Hyundai Sedan Range

Depending on the amount of fumes visible (it’s not actually steam) this could be a small or large problem. Here’s how that works: A small amount of white fumes from the oil filler cap is not so bad, but what you don’t want to see are gales of the stuff blowing out when you remove the cap.

These fumes are caused by pressure from the combustion process in the cylinders finding their way into the crankcase. As an engine wears, more and more pressure can find its way into the crankcase, increasing the fumes. When the fumes increase, this is a clue that your piston rings (among other things) are becoming worn over time and kilometres.

But you could also be looking at a car with a faulty PCV valve. This valve has the job of removing the fumes and sending them back through the engine to be burnt a second time. But if the valve is faulty, the engine won’t be vented sufficiently and the fumes suddenly become visible again. So, have the car checked out at a workshop who will be able to perform a compression test to tell whether the engine is in good internal condition or not, as well as check the PCV valve for correct operation, If the problem is the latter, it’s an easy, cheap fix.

Your budget puts you into some good EVs with decent range including the BYD Seal, Cupra Born, Hyundai Ioniq 5, Polestar 2 (just outside your budget), Tesla Model 3 and others.

Resale value is the big unknown at the moment with many used-car buyers wary of the potential costs of replacing the EV battery sometime in the future.

The future-proofing thing is debatable, too, and experts reckon EV technology is still in its infancy and has a long way to go. If that’s the case, then today’s EVs might seem like Model T Fords in the near future. It all remains to be seen and rests partly on the willingness of the Australian government to get serious about the EV infrastructure necessary for the tech to become viable for more people.

Car makers will sometimes help out with such problems provided the car has been serviced correctly and not abused throughout its life. I agree that 40,000km is not a reasonable expectation for a modern automatic transmission, so I’d be contacting Hyundai Australia’s customer service division to see if anything can be done. Experience tells me that Hyundai takes its obligations in this area pretty seriously, so you may be offered some help with the cost of repairs.

You could also have the transmission inspected to see what went wrong (your state motoring club is a good place to start for independent inspections like this one) as this information might be very useful if you decide to take the matter further. The ACCC would be the final step in this process, and Australian Consumer Law deals with what is fit for purpose and what is not.
