My Z is trying to kill me.
 

Yes my Z has finally decided to try and kill me. :roflpuke2:

First problem I have been having, about a couple of months ago the car started giving me the "maintenance: oil" warning. I know why this is happening. I changed out my oil after francorchamps and they forgot to reset the oil timer and that is the same thing they said and told me that they will fix it with my next oil change.

but after a week or two if I go half WOT or WOT this warning light blinks at around 4000-4500 RPM you know the one that looks like (I). most of the time if it happen I just let go of the throttle and it goes away, nissan dealership said its a built in safety for when you should change your engine and if you try to rev too high and that it shouldnt be a problem.

but the worst part is, if I KEEP going with that light on out of nowhere

VDC OFF. for no reason the VDC gets turned off. after going "wait wut?" I try to turn it back on. VDC stays off no matter how many times you press the VDC button. so I went to a parking lot to see if it really is off. car flies all over the place so yeah its off. if I turn the car off and on again VDC is turned back on.

this has happened around 5 times now and it is almost like the Z is trying to kill me for going too fast. :roflpuke2:

and you all know

Any idea what the hell would cause the car to suddenly disable VDC.

going to make an appointment with the dealership soon and hope they can fix it.

if any of the sensors or alignment is off, the VDC will turn off.

When yous tart the car it will be on, then it will decide hey, somethings not right.. why are the wheels going all crazy and the dudes still driving, ima just turn myself off.

<-- when i had my new suspension put in and before i had the alignment this would happen.

soo it senses something is wrong so it decides to disable all driving aids?

doesn't seem logic to me.

Well im not sure on the logic used but thats what it did for me when the alignmet was off. Urcase could just be some bad sensors

well if it senses something wrong and it stays on.... then it could accidently turn on when it shouldn't and it could cause you to loose control of the car and in turn cause you to wreck which would be Nissan's fault..... so the smart thing would be to turn it off so they can't be liable for it....

Which light is flashing? The traction light, the tire pressure light or the shift light? Use a picture from the owners manual to point it out.

:iagree:

it seems to be the brake warning like the one that looks like ((!))

That is the tire pressure indicator. If it is flashing that means it isn't getting a reading from the sensors. If it is steady then the tire pressure is low (or high).

I don't have the tire pressure sensors.

page 20 the brake warning light that is the light that flashes

the tire pressure looks more like (!) not ((!)) like the brake warning light

Oh, if it is the brake warning light then likely you are slightly low on brake fluid. When you accelerate hard the sensor in the reservoir gets a lower reading and the light comes on. If you did anything with the brake lines check for leaks, otherwise it has just dropped a little due to pad wear.

In the US the brake symbol is different, it says "BRAKE" instead of ((!)).

I see, still don't see why that would suddenly make my VDC turn off

Yes you do, it wants to kill you like you said in your first post. We just don't know why it wants to kill you. Did you use 87 octane? Did you let a Honda Civic pass you? Did you say the Hundai Genesis was better looking? You must have done something to bring on this behavior.

Your 2 problems would appear to be unrelated.

doesnt vdc work through the brakes as well? so if his car is detecting brake issues with the fluids or whatever reason that could trigger a vdc failure.

anyway. i think what we all can agree on is.. go get it checked out and let us know!

im not too sure how VDC in our cars work, but if its the same as esp, then it applies individual brakes to keep you inline with your target and to maintain control depending on steering position and where it thinks u want to go. if the brake reservoirs are low it could think that applying individual brakes would be dangerous in this scenario and shut off altogether.

the title of this thread reminds me of the line from the james bond goldfinger movie :D

vegitto-kun: you expect me to drive?
370z: no, mr. vegitto-kun, i expect you to die!

You might be right, it happened to me last year when I changed over the brake lines and had a small leak that tripped the light after a couple of days. Can't remember if it disabled VDC or not, but it very well could have.

I had a problem with the TPS sensor in my WS6 that would turn TC off randomly. Just a thought.

I lolled

me: Turn the VDC back on Z.
Z: I'm afraid I can't do that davy

Lol...:icon18:

I always get the best fuel for mah car, this happens if I speed up so the civic cant pass me and the genesis is not better looking

checked my brake fluid, its between max and min so Its perfect

I would top it up a little. Mine had only reached the half way point as well when the light came on going up steep hills or with hard acceleration.

Ah ok then, ...what do you put in there? I never bought brake fluid

If you don't have anything special in there now then you can essentially top off with any DOT-4 brake fluid.

the VDC off bug happened 3 times today -_-.

first time I wasn't even really going hard. I just got out of my driveway and I was just gently accelerating and out of nowhere VDC off at maybe 2000ish RPM.

then yeah my dad drove and was messing around -_- brake light and VDC off both time he drove

You have to top off the brake fluid to near max. I had the same problem on my car on the track last october where due to excessive pad wear the fluid level dropped. It caused the vdc to go off and the brake warning light to activate intermittently under hard acceleration.

:icon18:

I see, still doesn't explain why it happened this morning where I barely was moving :p

Like i said the same problem happened in my car. The fluid level is basically barely covering the sensor. Even the tiniest movement in the car will make the brake fluid slosh and splash in the master cylinder and uncover the sensor for sbort periods of time. Just top of the brake fluid and you should be fine. And dont forget to check the pads in case you need to change them

may be its time for transformers 3. woot

any updates on this!

went to custom import arts and tom emptied the brake fluid tank thing and pumped the brakes empty and all that **** and filled it up with DOT 5.1 brake fluid for free.

drove around for a hour and it seems like its solved and I wonder, but is it possible that my brakes work better now compared to the previous brake fluid or is it just my mind playing tricks.

Any time you bleed the brake system it fill usually feel better for a while as any air bubbles that developed are removed from the system. So even replacing with cheapo brake fluid you experience a temporary improvement, but with better brake fluid you pedal will stay feeling solid for longer.

so is dot 5.1 good, I know nothing about brake systems.

Yes, 5.1 is the current top spec (highest boiling point).

pretty awesome for him to give me that stuff for free. :roflpuke2:

but then again we just told him that we are taking the Z and GT-R to him for maintenance instead of the dealership + bought amuse vestito + repaint of the car depending on the price + potential twin turbo setup installed when they take out the engine to paint the engine bay....IF we repaint :roflpuke2:

edit: I read the tag for this topic.

I lolled hard.

another update, I did some sporty driving today and the warning light is gone so everything has been solved.

hooray for being able to drive properly again
