Z is acting up
Hey guys drove the z today and I noticed that it was shooting little white clouds some time. And I had a friend jump in and rev it and it acted as if it studdered and shot allot of black smoke out. The tips are stupid black and it reaks when u start it up. Do they run this rich stock? Car is stock btw. It’s a 2015 z07 manual 24k miles ever since we bought it, it also had this thing come up service rear axle and when I take slight turns the traction control comes on and aggressively try’s correcting the car. Only mod is different tires but same size and non runflats this time.
Btw the car stayed at 210-220 coolant and oil temp for a very long time over 30 minutes. Car was heat soaked felt slow. It’s fine now.
Has warrenty so I’m gonna take it in for my pops but I would like to see if anyone else had these issues.

These "service rear axle" warnings are becoming reported more and more. My 16 is in the shop right now looking for what is causing it. No word yet. I'll post when I have some news worth reading. I haven't been able to find any info searching here, only seeing other that are having it occur.

yeah but it never went past 220 which is normal right? I was beating on it bad up to 150mph in Mexico down south. But before going there it was shooting white little smoke out the exhaust when gunning it.

it was doing some freaky **** wanting to damn swing out uncontrollably. I really don’t like the traction control I drive with it off or even when I have it off and I do a burn out and smoke em soon as the back end goes out traction control came in and I’m not shitting you took me side to side while the brakes were going crazy doing it’s own thing and almost lost it. I had full control the system went crazy. Happen to my 56 year old father

There are two levels of rear axle shut down. Service rear axle then rear axle system off. Depending on the level it will affect more systems. When it starts shutting off you can no longer turn off stability. Can't enter ptm, etc. When the rear axle system shuts off the stability control is overly sensitive and will apply brakes during low to moderate cornering g forces. There are a variety of things that cause this.
When the rear axle errors occur it will turn on TC and or stability and it will become overly corrective.

Something doesn't make sense. You say you had TC turned off but then it cut back in. That doesn't make sense since when it is off it won't turn back on. Also TC doesn't jerk you back and forth it cuts power first and if that doesn't keep a wheel from spinning it will apply a brake on the wheel that is losing traction so the power goes to the wheel with traction. How did you turn off TC and how did you turn off stability control? They are two separate functions.

With all due respect —-Did you ever think that maybe the above activity is contributing to the problem - beating on it bad prior to all the wonky service lights coming on and puffs of white smoke and other unexplained freaky **** when your 56 year old dad isn’t around to monitor this Mexican activity in what I am guessing is his car?

The Z06 shouldn't be having a problem with that.

Burning Brakes
Are burn outs in mexico somehow different than ones done in the United States?
You mention it twice so I'm wondering.
If you drive it "aggressively" with the nannies on, does it still behave the same?

The times mine shut off the rear axle system, I am 99% sure it did not affect the A/C and radio presets. There is something electrical that is affecting various systems. Communication between modules or something.

What is worse is when the problem gets half corrected, but your rear eLSD occasionally stops locking. Then you get no codes, stability still works, but only one tire spins and the dealer doesn't believe you that something is wrong because the technicians aren't "drivers" and have never drifted a car.

times in my life and probably beat it 6 times the other time it’s a DD for my pops and mom
