Some markets have indeed experienced problems with the Nissan CVT transmission as fitted to many of the brand’s vehicles. It doesn’t seem as widespread in Australia, but some faults have been identified.

That main problems seem to be overheated CVTs which can cause juddering when driving and premature wear inside the transmission. According to some in the trade, the fault is caused by a problem with the way the transmission fluid is cooled, and when it gets too hot it can cause warping of the metal parts inside the unit.

Ultimately, the solution would be to fit an external oil cooler for the transmission fluid, but otherwise, a close eye on the level of transmission fluid and correct servicing is the key to making the CVT last.

The default purchase for somebody looking for a mid-sized hybrid SUV is the Toyota RAV4 Hybrid. But if that’s too big, there’s the Toyota Yaris Cross Hybrid, C-HR Hybrid and even the Corolla Cross Hybrid which sounds like the marketplace is getting crowded but is really just a reflection of the appetite right now for cars like these. And that’s the catch; the waiting times for a brand-new example of some of these cars is out to many months and even years. So your plan to shop second-hand makes plenty of sense, but don’t expect any bargains in a market currently being dominated by lots of demand and less supply.

Beyond the Toyota brand (which has been doing hybrids longer than just about anybody else) there’s also the Mazda CX-30, Subaru XV Hybrid, Haval Jolion Hybrid, Kia Niro, Subaru Forester Hybrid, Nissan Qashqai e-Power, MG HS, Honda HR-V e and more. For something a bit bigger, try the Kia Sorento or Hyundai Santa Fe hybrids. There are others out there, too, that are probably bigger or more expensive than you need, but it's very much a growing scene in the Australian marketplace.

It’s important to give Nissan (or any other manufacturer) the opportunity to put things right. While ever that process is ongoing, you need to be patient and allow Nissan to try to find a fix. Your car is still covered by the manufacturer’s new-car warranty, so that’s the process by which it should be tackled.

If Nissan were to give up on the problem (and you) then you’d have cause to seek recourse according to Australian Consumer Law. I’d also be talking to Nissan Australia’s customer service division to see what else can be done.
