Yes sir, it does. Quick cough and done under seriously hard acceleration. I have to learn more about, and understand better the effects of a direct injection system as I understand the process but not all of the differences. I'm old, hell in my young days I adjusted carbs and set points.

Smoke from the tailpipes used to be a bad thing out of a car. Seems like it is running too rich. I would think that GM could tune the black smoke out. I can't complain about the power the car makes. Even though the smoke doesn't seem natural, I will concentrate on the airbag, shaking and reverse problems.

I had a call from GM on Tuesday saying that the new harness for my airbag warning had shipped. Dealer would be contacting me to arrange a service date. I thought to myself.... Finally, this is going to be over!

I received a call on Friday from the service manager. He stated that they needed to have my car back to get the cable number on the harness so that the dealer could order the harness. I said he must be confused because GM said the harness was shipped. He said that GM was wrong. They needed the car to tear it down and get the cable number. I told him they had already tore the car down on October 18th and 19th to get the cable number. He said they forgot to get the cable number. They needed to tear the car down again.

I was really frustrated at this point. He knew I was frustrated and suggested that if I didn't like it, I could take it back to the dealer I bought the car from. What? I explained the issues with his service department and he changed his tune by the end of the call. He said that he was new and was trying to make changes in the service department. I told him that I could put up with all the other annoyances if they could just fix the airbag and the transmission shake.

My car is really shaking bad in the 1300 to 1600 rpm range now. It is constant now. It used to only shake in V4 mode. Now it shakes badly in V4 and V8 mode. Only time it doesn't shake is going downhill or when accelerating. Now I have to drive it in 6th gear to stop the shaking.

I am totally regretting purchasing the car at this point. This will be the 3rd trip to the dealer for the airbag and we are not even close to fixing it. The dealer is treating me like I am the problem. Sounds like the dealer is pissed off because I didn't buy the car there. I bought the car the first week of November 2015. They didn't have a 2016 Camaro on their lot till February of 2016 and it was a V6.

I traded a nice black 2014 Camaro 2SS with white SS stripes without any issues. That car would be paid off by now. It couldn't match the performance of the 16, but it was never in the shop. The depreciation on the 16 could have paid for a supercharger on the 14 to narrow the performance gap.

If I could get airbag and shake fixed, I would be satisfied and could put this bad experience behind me.

At this point enough is enough. I have reached out to the original dealer I bought the car from. They are going to give me a loaner because of the distance away. They said they are going to make this right. They are known for good service unlike the dealer that I have been working with.

My plans to take the car to the dealer I bought the car from failed. Chevrolet is forcing me to finish the airbag issue with the local dealer.

I have taken the car back to local dealer and they supposedly have all the part numbers for the cables that are causing the airbag problems. They are still working with Chevrolet to get the cable shipped. It is still unbelievable to me that Chevrolet wouldn't track each and every part that went into the production of the car. How do you perform any recall without that kind of information?

I also begged the local dealer to look at the shudder issue that I have reported on 2 other visits. The shudder is constant now at 62 to 68 mph at 1300 to 1600 rpm in V4 mode going up a slight incline or level ground. Shudder only goes away if the car goes to V8 mode or going downhill or if I shift to 7th gear.

Surprise... the mechanic couldn't feel the shudder again.

It will probably take another 2 or 3 trips to the local dealer to get the airbag fixed. I see no end in sight. Then I will be forced to take to a competent dealer that is interested in customer service to get the shudder fixed.

So I brought my car in for the shudder issue since it has gotten worse over the past month. It went from a slight shaking feeling to a pretty significant shake. When I was telling the service tech my issues, he came out and said "that is the nature of the beast" in which I responded that was completely unacceptable. He said that that issue is pretty common on Silverado's and to not get my hopes up in a fix...

I don't understand how things like that can be simply passed over as "normal" in these cars.

Except for the airbag and the smoke, the performance has been flawless up to about 9k miles. The smoke has been stated as normal to direct injection on this forum.

The car never shuddered once until about 9k miles. I can't believe that GM can't fix the shudder issue. The car shouldn't be wore out at 9k miles. I also can't believe "that is the nature of the beast". If so, the shudder wouldn't start 9k miles into ownership. It would shudder from the first day of ownership. The car has never been abused. I have never done a burn out it in the car though I know it will.

