Isuzu MU-X Series II RWD 3.0L Diesel LS-U (2017-2020) Questions & Answers

It's obvious that Isuzu dealers know about the fault but are unwilling to do anything. These are apparently fitted by a well known company in Melbourne.
I presented to my dealer saying that although I could hear the parking sensor alarm when standing at the rear with the door open, when in the driver's seat, I could not hear it. This to meant to me that it was not fit for purpose!!! Pressing the workshop manager to do something he maintained that there was nothing that could be done! I asked him to remove the cup holder panel in the L/H rear where the sound was coming from which after some prying he did remove it, showing all the components. I thanked him for that and went on my way. the next day I had a closer look at the installation and noticed that the piezo had been glued into by it's metal drum reducing it's volume! I fitted a slightly larger piezo ( 95db under $10) and mounted it on a small bracket & attached it to a M6 hole just under where the original one was glued. Put the cover back on and it now works perfectly!!!! NO THANKS TO ISUZU UTE
