Got the same message. They replaced the positive battery cable. Message went away a week later.

2017 Silverado LT CC SB 5.3L 6-speed 3.42 68+ mph 4000 miles So my Vibration wasn't as bad as some of the videos that I have seen posted where the water in the cup was shaking all over the place. It also did not make any audible shaking sounds, but I could feel it. I noticed it on my first long trip with the truck and thought it might be a bad balance on the tire or something. I took it to the local chevy dealer and they ran the picoscope on it. They confirmed that it did have a vibration. It had a 15.3 mg Tire 1 vibration @ 14.1hz. They replaced the steering gear bushings and said that I had a defective Passive Exhaust Valve and installed a new exhaust from the Cat back. They ran the picoscope again and the amplitude was down from 15.3mg to ~3.5mg at 14.0hz. I have only had one short highway trip and it feels a little better. I will report back when I get a good run at highway speeds. Thanks to everyone who has contributed to this thread.

Hoping to trade chrome for paint in Massachusetts/NH. Looking for summit white bumpers, grille and lights. 2017 Silverado LT 1500.

Who did this work? GM?

What tires did you have previously? and what did they put on? Thanks

Just did this on my 17 CC 5.3. I am a believer. The truck is so much nicer to drive now. THANKS to the OP!

Is this something that anyone with this model should get done? I can't tell if I have the issue or if it is just in my head because of this thread!?!
