Newbie here, hopefully following the rules correctly..
I have a 2015 Triton GLXR Turbo Diesel (done 118,000km) that I purchased in 2019 from a dealer. I have had it regularly serviced through authorised mitsubishi mechanics since purchasing, 5-year warranty expired in 2020, my last service was in November 2021.
I was driving on the weekend and when accelerating between 0-60km/hr it was making a not-very-loud banging noise, so I started to head back home. I pulled up at the traffic lights and the car just stopped, it wouldn't start again, there were no warning lights prior to this and then when trying to turn it on they all lit up.
A helpful guy managed to help push it out of the road (such a joy with a sleeping toddler and being pregnant!) and I called for a tow. Towie arrived and when he turned it on it had the fuel filter light on. Mechanic checked it on a Monday and said he can't get it to start and it seems like the engine has seized. Mechanic said he has done some investigation and fuel looks fine and same with oil, so he has no idea what has caused it. Has told me there's an engine over east he can get for $7k and roughly another $5-7k to install it. I feel like he's pushing me to do this, but that may be as more investigation is more cost for me..?
I'm just wondering if I should tow it to another mechanic for a second opinion? Seems odd to me that a well-serviced engine would just die without any warning and it also being so young, I would've thought a $26k car would get more out of it. I'm not sure why an engine would just seize? To be clear, I don't off-road, mainly drive my sleeping toddler around and occasionally drive it to work, so no abnormal or high impact driving.
I've looked into my rights, seems like I might have some through Australian Consumer Law against the dealer, as a major failure, which I might look at but first would need to determine what the issue is.
Can anyone shed some light or give opinions on what you would do in this scenario? I'm at a loss and devastated that the car has just failed.
