Brake light on dash while boosting
 
Hi, I've noticed lately my Brake light on the dash will come on while I'm boosting. Not all the time but it does it randomly. I checked my fluids and the levels are good. Sam at GTM confirmed it isn't something he programmed with UPREV as a warning light, which makes me feel better.

I'm just wondering if this is a random glitch or if it means something funny is going on with the car. She runs flawless otherwise. Could it be something related to an electrical glitch, a sign of the alternator going bad (less than 14k miles on the car), or something brake or traction control related? Could it be cuz I'm losing some traction while it is boosting so the brake light trips slightly before the VDC kicks on?

How much fluid do you have?

I have the same thing happen to me sometimes whenever I am WOT shifting into 2 and 3. It started after I ground my navtool to my ebrake, so I am afraid I over tightened it. But there haven't been any problems yet, and its been happening for over a month now.

Sounds like to low of fluid. Even though the level may seem good it's probably not enough under acceleration. Just make sure.

Thanks guys, the fluid level is good. With the car on level ground, the brake fluid is at the max fill line.

Just noticed the same problem recently, any solution?

have you replaced/removed your steering wheel? more than likely its your steering wheel positioning sensor.

Have you checked your brake fluid levels?

Did not see that one, was jumping through quickly.
I know with some 350z the brake light would come on with the brake fluid level was getting low. Mine has done this before, but I never felt power loss or the car hold back.

Sounds like your VTECH pressure is way too high!

Yeah, SPOHN was right. Even though the brake fluid level seemed fine, I decided to add a little bit more in there anyways. It hasn't reappeared since.

I had the same problem a few months ago
I decided to add a bit more brake fluid and the light never came back ,, the oil level is now a bit higher than the Full line on the side.
