Hyundai Sedan Range

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.

It’s very possible that this is a problem with the brake’s booster system. To give the braking system extra oomph, it uses a vacuum operated booster unit that multiplies the force in your leg. The vacuum comes from the engine’s intake system. If this booster develops a vacuum leak, it can allow excess air into the engine’s intake manifold. This extra air messes up the air-fuel mixture and the engine can start to rev up.

The brake booster is the first place a mechanic will check when presented with this problem.
