Alarming nanny behavior

Left turn did he say.... How full was you gas tank. Gas tank has a Ridge in the middle and the power is well known to be cut out when making hard left turns on half tank or less.

First, do you have a automatic and hence extra buttons or is it a manual.

Second the standard TC is over protective and Terrible.
The sport mode, not the gay automatic sport transmission thing is very useful. It is what the normal TC should be.

If you can't drive around with it off you should go take lessons. This is the second car I've owned with it, both Subarus and they both were like this. The STI has a sport tc very similar to our cars and it works well.

Maybe this is specific to AT because I can have quite a bit of fun with VSC (which I assume is what you mean by Sport Mode) disabled on the MT...

I like having the nannies in general, but I'd rather trust 39 years of driving experience in all kinds of weather than have a system that could overreact like that.
What would happen if it did that on the highway in the rain because there was the slightest bit of slippage while changing lanes? It could cause a multiple car pileup. Granted that's an extreme example, but based on what happened this morning, I think it could happen. What would be the slightest of adjustments on my part could become a disaster with that kind of reaction by the electronics.

Except it wouldn't have done anything like that. It doesn't slam on the brakes, it just cuts power. If you're traveling at highway speed and it detects slip and cuts power you're barely going to slow down at all. There would be no pile up, etc.

Now on the other hand, if it didn't intervene and you spun out on the highway, that WOULD cause a pile up if there were any cars around you.

All that said, unless the automatic has different VSC/TC algorithms, I don't think it should be that invasive. If the slip indicator was lit up you either spun the tires or were on the verge of spinning out. You can get the car to spin without wheelspin, but generally the TC doesn't intervene until there the wheels are spinning by a certain %age (not sure what, but it does allow some wheelspin before cutting in). Now if it was stepping in because of a spin you should've heard and/or felt the ABS working the rear brakes. If the TC/VSC intervened before you felt anything, chances are you would've gone into a full out spin had the nannies been fully off. I can always tell ahead of time when they're going to step in on mine (it's manual, auto might be different?).

Depending on why it's intervening, it will cut throttle and/or apply brakes to stabilize the car. It doesn't always do both, depends on the situation.

I had forgotten about the fuel tank issue. Did anyone come up with a fix for that by the way?
Fuel level was low enough based on what you are saying, but the turn wasn't particularly aggressive.
Even if it was a fuel starvation problem, why would that make the traction light come on?
Is it possible that what actually happened was that the car abruptly lost speed due to fuel starvation and the computer, not taking that into account, saw the loss of speed and flashed the traction light? Have I been maligning the nanny when in fact it might not have done a thing except flash a warning?

I was recently driving in snowy weather on a backroad that appeared to be completely dry.
I was doing ~55MPH and romped on the gas at the bottom of a hill, and the ass stepped out, TC took control and straighened me out perfectly. No indication of ice, no visible snow on the road....

If I had had the TC disabled, I can guarantee that I would have been in the ditch or in the oncoming lane. (que all of the "I'm a great driver and I could have recovered" - Yeah Right...).

[Pokeguyjai]

I think you have to be driving really fast in order for the TC to be a problem. I just leave it fully on when I'm on the street. I would only consider turning it off when big boy rules apply for EVERYone involved.

The OP question is proof that the systems work well, Trac kicked in before he even realized there was a problem. Had the same thing happened at on the highway it could have saved his life.

Thanks anyway guys.. seems you don't understand beeing sarcastic...

Anyway, not saying i am a pro racer, but i am a drift instructor, and been road racing since 2004. aND IF I CRASH MY CAR.. Well i'll take responsability for it.

Fuel starvation will not occur at these speed.... Not in this car...

it does when you do hard lefts! look around.

I didn't say the car was not going to have some.. i said in his situation, it was impossible! You won't experienced that on street tire, and driving on the street!

I have taken enough hard left to know when i get it, and it's on very limited left turns with grippy tires.

If OP doesn't like traction control look in to this DIY traction override: http://www.ft86club.com/forums/showt...ction+override

Headlikeahole: Trac and VSC are safety features and in case of an emergency.

so is a crash helmet and a firesuit but I don't see everyone wearing one on their daily commute. The reason we don't is simple, It is not worth the extra hassle compared to our percieved benefit. That choice is a personal one, yes it could affect others, but so could every choice you make. If you chose to ride a bike insted of drive your car you could insure that you would never loose control and hit anyone with a 3000 pound bullet, but is it worth the hassle in your life to protect others? That's life, you make the choice and experience the consiquences of them, weather good or bad.

actually its happened on the street lots of times to me on stock tires..... so yeah. hard left going like 30-40km/h with no loss of traction, the power just cuz out cuz im below half tank taking a hard left.
