When you purchase a car from a dealer or, in some cases, an auctioneer (grays, pickles etc) you are eligible for a statutory warranty in many cases.
https://www.qld.gov.au/law/laws-regulated-industries-and-acc…
This warranty covers most mechanical defects.
"A statutory warranty will cover most defects. The vehicle has a defect if a part:
does not do what it is supposed to do
has worn out so much that it no longer works.
A statutory warranty does not cover defects in:
tyres or tyre tubes, batteries, fitted airbags or radiator hoses
lights (other than a warning light or a turn indicator light used as a hazard light)
an installed radio, tape recorder or CD player
an aerial, spark plug, wiper rubber, distributor point, oil or oil filter, heater hose, fuel or air filter
paintwork or upholstery
air conditioning ('class B' statutory warranties only).
Statutory warranty also doesn’t cover:
accidental damage due to the buyer’s own misuse or negligence
anything the buyer fitted to the vehicle after the time of sale."
The dealer will try to bullshit to you about it not covering wear and tear, but it does. If the ball joints are worn out, it's covered, if there are oil leaks, it's covered, if your exhaust has a hole in it, its covered, if your gearbox isnt functioning EXACTLY like it should, its covered. The legislation lists very few circumstances where something won't be covered.
If your dealer does try to screw you out of statutory warranty repairs you CAN search for previously judged QCAT (small claims court) cases and use those as evidence to push your case. When they know they won't win in QCAT they will, most of the time, give in to what YOU ARE LEGALLY ENTITLED TO. Make it clear that you will take it that far.
Don't be stupid, or unreasonable. You're not getting a brand new 2024 car to replace the 10 year old lemon you got lumped with, but also don't be afraid to push for your lawfull entitlements under your statutory warranty.
This comes from personal experience.. I bought a car without a mechanical inspection (always get a mechanical inspection). My car ended up needing a good $6000 in repairs, including a replacement gearbox. Yes, I had to fight for it, for nothing more than I was legally entitled. 8 weeks so far and nearly have the car back, but they've caved on everything.
Don't blame the victim. A dealer has to give a statutory warranty so if they choose to sell a car that they know is faulty it's a risk that THEY take. Buyers shouldnt have to foot the bill for a bad trade in the dealer took, then decided to act shady on by selling it as is… but still, get a mechanical inspection if for no other reason that saving yourself the hassle.
Queue the dealers crying about the law screwing them etc.
Ok
