A poor earth is often the cause of this sort of misbehaviour and it’s a good place to start looking. Check the earthing points in the engine bay and around the area where the tail-lights are earthed in the cargo area.

You might need to lift some carpet or trim pieces, but when you find the earth points, make sure they’re tight and clean and not covered in corrosion. Don’t forget to check the tightness and cleanliness of the battery terminals, too.

Beyond that, these symptoms point to a problem with the car’s body computer which controls all these functions and many more.

When this computer starts to die, all sorts of weird and random flaws can occur. But try this first: Disconnect the battery of the car and let it sit overnight. Reconnect it next morning and keep a close eye on what happens. Sometimes this simple trick will reboot the body computer and normal service will be resumed. Best of all it’s free.

It really doesn’t matter how fast you’re driving when a timing chain or timing belt breaks. If the engine is an interference design, then this failure has possibly turned the rest of the engine to junk. That’s because the valves and pistons have tried to occupy the same space at the same time, and widespread internal damage is the usually outcome.

From what I can gather, the V6 engine in your car is indeed an interference design, so the damage is possibly terminal. You could remove the cylinder head(s) to check, but if the engine has locked up, there’s a fair chance you’ll need to either rebuild the engine or replace it with a different one. You may also find that the cost of these repairs will be greater than the market value of the vehicle itself. At that point, you need to decide whether to repair it or start again with a new vehicle.

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.
