The dealer is speaking with GM technical assistance, I am waiting for a response now.

I should note this is not a minor pull, it will change lanes with heavy throttle and no tire slip.

Yea, changing lanes is definitely more severe than others describe. Read through this thread to see what others are experiencing.

My alignment was terrible from the factory. I had to hold the steering wheel like I was turning left to get my car to drive straight. It took the dealer 4 alignments to get the car to drive (mostly) right. The alignment guy clearly had no idea what he was doing.

What's the theory on how the eLSD would cause the car to pull to one side? If the clutch is applying too much pressure, that'd normally force the car straight. If the clutch is not applying enough pressure, that should just function more like an open differential. Unless there's something majorly wrong, I can't think of how the eLSD would cause the car to pull to one side.

Good luck. I'm sure you'll have it fixed soon. Hopefully it's something simple like a bad tire.

That why we do our own alignments.

Yeah. Most people simply don't have the attention to detail required to do a proper alignment on this car. After 4 failed dealership attempts, I ended up paying a local shop to work with me to get the car aligned using their alignment machine. Even then it wouldn't have been right if I hadn't been there to force them to get it within specs. Once we got it dialed in, the car drove beautifully.

A problem with your new Camaro, Sorry to hear that.. but.
Welcome to our club
Hopefully you don't feel the frustration some of us have felt and get this figured out quick.

[Fraxum]

I get tramlining as others have said. But I am sensitive to acceleration torque pull and nothing like that on my base A10. I hope you can get it sorted fast Ted. And let us know if you figure out the M6 bog. You will have lots of new customers!

[Mr. Wyndham]

I haven't noticed anything like this - going to stay tuned out of curiosity.

[PhreddT]

Like Mr. Wyndam posted, I have not experienced any kind of pull, while under acceleration or just cruising in mine.
I'm interested in knowing if changing the tires takes care of this, keep us posted when you get a chance to test it.

I have the same car. As you know Ted, you have been tuning mine and I've been doing hard 3rd gear WOT digs from 1500 to 6000 RPM for datalogging. Mine tracks straight as an arrow (Traction control and stabilitrak turned off).

I thought the eLSD was torque vectoring. Assuming it is, I would think that it could certainly apply more torque to one axle versus the other inappropriately if something is off base. Obviously it shouldn't do that in a straight line but if it did it seems like it could certainly cause it to pull if the drive wheels aren't getting the same amount of torque to each side.

I don't know much about these differentials so maybe this is flawed logic.

maybe wait a little longer for break in and change the rear lubricant. Take the car to your track day and run the car appropriately. After your track day, repeat the procedure and see if the eLSD has rectified itself after break in and track time. Just a thought...how many miles now? Go do some figure 8s in a large lot in both directions and double check the electrical connection to the rear.

I love me some Chevrolet.

With that said, why would GM build a PREMIUM performance vehicle like the ZLE in the middle of a fierce Michigan winter, and then leave it sitting on RDOT spec tires totally exposed to those elements? It is especially questionable for a hard working, well known and experienced builder/tuner like you. Let alone, a hard working, saved his ass off for years nobody like me.

I completely understand that GM is a for profit venture. I have no problem with that. I am a staunch Constitutionalist and as implied a supporter of the capitalist system. However, for GM to leave their greatest client base and supporters out to dry like this is totally unacceptable. We are the reason that Chevy builds halo cars. I truly hope that your problem is a tire issue and not a eLSD/software issue.

Sorry for the rant. Honestly, (as wrong as it may seem) to see that GM is playing this game with someone like you is somewhat rejuvenating for me.

Best of luck Ted.

I'm not sure why temperature would cause one tire to somehow grip better or worse than the other to this extent...Maybe a defective one, yet, but not temperature.

For what it's worth; mine has sat all winter in sub freezing temperatures (garage not heated), and there were no odd driving characteristics like what Ted is describing when I pulled it out this "spring" (still can't believe this weather...). The same holds for the brand new set I just had put on, as it sat for a few days in the 20s after I had them put on in the high 50s.

Goodyear worked pretty closely with Chevy/Camaro Team on the tire development for this car. I just can't imagine they would have overlooked production in Michigan in the winter if this would have been such a big issue....

Hi all,

I only have 550 miles on mine, but have not experienced any of these described issues. The alignment feels spot-on, though there is some tramlining on certain roads. The ride overall seems very similar to my '15 Z/28, just a bit stiffer.

I'm hoping this issue does not focus back to the eLSD. l really loved the 3.91 Torsen in the Z/28. l felt that was the perfect ratio/traction equation...and it would have been perfect in the ZLE with the even closer trans ratios and EXTRA power!

I live in the best weather area in the country, and never really have to worry about weather extremes. Either way, I'm going to keep monitoring this situation. Really, really hopeful it's not software related! OP...good luck with yours.

JJ

Welcome to my thread... and there's another one out there with quite a few others experiencing this.

I just got rid of the car...

Here's whole group of folks with the same type issue.
