Good luck then. I've also had 2 Outback units in the past that lasted years. This is the first one that hasn't, by a long way. The only differences I can see between this one and mine are 1) the ignition knob colour, 2) the doors on the front open down instead like a normal side hinged door, 3) I have 4 locking swivel wheels and this has 2 fixed ones and 4) the grills/griddle are 50% each whereas mine is 75% grill 25% griddle.
It is a shame but they no longer seem to have the quality that they used to have. I can remember when they first came to UK and they were superb. Mainly just Chinese built tat now. "Cast iron burners superior to Stainless" utter tosh, just cost cutting. Might be alright in a dry climate, but not in UK,
As stated above this is the 2017 model so fingers crossed it is an updated/revised model. Also if it is only 2 years old yours is still under warranty. Might be worth getting in touch with them? Revoo gives it 8.5 out of 10 so, for me, it is worth a go. With barbecues I have found that 'buy cheap, buy twice' is a fair motto. My last Outback barbecue lasted 10 years so I have every faith that this one will last too - but I might be wrong...
I bought one of these 2 years ago. absolute rubbish. burners are corroding as they are cast iron and foster up yellow gas, the ignition now only works on the side burner, the shiny rings between the gas control knobs and the main BBQ body are rusting. And it's an absolute **** to clean the frame where the food grills sit.... But it's up to you ;)
