Tech_Guy and finally the new warning in the manual doesn't mention safety. It's obviously about trying to avoid warranty claims.

I was thinking that also. That the battery was excluded from the drive train. Which is why I couldn't understand how doing an upgrade to 100kw removed the LM limitation? But since it does eliminate the LM limitation, I assume the battery is part of the drive train.
So if the battery is included, the specific type of damage could be fire related. Though like with the place I work and others have stated, if it was fire related you need to report it as such and act immediately on a recall or risk being shutdown.
So therefore I think fire risk is off the table.

Please, that's not "transparency" that's building enthusiasm for the brand, salesmanship.

You beat me to it.

 

[azdryheat]

I'm assuming this wasn't always in there...but there's now a note in the manual that mirrors the official response someone posted several pages back

This is not in my manual that I downloaded 7/13/16. I ordered mine on 7/11/16. They need to either refund or remove this restriction.
Has anyone received a response from Tesla yet?

Yeah one or two have plus there's an article and response on electrik.

 

[azdryheat]

So just checked my manual in my P85DL and it has the added bit about tracking the use of launch mode, which leads me to believe this might affect P85Ds with the ludicrous upgrades. Someone give me a good reason why I shouldn't call tesla right now and ask for my 5k back.

No good reason. They owe my 10K. This is not what I bought.

Its not a safety issue because its already limited. If they would have left it unlimited...it would be a safety issue. Tesla remedied this before it became a safety issue.

 

[Garlan Garner]

There ya go.

That's a remedy.
Exercising the Lemon Law is also a remedy.

At least we have some remedies on the table and not just a lot of complaining. Who's first?

 

[Garlan Garner]

I totally disagree. They are telling us what they are doing. If it results in enthusiasm or salesmanship...fine.

Still...name a more transparent company. What is a more transparent auto company?

Why don't you guys answer my questions?

 

[MP3Mike]

This is the part I do not understand. Where after X times using launch mode at 1600 amps causes damage but launching unlimited times at 1600 amps doesn't ? When empirical testing shows no measurable difference in track results between using launch mode and just mashing the accelerator.

But do we really know that you have to use launch mode to increase the counter? They say the limit only impacts launch mode, but we have people here who say it impacts non-launch mode too, so what they have said isn't 100% accurate.

 

[msnow]

Still requires NHTSA notification and recall notices and they have never mentioned it was a safety issue.

The Battery and Drivetrain have to support one another.

Even if Tesla inserted a nuclear reactor in the frunk...you have to modify the inverter to use all of the power of the nuclear reactor. There will have to be new contactors and such.

Do you guys know what the contactor is?

 

[Zhelko Dimic]

Look, Tesla didn't handle this properly (yet, maybe they'll come clean?), but if any of you guys think there is anyone even remotely as ethical as Tesla in the car business, you're sorely mistaken.

I'm a car guy, and like cars a bit more than my budget can support for brand new ones, so I've been buying used performance vehicles for awhile, and have learned that everyone has way more skeletons in the closet than Tesla.

Porsche has exploding engines, BMW/Mini has suspension that can collapse at speed and kill you, etc... These are all known problems that manufacturers have handled in very, very poor ways compared to Tesla.

I'm not really defending Tesla, they screwed up this one; I'm just saying, even with this faux-pas, they suck waaaay less than others. So I find all the 'moral outrage' a touch over the top; it is worth talking about, but I hope context I provide is useful.

You don't have list non-issues with NHTSA. Dangerous Launch mode does not have to be listed because it does not exist.

The whole rant on this thread is due to folks not having the unlimited (possibly dangerous) launch modes they thought they bought.