I am thinking my shudder is either the AFM or the torque converter. I purchased a range device from Amazon and it was opened. Tried it on the car and the car would still go into V4 and shudder. Sent it back and was going to purchase another directly from Range when others on the forum mentioned the torque converter issues. I printed out the following link for my local dealer and tried to get them to look at the torque converter. They refused because this "ASE Certified" mechanic can't feel a 9.0 earthquake.

I am better off getting the shudder fixed elsewhere. Would drag out like this airbag. They are either pissed at me or incapable. I was never rude or cussed them... just disappointed. Maybe they took the disappointment for rudeness.

Go to another dealer, obviously the dealership you are dealing with are imcompitant idiots and you are better off not letting them touch your car

I had the airbag issue when I drove the car home from the dealer on day 1. It was raining and the wipers were on. Here is what the dealer did below I hope it helps fwiw the airbag light has never come on again.

Thanks, I will print out your fix for my local dealer. Hopefully either your fix or this new hard to get wiring harness will do the trick. I heard from someone else about a wiring workaround to keep from having to get a new harness. I would have preferred to get the rewire to keep from having to take the car back so many times.

I received a call from the service manager today telling me that the part was still on order for the airbag fix. Last notification from Chevrolet said the part wasn't available. I ask the dealer about the possibility of doing the connector rewire from document 4342010 that fixed JFM-jr's car. He said that it was impossible because the connector was damage. I'm thinking the mechanic originally tried the rewire fix and screwed the connector up. The service manager said we have to wait on Chevrolet. Been waiting 6 weeks already to get the airbag warning fixed.

I asked the service manager about my transmission shudder. He said to come in and we would drive the car to see if we could replicate. I was able to prove to him that the car shuddered badly within the first few miles. He thought it was a torque converter issue. I told him that nothing had changed with the car. I had originally reported the issue on October 4th and the mechanic had drove the car almost 80 miles on the October visit. Mechanic said there was no issue with car. I asked them to look at the car again on the November 3rd visit. The mechanic still could not replicate. It only took a few miles for the service manager to agree the car wasn’t right.

Service manager wants the car in shop next week to look at the shudder issue and offered me a loaner. Maybe I am getting somewhere on the shudder issue. I think the service manager is doing his best. He is caught in the middle with poor customer service by Chevrolet and mechanics that seem to be just collecting a check.

The mechanics have had my car so much that I am thinking they might have a Uber business on the side. If your Uber driver shows up in a black SS, might be mine.

If I can only get Chevrolet to ship the harness, maybe I can get my airbag fixed.

This JUST STARTED on my 2015 Silverado...at 20k miles. Now it's going in to be looked at, but I already know the outcome.

Black smoke...
When you floor the vehicle the ECU properly increases fuel injector pulse width to WOT (wide open throttle)parameters.
That means they are dumping as much fuel as they possibly can.
Full-rich condition.
This gives horsepower, but the large amounts of fuel also cools the pistons and cylinders.
Without all that rich fuel mixture, no engine would last long.

I have gave up on trying to fix the black smoke. Everyone tells me that it is normal. I can put up with a fuel-rich condition. I am all about more power and longevity of the engine and if others have the same smoke, it's probably not broke.

I think the rear speaker rattle and the NPP exhaust rattle will have to be fixed somewhere else or just live with those. Any fix will probably be short-term from what I read on this forum.

My goal now is to get the three remaining items that I deem still are issues. 1) Airbag of course 2) The transmission shudder that is getting worse by the day and now the service manager agrees is not right. 3) Noise on low speed turns when the car is cold. Now I know from this forum that it is the differential.

All of these items are repeatable and way out of the norm.

After 6 weeks, I am hopeful that he dealer will get started correcting the shudder next week. I am hoping to get a recording of the differential "groan" and get the dealer to maybe change the rear end fluid next week to see if the differential noise will go away. That will leave waiting on GM to get a part for a 1 year old vehicle. Didn't think that the biggest problem. Finding parts for a almost new car.
