Using 5-7 litres per 15,000 km is certainly not normal. Like you I would not expect to have to add oil between services. Ramp up you anger and demand the engine on your car be rebuilt or replaced.
It's not that unusual for a coil to fail, but to repeatedly fail like that is unusual and I would be looking for issues other than the coil. The most common issue is the crank angle sensor; it would be worth making sure all is well with that.
We have heard of reports of stretched timing chains on the V6 Holden engine. We are aware that Holden has replaced some timing chains under warranty; so lodge a claim with Holden requesting they pay for the cost of the replacement.
We have had a few reports of oil burning with the Holden V6, and it would seem yours is another one. To start with run a check of the consumption by topping it up and then checking it weekly for a period, say 5000 km, and measure how much oil has been used. If it is high, as you suspect, take your findings to your dealer and ask for some action to be taken to fix it.
The main reason is the lack of repeater stations we have, if we had more the reception would be better. Poor receptions can also be caused by interference from overhead power lines, tramlines and the like that you get in the city and inner suburbs. It can be usually improved by fitting an aftermarket amplified antenna, but the VE already has an amplified antenna and is one that isn't often affected. You could fit a better quality amplified antenna, but that would entail fitting another radio and it's starting to get expensive. You could also look at getting a digital radio module and connecting that to your radio through the auxiliary connection, which would improve your AM reception and give you digital radio at the same time.
We contacted Holden about your concerns and received the following response from its spokesman John Taylor. John told us that there was no direct relationship between oil consumption and engine pinging. He went on to say that if there is a pinging condition affecting your car then the Holden dealer could address it and they would be happy to put you in touch with one of the company's Customer Assistance Service representatives to do that. Should you want this to happen get back to us and we will advise Holden to set that process in motion. As to your assertion that "Holden has relaxed the tolerances on the pistons in the late model Commodores (SIDI engines), allowing oil to get past and gum up the motor with carbon", John denied that was the case, saying that Holden has not 'relaxed' any tolerances of pistons/rings that could then cause the engine to 'gum up'. Again he made the offer of putting you in touch with CAS to discuss your concerns.
There's no widespread issue with the transmission, but like everything they can have troubles. It's impossible to say if the new transmission will give you any trouble, consult your crystal ball for that one. Fitting an external cooler can help if the cause of the transmission failure was related to overheating. In theory the transmission was filled-for-life at the factory and doesn't need servicing, but auto transmission experts will tell you it's wise to have the transmission regularly serviced, possibly once a year, particularly if you are towing.
If you feel the problem was caused by the mechanic you need to go back to him and negotiate a settlement that satisfies your complaint. It would be wise to get another opinion before approaching the mechanic, so you're sure of your ground.
