Range told me the Pulsar LT wasn’t working on the ‘21+ yet. Did you get it to work on yours?

I do not have a 21+. I just got the info from forum member slowride77. May want to message him and see what he has to say.

I'm totally new, and just pulling this out of thin air, but it sounds like active noise cancellation. I'm not sure if yours has it, but it could literally be your sound system generating that noise. Could be malfunctioning or it could be working properly and you are just sensitive. Just a thought.

I am surely very sensitive in term of accoustics/noises. But it starts only when the vehicle is moving. I don’t know how the ANC is working but even at speeds like 3mph I can hear it. When I stop it’s gone… go figure.

 

[Zoni]

That would be at higher speed. This one stops at 65mph.

any Change if you fold the mirrors in?

 

[Zoni]

Try folding in mirrors in to see if buffeting stops

At 3mph? Lol

My 2021 Tahoe High Country is not near as quiet in the cabin as I hoped it would be?? I get lots of “rumbling” even at low speeds. The cuts in the payment seem to be amplified? It feels like it has 100 lbs of air in tires, but it doesn’t? Bridgestone tires and PSI is 34-35.

Anyone figured out what can be done to quiet down the ride?? Thanks in advance.

Any updates , i have a 22 Denali, same issues, I get headaches driving the thing, I can’t figure out where it’s coming from, also has tons of road noise, my 2020 ram rides way nicer and much quieter, sure makes me mad, for $85,000 it should be much nicer.

I hear the "chopper" noise any time the rear windows are down and front windows up. I think it's an air pressure issue and not mechanical . I hear it in the Blazer or the Silverado. If I crack the front window the air pressure is equalized and the beating in my ears is gone . That noise hurts my ears yet my wife and daughter hear nothing. It's the fault of the dogs who "need" the rear windows down .

im having the same issue in my 21 suburban LT, booming noise if you go over the slightest bump, seems to stop of over 65 MPG, anything over 12 MPG to 55MPH its pretty bad.

All wheels have been road-forced balanced, even different wheels and tires issue persists. It's super annoying as its like being in a subwoofer. Seems to be worst if AC is running at full blast.

Ever walk into one of those cheap metal sheds when it is windy out? There is a lot of thin sheetmetal on these beasts, especially the roof. You have to wonder if any welds or adhesives are missing in the support structure that these things tend to boom like crazy. Did they ever figure out what was going on with the previous Gen's?

At any given speed when it’s making the noise, if you give it enough throttle to trigger a downshift (and AFM or whatever it’s called now, shuts off), does the noise change? I can faintly
Detect when our 5.3 is running on less cylinders at speeds in the 25-45 range, and it has a slight harmonic like a helicopter, but it doesn’t bother me at all.
