Thanks for the quick reply OnPoint!

1) tech tested spark and fuel injectors, so far so good. Yes- I've been directed to this forum using google regarding possible bad wires. Is there a TSB on this possibly?

2) I'll be getting this looked at again when I take it in for the diff.

3) Yeah, again was directed here when googling. Hope all is well after the replacement- biggest worry is the tech taking everything apart and putting it back together properly. :/ Just looking at pics of that under body with all the suspension parts to take apart is giving me an anxiety attack.

Cheers again, will update for those interested. Can't do anything (other than replace wires) myself in regards to the misfires.

The info provided on this Forum is priceless. The key to a lot is a GOOD dealership and service techs

Have had my 2017 Z06 M7 for almost a week now. 325 miles on it.

1. Can't seem to get to the 500 mile mark fast enough. Resolution will be to go for a quick 170 mile drive in the twisty hills (varying RPM and gears) and then promptly take her to the dealer for her oil change.

2. Under spirited acceleration, there was some loud screaming noises coming from the passenger seat area. Resolution was to pull over and threaten my wife with some duct tape. Screaming noise did not completely subside, but is occurring less frequently as my only passenger is becoming accustomed to the improved throttle response over my 2014 Z51.

3. Permanent smile on my face. Dealer said they can't help me with this. I believe it is an issue I can live with.

Its not as funny when you have to drive for 3,000 miles with a malfunctioning rear diff wreaking havoc on the fun.

djnice

No its not fixed, but your right I need to lighten up. Its just a car. When it starts getting hot the rear diff stops limiting slip then other systems are turned off. It does fine in a straight line, but everywhere I drive has corners.

Errrrr! My system shut me down off the line. The Generals response was the patented change my shifting.

Common problem? Timing retard and limp mode.
When a car is sold and warranted to perform on a track, it should be covered as sold. Let's not argue about continual performance at 82 deg etc. its not there. Things like AC, seat cooling etc are trivial compared to an advertised condition that can't be met. It's a corvette! We expect American roughness and overall GM quality. Where is the concern for the people that buy a purpose sold vehicle at retail no questions asked and then basically ignore (not cover) the failure of the primary selling point of the car. All things considered, these cars are still awesome and the bashing is unwarranted. Let's give em a chance and see where it goes on this one. Can anyone help get me to the right people? As a supplier to GM since before time... It would be nice to get some reciprocal treatment.
dependablegagedotnet. Good thread, even with the occasional headcases.

Window washer fluid is not working. Came from factory like this and yes still warranty. I wanted to check the fuse or fuses because i don't hear pump. I was told the pump is up front near the passenger headlight but haven't found it? Maybe factory forgot to put it in and that's why it's not working? LOL

I haven't had time but next week plan to address with TPTB at GM the fact their so called track car can be an EPIC fail
At the track and they have ZERO fixes.

Took the car in for the four cylinder shudder yesterday 8/8, was told 4-5 days. Gave me a nice Tahoe for a loaner at least.

djnice

What are your car specs? Did they say what causing the shudder in your car?

Do you happen to know if GM's warranty for the Z06 includes a loaner car if the service is more than one day?

Mine had an issue with popping out of first gear at least once every time I drove it. I tried everything to see if it was something I was doing. It wasn't. Went to the dealer 5 times about it. Finally they took the transaxle apart and inspected it. Showed me the work. Put it back together. Now it's much better, but it still happens every now and then. Have some rattles from the doors and panels. Everything else it ok. Seriously baddass car. I think of it more as a supreme grand tourer than a track car. (mine is not a Z07). It's also a helluva grocery getter.

djnice

So when it popped out of first you verified it was fully engaged before it popped out? Did it pop out from a start or after you were moving? Mine has popped out, but it is always if I didn't double check that it was fully engaged. Did they just adjust it or replace parts?

2015 A8 Z06, 3LZ stage one aero. No info given to me at this time. I did request a call back before any work starts so I am starting to get worried...

I don't know if it is included, I would assume so but you know what they say about that LOL. It is my daily driver so I would have needed something.

cossan512

I tried everything to change my driving style to work with the transaxel. Nothing worked. I could feel barely a little something was different when I would put it in first and it didn't seem right, then it would pop out. But it could not be put further in, and it would push my hand back if I tried to hold it in gear. I tried putting it in other gears before 1st. I tried everything I could think of to adapt to it. They took it apart and may have replaced some parts but I don't know to be honest. When I got it back it was much better. It still happens but very rarely now. Maybe 2x in 3K miles. Not really happy about it. But it's livable. I think it's a design flaw from cramming 7 gears into that tranaxel. When they took it apart everything looking brand new.

Got the car back today after rear diff replacement. Was only about a 5 mile drive from the dealer back home, but so far so good. Took them about 2 days from start of service to the time I got the call to pick it up.

Just hoping it works out and no issues pop up again. Would like to do some mods next year but think I'm gonna wait out the warranty- power isn't much an issue anyways since I'm having a hard time hooking it up on the street (have yet to try launch mode).

Krazy

I fully agree with that statement. It gets **** for being called a "Z06" but I really don't care what it's called. All the bells and whistles in it and living with the interior made me like this car a lot more than I thought I would when I picked it up. Incredible balance of looks/performance/comfort/features and the car finally gets a proper interior.

DebRedZR1

Interesting after you posted this noticed the AC on mine isn't a fraction of what the ZRs is. Window tint on the Z, not on the ZR. Definitely something wrong. Your D to C- is on point. When I get time another trip to the dealership

Mine used to work but for a year now the fans start and quit after 15-20 minutes and wont restart until the car sets for a while then the same. Had it in 3 times, the last time I was told that GM engineers were contacted and they told him they are designed to go off after 30 minutes as part of the power management system. All non safety related accessories are turned off so the battery is not drained. WOW really-who would design a ventilated seat that way and who would buy them. NO ONE is the answer to both.
