Toyota Aurion Engine Problems
Toyota Aurion 2009: Does it have a timing belt that requires replacement?
The Aurion has the V6 engine, which has a timing chain, so there’s no call for routine replacement as there would be if it had a belt.
Commodore or Aurion for durability and everyday driving?
I think you’re comparing apples with oranges in comparing these two cars. But to try and give you a guide I would say the build quality of the Aurion is a little better than that of the SS. I would also say the Aurion’s V6 engine is of a higher quality and standard than the SS’s V8, and would use less fuel, but I would say that both are equally drivable and practical in city traffic. My feeling is that the SS is an emotional purchase, the Aurion a safe one.
Toyota Aurion 2007: Engine rattle
There is a problem with the VVTi hubs on the Aurion that causes the rattle you can hear. The problem for you is that the car is seven years old and long past the end of the warranty period. We have heard of other cases in which Toyota has paid for part of the cost of the repairs, so I would suggest that you approach Toyota for a similar deal.

The replacement hose addressed the problem, so it shouldn't happen again, but it's not possible to say that it won't. If you feel uncomfortable about it you could get the later oil pipe fitted to your car.

If it is suspected that the rattle is coming from the engine then inspecting it, and flushing the system could be wise.
