2005 CTS-V. I seem to recall hearing about "spontaneous airbag deployment" on an auto-x course, but not sure if that's truth or urban legend. Thoughts?

Also, anybody know what stock class I'd be in?

Thanks!

I've seen it happen, but i wouldn't worry about it if I were you. Just go out there and have fun. You are in F Street class.

My anecdotes: I have seen 2 different V's get popped into to "Limp home mode" somehow on an autocross course.

No idea why, YMMV.

GM has the rollover sensors set on a hair trigger. I heard something that GM racing had directions on what fuses to pull.

I dont have a solid lead on information, but here is the result of some light searching...

no info, but gives rough expense http://www.ctsvowners.com/forum/27-track-racing/8045-air-bag-fuse.html

I have personally seen a camaro blow its bags on a normal autocross run. (small lot even) The risk is real, but there is a fix, just gotta find it.

Seems like all the evidence points toward it being a V2 (second gen) problem(?)

I've seen the supercharged one and a Camaro ZL1 have the airbag deploy.

berkeley you, Steve

Without going into great detail, I've had a string of bad car-related luck lately. Trying not to go for the trifecta.

I did it on Hoosiers for a full season and didn't have any problems. Saw 1.29G listed on the car's g-meter (not that I think it's all that accurate), so I think you'll be fine.

HA! Awesome. Saw the same pic/one of your posts either in one of the links above or in a google search

That's the same class I'll be in with my Mark VII before the mods begin!

Yeah, that was kind of funny. 30 seconds after posting that pic I was in Noelle's office asking if she was going this Sunday.

Not sure what I'll be driving, though.

Lol. F-stock, yes? (Car is rock-stock on street tires.) Oh, and I'd gladly offer up a seat, but in light of recent events, I'm kind of in "Don't borrow, don't lend" mode right now.

Also, did you have TC on or off? It seems there's some speculation that this may have some affect on the airbag thing.

Is there any way to pull a fuse and disable the airbags at an event?

It was linked earlier but I'd rather leave well enough alone. Will's post put me at ease. I'm good. Plus, it's not like she hasn't seen some rather "spirited" driving in the industrial park at 2AM.

Yeah, F Street. I'd go with traction & stability control fully off. The driver aid nannies are pretty intrusive on that car, IMO. If the system detects enough wheelspin, it'll apply the brake, and with the electronic throttle, no amount of mashing the pedal will override that. I remember one run when I forgot to turn it all off, and and trying to hold down the switch for 5 seconds (or whatever it was) during the run didn't work out so hot.

No worries about a co-drive. I can run my SC or my MR2, it's just that neither will be competitive.

There was a Philly Region event where the course included a hard left turn just before the exit trap. This was in a large stadium parking lot with fairly aggressive ridges and valleys for surface drainage. It so happened the left turn crossed over one of these saddles. Somebody ran a CTS-V there, and the car's controller unit saw a combination of hard steering input, transition from heavy throttle to heavy brake, and sudden switch from on-camber to off-camber pitch. It read this as an impending rollover and popped all the airbags, cut power, and brought the car to a dead halt. I believe the nice Onstar lady called and got an earful from the driver, but that could be a story embellishment.

I had seen this same car do fine at several previous events. It was just the perfect combination of strong inputs and odd terrain that panicked the car.

What year? Could be a V1 vs. V2 issue. We had another local guy running a V1 for a while and he never had any problems either.
