You’re right, Michael. Toyota Australia tells me that the current model Camry is Euro 6 certified (for emissions). Because 91 RON fuel won't support Toyota's Euro 6  technology, 95 RON is recommended. Since most readily available E10 fuel is rated at 94RON, Toyota doesn't recommend that for the Camry, either.

However, even with the extra cost of the 95RON fuel, the Camry Hybrid's official combined fuel consumption number of 4.2 litres per 100km suggests it would still be cheaper to run than many other cars using 91RON.

It sounds as though the engine’s idle-speed is set a little too low, and that’s making the engine feel lumpy (because it’s almost stalling). Having the transmission in Drive is adding a little load to the equation, slowing the engine even further. There are many things that can cause this, including a stepper-motor that is faulty and not controlling the idle properly.

The best advice is to have the car scanned for a hardware or sensor fault and proceed from there. But first, try this: With the engine idling and in Drive (and the vibration present) turn off the air-conditioning. If the vibration goes away, it could be that the electronics that detect the extra drag of the air-conditioner and automatically bump up the idle, aren’t working properly.

The horn-beep when you lock the car should be able to be turned off via the car settings menu on the main infotainment screen. You need to the find the menu that gets you into those settings and turn off the horn beep function. Many car-owners hate this feature (and so do their neighbours) but disabling it is a fairly simple process that should also be outlined in your owner's manual.

The radio with a mind of its own is another issue altogether and has been around long enough to annoy a couple of generations of LDV owners now. Radios that turn themselves to full volume every time the car is switched on, poor reverse-camera clarity and Bluetooth systems that simply refuse to recognise some phones have all been flagged by owners. But since the car is still under warranty, you should take this up with your LDV dealer. There may be a factory reflash that will return the radio to an obedient state. Perhaps the stereo system is turning itself on automatically as it searches for a connected phone. Some LDV owners have resorted to aftermarket head units to fix these problems, but hopefully LDV has engineered a fix for these later-model vehicles.

I'll take a punt here and suggest that your car is the turbo-diesel variant with the six-speed dual-clutch transmission. The dual-clutch unit is vastly more problematic than a conventional automatic transmission and has given many manufacturers (Ford and VW being two of the main ones) all sorts of consumer grief over the years.

The unit in your car is a wet-clutch design which is much more robust than the cheaper-to-make dry-clutch type, but has still been known to fail. (The dry-clutch units on Ford's Focus, Fiesta and Ecosport models cost Ford millions in fines when they began failing at low mileages and the ACCC stepped in.) That said, the wet-clutch units have also experienced problems, but before you scrap the car or shell out $15,000 for a new gearbox (which sounds like an ambit claim in the first place) have it checked out by a specialist. In many cases, jerky progress like you're experiencing can be caused by the transmission's control module or even a faulty speed sensor inside the unit, rather than the actual transmission hardware. If that's the case, it may be more economical to repair the car.

Beyond that, I totally agree that less than 100,000km is not an acceptable lifespan for a major component such as a car's transmission.
