Ok I'm back and would like to update everyone. Holden have had the ss three times to try and fix the coolant loss issue. I have also taken it a reputable mechanic who test drove it and gave me some crazy reason why I smell coolant all the time.
Tuesday night before I leave work I check the overflow. Empty. Check the radiator. Coolant sitting just on top of the fins inside. Ring Holden Wednesday and they book it in for Thursday for the coolant issue and for it to get serviced. I stop in there and pick up a bottle of dexcool and it takes 2 litres.
Take it to Holden on Thursday, they need to order a heater hose and it stays there overnight. Pick the car up on Friday, noticed they have washed it and go straight to work.
Saturday morning I walk outside and lose my ****. It would appear they have taken it through an automatic car wash. The car that only I wash, by hand, that takes me forever, with paint that still looked brand new now has buff/swirls all over it. Every single panel. It has a dint on the upper passenger side quard and a deep scratch around the same area.
I pop the bonnet. The radiator has no coolant and the bottom hose is flat, has sucked in. I cannot find a brand new hose and one looks like it has been rolled in orange dirt. To top it off I just went outside and it won't unlock, not even with the spare key
