Looking for possible assistance with the vibration issue in my wife's Tahoe. It has this vibration at very distinct speeds., 25-29, 45-49, 59, and more. It is very noticeable when accelerating smoothly, non aggressively. The vibration is so prevalent that it is felt in the seat and throughout the steering wheel. It has been to the shop twice, the last time I took the mechanic with me and he witnessed the vibration at the low speed, we didn't get on the highway at higher speeds. I left it with him for a day, he states its the DFM switching back and forth with cylinder deactivation. Seems odd to me that it does it a those exact speeds and its constant when at those speeds. I cannot recall this truck doing this when I picked it up upon purchase nor a few weeks after owning it. My next test is to set the cruise while its vibrating on a smooth road and see if it changes if the truck accelerates going up hill, if its the DFM, it should deactivate due to load and all cylinders should fire and vibration should stop. If it doesn't stop, I believe it would be something else. Your thoughts? I do like the truck, but the amount of money this truck cost, I should not be dealing with vibration issues. Thanks in advance.

Hi have you figured out what’s going on with your Tahoe? My wife’s 2022 high country does the same thing and a dealer said that just a Tahoe. I have owned 4 Tahoe in my life and loved them! But this one drives me crazy, I personally like driving my ram 2500 better it’s quieter and when there’s a smooth road it’s smooth. The high makes every road ruff! Let me know please

Bone, yes I took it too a different dealer and the tech that rode with me owns a Tahoe and he noticed it right away...after about a week of diagnosis turns out to be a bad torque converter. One on order but back ordered. I would go back to that dealer and request to drive a new one to prove they don't just do that.

Curious to know if replacing the torque converter fixed the vibration issue?

No, it didn't solve the issue. It still does it. Dealer seems to think its the computer trying to figure out what gear to shift into, normal for the new transmissions. I personally believe its the transmission or maybe the internal pump. When its cold, you feel it but not as bad, once it warms up, you feel it more. When I tow a trailer, I can really feel it during acceleration. I just need to go to a dealership and drive another to prove its not all Tahoes. I have had 3 previous model years, never had a vibration problem.

Thank you. I have a 2021 Yukon at4 under 20,000 miles and have just started noticing this “vibration.” Have not had a Tahoe or Yukon in the past so wasn’t sure if this was normal.
