If the problem is getting worse, then there's clearly something deteriorating with either the doors themselves or the rubber seals that keep the air and water out. You could start by visually inspecting the rubber seals. Is there any obvious damage (such as a seat-belt buckle been left hanging out when the door was slammed shut)? Are there any witness marks or visible fretting on the paintwork from any component. Even a stray leaf caught between the door and the rubber can cause a leak, so give the area a good clean and see if that helps.

The door hinges could also be at fault, but I'd be a bit surprised if a car as new as this one has worn hinges already. In the bad old days, this problem was usually fixed by grabbing the window frame part of the door and bending it in slightly to achieve a better seal. That probably won't help you, but keep in mind the car is still under warranty, so make it Haval's problem.

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.
