We haven't had any other complaints of this vibration, and we'd ask anyone else who has to contact us. The first things you look at when you have a vibration like this are wheel and tyre balance and driveshaft balance. Have the dealer check these things, so you know where you are in terms of the basics before initiating any other checks.
The claimed fuel economy figure is a result of a standard test that all carmakers have to conduct. It's intended to give buyers a guide they can use to compare cars when choosing which to buy. The figure will differ in real world due to all the factors that can influence fuel economy in everyday driving. I would persist with it, you could find it will come down with more miles on it, and you could look at your driving habits and see if you can make any changes that might cut the fuel useage.
While oils are better now than they once were, so to are the demands placed on them. Regular oil changes are wise to keep your car ticking over at it should, don't hesitate to do the servicing.
I agree that a three-year-old car should be running like a dream. Faulty electronics, as it would seem yours has, can be a curse, and hard to fix. If the problems don't occur when the mechanic is there to observe them they are working in the dark. At least the dealer appears to be continuing to work on your car.
Holden has an obligation to fix your car if it has a problem, and while you might disagree it would seem that they have attempted to fix it. They fitted a short motor, then offered to fit another one, and they have done an oil consumption test to determine if it does have an oil consumption issue. Most Holden V6s do have an issue with oil consumption, so I wouldn't be surprised if yours does as well, but it comes down to how much oil it uses as to whether it has a problem. If you doubt the results of the oil consumption tests, do your own.
It needs to go to a mechanic who can properly diagnose it. It sounds like it could be a sensor problem, which should show up on a diagnostic check.
Wheel alignment is clearly not covered by the warranty, so you won't get Holden to show any interest in your claim for new tyres. Remember that it was the dealer who did the servicing work on your car, not Holden itself, so if you think the dealer was negligent in not discovering that the wheel alignment was not correct you should pursue your case for tyres with them.
It would appear that the vibration is coming from the driveline, and the clutch being part of the driveline could well be source of the problem. It's worth getting it checked.
At that speed it's likely to be either tyre or driveline imbalance, but you need an experienced mechanic to test drive the car with you. Talk to your dealer and ask for a mechanic to come with you while you demonstrate the problem.
