2024 Tahoe - 10L80 issue

[tom3]

I've noticed some vibration in our '19 now in V4 mode. Before this I couldn't know if it was cruising in 4 or 8 cyl. without looking at the DIC. I'm now at 30K miles, not looking too good on the long run I'm guessing.

At a minimum, find some way to disable Engine Half@$$ ...
Your engine and transmission will last longer for it.

The Range Disabler fixed the vibration.

I have a 2024 Yukon Denali 6.2 liter and get vibrations on the highway when cruising (4 cylinder) Also is pronounced when going around turns on the highway. just had road force balance and only5500 miles. dealership says they cant feel it but they never took it on the highway. $87k. not happy

The Range device when on my 2024 at 275 miles and not looking back.

I think once the vehicle ages and gets miles on it, small variation of the DFM start to be felt. Bushings are hardening, wear is happening, performance is slightly deteriorating and all these factors along with more butt time in the seat and you may notice things that were unclear before. Even the exhaust hangers hardening can all the exhaust system to vibrate and become noticeable.

Make sure you get tires rotated if this has not been done yet, do about every 6000 miles. While road force balancing can be a good thing, these balancers often do not pick up bent wheels. Only if the tire tech is good and paying attention looking for a bent wheel and knows what a bent wheel looks like.

As mentioned, put the transmission in 9th manually and this should keep the DFM from operating and you could maybe feel the difference.

You really don't feel the vibrations when the engine is operating in a rolling 4/5/6/7/8 cylinder operation with DFM. It's only when it gets down to 3 cylinder operation at very light cruise that it's noticeable. I've had a few come through with that complaint. It is what it is unless you run around in L9 or buy a Range.
