None on mine in the first 3,000 miles. Have done about 1,000 miles of towing.
A couple observations: A bigger one is the gas mileage isn't as good as the EPA estimates. In my other vehicles, I usually better the estimates, only have matched them on the highway during the break in period, not exceeding 55mph. Now averaging about 18.5 hwy, 15 city.
The other observation is how slow the MyLink system responds to touch commands.
Other than those things, that are minor to me, we love our new Tahoe.

Great thank you its just sometimes with new cars u dont know there is a problem until you speak to other ppl about it.
Stick your head near your driver side front wheel with the car running and listen to the noise of the serpentine belt system. Almost sounds like a muffled diesel. I just spent 70K on a 2015LTZ and Im not happy. The dealer let me listen to another 2015 and it sounded the same. Please someone tell me their 2015 is as quiet as their previous Tahoe or do the test and let me know your Tahoe is "quiet". Thanks.

No noises on mine. Very quiet inside, outside, driving, windows up or down.
Noise on 2015
My dealer says "all the 2015 tahoes have the same noise"
Can't here it inside. I listened to 5 others since my first post and all had the same noise. Inside the vehicle is very quiet. I think if you listen again you will here it. Maybe you think it's normal. I traded another hoe and it was quiet like a RR. hehe! One salesman said the noise on the truck line was more noticeable.

Linty, does it bother you? Will you ask your dealer about it of just accept it and drive a noisy luxury SUV ? Maybe it's me but my 2009 was the best SUV I have owned. That's why I went for 70k on a new one and Im not happy. Would not recommend to a friend at this point.

I still don't hear what you're describing. It's very quiet outside, driving or just revving the engine parked, outside the vehicle.

Yes, the new direct injection motors make a noticeable clicking sound. The sound can be similar to excessive valvetrain noise. The reason for the noise is that the direct injection system is a very high pressure system. Basically, it is a high pressure system similar to those found on modern diesel motors (the diesel injectors all make the same clicking noise).My truck is in for service now, I called and asked about the clicky noisey sound, I was told its the new injection system they started using in 2014
I do not notice any excessive noise from the serpentine belt on ours.
So far, our only issue has been a failed GPS antenna. The frustrating part about this is that parts aren't available for the repair. Parts are still on backorder.... This has been an issue with a lot of the 2015 Tahoes, Escalades, and Yukons...
Yesterday evening, we were notified that there is a recall for a wiring harness in the console. Hopefully, the parts are available for this one...

Noise 2015
Thanks for the posts. I mentioned serpentine belt for lack of another description. What you are describing is exactly the sound. Almost a really really quiet diesel. I pulled up next to a 2015 Escalade today in a parking lot that was running. I have no idea what motor the Caddy uses but it was making was a similar noise.

The new Caddy uses the same engine technology. The new Corvette engines make similar sounds. Any new direct injection GM engine will make similar noises. Different vehicles will sound differently due to differences in sheet metal and soundproofing materials.
Noise is also very subjective for folks. Most folks don't notice the ticking noise of our Tahoe. To them, it is a very quiet vehicle, both inside and out. To me, I notice it immediately. Fellow gearheads notice it right away as well. Unless you can listen to the other vehicle, it is hard to say for that his doesn't have the same noise.

:drool2::drool2:I am a gearhead and Corvette owner. (08 Z06)
We have a modified 01 Coupe. Currently trying to figure out a way to get into a new Stingray with my current wallet. Trying to be patient until we can save up some more. It didn't help any when a friend tossed me the key fob to his new ZO6 with ZO7 package and said "fire it up..."
