can we see this doc?

I had the same issue. Dealer told me to slow down or speed up. said they called GM and they are aware of the issue but don't have a solution yet. Issue went away after installing my MRT exhaust. Don't feel the vibration any longer.

[Teodog]

The information I posted is what was on the paperwork when I picked up the car, the Service Advisor had already left for the night.

Sorry I cannot provide anything specific regarding Doc ID #2756752. Just thought I'd share what I had learned for those that have been monitoring this thread for any news of a solution. Sounds like they may have the long awaited fix to this .......... annoying problem.

Will post an update with results after the replacement parts are installed.

Hey all,

I had a simalar issues with vibration. I have a '12 v6 auto and was having vibrations in the gas pedal, floor boards and gear shift. (found out if was important to be able to tell the service exactly where you fell the vibrations) it was happening to me between the speeds of 34-45mph and wasn't all the time. I could speed up or slow down to put a stop to the vibrations.

I finally took it to the shop and the service write wanted the main service guy to take a ride with me so i could show the guy. The guy came back and said there was no need me to take the mechanic out. There is a service bulition out on this (wouldn't give me the number for the bulition) but it deals with the Torq Converter. Which they replaced. Now after spending 2 days in the shop (had to wait on the torq converter to be shipped) I have no vibrations (so far, it was getting to the point where the vibration was happening every time I went anywhere.

Hope this helps some of you guys. If need be I can try and find out the number of the service bulition.

Had a similar but different issue with the shaking, I was in park and my car began to shake after around 10 minutes with the car running, No revving of the engine or blaring music and it just started to happen, one thing that I did notice is that I have a leak in my rear tire that I had patched about a month ago. I haven't tried to repeat it yet today but if it does any suggestions?

Am having the same issue with my 2012 camaro v6. My camaro just has over 6000 miles. Its at the dealership as we speak , went on drive this morning with tech to show vibration and he felt the vibration 2 times and agreed something is wrong.they had my car all day and i just received a call from service guy that they are keeping it overnight because they want there service manager to drive it cause they couldn't get it to vibrate when the tech went out for a second drive after having the car 7 hours.its very fustrating!

Did they fix it? Did the vibration go away?

[Teodog]

Took the car into the Dealer after work today. Will post results after I pick up the car, hopefully tomorrow after work.

I found out that Document ID #2756752 is Corporate Bulletin Number #11-03-09-001A: Vibration or Drone Type Noise.

[Teodog]

Picked up the car tonight and went for a short drive. I am glad to report that the replacement bushings made a significant improvment in reducing the vibration/drone.

I was able to replicate the vibration/drone in a few instances, but now minor and nothing to the extent from before the fix, i.e. it only lasted a few seconds versus being constant.

The Bulletin for this work mentioned in my previous post is for MY 2011, V6 with auto, and VIN past B9145905. Maybe someone knows about a change past that VIN number?

Am undecided at this point if the condition is still an issue to me.....am currently hyper-sensitive to any vibration/drone because I have lived with it for the past year, along with the frustration of waiting for a fix. The absence of help from the GM monitors to this board (not even a reply to PM) along with the deletion of threads, and fellow member being deemed a troll for posting about this issue still bug. Those of you with this vibration problem can probably relate.

I still luv this car..... it's looks turn heads...and I still find myself looking back at it after I park and walk away. Am still hooked on how the original Camaro design was blended into a modern car (always grin when turning the radio AM dial ).

Will do some more driving this weekend to see how much of the issue still exists when not specifically trying to replicate the problem.

Hey Everyone, so I just went through this whole thread and just wanted to throw in that I am having the same issue as the majority of the people. I have a 2012 1LT automatic born Nov '11. I have had it into the dealer for the issue but got nowhere with them, I left it with the for 3 days in total to diagnose and they were unable to replicate the issue, I also went out for a drive with the tech but in the time he gave me(5-10min) I wouldn't hitch... Of course. Only thing they said is maybe wait till it gets worse and bring it back then. Normally this occurs consistently going up hills and just recently even noticed it going down slight inclines keeping at consistent speed. I have actually noticed the stutter..hitch...hesitation... at speeds ranging between 30-60 always in the rpm range of 1500-2200.

I mentioned the problems to my father in law, who is an ase certified tech and been working in cars for probably 35 years, right away he thought it might be the throttle position sensor. He hasn't had the chance to work on any 5th gens yet though so that is just going off experience from other cars. Anyone looked into this at all? I've been consciously trying to notice the position of the pedal when the stutter starts and it does seem to happen in a certain spot, but I could just be hoping for a solution.

Really hoping to take something solid back to the dealer so this can get resolved, thanks everyone for all the input and hope we can get this fixed.

[sh4mrock]

Came across a couple other posts that it was a torque converter problem, any other input on that? Has anyone else had that replaced and solved the problem.

Going to stop at a different dealer tomorrow to see what they think.

[arod41]

After going back and forth with service guy and mechanic and them telling me they could not duplicate vibration issue. I finally was able to go on a test drive with shop foreman and this guy knows his stuff. He noticed the vibration issue immediately and able to duplicate issue all the time around 40mph to 50 MPH .... to make a long story short they had to replace the torque converter to fix issue. Now my car runs like a champ with no vibration issues at all. the service guy did said that my car was the first one they have seen with that issue. Hope this info helps

Add me. 2012 45th 2LT/RS. Started doing this a few weeks ago. Took it in after coming across this thread. They looked up my VIN and saw the torque convertor bulletin, etc. The transmission guy took it for a drive with their diagnostic laptop hooked up. It is indeed the torque converter. They ordered me a new one and will be fixing it as soon as the part comes in.

[mikeb513]

I had the same exact problem with my 2012 camaro. They had to replace the torque convertor also. Said that they have had other instances of this. It was all under warranty so it was covered. Drives perfect now.

[toyboy1980]

Hope this helps someone...

That's good news that this looks to be narrowed down. I had it at a different dealer yesterday and both the tech and foreman were able to feel the problem. They agreed that the issue seemed to be the torque convertor, parts ordered and should be fixed in a day or two. Can't wait to get back in it and hopefully have a nice smooth ride.

Glad this thread was here to help get this resolved, hopefully it helps others having the issue.

[sh4mrock]

Just picked her up and another one can be chalked up for bad torque converter. Almost feels a little weird not having the stutter lol

Back to enjoying my ride. Thanks again for the input.

Sweet! I'm still waiting for the part (torque converter) to come in. Hopefully soon.

[thejudgemeister]

My 2LT started with the vibration at around 3,200 miles. The dealer is saying that it is the torque converter. I am not convinced but they are replacing it under warranty. We will see. The vibration happens with minimal acceleration and between 1700 and 2000 RPMs in automatic or manual mode.

Wow. I step away from this thread for a bit and it turns into something completely different. I hadn't heard about the new issues with the 2012 Camaros. Glad to see so many are getting this taken care of. Let me know how things go for all of you.

Jeff, thanks for your interest. A few posts back I put up a copy of the GM service bulletin that addresses this issue. This document already existing sure made things smoother when getting the problem diagnosed. Now just waiting on a new torque converter to come in.

[mikercamaro]

I took my 2012 in with 4000 miles and has same issue with the transmission.They are ordering a new torque converter and installing this coming week.Will update if any other issues.

[porkrind]

Could a 2011 2LT fall under this fix?
