Has anyone else noticed a mild ticking/tapping/fluttering coming from the rear of the motor? I only hear it if standing outside towards the front of the truck. I had it up on a lift and cannot pinpoint it and there are no exhaust leaks myself of the muffler guy could find. I thought maybe it was the injector noise from a direct injected motor? Thanks.

My apologies. It's a 2015 Tahoe with the 5.3 and automatic 6 speed transmission. It's silver if that helps.

Good dig with the color. Now because of that, even if I knew exactly what is wrong, I would not share it with you. It only makes perfect sense that if you post for help that we need the info I requested. If you want to be butt hurt because "you" were told to supply the info then adios! !@#$%^&*

I'm not "butt hurt." In fact I thought a little comedy/minor sarcasm was appropriate given how apparently angry you get over a first infraction. Filling out my signature now.

It's not up to me to monitor if it is an infraction. That is for the mediators. I am just a former tech/service manager and if asked for help we need certain things. It only makes sense that the year, make, model, engine and trans are needed "every time" a question is asked or put it in the signature because we that try to help will always look there if the info is not provided in the question. I did get the comedy/minor sarcasm because I did say it was a "good dig." Sometimes the typed comedy/sarcasm loses a bit in the translation because of just being typed instead of in person. I would have picked it up better as a comedy/sarcasm if I would have answered back with a response to your ask for help and then you did a thank you back adding the part about the color. That would have been hilarious!


Now that I have vented and don't feel so butt hurt myself I will try to answer and help you. Hopefully everyone on here reads this post and the word gets passed to give all that info instead of having to ask/demand it.

IMO the noise you are hearing is the injection system. They can be noisy sometimes. Should still be under warranty so take to the dealer and have them listen and advise and make sure you get a documentation of the visit for future warranty concerns. Always always always get documentation of "every" visit to the dealer. Now what will really set me off is if you have already taken it to the dealer for this and you did not share that info in your original post. Man, that would be the icing on the cake right there, by God!
As a former service manager, nothing drove me more nuts, besides the other info I asked for, than if a customer does not tell me their concerns and what may have been done or looked at and they present only part of that or it is not in chronological order. Details man, details! In order.

You get my sarcasm there?! Good day!


By the way, there is a guy on here that asked for help about 4 codes on his 96 Tahoe. He said the codes were exhaust related! Exhaust related? He wanted to know about running and idle and hard start problems. He got the codes for us and one was for MAF sensor, the other was for an oxygen sensor and another was for a misfire on #5 cylinder. We didn't even get to the 4th code. $ exhaust codes? C'mon man! That is why I get frustrated.

My apologies and thank you for the reply. Having been on forums for years (mainly diesel and bikes) I know how frustrating inept posters can be with lack of info or only hearing what they want to hear. It was a complete slip up on my fault due to the fact I knew I was in the 2015 forum but forgot about the bigger motor and 8 speeds on some. I assumed it was the DI. I just bought it used last weekend from the dealer. It was there loaner vehicle. 15k on it. Still looks and smells new. I will take it in this week and have them listen to it. This is the first vehicle I've cared about the warranty on and intend to keep. Having a magnaflow muffler put in was stressful enough, like I said I've never cared about a warranty before or had anything worked on at a dealer. Thanks again for the reply sir, good day to you as well!
