Used Holden Commodore review: 2006-2009
By Graham Smith · 12 Oct 2012
The all-new VE Commodore was heralded as the car that would keep Holden ahead of the pack when it was released in 2006.Holden invested more than it had ever done before in developing the VE and was looking to the new car to maintain its premier position in the market. Sadly for Holden, and Ford, the market has undergone a seismic shift in the last year or so and big cars, like the Commodore and the Falcon, are now on the brink of extinction.While that might be the modern reality cars like the VE Commodore can still represent good value for money if you prize might and power. The attractive sedan and wagon are roomy, comfortable, refined and well equipped, with lots of space to carry the family and the gear a family takes when they hit the road.Holden offered a choice of V6s, there were two versions offering different output, a big beefy V8, and an option of a dual-fuel V6 to save a few bucks at the servo. With 180 kW and 330 Nm the base V6 was plenty powerful enough for anyone, but for those who felt they needed more there was the 195 kW version available in the sporty SV6. For even more the option of a V8 was there in the SS.Transmission options varied between models, starting with a four- speed auto and ending with a six-speed self-shifter. There was also a manual gearbox although that wasn't a big seller, at least in the cooking models. On the road, the VE handled well, the ride was well controlled and comfortable, and performance was brisk no matter the engine. Fuel consumption was a concern, however, and an average ranging between 10 and 14 L/100 km was disappointing.While the VE was generally well built and solid there are issues that affect it and these make it a questionable used car purchase. It's been well documented that the previous 5.7-litre V8 was troublesome, it rattled on start-up and used oil at an alarming rate; the troubles haven't gone away with the introduction of the new 6.0-litre engine.Owners still report rattling noises and there are also reports of high oil consumption. Unfortunately it seems the 3.6-litre V6 also has some issues. One member of the trade recently contacted us to tell us about his experience with the engine, which he says can become clogged with sludge between the 15,000 km service intervals with the result that it can be severely damaged to the point of needing to be rebuilt.All carmakers have been stretching service intervals with the object of saving the owner a few bucks on servicing costs, but in this case it would appear that the interval is too extreme and anyone with a Commodore V6 should consider having their cars serviced at 10,000 km intervals. The V6 also consumes oil and there appears to be no fix from Holden, and listen for timing chain rattle, as they wear and become noisy.We have heard of timing chains breaking. Anyone thinking of buying a VE V6 would be well advised to have a trusted mechanic give it the once over. Other areas of concern are worn suspension bushes, listen for clunking and banging from the suspension, and electrical gremlins, check that all systems are working.Appealing on the surface, but can be troublesome and should be approached with caution.

No matter how schmick the car looks, though, at this sort of money there are probably one or two expensive time bombs lurking within it.

Commodore oil consumption
Answered by Graham Smith · 29 Sep 2012

The warranty covers you if the car has a problem, Holden is obliged to honour it and give you a car that is trouble free. Beyond that there is a requirement for any manufacturer, of any goods, to produce a product that is of commercial quality. If the oil consumption of your car doesn't improve you could claim it's not fit for the purpose for which you bought it. But I wouldn't rely on our consumer laws to get you a result.

VZ Commodore oil consumption
Answered by Graham Smith · 31 Aug 2012

The oil consumption is way too high. The engine should be pulled down to find the cause, and I would suspect that it is related to the problem you previously had with the engine.

Holden Commodore: Fuel injection issues
Answered by Graham Smith · 31 Aug 2012

We checked around and found that there are reports of fuel quality issues resulting in injectors being blocked. The issue is thought to be predominately caused by contaminants in the gas leaching plasticizers from flexible rubber hoses installed on some LPG vehicles, which then migrates to the injectors. The recommendation we were given is to inspect the car's fuel delivery lines and if they are rubber check their extractability rating. If the rating is not near zero, then have them replaced with either copper lines or zero extractable flexible lines.

Holden Commodore SS clattering on start-up
Answered by Graham Smith · 12 Oct 2012

Clattering on start-up has been an on-going problem with the V8 Commodore and yours seems to be suffering from the same problem. Change the oil before you drive it anywhere, metal particles in the oil can lead to severe engine damage if not flushed out. Also talk to the dealer about the problem and demand it be fixed under the warranty.

Holden Commodore: Difficulty starting
Answered by Graham Smith · 13 Jul 2012

It's not related to the fuel system as the Impco system starts on petrol every time, whether you've got the system switched to petrol or LPG. It's more likely to be an engine sensor, such as the crank angle sensor, which is playing up intermittently. Check the connections and the sensor itself. As for the warranty, you did the right thing in reporting while the warranty was in effect, so you could have a claim against Holden once the cause of the problem is  determined.

Commodore motor time out
Answered by Graham Smith · 23 Jul 2012

The system is designed to start on petrol every time, whether the switch is set to petrol or LPG, so there should not be any difference in starting. It sounds as though at times it could be trying to start on LPG instead of petrol. You should see an IMPCO specialist to have the ECM checked to make sure it is actually being told to start on petrol.

Commodore Omega oil usage
Answered by Graham Smith · 10 Aug 2012

It does sound as though it is using too much oil. Sit down with the dealer and work out with them how they will tackle it, and press them for a solution. Also check the oil level weekly so you don't inadvertently run out of oil.

VZ Commodore powertrain problem
Answered by Carsguide.com.au · 12 Oct 2012

It's not possible to diagnose your problem with any certainty, the mechanic is obviously checking the things that do go wrong, but hasn't clicked on the right thing yet. I would have the crank angle sensor checked.
