i just had the pump and module replaced under warranty for my 2017 qv. parts took 2 months to arrive. drives great as far as i can tell. will try extended wfo runs this weekend when i can find some open roads.
stay on the dealer and communicate alfa usa...they worked hard to help me but the supply chain issues are real and the parts are being changed on many cars currently thus the waits are quite long. my qv is just a toy and it is usually garaged and covered so it was not too big an issue waiting. i understand not all will feel similarly.
this response is posted on another thread as well. just wanted to be sure the op saw it.
