Holden Captiva 2012 Problems

If you can't reach a satisfactory solution to your problem going to VCAT is a way of resolving it. I couldn't predict the outcome, but as Holden has had the car for extensive periods of time trying, without success it seems, to fix it, you would seem to be justified in making a claim against them.

Assuming you have the Holden extended warranty you should be covered in the event the sunroof failed due to faulty workmanship. I've never heard of the problem you experienced before, so it's hard to speculate on the cause. If Holden does reject your warranty claim then request them to cover it under goodwill.

The negatives are in comparison with its classy rivals, including the Kia Sportage and Hyundai ix35 that - as with the Captiva - come from Korea. I've had readers complaining about quality and mechanical problems but the main shortcoming is basically its performance against the rivals.

I wouldn't recommend the Captiva but the Dualis gets The Tick and is good value. 

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.

I can't comment on the Walkinshaw chip specifically, I don't have any experience of it, but I'm not a huge fan of the chips in general as you don't really know how they achieve the results they claim, and ultimately you don't know what effect they will have on the car down the track. If you can find someone who has fitted a Walkinshaw chip you could ask them, after all first hand knowledge is the best you can get.

You have experienced the problem that is the fuel consumption guide. The fuel consumption in the ads and the guide are the results of tests done under laboratory conditions, and not necessarily an accurate guide to what might happen in real life. They are meant to be used to compare one make and model against others in the same class, they're not intended to be an outright measure of real life fuel consumption. That gives carmakers the wriggle room they need to get out of a problem when customers, like you, complain. I think you are within your rights to demand that the dealer/Holden thoroughly check your car instead of fobbing you off and make sure it is within the factory specifications. Once that is done you could test your false advertising allegation, but that's a legal question best answered by others. I do, however, have some sympathy for your view.
