Just picked up at4x and was wondering if there's anything different with the refresh amp vs older models. I'm planning on installing aftermarket subwoofer from old truck and I have the anc delete cable and harness that plugs into Bose amp for signal. I believe it says 2014 and up but just want to make sure before I remove rear seat. I had a 2018 Silverado with Bose but the new truck has more speakers. 12 in the new one. I only count 11. Is there a sub in console like the 2018?

  Hasn't come up in the 3 gm forums I follow. And only gm knows the frequency of failure of that part. LMG, you want a recall so it's replaced for free...

  You need a better code reader/scanner. You are missing codes. Did the dealer give you a copy of the SAVI scan from that visit? If the fluid hasn't been changed, change it. Shudder will likely go away.
- Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

  TLDR to my other post... Hard. Pass. Too many what ifs. Are you set on a 3.0 Duramax? Have you considered anything not GM just in case? If you don't have to have a pickup, lots of other options for $27,000 out there.
