Hello, I purchased a left over 2018 Yukon from my local dealer. When I accelerate I hear what I call a ping noise or rattle coming from the engine. Reminds me of the old days when I was young and needed a higher octane fuel for a muscle car. I brought it to the dealer and they said they could not make the noise, they didn't try very hard. Just thought I would reach out and see if anybody else is experiencing this issue.

Welcome to the forum.

Some more info about your Yukon might help.

What size engine?
How many miles?
Flexfuel?
What gas are you using? Octane/alcohol content.

Can you get some video that records the sound and post it?

What happens when you go from the lower octane to the mid range octane or have you not tried it? I own an 02 and run the mid range with absolutely no problems. What range octane fuel does the owner's manual call for?

92 octane is recommended for the 6.2 (not required) but you might try it on the next fill up and see if the pinging goes away

Also concur that the issue may be the fact that you are using regular gas. Try some 93 octane next time your tank is mostly empty.

Is the noise speed dependent? RPM dependent? Or just when you are accelerating?

Do you hear the noise if you are in neutral and rev your engine?

I’m with the others on trying a higher octane fuel as well.

Also, make sure you are running top tier gasoline through your tank — which is recommended by GM. Go to toptiergas.com for a list of brands carrying top tier gas and diesel.
