No car is perfect, but we've gathered everything relating to the Holden Commodore 2005 reliability here to help you decide if it's a smart buy.

Why is my 2005 Holden Commodore overheating?

Answered by CarsGuide 25 Nov 2020

There are many, many things that can make a car overheat. A faulty radiator, collapsed radiator hose, jammed thermostat, blown head gasket, low coolant level, incorrect ignition or camshaft timing, faulty fuel injectors, the list goes on and on. So you need to have the car scanned electronically to see if a fault code is offered up that could be the cause or part of the problem. First, though, I’d have a close look at the obvious stuff like a leaking radiator or blown radiator hose to make sure that it’s not a really simple fix. Even a faulty radiator cap – as simple as that sounds – can lead a car to overheat.

To be honest, a 34-dgree ambient day should never be enough to make a modern car overheat, especially not one like a Holden Commodore which was designed here to easily cope with our weather and temperature extremes.

It’s interesting to note that you bought the car from a dealer, so it would be worth going back and checking the paperwork to see if the car was sold with any warranty. It’s doubtful, however, as a 2005 model car falls outside the boundaries of Victoria’s statutory warranty legislation (generally a used car must be less than 10 years old and have travelled less than 160,000km before a statutory warranty applies from a licensed car dealer). A good mechanic who knows this type of car should be able to sort it, but have it checked soon; continuing to drive it with an overheating problem is a sure way to make small problems bigger ones.

Holden Commodore 2005: Why does it sound loud?

Answered by CarsGuide 15 Feb 2019

Without hearing the car firsthand it’s impossible to speculate on what might be wrong with your car, but I would suggest that it’s unlikely to be the spark plugs. Your best course of action would be to get a mechanic to check it for you.

Oxygen sensor on 2005 Holden Berlina

Answered by CarsGuide 25 Sep 2015

Based on your mechanic's diagnosis it would seem that the oxygen (02) sensor is probably faulty and needs replacing. There is no connection with the car's heater. If there is a problem with the heater it's different one.

Holden Commodore 2005: How to clean engine

Answered by CarsGuide 26 Jun 2015

If you have been servicing your car regularly, changing the oil and oil filter, you shouldn't have too much sludge to deal with and I would use one of the additives available for the purpose at your local automotive store. Change the oil and filter at the same time as you put the additive in, then change the oil and filter again after a week or so of driving.

Holden Commodore starter problems

Answered by CarsGuide 11 Oct 2013

That it starts fine when it's cold and enriched, but not when it's warmed up and not getting any extra fuel suggests it could be a fuelling issue. Have a mechanic check the fuel pressure; it might not be getting enough fuel on hot restarts.

Holden Commodore 2005: Faulty airbag not under warranty?

Answered by CarsGuide 22 Feb 2013

It is unusual that the airbag required replacing so soon, but the car is going on for eight years old and, as Holden said, the warranty expired some time ago. Where it was serviced wouldn't have had any influence on the failure, what Holden was telling you was that because you hadn't had it serviced at one of their dealers they would not consider a goodwill payment.

Holden Commodore: Persistent service reminder

Answered by CarsGuide 21 Dec 2012

It's a service reminder and should have been reset by the mechanic at the time of the service. Take it to a Holden dealer who should be able to do it for you.
